Scapular dyskinesis, the impairment of optimal scapular position and motion, is common in association with shoulder injury. A comprehensive evaluation process can show the causative factors and lead to effective treatment protocols. The complexity of scapular motion and the integrated relationship between the scapula, humerus, trunk, and legs suggest a need to develop rehabilitation programs that involve all segments working as a unit rather than isolated components. This is best accomplished with an integrated rehabilitation approach that includes rectifying deficits in mobility, strength, and motor control but not overtly focusing on any one area., (Copyright © 2022 Elsevier Inc.

Parkinson disease (PD) and other related diseases with α-synuclein pathology are associated with a long prodromal or preclinical stage of disease. Predictive models based on diagnosis of idiopathic rapid eye movement (REM) sleep behavior disorder (iRBD) make it possible to identify people in the prodromal stage of synucleinopathy who have a high probability of future disease and provide an opportunity to implement neuroprotective therapies. However, rehabilitation providers may be unaware of iRBD and the motor abnormalities that indicate early motor system dysfunction related to α-synuclein pathology. Furthermore, there is no existing rehabilitation framework to guide early interventions for people with iRBD. The purpose of this work is to (1) review extrapyramidal signs of motor system dysfunction in people with iRBD and (2) propose a framework for early protective or preventive therapies in prodromal synucleinopathy using iRBD as a predictive marker. Longitudinal and cross-sectional studies indicate that the earliest emerging motor deficits in iRBD are bradykinesia, deficits performing activities of daily living, and abnormalities in speech, gait, and posture. These deficits may emerge up to 12 years before a diagnosis of synucleinopathy. The proposed rehabilitation framework for iRBD includes early exercise-based interventions of aerobic exercise, progressive resistance training, and multimodal exercise with rehabilitation consultations to address exercise prescription, progression, and monitoring. This rehabilitation framework may be used to implement neuroprotective, multidisciplinary, and proactive clinical care in people with a high likelihood of conversion to PD, dementia with Lewy bodies, or multiple systems atrophy.

Abstract: Sit-to-stand (STS) motion is one of the most important and energy-consuming basic motions in everyday life. Kinematic analysis provides information regarding what strategy or motion pattern is used by the healthy people, and through which, we can understand and obtain the law of the STS motion. The objective of this article is to study the law of STS motion through the experiment to determine a suitable description of STS motion in healthy adults, so as to provide a starting point and bases for future design and control of STS assistive devices.Thirty healthy adult subjects participated in this study and carried out STS motion experiment of standing up naturally. The STS motions were recorded using a high-definition camera. The experimentally collected kinematic data and a link segment model of the human body were used to obtain the coordinates of joints and to calculate the coordinates, velocity, and momentum of center of gravity; the postures of human body during STS are also obtained. The relationship between human body parameters and motion parameters is analyzed by using Pearson correlation method.The STS motion is divided into 4 phases; the phases are differentiated in terms of STS motion characteristics and postures, and momentum of center of gravity of human body. The main factors determining the differences in STS motion among individuals are horizontal distance between hip joint and ankle joint, lower leg length, thigh length, and the length of the transition period. The horizontal distance between hip joint and ankle joint is positively correlated with the duration from motion begin to trunk stops flexing forward (P = .021 < .05), but not so with the duration from motion begin to the end of phase 2 (P = .15 > .05).The results suggest that when designing the sit-to-stand assistive devices, one should pay attention to the whole-body posture control in STS motion, such as the posture guidance of trunk and lower leg, and should carry out specific training according to different STS phases. Sit-to-stand assistive devices should provide the same horizontal distance between hip joint and ankle joint for different individuals during the STS motion. Transition period should be properly controlled, and the degree of freedom of the lower leg should not be limited., Competing Interests: The authors report no conflicts of interest., (Copyright © 2021 the Author(s).

Objectives: To investigate the operational competences screen navigation and dwell function underlying eye gaze performance, and the relation of dystonia and choreoathetosis with eye gaze performance in children with dyskinetic cerebral palsy (DCP)., Methods: During a 5-week intervention, ten participants with DCP played eye gaze video games daily for 30 minutes. Six games were used to assess task performance, fixation count, and eye movement accuracy during four measurements. Dystonia and choreoathetosis were evaluated using the Dyskinesia Impairment Scale., Results: Eye gaze performance improved over time ( p = .013). Moderate to strong within-subject correlations were found between eye movement accuracy and task performance, and between eye movement accuracy and fixation count. No significant correlations were found with the movement disorders., Conclusions: Eye gaze technology shows great potential to be a successful computer interface for children with severe DCP, thereby potentially improving their communication skills, participation levels, and quality of life.

Parkinson's disease (PD) is the world's fastest growing neurological disorder disabling patients through a broad range of motor and non-motor symptoms. For the clinical management, a multidisciplinary approach has increasingly been shown to be beneficial. In Germany, inpatient Parkinson's Disease Multimodal Complex Treatment (PD-MCT) is a well-established and frequent approach, although data on its effectiveness are rare. We conducted a prospective real-world observational study in 47 subjects [age (M ± SD): 68.5 ± 9.0 years, disease duration: 8.5 ± 5.3 years, modified Hoehn and Yahr stage (median, IQR): 3, 2.5-3] aiming at evaluating the effectiveness of 14-day PD-MCT in terms of quality of life (Parkinson's Disease Questionnaire, EuroQol), motor [Movement Disorder Society Unified Parkinson's Disease Rating Scale Part III (MDS-UPDRS III], Timed Up and Go Test, Purdue Pegboard Test) and non-motor symptoms (revised Beck Depression Inventory). Six weeks after hospital discharge, a follow-up examination was performed. PD patients with a predominantly moderate disability level benefited from PD-MCT in terms of health-related quality of life, motor symptoms and non-motor symptoms (depression). Significant improvements were found for social support, emotional well-being and bodily discomfort domains of health-related quality of life. Sustainable improvement occurred for motor symptoms and the subjective evaluation of health state. We found a higher probability of motor response especially for patients with moderate motor impairment (MDS-UPDRS III ≥ 33). In conclusion, Parkinson's Disease Multimodal Complex Treatment improves motor symptoms, depression and quality of life. A more detailed selection of patients who will benefit best from this intervention should be examined in future studies.

Background: Goal-classification of person-centred goals, using Goal Attainment Scaling for leg spasticity treatment. Methods: The study was conducted in two phases: phase I, a retrospective review to evaluate categories of goal set in routine clinical practice. Findings were used to design a goal classification system. Phase II, a multi-centre study to confirm the goal categories. Goals set ( n  = 270) were analysed from data collected at three centres in the UK (one centre for phase I). Goal categories were mapped onto the domains of the World Health Organisation, International Classification of Functioning Disability and Health. Results: One hundred and twenty seven participants were recruited in two cohorts: phase I: 63; phase II: 64. Goal categories using both cohorts were assigned to two domains, each subdivided into three key goal categories: Domain 1 : body structure impairment 121 (44%): (a) pain/discomfort 34 (12%), (b) involuntary movements 20 (7%), and (c) range of movement/contracture prevention 67 (25%). Domain 2 : activity function 149 (56%): (a) passive function (ease of caring for the affected limb) n  = 89 (33%), (b) active function (transfers) 26 (10%), and (c) active function (mobility) 27 (10%), other n  = 7 (3%). Conclusions: Patients individual leg spasticity goals can be grouped into six categories and two domains, which will assist clinicians, patients and cares in setting and evaluating goals in practice. Implications for Rehabilitation Six goal areas used in clinical goal setting for leg spasticity management were identified, under the two domains: (1) body structure impairment: pain, involuntary movements, and range of movement and (2) activities/function: passive function (ease of caring), active function - transfers or standing and active function - mobility. Categorisation of goals is consistent on repeated evaluation and across different clinical services. Using clinical goals for leg spasticity treatment is an effective method to identify treatment priorities.

Study Design: Crossover repeated-measure design., Introduction: Scapular dyskinesis rehabilitation programs that focus on inhibiting upper trapezius (UT) and activating the lower trapezius (LT) may assist in restoring scapular movements. We hypothesized that taping may be able to normalize scapular movements and associated muscular recruitment., Purpose of the Study: The purpose of this study was to investigate the immediate effects of kinesio taping over trapezius on scapular kinematics and muscular activation in different dyskinesis patterns. We expected that taping can improve scapular kinematics and muscular activation in subjects with dyskinesis., Methods: Fifty-four participants with inferior angle prominence (pattern I), medial border prominence (pattern II), and mixed pattern (pattern I + II) were recruited. Kinesio taping was applied over 3 parts of trapezius muscles, including UT, middle trapezius (MT), and LT. The scapular kinematics and electromyographic data of trapezius and serratus anterior were collected during scapular plane elevation without taping and after each taping application., Results: UT taping decreased UT activity (5%-7%; P = .001-.003) in 72% of participants with pattern II and pattern I + II dyskinesis, with increased posterior tipping (2.2°-2.5°; P = .003) in pattern II dyskinesis. MT taping increased UT activity (3%; P = .003) in 48% of participants with pattern II dyskinesis., Discussion: The taping over the trapezius muscle may help to restore coordinated scapular muscle balance and increased upward rotation of the scapula, especially in pattern II dyskinesis. Although no electromyography or kinematic difference was found with LT taping in each dyskinesis pattern, methods of applying LT taping need to be further investigated., Conclusion: Reduced UT muscle activity and scapular posterior tipping are appropriate when applying taping over UT muscle in patterns II and I + II dyskinesis. Caution should be taken when applying taping over MT and LT muscles in terms of increased UT activity, especially in pattern II dyskinesis., (Copyright © 2017 Hanley & Belfus.

Objective: This study aims to develop an assistive technology-180° rotating feeding spoon that could improve the ability of eating of self-care patients with upper extremity dyskinesia., Methods: The Brunnstrom 6-stage rating of hemiplegia was adopted. During the different recovery stages of the upper limbs, the patients orally ate using a feeding spoon with a non-rotatory head and a 180° rotating feeding spoon. The ability of these patients to eat by themselves was observed, and the basic activity of daily living (BADL) was assessed using the Barthel index (BI)., Results: The Brunnstrom assessment scale was used to analyze the results of the patient's upper limb function examination, and the results revealed that the 180° rotating feeding spoon could assist patients with different degrees of upper limb dysfunction when eating independently., Conclusions: The 180° rotating feeding spoon can assist patients with upper limb dysfunction when eating independently. For patients with different degrees of upper limb dysfunction, the spoon can provide different degrees of aid.

Objective: To retrospectively analyze the effects of our original combination therapy treatment on patients with nonodontogenic persistent dentoalveolar pain., Methods: Twenty-one patients suffering from persistent dentoalveolar pain (nineteen females and two males; mean age ± standard deviation: 55.7 ± 19.6 years) participated in this study. They were treated with a therapy combination of jaw exercise and psychoeducation to reduce oral parafunctional activities every month. The intensity of pain in these subjects was evaluated using a numerical rating scale (NRS) before and after treatment., Results: The NRSs at the baseline ranged from 5 to 10 (median, 8), from 0 to 10 (median, 2) at one month after treatment, from 0 to 10 (median, 1) at three months after treatment, and from 0 to 10 (median, 0) at the end of treatment. Pain intensity after treatment improved significantly., Conclusion: There was a significant reduction in pain after our combination of therapies as nonpharmacological treatments, and therefore this treatment could be useful in the management of NPDP patients.

Excess involuntary movements and slowness of movement in children with dyskinetic cerebral palsy often result in the inability to properly interact with augmentative and alternative communication (AAC) devices. This significantly limits communication. It is, therefore, essential to know how to adjust the device layout in order to maximize each child's rate of communication. The aim of this paper was to develop a mathematical model to estimate the information rate in children with dyskinetic cerebral palsy and to determine the optimal AAC layout for a touchscreen tablet that results in enhanced speed of communication. The model predicts information rate based on button size, number, spacing between buttons, and the probability of making an error or missing target buttons. Estimation of the information rate confirmed our hypothesis of lower channel capacity in children with dyskinetic cerebral palsy compared with age-matched healthy children. Information rate increased when the AAC layout was customized based on the optimal parameters predicted by the model. In conclusion, this paper quantifies the effect of motor impairments on communication with assistive communication devices and shows that communication performance can be improved by optimally matching the parameters of the AAC touchscreen device to the abilities of the child.

Objective: To systematically evaluate the clinical effect of high frequency repeated transcranial magnetic stimulation(HF rTMS)therapy on dyskinesia in patients with incomplete spinal cord injury., Methods: Randomized controlled trials(RCTs) about HF rTMS therapy on patients with motor incomplete spinal cord injury were searched electronically in PubMed, Google scholar, Cochrane library, Clinical trial, Medline, Web of science, CNKI, VIP, and Wanfang database before October 2016. Two reviewers independently screened the literatures according to the inclusion and exclusion criteria, as well as extracted the data and assessed the methodological quality. The observed outcomes included ASIA motor score, ASIA lower extremities motor score(LEMS), Modified Ashworth score (MAS), Ten-meter walking test (10MWT) and Walking index for SCI II(WISCI II), and the outcomes were analyzed using RevMan5.2 software provided by the Cochrane information management system., Results: Five RCTs involved 103 patients were included, and 61 patients(experimental group) accepted real rTMS and physical rehabilitation care for SCI, 51 patients(control group) accepted only physical rehabilitation care. There were significant differences in ASIA motor score, LEMS and 10MWT between two groups after HF rTMS therapy (statistics were Z =2.96, P =0.003; Z =3.04, P =0.002; Z =2.16, P =0.03; respectively). When stimulating the leg motor cortex, there was significant difference in MAS between two groups( Z =2.79, P =0.005), and when stimulating the vertex, there was no significant difference( Z =0.09, P =0.93). There was no significant difference in WISCI IIscore after HF rTMS therapy between two groups( Z =0.90, P =0.37)., Conclusions: HF rTMS can raise motor score in patients with incomplete spinal cord injury, improve the spasticity of the lower extremities, and increase the motor ability., Competing Interests: The authors of this article and the planning committee members and staff have no relevant financial relationships with commercial interests to disclose., (Copyright© 2018 by the China Journal of Orthopaedics and Traumatology Press.)

Background: Some stroke survivors suffer from involuntary movement, which often disturbs upper-limb function, but there are few effective modality options., Case Report: A 70-year-old man presented with persisting right-upper-limb hemiballism due to left thalamic hemorrhage ten years before. We provided inpatient rehabilitation, including repetitive-facilitative exercise and task-related training, and prescribed clonazepam from day 5 after admission. However, the affected upper limb showed no significant change and remained nonfunctional. When we introduced mirror therapy (MT) to the rehabilitation program on day 14, hemiballism immediately decreased during the MT session, so we added daily MT sessions of 20 min/day. At discharge on day 42, he was able to use his right hand for eating meals and folding laundry., Clinical Rehabilitation Impact: This shows that MT may have the potential to be a novel therapeutic method for treating involuntary movement. Further research is needed to elucidate mechanisms by which MT may reduce hemiballism.

We report a case of a patient with profound right-sided hemiballismus resulting from an acute unilateral left thalamic lesion. The hemiballismus was significant and persistent, resulting in profound functional disability. We discuss the use of low-dose haloperidol in conjunction with acute rehabilitation in the treatment of hemiballismus, resulting in decreased amplitude and frequency of adventitious movements and leading to substantial functional gains in our patient. To our knowledge, this is the first extensive report of successful rehabilitation of a patient with functionally disabling hemiballismus., Level of Evidence: V., (Copyright © 2017 American Academy of Physical Medicine and Rehabilitation.

Objective: To establish the impact of a gaze-based assistive technology (AT) intervention on activity repertoire, autonomous use, and goal attainment in children with severe physical impairments, and to examine parents' satisfaction with the gaze-based AT and with services related to the gaze-based AT intervention., Methods: Non-experimental multiple case study with before, after, and follow-up design. Ten children with severe physical impairments without speaking ability (aged 1-15 years) participated in gaze-based AT intervention for 9-10 months, during which period the gaze-based AT was implemented in daily activities., Results: Repertoire of computer activities increased for seven children. All children had sustained usage of gaze-based AT in daily activities at follow-up, all had attained goals, and parents' satisfaction with the AT and with services was high., Discussion: The gaze-based AT intervention was effective in guiding parents and teachers to continue supporting the children to perform activities with the AT after the intervention program.

Stabilization exercises have been a focus and mainstay of many therapeutic and performance training programs in the past decade. Whether the focus is core stabilization for the spine or scapular stabilization, clinicians and trainers alike have endorsed these programs, largely on the basis of conceptual theory and anecdotal experience. The notion that an unstable scapula is related to shoulder dysfunction and pathology is well accepted, but is it accurate? The aim of this perspective article is to challenge the concept of scapular stabilization through the application of biomechanical and motor control constructs. The objectives are to critically examine current beliefs about scapular stabilization, to discuss definitions of stabilization and stability in the context of the scapulothoracic region, and to evaluate key evidence regarding scapular stabilization and scapular dyskinesia. Several new approaches that may affect the understanding of normal and atypical scapula motion are explored. Finally, a historical analogy is presented and future research and clinical directions are suggested. The aims are to lead readers to the essential concepts implied on scapular stabilization, to increase the critical thought process in rehabilitation practice, and to suggest some open topics to be explored in future research., (© 2016 American Physical Therapy Association.)

Scapular dyskinesis, characterized by scapular downward rotation syndrome (SDRS) affects scapula-humeral rhythm and results in shoulder dysfunction. Previous study has led to the recommendation of standard shrug exercise to contend with SDRS and strengthen the upper trapezius (UT) muscle. However, few researchers have examined which shrug exercise is most effective. The aim of this research was to compare scapular kinematic changes and scapular rotator muscles activity across three different shrug exercises in SDRS. The amounts of scapular downward rotation were measured by a caliper and the scapular upward rotation angle was measured using two digital inclinometers. Surface electromyography was used to measure EMG amplitude from the UT, lower trapezius (LT), serratus anterior (SA), and levator scapula (LS). Seventeen subjects with SDRS were recruited for this study. The subjects performed three shrug exercises with 30° shoulder abduction (preferred shrug, frontal shrug, and stabilization shrug). The stabilization shrug showed a significantly greater scapular upward rotation angle compared with the preferred shrug (P=0.004) and frontal shrug (P=0.006). The UT activity was significantly greater in the frontal shrug than in the preferred shrug (P=0.002). The UT/LS muscle activity ratio was also significantly greater in the frontal shrug than in the preferred shrug (P=0.004). The stabilization shrug should be preferred to enhance the upward rotation angle. In addition, the frontal shrug can be used as an effective method to increase UT activity and to decrease LS activity in SDRS., (Copyright © 2015 Elsevier B.V. All rights reserved.)

Purpose: Scapular dyskinesis has been related to acromioclavicular injuries. A rehabilitation protocol has been studied in order to treat scapular dyskinesis, but it has not yet been evaluated. This rehabilitation programme was adopted to improve the shoulder function, thereby improving the scapular dyskinesis in patients with chronic acromioclavicular dislocation., Method: Twenty-four patients diagnosed with chronic type III acromioclavicular dislocation and scapular dyskinesis that have already been conservatively treated were enrolled in the rehabilitation protocol and analysed. Fourteen of these patients had a Scapular Inferior Coracoid dysKinesis (SICK) Syndrome. The adopted rehabilitation protocol consisted of 12 strengthening and stretching exercises of the scapulae. The final follow-ups were performed after 6 weeks, 6 months and 12 months using clinical measurements of scapular position and clinical evaluation of the scapular motion. In order to evaluate the SICK scapula syndrome, we used the SICK Scapula Rating Scale. The shoulder function was evaluated with a Constant Score and a Subjective Shoulder Value., Results: After 12 months, the follow-up concluded that the scapular dyskinesis was no longer present in 18/23 patients (78.2 %). SICK scapula syndrome was observed in 4/8 patients with a scapular malposition. The Scapula Rating Scale score in 4 patients with SICK scapula was 7.5 points. After 12 months of rehabilitation, the mean Constant Score and Subjective Shoulder Value grew up to 85 points., Conclusion: The scapular dyskinesis and SICK syndrome secondary to chronic type III AC dislocation can be treated with the proposed rehabilitation protocol resulting in positive improvements of the shoulder function within 6 weeks; however, patients that do not respond to the rehabilitation programme will not improve with extended rehabilitation time. It is important to advise patients of the specific exercises for the prevention/treatment of scapular dyskinesis in the rehabilitation programme after AC joint dislocation., Level of Evidence: IV.

Although studies have demonstrated that several specific brain lesions are related to the severity of functional outcomes, the effects of specific brain lesions are not yet clear. This study investigated the effects of hemorrhagic stroke lesions on motor recovery. Eleven subjects with hemorrhagic stroke were assessed. Using the Fugl-Meyer Assessment and functional ambulation category, clinical motor and sensory impairments were tested four times in total: initially within 2 weeks and 1, 3, and 6 months after the onset of stroke. Brain lesions and size were evaluated using MRIcron, SPM8, and Talairach Daemon software. Trunk control, motor function in the lower limbs, and sensory function improved significantly within 3 months, after which the change was no longer significant. Upper limb function and gait were unchanged within 1 month but improved significantly 3 months after onset and continued to improve for 6 months. Involvement of the anterior putamen, internal capsule, thalamus, periventricular white matter, and premotor cortex was related to poor upper limb recovery in patients with hemorrhagic stroke. These results should be useful for planning rehabilitation strategies and understanding the prognosis of hemorrhagic stroke.

The scapula functions as a bridge between the shoulder complex and the cervical spine and plays a very important role in providing both mobility and stability of the neck/shoulder region. The association between abnormal scapular positions and motions and glenohumeral joint pathology has been well established in the literature, whereas studies investigating the relationship between neck pain and scapular dysfunction have only recently begun to emerge. Although several authors have emphasised the relevance of restoring normal scapular kinematics through exercise and manual therapy techniques, overall scapular rehabilitation guidelines decent for both patients with shoulder pain as well as patients with neck problems are lacking. The purpose of this paper is to provide a science-based clinical reasoning algorithm with practical guidelines for the rehabilitation of scapular dyskinesis in patients with chronic complaints in the upper quadrant.

The second international consensus conference on the scapula was held in Lexington Kentucky. The purpose of the conference was to update, present and discuss the accumulated knowledge regarding scapular involvement in various shoulder injuries and highlight the clinical implications for the evaluation and treatment of shoulder injuries. The areas covered included the scapula and shoulder injury, the scapula and sports participation, clinical evaluation and interventions and known outcomes. Major conclusions were (1) scapular dyskinesis is present in a high percentage of most shoulder injuries; (2) the exact role of the dyskinesis in creating or exacerbating shoulder dysfunction is not clearly defined; (3) shoulder impingement symptoms are particularly affected by scapular dyskinesis; (4) scapular dyskinesis is most aptly viewed as a potential impairment to shoulder function; (5) treatment strategies for shoulder injury can be more effectively implemented by evaluation of the dyskinesis; (6) a reliable observational clinical evaluation method for dyskinesis is available and (7) rehabilitation programmes to restore scapular position and motion can be effective within a more comprehensive shoulder rehabilitation programme.

The scapula plays a crucial role for proper shoulder function, serving as a stable base for rotator cuff activation and as a link in the kinetic chain. Joint, ligament or muscular problems near the scapula can lead to malpositions or to an altered movement pattern. This abnormal situation is called "scapular dyskinesis", which appears to be a non-specific response to a painful condition of the shoulder. The clinical examination of the scapula is crucial for every patient presenting a painful shoulder. Systematic observation and testing enable the practitioner to detect subtle static and dynamic abnormalities. Visual evaluation, objective measurements and corrective manoeuvres can evaluate the role of the "scapular dyskinesis" in the shoulder painful condition. The scapular rehabilitation will address muscular retractions and imbalances and restore a good dynamic stability, starting with analytical work, and evolving into more functional and specific exercises.

Objective: To explore the impacts of acupuncture and rehabilitation on post-stroke abnormal patterns of limb movement and evaluate them via rehabilitation method., Methods: Ninety cases of post-stroke movement disorder were randomly divided into an acupuncture-rehabilitation group, a body acupuncture group and a medication group, 30 cases in each group. In medication group, the conventional medication in neurological department was administered. In acupuncture-rehabilitation group and body acupuncture group, on the basis of the therapy as medication group, scalp acupuncture (such as parietal area and anterior parietal area, etc.), rehabilitation training and traditional body acupuncture [such as Jianyu (LI 15) and Fengshi (GB 31),etc.] were supplemented. The continuous electric stimulation was applied in body acupuncture group. The treatment lasted for 8 weeks. The assessment of clinical efficacy, Fugl-Meyer score, Modified Ashworth scale (MAS), range of motion (ROM) and shoulder pain score were taken as observation indices for rehabilitation evaluation before and after treatment in each group., Results: The effective rate was 93.1% (27/29) in acupuncture-rehabilitation group, which was superior to 66.7% (20/30) in body acupuncture group and 57.1% (16/28) in control group (both P<0.01) separately. After treatment, Fugl-Meyer score, MAS, ROM of the lower limbs and shoulder joint and shoulder pain score (except medication group) were all remarkably improved as compared with those before treatment in each group (all P<0.01). The improvements in Fugl-Meyer score, MAS, ROM of the upper limbs and shoulder pain score in acupuncture-rehabilitation group were significantly superior to those in body acupuncture group and medication group (P<0.05, P<0.01)., Conclusion: Acupuncture and rehabilitation therapy and traditional body acupuncture remarkably improve in post-stroke movement disorder. But acupuncture and rehabilitation therapy is apparently superior to traditional body acupuncture. This therapy can effectively prevent and treat post-stroke abnormal patterns and it is greatly significant in the improvement of survival quality for the patients.

Hypothesis: This study tested the hypothesis that infraspinatus strength in professional volleyball players can be assessed with the scapula free (infraspinatus strength test, IST) and with the scapula retracted (infraspinatus scapula retraction test, ISRT) before and after scapular musculature training., Materials and Methods: A prospective study was performed in 31 professional volleyball players. Isometric strength (kg) of the infraspinatus with IST and with ISRT was recorded by a handheld dynamometer and compared with the values found after 3 and 6 months of rehabilitation. Magnetic resonance imaging was performed to exclude articular and cuff pathology. Pain scores were assessed using a visual analog scale., Results: The mean increase in the force values of IST was statistically significant after 3 months (P < .01) and 6 months (P < .001) of rehabilitation. The mean difference between IST and ISRT decreased from 4.72 ± 0.007 before rehabilitation to 1.2 ± 0.26 at 3 months and to 0.4 ± 0.006 at 6 months. The mean score for pain was 2.4 ± 1.8 at 3 months and 2.6 ± 1.4 at 6 months., Discussion: Acquired scapular dyskinesis in overhead athletes can lead to the rotator cuff weakness. Inhibition due to pain and the negative biomechanic effect of scapular dyskinesis results in specific infraspinatus dysfunction that arise with the ISRT., Conclusions: ISRT is practical and consistent to assess the infraspinatus strength in overhead athletes with scapular dyskinesis. A functional rehabilitation protocol, designed to restore scapular muscles balance and shoulder mobility, is essential in the training program to prevent shoulder dysfunction and improve sports performance., (Copyright © 2010 Journal of Shoulder and Elbow Surgery Board of Trustees.

Background: Experiencing independent mobility is important for children with a severe movement disability, but learning to drive a powered wheelchair can be labor intensive, requiring hand-over-hand assistance from a skilled therapist., Methods: To improve accessibility to training, we developed a robotic wheelchair trainer that steers itself along a course marked by a line on the floor using computer vision, haptically guiding the driver's hand in appropriate steering motions using a force feedback joystick, as the driver tries to catch a mobile robot in a game of "robot tag". This paper provides a detailed design description of the computer vision and control system. In addition, we present data from a pilot study in which we used the chair to teach children without motor impairment aged 4-9 (n = 22) to drive the wheelchair in a single training session, in order to verify that the wheelchair could enable learning by the non-impaired motor system, and to establish normative values of learning rates., Results and Discussion: Training with haptic guidance from the robotic wheelchair trainer improved the steering ability of children without motor impairment significantly more than training without guidance. We also report the results of a case study with one 8-year-old child with a severe motor impairment due to cerebral palsy, who replicated the single-session training protocol that the non-disabled children participated in. This child also improved steering ability after training with guidance from the joystick by an amount even greater than the children without motor impairment., Conclusions: The system not only provided a safe, fun context for automating driver's training, but also enhanced motor learning by the non-impaired motor system, presumably by demonstrating through intuitive movement and force of the joystick itself exemplary control to follow the course. The case study indicates that a child with a motor system impaired by CP can also gain a short-term benefit from driver's training with haptic guidance.

Background: Most studies of bilateral arm training (BAT) did not employ a randomized controlled trial design and involved very limited functional training tasks., Objective: Compare the effects of BAT with control intervention (CI) on motor control and motor performance of the upper extremity and also functional gains in patients with chronic stroke., Methods: . This 2-group randomized controlled trial with pretreatment and posttreatment measures enrolled 33 stroke patients (mean age = 53.85 years) 6 to 67 months after onset of a first stroke. They received either a BAT program concentrating on both upper extremities moving simultaneously in functional tasks by symmetric patterns or CI (control treatment) for 2 hours on weekdays for 3 weeks. Outcome measures included kinematic analyses assessing motor control strategies for unilateral and bimanual reaching and clinical measures involving the Fugl-Meyer Assessment (FMA) of motor-impairment severity and the Functional Independence Measure (FIM) and the Motor Activity Log (MAL) evaluating functional ability., Results: After treatment, the BAT group showed better temporal and spatial efficiency during unilateral and bilateral tasks and less online error correction only during the bilateral task than the control group. The BAT group showed a significantly greater improvement in the FMA than the control group but not in the FIM and MAL., Conclusions: Relative to CI, BAT improved the spatiotemporal control of the affected arm in both bilateral and unilateral tasks, decreased online corrections to perform bilateral tasks, and reduced motor impairment. These findings support the use of BAT to improve motor control and motor function of the affected upper limb in stroke patients.

Background: Unilateral middle cerebral artery infarction has been reported to impair bilateral hand grasp., Methods: Individuals (5 males and 5 females; age 33-86 years) with chronic unilateral middle cerebral artery stroke (4 right lesions and 6 left lesions) repeatedly lifted a 260-g object. Participants were then trained to lift the object using visuomotor feedback via an oscilloscope that displayed their actual grip force (GF) and a target GF, which roughly matched the physical properties of the object., Results: The subjects failed to accurately modulate the predictive GF when relying on somatosensory information from the previous lifts. Instead, for all the lifts, they programmed excessive GF equivalent to the force used for the first lift. The predictive GF was lowered for lifts following the removal of the visual feedback. The mean difference in predictive GF between the lifts before and after visual training was significant (4.35 +/- 0.027 N; P

Background: Cognitive deficits impede stroke recovery. Aerobic exercise (AEX) improves cognitive executive function (EF) processes in healthy individuals, although the learning benefits after stroke are unknown., Objective: To understand AEX-induced improvements in EF, motor learning, and mobility poststroke., Methods: Following cardiorespiratory testing, 38 chronic stroke survivors were randomized to 2 different groups that exercised 3 times a week (45-minute sessions) for 8 weeks. The AEX group (n = 19; 9 women; 10 men; 64.10 +/- 12.30 years) performed progressive resistive stationary bicycle training at 70% maximal heart rate, whereas the Stretching Exercise (SE) group (n = 19; 12 women; 7 men; 58.96 +/- 14.68 years) performed stretches at home. Between-group comparisons were performed on the change in performance at "Post" and "Retention" (8 weeks later) for neuropsychological and motor function measures., Results: VO(2)max significantly improved at Post with AEX (P = .04). AEX also improved motor learning in the less-affected hand, with large effect sizes (Cohen's d calculation). Specifically, AEX significantly improved information processing speed on the serial reaction time task (SRTT; ie, "procedural motor learning") compared with the SE group at Post (P = .024), but not at Retention. Also, at Post (P = .038), AEX significantly improved predictive force accuracy for a precision grip task requiring attention and conditional motor learning of visual cues. Ambulation and sit-to-stand transfers were significantly faster in the AEX group at Post (P = .038), with balance control significantly improved at Retention (P = .041). EF measurements were not significantly different for the AEX group., Conclusion: AEX improved mobility and selected cognitive domains related to motor learning, which enhances sensorimotor control after stroke.

Turning is an impaired activity in persons with Parkinson's disease (PwPD). The current study examines the turning characteristics in PwPD (9 freezers and 10 nonfreezers) and 9 controls, and explores the effect of rhythmic auditory cues while turning. Turning parameters were collected from a 180 degrees left U-turn during a noncued and a cued condition, using a 3D measuring system. Auditory cues were supplied with a metronome at a rhythm equaling the subject's comfortable step frequency during straight line walking. Results showed that in contrast to controls, PwPD used a wider turning-arc and took smaller, narrower steps. In addition, they demonstrated a higher Coefficient of Variation (CV) of step duration (6.92%) compared to controls (4.88%, P < 0.05). The "wide-arc" turning strategy of PwPD was more prominent in freezers than in nonfreezers. Auditory cues reduced the CV of step duration in PwPD (both freezers and nonfreezers) during turning (from 6.92 to 6.00%, P < 0.05). In summary: Cueing reduced the gait-timing variability during turning, but PwPD maintained a wider arc to turn compared with controls., (2007 Movement Disorder Society)

A 61-year-old man with Parkinson's disease (PD), motor fluctuations, and dyskinesias underwent bilateral implantation of deep brain stimulation (DBS) electrodes in the subthalamic nucleus (STN). One month after surgery, DBS was optimized to bilateral monopolar settings at the most proximal electrode just superior to the STN, which improved motor fluctuations and dyskinesias. At several postoperative evaluations off medications overnight, both stimulators were turned off and within 60 seconds he developed severe dyskinesias. When the stimulators were turned back on, the dyskinesias soon resolved. This article is a first report of a unique pattern of rebound-type dyskinesia that occurred in the off medication state produced by stopping STN DBS., ((c) 2006 Movement Disorder Society.)

It is well known that applying vibrations to men influences multiple physiological functions. The authors analysed post effects of whole-body-vibration (WBV) on motor symptoms in Parkinson's disease (PD). Sixty-eight persons with PD were randomly subdivided into one experimental and one control group. Motor symptoms were assessed by the UPDRS (Unified Parkinson's Disease Rating Scale) motor score. A cross-over design was used to control treatment effects. The treatment consisted of 5 series of whole-body-vibration taking 60 seconds each. On average a highly significant (p<0.01) improvement of 16.8% in the UPDRS motor score was found in the treatment group. Only marginal changes (p>0.05) were found in the control group. The cross-over procedure showed comparable treatment effects (14.7% improvement after treatment). With respect to different symptom clusters only small changes were found in limb akinesia and cranial symptoms. By contrast, tremor and rigidity scores were improved by 25% and 24%, respectively. According to the structure of symptom changes it is unlikely that these effects are explainable on peripheral sensory level, exclusively. With respect to the findings of other studies one can speculate about changes in activation of the supplementary motor area and in neurotransmitter functions.

Alien hand syndrome (AHS) is a rare syndrome characterized by involuntary, uncontrollable, and purposeless movement of one upper limb, which is considered as extraneous by the patient. The term AHS was previously used to describe a syndrome due to lesions in the anterior corpus callosum. Successively, some authors reported cases of AHS in patients due to posterior cerebral lesions, without lesions of the corpus callosum. Thus, it was possible to distinguish the posterior variant of AHS from the anterior form. The authors report an unusual case of posterior AHS due to a unique parieto-occipital lesion of the dominant hemisphere. However, the patient showed clinical findings that were similar to the anterior AHS. The rehabilitative treatment, individualized and targeted toward the specific needs of the patient, allowed the improvement of the patient's participation in activities of daily living.

Unlabelled: This self-directed learning module highlights several movement disorders. These include dystonia, chorea, tremors, and myoclonus. A description of the clinical presentation and associated disease processes is presented. Although the discussion on treatment focuses on pharmacologic intervention, surgical options are presented when appropriate. Other movement disorders (ie, parkinsonism) are discussed elsewhere in the Study Guide., Overall Article Objectives: (a) To define the various symptoms and etiologies of dystonia; (b) to define chorea and its treatment; (c) to define tremors, including associated neurologic disorders, plus pharmacologic and potential surgical interventions; and (d) to describe the symptoms, classification, and treatment of primary and secondary myoclonus.

Purpose: The objective of this study was to investigate the influence of an intensive exercise training on motor disability, mood, and subjective well-being in parkinsonian patients., Methods: The study was designed as an open long-term pilot trial over 20 wk. Sixteen slightly to moderately affected idiopathic parkinsonian patients (PD) were included. An intensive standardized exercise training was performed twice weekly over 14 wk in all patients. Evaluations were performed before the start of the study (exam. 1), after 7 wk (exam 2), 14 wk (exam 3), and 20 wk (exam 4/long-term effect). The test battery included: 1) basic motor test (BMT) [test for muscle strength, flexibility, and coordination]; 2) Unified Parkinson's Disease Rating Scale (UPDRS) and Columbia University Rating Scale (CURS) for PD-specific motor disability; and 3) registration of psychometric data by Mini Mental State (MMS) for dementia and the Adjective Mood Questionnaire of Zeersen (AMQZ) and Sickness Impact Profile (SIP) for subjective well-being., Results: UPDRS sigma score (P < 0.0001), CURS sigma score (P < 0.0001) and BMT 2 score (P < 0.0001) improved significantly by exercise training. Six weeks after termination of the training program, the majority of the patients had lost only minor components of their regained motor skills. There was no significant change in cognitive function during the study. The results of open interviews referring to subjective well-being were confirmed by the AMQZ and SIP. As an unexpected side effect, dyskinesias seemed to be better controlled., Conclusion: Motor disability as well as mood and subjective well-being can be clearly improved by intensive sports activities in early to medium stage PD patients. A sustained ongoing benefit outlasting the active training period for at least 6 wk can be achieved but the exact duration of this benefit is open.
