Dysphagia has been reported to be associated with the descent of the hyolaryngeal complex. Further, suprahyoid muscles play a greater role than infrahyoid muscles in elevation of the hyolarngeal complex. Respiratory muscle training (RMT) can improve lung function, and expiratory muscle strength training can facilitate elevation of the hyoid bone and increase the motor unit recruitment of submental muscles during normal swallowing. This study aimed to investigate the surface electromyography (sEMG) of the swallowing muscles, bilaterally, and the effect of RMT on swallowing muscles in stroke patients with respiratory muscle weakness.Forty patients with first episode of unilateral stroke were included in this retrospective controlled trial. After exclusion of 11 patients with respiratory muscle strength stronger than 70% of the predicted value, 15 were allocated to the RMT group and 14 to the control group. However, eventually, 11 patients in RMT group and 11 patients in control group completed the study. The sEMG of the orbicularis oris, masseter, submental, and infrahyoid muscles were recorded during dry swallowing, water swallowing (2 mL), and forced exhalation against a threshold breathing trainer set at different intensities, at baseline and after 6-week RMT.Regarding the sEMG of submental muscles, there were significant between-group differences on the latency of the unaffected side (P = .048), significant change from baseline force on the unaffected side (P = .035), and significant between-side difference (P = .011) in the RMT group during dry swallowing. Significant change in the duration from baseline was observed on the affected side of the RMT group when blowing was set at 50% maximal expiratory pressure (MEP; P = .015), and on the unaffected side of the control group when blowing set at 15% MEP (P = .005). Significant difference was observed in the duration between 50% MEP and 15% MEP after 6-week program in the control group (P = .049).A 6-week RMT can improve the electric signal of the affected swallowing muscles with more effect on the unaffected side than on the affected side during dry swallowing. Furthermore, RMT with 50% MEP rather than 15% MEP can facilitate greater submental muscle activity on the affected side in stroke patients with respiratory muscle weakness.

The relationship between left ventricular ejection fraction (LVEF) and cardiovascular (CV) outcome is documented in patients with low LVEF. Ventilatory inefficiency is an important prognostic predictor. We hypothesized that the presence of ventilatory inefficiency influences the prognostic predictability of LVEF in heart failure (HF) outpatients. In total, 169 HF outpatients underwent the cardiopulmonary exercise test (CPET) and were followed up for a median of 9.25 years. Subjects were divided into five groups of similar size according to baseline LVEF (&le, 39%, 40&ndash, 58%, 59&ndash, 68%, 69&ndash, 74%, and &ge, 75%). The primary endpoints were CV mortality and first HF hospitalization. The Cox proportional hazard model was used for simple and multiple regression analyses to evaluate the interrelationship between LVEF and ventilatory inefficiency (ventilatory equivalent for carbon dioxide (VE/VCO2) at anaerobic threshold (AT) &gt, 34.3, optimized cut-point). Only LVEF and VE/VCO2 at AT were significant predictors of major CV events. The lower LVEF subgroup (LVEF &le, 39%) was associated with an increased risk of CV events, relative to the LVEF &ge, 75% subgroup, except for patients with ventilatory inefficiency (p = 0.400). In conclusion, ventilatory inefficiency influenced the prognostic predictability of LVEF in reduced LVEF outpatients. Ventilatory inefficiency can be used as a therapeutic target in HF management.

MINI: In this study, respiratory function at the time of extubation can be useful optimal clinical guidelines for weaning and extubation attempts in patients with acute cervical spinal cord injury. Serum thiobarbituric acid-reactive substances level at admission can be a useful predictor for severity in acute cervical patients with spinal cord injury.Patients who had suffered from acute blunt cervical spinal cord injury (SCI) and admitted our hospital within 24 hours after injury were included in the study.We compared the respiratory function and serum reactive oxidative stress (ROS) after acute cervical SCI, and tried to find out the valuable predictors of weaning in patients with acute cervical SCI.Ventilation impairment is a major complication of acute cervical SCI. Evidence of oxygen radical formation in secondary injury from animal SCI models demonstrates an immediate postinjury increase in ROS production after SCI. We hypothesize that the serum ROS is associated with the severity of patients with acute cervical SCI.Thirty-eight adult patients who had acute cervical SCI and 58 healthy volunteers were enrolled. Respiratory function at admission, at the time of extubation and at 48 hours after extubation, serum oxidative stress, Injury Severity Score and Japanese Orthopaedic Association score at admission were compared.The most notable predictor of mechanical ventilation more than 48 hours was serum thiobarbituric acid-reactive substances (TBARS) level at admission (P = 0.027), and the cut-off value of serum TBARS level was 731.7 μmol/L (sensitivity 87.5% and specificity 78.9%). For the reventilation ≤5 days, the notable predictors were respiratory function at the time of extubation (maximal inspiratory pressure, P = 0.040; maximal expiratory pressure, P = 0.020; and tidal volume, P = 0.036) and serum TBARS level at admission (P = 0.013), the cut-off value of serum TBARS level at admission was 762.3 μmol/L (sensitivity 100% and specificity 90.0%).In this study, respiratory function (maximal inspiratory pressure, maximal expiratory pressure, and tidal volume) at the time of extubation can be useful optimal clinical guidelines for weaning and extubation attempts in patients with acute cervical SCI. Serum TBARS level at admission can be a useful predictor for severity in acute cervical SCI patients.3.Patients who had suffered from acute blunt cervical spinal cord injury (SCI) and admitted our hospital within 24 hours after injury were included in the study.

Background: respiratory complications are a leading cause of morbidity and mortality in individuals with spinal cord injury (SCI). We examined the effects of respiratory muscle training (RMT) in patients with acute cervical SCI. Methods: this prospective trial enrolled 44 adults with acute cervical SCI, of which twenty received RMT and twenty-four did not receive RMT. Respiratory function, cardiovascular autonomic function, and reactive oxidative species (ROS) were compared. The experimental group received 40-min high-intensity home-based RMT 7 days per week for 10 weeks. The control group received a sham intervention for a similar period. The primary outcomes were the effects of RMT on pulmonary and cardiovascular autonomic function, and ROS production in individuals with acute cervical SCI. Results: significant differences between the two groups in cardiovascular autonomic function and the heart rate response to deep breathing (p = 0.017) were found at the 6-month follow-up. After RMT, the maximal inspiratory pressure (p = 0.042) and thiobarbituric acid-reactive substances (TBARS) (p = 0.006) improved significantly, while there was no significant difference in the maximal expiratory pressure. Significant differences between the two groups in tidal volume (p = 0.005) and the rapid shallow breathing index (p = 0.031) were found at 6 months. Notably, the SF-36 (both the physical (PCS) and mental (MCS) component summaries) in the RMT group had decreased significantly at the 6-month follow-up, whereas the clinical scores did not differ significantly (p = 0.333) after RMT therapy. Conclusions: High-intensity home-based RMT can improve pulmonary function and endurance and reduce breathing difficulties in patients with respiratory muscle weakness after injury. It is recommended for rehabilitation after spinal cord injury.

Objective To evaluate the relationships among spino-pelvic parameters, trunk balance and functional disability in patients with degenerative lumbar spondylolisthesis. Design Cross-sectional study. Subjects Forty-five patients with degenerative lumbar spondylolisthesis and 32 patients without degenerative lumbar spondylolisthesis. Methods Spino-pelvic parameters (pelvic incidence, pelvic tilt, sacral slope, lumbar lordosis) and pain severity were evaluated. Biodex balance tests (postural stability, limits of stability, modified clinical test of sensory interaction and balance, fall risk) and Quebec Back Pain Disability Scale (QBDS) scores were measured. Results Intergroup differences were found in age, low back pain, limits of stability, pelvic incidence, pelvic tilt and some subscales of QBDS. Correlations were found: (i) in the degenerative lumbar spondylolisthesis group: between pelvic incidence and sacral slope/pelvic tilt/lumbar lordosis/height/limits of stability; sacral slope and lumbar lordosis/height/limits of stability/modified clinical test of sensory interaction and balance (eyes closed on foam); lumbar lordosis and body mass index/QBDS/postural stability/modified clinical test of sensory interaction and balance (eyes open and eyes closed on foam); (ii) in the non-degenerative lumbar spondylolisthesis group: between pelvic incidence and pelvic tilt; pelvic tilt and sacral slope/lumbar lordosis; sacral slope and lumbar lordosis/fall risk. All spino-pelvic parameters in the degenerative lumbar spondylolisthesis group and pelvic tilt in the non-degenerative lumbar spondylolisthesis group correlated with QBDS. Conclusion Pelvic tilt was the major compensating factor in both groups (patients with and without degenerative lumbar spondylolisthesis). Sacral slope and lumbar lordosis contributed to partial compensation in the degenerative lumbar spondylolisthesis group. Lumbar lordosis correlated with body mass index. Sacral slope could be an indicator of fall risk in the non-degenerative lumbar spondylolisthesis group.

Objective To examine the efficacy of combined inspiratory and expiratory respiratory muscle training (RMT) with respect to the swallowing function, pulmonary function, functional performance, and dysarthria in patients with stroke. Design Prospective, randomized controlled trial. Setting Tertiary hospital. Participants The trial included 21 subjects (12 men, 9 women) aged 35 to 80 years presenting with 6 months history of unilateral stroke, respiratory muscle weakness (≥70% predicted maximal inspiratory pressure (MIP) and/or ≤70% maximal expiratory pressure (MEP)), dysphagia, or dysarthria. These subjects were randomly assigned to the control (n = 10, rehabilitation) and experimental (n = 11, rehabilitation with RMT) groups. Intervention Inspiratory RMT starting from 30% to 60% of MIP and expiratory RMT starting from 15% to 75% of MEP for 5 days/week for 6 weeks. Main outcome measures MIP, MEP, pulmonary function, peak cough flow, perception of dyspnea, Fatigue Assessment Scale, Modified Rankin Scale, Brunnstrom stage, Barthel index, Functional Oral Intake Scale (FOIS), and parameters of voice analysis. Results Significant differences were observed between both groups in terms of MIP, forced vital capacity (FVC), and forced expiratory volume per second (FEV1) of the percentage predicted. Significant difference was found with respect to the change in fatigue, shimmer percent, amplitude perturbation quotient, and voice turbulence index (VTI) according to the acoustic analysis in the RMT group. The FEV1/FVC ratio was negatively correlated with jitter percent, relative average perturbation, pitch perturbation quotient, and VTI; the maximum mid-expiratory flow (MMEF) and MMEF% were also negatively correlated with VTI. Significant differences among participants of the same group were observed while comparing the Brunnstrom stage before and after training of the affected limbs and the Barthel scale and FOIS scores in both the groups. Conclusions Altogether, 6-week combined inspiratory and expiratory RMT is feasible as adjuvant therapy for stroke patients to improve fatigue level, respiratory muscle strength, lung volume, respiratory flow, and dysarthria.Clinical trial registration number (Clinical Trial Identifier): NCT03491111.

We aimed to identify predictors for the changes of various developmental outcomes in preschool children with cerebral palsy (CP). Participants were 78 children (49 boys, 29 girls) with CP (mean age: 3 years, 8 months; SD: 1 year, 7 months; range: 1 year to 5 years, 6 months). We examined eight potential predictors: age, sex, CP subtype, Gross Motor Function Classification System (GMFCS) level, selective motor control, Modified Ashworth Scale, and the spinal alignment (SA) and range of motion subscales of the Spinal Alignment and Range of Motion Measure (SAROMM). Developmental outcomes for cognition, language, self-help, and social and motor functions were measured at baseline and a 6-month follow-up with the Comprehensive Developmental Inventory for Infants and Toddlers. Regression model showed GMFCS level was a negative predictor for change of language (adjusted r(2)=0.30, p

The aim of this study was to investigate the relationships between pulmonary function, respiratory muscle strength, perceived dyspnea, degree of fatigue, and activity of daily living with motor function and neurological status in stroke patients with stable congestive heart failure (CHF). This was a cohort study in a tertiary care medical center. Stroke patients with CHF and exertional dyspnea (New York Heart Association class I–III) were recruited. The baseline characteristics included duration of disease, Brunnstrom stage, spirometry, resting heart rate, resting oxyhemoglobin saturation (SpO2), maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), Borg scale, fatigue scale, and Barthel index. A total of 47 stroke patients (24 males, 23 females, mean age 65.9 ± 11.5 years) were included. The average Brunnstrom stages of affected limbs were 3.6 ± 1.3 over the proximal parts and 3.5 ± 1.4 over the distal parts of upper limbs, and 3.9 ± 0.9 over lower limbs. The average forced vital capacity (FVC) was 2.0 ± 0.8 L, with a predicted FVC% of 67.9 ± 18.8%, forced expiratory volume in the first second (FEV1) of 1.6 ± 0.7 L, predicted FEV1% of 70.6 ± 20.1%, FEV1/FVC of 84.2 ± 10.5%, and maximum mid-expiratory flow of 65.4 ± 29.5%. The average MIP and MEP were −52.9 ± 33.3 cmH2O and 60.8 ± 29.0 cmH2O, respectively. The Borg scale was 1.5 ± 0.8. MIP was negatively associated with the average Brunnstrom stage of the proximal (r = −0.318, P

Background Cardiopulmonary function can be adversely affected after a cerebrovascular accident in patients with congestive heart failure (CHF). The aim of this study was to investigate the efficacy and feasibility of inspiratory muscle training (IMT) for stroke patients with CHF. Methods A prospective randomized single-blind controlled trial was conducted in a single tertiary medical center in southern Taiwan between May 2011 and July 2015. Forty-one patients were enrolled, of whom 21 completed the study (IMT group n = 11 and control group n = 10). Both groups participated in a conventional stroke rehabilitation program. Patients in the IMT group received an additional IMT program beginning with an intensity of 30% maximal inspiratory pressure (MIP), then increased by 2cmH2O each week for 30 minutes daily for at least 5 days a week for 10 weeks. MIP, maximal expiratory pressure, spirometry, resting oxyhemoglobin saturation, modified Borg Scale, Fatigue Assessment Scale, and Barthel Index were assessed in each patient. Results There were significant differences from baseline in MIP (P = 0.008), percent predicted forced vital capacity (P = 0.033), forced expiratory volume in 1 second (FEV1) (P = 0.008), percent predicted FEV1 (P = 0.008), and Barthel Index (P = 0.012) in the IMT group, and Barthel Index (P = 0.027) in the control group. There were significant differences between groups in MIP (20.91 ± 19.73 vs −9.00 ± 26.01, adjusted P value = 0.023) and Barthel Index (24.55 ± 22.30 vs 7.50 ± 8.25, adjusted P value = 0.044). Conclusion The 10-week IMT was feasible and effective in improving inspiratory force and activities of daily living for the stroke patients with CHF.

This study is the first well-designed randomized controlled trial to assess the effects of a novel home-based virtual cycling training (hVCT) program for improving muscle strength in children with spastic cerebral palsy (CP). Twenty-eight ambulatory children with spastic CP aged 6-12 years were randomly assigned to an hVCT group (n=13) or a control group (n=15). Outcome measures, including gross motor function of the Bruininks-Oseretsky Test of Motor Proficiency (BOTMP) and muscle strength (isokinetic torque of knee extensor and flexor muscle), were administered before and immediately after the 12-week intervention. Analysis of covariance (ANCOVA) at post-treatment showed that, compared to the control group, the hVCT group had significantly higher isokinetic torque in the knee extensor and flexor muscles at 60°/s and 120°/s angular velocities (p

Objective To assess the changes in static and dynamic balance and movement strategies in patients with severe osteoporotic vertebral compression fracture while wearing and not wearing the Knight-Taylor (K-T) spinal brace. Subjects 47 patients with severe osteoporotic vertebral compression fracture, which was confirmed on radiographs and with bone density measurements obtained by dual energy X-ray absorption. Intervention Patients were randomly subjected to computerized dynamic posturography, which contained sensory organization tests, motor control balance test at 75% limit of stability (LOS) in 8 movement directions, and left/right rhythmic weight shift test (L/R RWS), while wearing and not wearing the K-T spinal brace, respectively. Results Patients wearing the spinal brace had significantly increased average stability, significantly increased average maximal stability under the swayed vision with fixed support surface condition and under the eye open with swayed support surface condition, significantly increased ankle strategy and decreased average velocity of COG target sway under the eye open with swayed support surface condition, significantly reduced the frequency of falls under the eye closed with swayed support surface condition and swayed vision with swayed support surface condition, and significantly decreased in the percentage of directional control with no difference of reaction time in the LOS test, and an increase in the on-axis velocity in the L/R RWS test. Conclusions The K-T spinal brace efficiently enables the subjects to maintain static and dynamic motor balance. Its use decreases the fall frequency but limits the directional control in severe osteoporotic patients with vertebral compression fracture.

Arch Phys Med Rehabil 2001;82:335-41. Objective: To identify what influence the various features of spinal deformity have on pulmonary function in persons with idiopathic and the postpoliomyelitic scoliosis. Design: Prospective, cohort, observational study with clinical and radiologic evaluations. Setting: Hospital-based rehabilitation units. Patients: Forty-four patients with idiopathic scoliotis and 16 with postpoliomyelitic scoliotis. Each group was divided into subgroups: normal and abnormal pulmonary function. Intervention: Clinical and radiologic evaluation of spinal deformity, full pulmonary functional test and respiratory muscle strength were performed. Presence of dyspnea on exertion and low back pain (LBP) was recorded. Main Outcome Measures: Pulmonary function: spirometry, lung volume test, and diffusing capacity. Respiratory muscle strength: maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP). Presence of dyspnea on exertion (DOE), and LBP were also recorded. Characteristics of spinal deformity: direction of convexity, uppermost vertebra, number of involved vertebrae, Cobb angle, the apical vertebra, degree of rotation at the apical vertebra, type of scoliotic curve, and presence of balanced spine and pelvic obliquity. Chi-square analyses and Mann-Whitney U test for between-groups comparisons. Spearman's rho correlation coefficient to determine the existence and magnitude of a relationship. Results: We found significant differences between the idiopathic and postpoliomyelitis groups in the degree of rotation at the apical vertebra, MIP, average percentage of predicted vital capacity, residual volume/total lung capacity, presence of double or triple curves, pelvic obliquity, and DOE. Between the idiopathic scoliotis subgroups we found significant differences in the uppermost vertebra and number of vertebrae in the scoliotic curve. Between the subgroups of the postpoliomyelitis group were significant differences in the location of the apical vertebra and the uppermost vertebral body of scoliotic curve. In the idiopathic group, pulmonary function was mostly related to scoliotic angle, number of vertebrae in the scoliotic curve, location of the uppermost vertebra, and the patients' age; MIP and MEP were negatively related to the scoliotic angle and degree of rotation of apical vertebra. In the postpoliomyelitis group, pulmonary function was mostly related to scoliotic angle, kyphotic angle, location of the uppermost vertebra of the scoliotic curve, and age. Conclusion: No single factor can predict the severity of impairment in scoliotic patients' pulmonary function. In both groups, severity of pulmonary impairment was related to the combined features of the spinal deformity. However, uppermost vertebra, scoliotic angle, and patient's age may play important roles influencing pulmonary function in both groups.

To assess the efficacy of electrical acupuncture in the rehabilitation of patients with hemiplegia in stroke, we randomized 128 patients within 2 wk of stroke onset to receive either comprehensive rehabilitation plus electrical acupuncture (n = 59) or comprehensive rehabilitation only (n = 59). Electrical acupuncture was administered by electrical stimulation of acupuncture points through adhesive surface electrodes five times per week. Neurological status (Brunnstrom's stage) and the Chinese version of the Functional Independence Measure were assessed before treatment and at discharge. Patients treated with electrical acupuncture had a shorter duration of hospital stay for rehabilitation and better neurological and functional outcomes than the control group had, with a significant difference in scores for self-care and locomotion (P = 0.02). This result did not postulate the previous study that acupuncture therapy for stroke patients should depend on needle manual and "de qi" response. We suggest that electrical acupuncture through adhesive surface electrodes in conjunction with current optimal rehabilitation programs is a convenient and effective therapy for stroke patients.

A total of 61 traumatic cervical cord-injured patients were included in this study. Needle electromyography and nerve conduction study were performed at 6 to 24 weeks postinjury. Correlation between the presence of spontaneous electromyographic potentials and the presence of dysesthetic pain, as well as other clinical characteristics including age, gender, level of injury, severity of injury, spasticity, duration of injury, and performance of spinal surgery was statistically analyzed. Of the 31 patients who had spontaneous electromyographic potentials in their hands, 27 (87%) had dysesthetic pain in their limbs. Only 9 (30%) of the other 30 patients without spontaneous potentials developed dysesthetic pain. A significant correlation (P < 0.001) between the presence of spontaneous electromyographic potential and dysesthetic pain was found. The presence of spontaneous electromyographic potentials was also significantly (P < 0.05) correlated with severity of injury but not with age, gender, injury level, duration of injury, operation, and spasticity. In conclusion, the presence of spontaneous electromyographic potentials in cervical cord-injured patients was significantly related to the presence of dysesthetic pain. They occurred more often in patients with more severe injury.

Objective Patients with osteoporotic vertebral compression fracture (OVCF) have postural changes and increased risk of falling. The aim of this study is to compare balance characteristics between patients with OVCF and healthy control subjects. Methods Patients with severe OVCF and control subjects underwent computerised dynamic posturography (CDP) in this case-control study. Results Forty-seven OVCF patients and 45 controls were recruited. Compared with the control group, the OVCF group had significantly decreased average stability; maximal stability under the `eye open with swayed support surface' (CDP subtest 4) and 'eye closed with swayed support surface' conditions (subtest 5); and decreased ankle strategy during subtests 4 and 5 and under the `swayed vision with swayed support surface' condition (subtest 6). The OVCF group fell more frequently during subtests 5 and 6 and had longer overall reaction time and longer reaction time when moving backward during the directional control test. Conclusion OVCF patients had poorer static and dynamic balance performance compared with normal control. They had decreased postural stability and ankle strategy with increased fall frequency on a swayed surface; they also had longer reaction times overall and in the backward direction. Therefore, we suggest balance rehabilitation for patients with OVCF to prevent fall.

Background Hemiplegic shoulder pain (HSP) is one of the most common comorbidities in stroke patients with flaccid shoulders. The pain limits functional motor recovery and affects the activities of daily living after acute stroke. This study investigated the effects of hyaluronic acid (HA) injection on pain reduction and motor function in subacute stroke patients with HSP and injury. Methods A randomized, double-blinded controlled trial was conducted in a medical center. Twenty-six subacute stroke patients were enrolled and randomly divided into 2 groups: the experimental group (n = 16) received ultrasound-guided, subacromial HA injections once per week for 3 weeks and conventional rehabilitation, whereas the control group (n = 10) received 0.9% sodium chloride injections once per week for 3 weeks and conventional rehabilitation. Shoulder pain and motor function were evaluated before and after the intervention using the visual analog scale (VAS) and the Fugl-Meyer assessment for the upper extremity (FMA-UE), respectively. Results In the experimental group, significant differences were found in VAS (P = 0.003), shoulder flexion (P = 0.03) and abduction (P = 0.02), and FMA-UE (P = 0.003) after treatment. In the control group, there were significant differences in VAS (P = 0.007), shoulder flexion (P = 0.035), and FMA-UE (P = 0.042) after treatment. The comparison of the changes in the parameters between the experimental and control groups, after each intervention, revealed a significant difference in VAS (P = 0.001). Conclusion Subacromial HA injection could result in positive effects on shoulder pain and shoulder abduction in subacute stroke patients with HSP and injury.

Objectives: This study is designed to investigate the degree of correlation of hemiplegic shoulder pain to some clinical parameters including electrodiagnostic testing. Methods: Fifty post-stroke patients were divided into 3 groups: Group A patients had spontaneous hemiplegic shoulder pain, Group B patients had shoulder pain only during movement, and Group C patients had no shoulder pain. The correlational relationships between shoulder pain in the hemiplegic side and some clinical parameters including age, sex, side affected, duration of stroke, motor function, sensory impairment, spasticity, shoulder subluxation, shoulder contracture, peripheral nerve conduction, and the presence of spontaneous electromyographic [EMG] activity was analyzed statistically. Results: Data analysis revealed no significant correlation between the hemiplegic shoulder pain and age, sex, side affected, or duration of stroke. However, the presence of shoulder subluxation or limitation of passive shoulder range of motion [ROM] sho...

Objective: To investigate the correlation between hemiplegic shoulder pain factors during the acute and chronic stages of stroke recovery. Design: A prospective longitudinal study. Subjects: Seventy-six stroke patients with hemiplegic shoulders. Methods: Hemiplegic shoulder pain and clinical, physical, and sonography results were recorded at admission and during both acute (before discharge) and chronic stages (6 months after discharge). Results: During the acute stage, hemiplegic shoulder pain correlated significantly with shoulder motor function level and range of motion limitations. During the chronic stage, hemiplegic shoulder pain correlated significantly with shoulder motor function level, range of motion limitations, spasticity and abnormal sonographic findings. Higher incidence (p = 0.014) of hemiplegic shoulder pain and pain scores (p < 0.01) were noted and abnormal sonographic findings of the biceps tendon long head (p = 0.01) and subscapularis tendon (p = 0.01) were higher during the chronic stage. Effusion, tenosynovitis or tendinopathy of the biceps tendon long head, and supraspinatus tendinopathy were notable during both stages. Conclusion: Hemiplegic shoulder pain was correlated with lower motor function level and shoulder range of motion limitation in both stages. Shoulder spasticity and abnormal sonographic findings were correlated with hemiplegic shoulder pain during the chronic stage.

Objective: To investigate the efficacy and feasibility of home-based inspiratory muscle training in patients with bronchiectasis.Design: A prospective, single-blind, randomized, controlled study.Setting: Outpatient clinic of a tertiary care medical centre.Methods: Twenty-six patients with bronchiectasis were randomly divided into inspiratory muscle training and control groups. In the inspiratory muscle training group (n = 13), the training programme started with an intensity of 30% maximal inspiratory pressure (MIP), which was increased by 2 cmH2O each week, for 30 minutes daily, 5 days a week for eight weeks. The control group (n = 13) did not receive inspiratory muscle training. Main outcome measures included spirometry, resting oxyhaemoglobin saturation by pulse oximetry (SpO2), lowest SpO2 and Borg Scale during 6-minute walking tests, 6-minute walking distance (6MWD), 6-minute walking work (6Mwork), MIP, maximal expiratory pressure (MEP) and St George’s Respiratory Questionnaire.Results: There were significant differences in change from baseline in 6MWD (411.9 (133.5) vs. 473.2 (117.2) m, P = 0.021), 6Mwork (21 051.0 (8286.7) vs. 23 915.5 (8343.0) kg-m, P = 0.022), MIP (60.8 (21.8) vs. 84.6 (29.0) cmH2O, P = 0.004), and MEP (72.3 (31.1) vs. 104.2 (35.7) cmH2O, P = 0.004) in the inspiratory muscle training group. Significant improvements in both MIP (23.8 (25.3) vs. 2.3 (16.4) cmH2O, adjusted P-value = 0.005) and MEP (31.9 (30.8) vs. 11.5 (20.8) cmH2O, adjusted P-value = 0.038) levels after adjusting for age by linear regression analysis were observed between groups.Conclusions: An eight-week home-based inspiratory muscle training is feasible and effective in improving both inspiratory and expiratory muscle strength, but has no effect on respiratory function and quality of life in patients with bronchiectasis.

Recognizing special health care needs (SHCN) is obligatory for children with developmental delay (DD). The purpose of this study was to compare hospital-based and community-based services for the SHCN of children with DD.We collected 114 children with DD. An expert-designed questionnaire was used to measure the SHCN of children in either hospital-based or community-based services. The questionnaire included the children's characteristics, family ecology and SHCN, which encompassed four categories, team assessment and counseling, rehabilitation, complementary and alternative treatment, and home care. We compared the differences and needs between the two health care services.More children with DD in hospital-based services had disabled certificates, catastrophic illness certificates and multiple caregivers than community based services. More children with DD in community-based services had severe-disabled certificates than those in hospital-based services (p0.001). Children in hospital-based services had more SHCN for some items of team assessment and counseling, rehabilitation, and complementary and alternative treatment than those in community-based services (p0.05). The need for home care was not significantly different between the two services except for nutrition counseling (p = 0.048).SHCN in multiple aspects imply the necessity for team assessment and counseling, rehabilitation, complementary and alternative treatments and nutrition counseling in approaching children with DD in hospital-based services.

Body sway increases with age. The purpose of this study was to obtain baseline data and the characteristics of balance performance in different age groups for balance strategy management.Healthy individuals (n = 107) were divided into young, middle-aged, and elderly groups, and assessed by computerized dynamic posturography (CDP) on a Smart Balance Master. The 6 subtests in the sensory organization tests (SOT) for the CDP were as follows: subtest 1, eyes open, fixed support platform; subtest 2, eyes closed, fixed platform; subtest 3, eyes open, fixed platform; subtest 4, eyes open, swaying platform; subtest 5, eyes closed, swaying platform; subtest 6, swaying visual surround, swaying platform. Motor balance control tests included the limit of stability (LOS) test at 75% of LOS in 8 directions and the left/right and forward/backward rhythmic weight shift (RWS) test.In the SOT, the elderly group demonstrated significantly lower average stability and maximal stability scores in subtests 4-6. This group also demonstrated a relatively lower average percentage of ankle strategy in subtests 4-6. In the motor control tests, the elderly group demonstrated a significantly higher overall reactive time and lower overall directional control in the LOS test, lower on-axis velocity during the forward/backward and left/right motor control test and a lower average percentage of forward/backward directional control in the RWS test.The elderly had a higher degree of postural imbalance and used hip strategy to a greater extent to maintain their balance, especially when standing on a swaying support surface in the absence of visual surround or with conflicted visual surround. The elderly required a longer reaction time and demonstrated lower directional control in balance performance.

Bilateral diaphragmatic paralysis (BDP) manifests as respiratory muscle weakness, and its association with critical illness polyneuropathy (CIP) was rarely reported. Here, we present a patient with BDP related to CIP, who successfully avoided tracheostomy after diagnosis and management.A 71-year-old male presented with acute respiratory failure after sepsis adequately treated. Repeated intubation occurred because of carbon dioxide retention after each extubation. After eliminating possible factors, septic shock-induced respiratory muscle weakness was suspected. Physical examination, a nerve conduction study, and chest ultrasound confirmed our impression.Pulmonary rehabilitation and reconditioning exercises were arranged, and the patient was discharged with a diagnosis of BDP.The diagnosis of BDP is usually delayed, and there are only sporadic reports on its association with polyneuropathy, especially in patients with preserved limb muscle function. Therefore, when physicians encounter patients that are difficult to wean from mechanical ventilation, CIP associated with BDP should be considered in the differential diagnosis.

Objective: To determine the role of symmetrical body-weight distribution training in preventing falls among patients with hemiplegic stroke. Design: A prospective study using a standing biofeedback trainer. Setting: Hospital-based rehabilitation units. Patients: Fifty-four patients with hemiplegic stroke (30 in the training group, 24 in the control group). Interventions: Conventional stroke rehabilitation program, plus symmetrical standing training and repetitive sit-to-stand training, with a standing biofeedback trainer. Training effect was evaluated by assessing the sit-to-stand performance and comparing the occurrence of falls in the 2 groups at a 6-month follow-up. Main Outcome Measures: Occurrence of falls, sit-to-stand performance, including body-weight distribution, rate of rise in force, and sway in center of pressure (COP). Results: Significant improvement in sit-to-stand performance was found in patients in the training group. Body weight was distributed more symmetrically in both legs, with less mediolateral sway in the COP when rising and sitting down. The mean difference in body-weight distribution between the left and right legs while subjects were rising from a chair significantly decreased, from 49.5% ± 18.9% to 38.6% ± 15.8% of body weight (BW) ( p p p Conclusions: Symmetrical body-weight distribution training may improve sit-to-stand performance and, consequently, decrease the number of falls by stroke patients. © 2001 by the American Congress of Rehabilitation Medicine and the American Academy of Physical Medicine and Rehabilitation

Liaw M-Y, Lin M-C, Cheng P-T, Wong M-KA, Tang F-T. Resistive inspiratory muscle training: its effectiveness in patients with acute complete cervical cord injury. Arch Phys Med Rehabil 2000;81:752-6. Objective: To evaluate if resistive inspiratory muscle training (RIMT) can improve lung function in patients with complete tetraplegia within half a year after trauma. Design: A prospective study. The experimental patients received training with a Diemolding Healthcare Division inspiratory muscle trainer for 15 to 20 minutes per session, twice per day, 7 days a week for 6 weeks. Setting: Hospital-based rehabilitation units. Patients: Twenty patients who were in their first 6 months of complete cervical cord injury were randomly enrolled into RIMT (10 patients) and control (10 patients) groups. Main Outcome Measure: Spirometry, lung volume test, maximal inspiratory pressure, maximal expiratory pressure, and modified Borg scale measurements at rest were performed before training and at the end of 6 weeks of training. Results: Most of the pulmonary parameters showed statistically significant improvements within the RIMT and control groups, but the improvements were greater in the RIMT group. In addition, the improvements in total lung capacity, total lung capacity predicted percentage, vital capacity, minute ventilation, forced expiratory volume in 1 second predicted percentage, and the resting Borg scale in the RIMT group showed significantly greater improvement. Conclusion: RIMT can improve ventilatory function, respiratory endurance, and the perceived difficulty of breathing in patients with complete cervical spinal cord injury within half a year after trauma. © 2000 by the American Congress of Rehabilitation Medicine and the American Academy of Physical Medicine and Rehabilitation

To use kinetic assessment of the sit-to-stand movement as a means of sorting out those stroke patients at risk for falling.A retrospective study, using a force platform to assess sit-to-stand performance and to determine its correlation with falls in stroke patients.Hospital-based rehabilitation units.Thirty-three stroke patients (18 fallers, 15 nonfallers) and 25 age-matched healthy subjects were included in this study. Subjects sat in an adjustable chair with their feet on two force plates and performed the standing up/sitting down movement at a self-paced, comfortable speed.The rate of rise in force (dF/dT) was significantly lower in stroke fallers than in stroke nonfallers and healthy subjects (23.78+/-17.38, 55.23+/-31.24, and 85.96+/-42.4 percent body weight per second, respectively [p.005]). The center of pressure sway in mediolateral direction during rising/ sitting down was much greater in stroke fallers than in stroke nonfallers or healthy subjects (p.05). Body weight distribution was asymmetric on the feet of stroke patients, with much more body weight on their sound side.The significantly lower rate of rise in force and greater postural sway while rising/sitting down may be useful in identifying stroke patients who are at risk for falling.
