This study aimed to determine whether filtering out walking-related actigraphy data improves the reliability and accuracy of real-world upper extremity activity assessment in children with unilateral cerebral palsy. Twenty-two children aged 4–12 years diagnosed with unilateral cerebral palsy were included in this study, which was drawn from a two-phase randomized controlled trial conducted from July 2021 to December 2022. Data were collected from a tertiary hospital in Seoul, Republic of Korea. Participants were monitored using tri-axial accelerometers on both wrists across three time points (namely, T0, T1, and T2) over 3 days; interventions were used between each time point. Concurrently, an in-laboratory study focusing on walking and bimanual tasks was conducted with four participants. Data filtration resulted in a reduction of 8.20% in total data entry. With respect to reliability assessment, the intra-class correlation coefficients indicated enhanced consistency after filtration, with increased values for both the affected and less-affected sides. Before filtration, the magnitude counts for both sides showed varying tendencies, depending on the time points; however, they presented a consistent and stable trend after filtration. The findings of this research underscore the importance of accurately interpreting actigraphy measurements in children with unilateral cerebral palsy for targeted upper limb intervention by filtering walking-induced data.

Background: Accurate assessment of physical activity and motor function in children with cerebral palsy is crucial for determining the effectiveness of interventions. This study aimed to investigate the correlation between real-world activity monitoring outcomes and in-laboratory standardized hand function assessments in children with unilateral cerebral palsy. Methods: Actigraphy data were collected over 3 days from children aged 4–12 years with unilateral cerebral palsy before in-laboratory assessments. To tackle the high dimensionality and collinearity of actigraphy variables, we first applied hierarchical clustering using the Pearson correlation coefficient as the distance metric and then performed a principal component analysis (PCA) to reduce the dimensionality of our data. Results: Both hierarchical clustering and PCAs revealed a consistent pattern in which magnitude ratio variables (ln[affected side magnitude/less-affected side magnitude]) were more strongly associated with standardized assessments of hand function than with activity time and distance domain variables. Hierarchical clustering analysis identified two distinct clusters of actigraphy variables, with the second cluster primarily consisting of magnitude ratio variables that exhibited the strongest correlation with Melbourne Assessment 2, Pediatric Motor Activity Log, Assisting Hand Assessment, and Manual Ability Classification System level. Principal component 2, primarily representing the magnitude ratio domain, was positively associated with a meaningful portion of subcategories of standardized measures, whereas principal component 1, representing the activity time and distance component, showed limited associations. Conclusions: The magnitude ratio of actigraphy can provide additional objective information that complements in-laboratory hand function assessment outcomes in future studies of children with unilateral cerebral palsy.

This study aimed to elucidate the role of tri-axial accelerometers in assessing therapeutic interventions, specifically constraint-induced movement therapy (CIMT), in children with unilateral cerebral palsy (UCP). The primary focus was understanding the correlation between the actigraphy metrics recorded during CIMT sessions and the resultant therapeutic outcomes. Children with UCP, aged between 4 and 12 years, participated in this study from July 2021 to December 2022. In conjunction with in-clinic sessions, during which participants wore tri-axial accelerometers on both limbs, we analyzed actigraphy data over three days of routine activities pre- and post-CIMT. While not all metrics derived from the accelerometers indicated significant improvements post-intervention, there was a clear trend towards a more balanced usage of both limbs, particularly evident in Axis 3, associated with vertical movement (p = 0.017). Additionally, a discernible correlation was observed between changes in the magnitude ratio derived from actigraphy data during CIMT (Δweek3–week1) and variations in traditional assessments pre- and post-intervention (ΔT0–T1), specifically the Assisting Hand Assessment grasp and release. Using tri-axial accelerometers has helped clarify the potential impacts of CIMT on children with UCP. The preliminary results suggest a possible link between actigraphy metrics taken during CIMT and the subsequent therapeutic outcomes determined by standardized tests. [ABSTRACT FROM AUTHOR]

Maintaining physical activity is important for children with cerebral palsy (CP). This study examined whether age predicted habitual physical activity (HPA) or cardiorespiratory fitness (CRF) in school-aged children with CP and clarified the relationship between HPA and CRF. We utilized cross-sectional data from 39 children with CP (18 girls and 21 boys; mean age 7.44 years; mean body weight 24.76 kg; mean body mass index 15.97 kg/m2; hemiplegic or diplegic CP). The participants wore an accelerometer (ActiGraph) for five days to measure HPA, physical activity energy expenditure (kcal/kg/d), sedentary physical activity (%SPA), light physical activity, moderate-to-vigorous physical activity (%MVPA), and activity counts (counts/min). Participants underwent cardiopulmonary exercise tests on a treadmill using a modified Naughton protocol. Linear regression and correlation analyses were performed. p-value (two-tailed) < 0.05 was considered statistically significant. Age was positively associated with SPA. MVPA negatively correlated with resting heart rate (HR), and activity counts were negatively correlated with resting HR. In conclusion, our study found strong evidence of a negative association between HPA and age in school-aged children with CP. It highlights the importance of creating and improving recreational opportunities that promote physical activity in all children with CP, regardless of whether they are considered therapeutic.

The Canadian Occupational Performance Measure (COPM) is a client-centered outcome measure that facilitates the prioritization of individualized interventions. Given the rising emphasis on individualized intervention in pediatric intensive care units (PICUs), this cross-sectional study aimed to explore caregivers' perspectives on their children's functional goals within PICUs. From 1 September 2020 to 26 June 2022, caregivers of 41 children aged 1–18 years completed the COPM within 48 h of PICU admission. The study also explored the clinical variables predicting a high number of occupational performance goals (≥4/5). Out of 190 goals proposed by caregivers, 87 (45.8%) pertained to occupational performance, while 103 (54.2%) were related to personal factors. Among the occupational performance goals, the majority were associated with functional mobility (55; 28.9%), followed by personal care (29; 15.2%) and quiet recreation (3; 1.6%). Among personal goals, physiological factors (68; 35.8%) were most common, followed by physical factors (35; 18.4%). We found caregiver anxiety, measured by the State-Trait Anxiety Inventory-State, to be a significant predictor of the number of occupational performance goals. These findings underscore the importance of caregiver psychological assessment in the PICU to facilitate personalized goal setting and improve rehabilitation outcomes. [ABSTRACT FROM AUTHOR]

Background: Participation in physical activities is positively associated with better quality of life in children with cerebral palsy (CP). The objective of this study was to elucidate the relationship between the intensity of habitual physical activity (HPA) measured with an accelerometer and health-related quality of life (HRQOL) in school-age children with CP. Method: A secondary analysis of the cross-sectional data of 46 ambulatory children with CP was conducted. The participants wore an accelerometer for seven days to measure HPA: activity counts (counts/min) and physical activity energy expenditure (PAEE, kcal/kg/day), as well as %moderate-to-vigorous intensity physical activity (%MVPA), %light intensity physical activity (%LPA), and %sedentary physical activity (%SPA) were measured. Pediatric Quality of Life Inventory (PedsQL) 4.0 Generic Core Scales and Child Health Questionnaire Parent Form 50 Questions (CHQ-PF50) were used to measure HRQOL. A Pearson analysis and a hierarchical regression analysis were performed. Results: PAEE significantly predicted the results of the PedsQL(child) physical domain (β = 0.579, p = 0.030), PedsQL(child) emotional domain (β = 0.570, p = 0.037), PedsQL(child) social domain (β = 0.527, p = 0.043), and PedsQL(child) total (β = 0.626, p = 0.017). However, other HPA parameters could not predict any other HRQOL. Conclusions: PAEE could be used as a biomarker in studies on HRQOL and HPA in ambulatory school-age children with CP.

The membrane-bound O-acyltransferase domain-containing 7 (MBOAT7) gene is associated with intellectual disability, early onset seizures, and autism spectrum disorders. This study aimed to determine the pathogenetic mechanism of the MBOAT7 missense variant via molecular modeling. Three patients from a consanguineous family were found to have a homozygous c.757G>A (p.Glu253Lys) variant of MBOAT7. The patients showed prominent dysfunction in gait, swallowing, vocalization, and fine motor function and had intellectual disabilities. Brain magnetic resonance imaging showed signal changes in the bilateral globus pallidi and cerebellar dentate nucleus, which differed with age. In the molecular model of human MBOAT7, Glu253 in the wild-type protein is located close to the backbone carbonyl oxygens in the loop near the helix, suggesting that the ionic interaction could contribute to the conformational stability of the funnel. Molecular modeling showed that Lys253 in the mutant protein was expected to alter the surface charge distribution, thereby potentially affecting substrate specificity. Changes in conformational stability and substrate specificity through varied ionic interactions are the suggested pathophysiological mechanisms of the MBOAT7 variant found in patients with intellectual disabilities.

Background: Attention problems and decreased quality of life are frequently accompanied in Cerebral Palsy (CP), which can negatively affect rehabilitation of physical disability. However, the majority of affected children remain untreated in the aspects of attention or psychosocial factors. Equine-Assisted Activities and Therapies (EAAT) use horse as a therapeutic modality including grooming as well as mounted riding activities in which patients exercise and experience mounted stimulation. It is known to help improve attention in children with ADHD, so that it can be an exercise therapy that is expected to improvement of attention as well as rehabilitating effects in CP patients. EAA may be a promising strategy to address the unmet need for CP patients. This study aims to investigate the efficacy of EAA for children with CP, those with both CP and ADHD and confirm the comorbidity between CP and ADHD.Methods: Forty-six children with cerebral palsy participated in this study. For the exercise group, they participated in a 40-min session twice a week for a 16-week period, while the control group engaged in daily life without any special treatments. Each children individually were assessed on attention and psychological wellbeing at baseline and post-treatment. Comorbidity were identified based on the Diagnostic and Statistical Manual of Mental Disorder 5th edition (DSM-5) and confirmed by Korean Kiddie-Schedule for Affective Disorders and Schizophrenia Present and Lifetime Version (K-SADS-PL).Results: Perseveration rated using the Conner's Performance Test (CPT) showed a significant decrease only in the exercise group (p < .024). However, no significant improvement in children's quality of life was observed after EAA program compared with control group. Among the total participants, fifteen children (31.91%) were diagnosed with ADHD. When conducting an additional analysis with the subsample of CP patients diagnosed with ADHD, the d', commission error and perseveration showed a significant decrease only in the exercise group. Children with CP and ADHD reported an improvement in quality of life both in exercise and control group, but only in the exercise group social functioning exhibited a significant difference.Conclusion: The positive effects of the EAA on attention and quality of life were confirmed. Children with CP in the exercise group were more capable to sustain their attention longer. Those with CP and ADHD showed an increase in attention and perceived to have better social skills after receiving 16 weeks of EAA compared to those in the control group. Considering high comorbidity of CP and ADHD, it seems that the EAA program could be the better alternative treatment for CP with attentional problem. The results of this study will contribute to growing evidence for the efficacy of EAA in children especially with CP and ADHD.Trial Registration: This trial was registered on ClinicalTrials.gov ( NCT03870893 ).

Objective: Children with cerebral palsy (CP) have an impaired cardiac autonomic function. Attenuated heart rate recovery (HRR), which is a valuable prognostic parameter for autonomic nervous system, is known to be associated with an increased risk of cardiovascular events and all-cause mortality. However, only few studies have observed the effects of exercise on the cardiac autonomic function in children with CP. The purpose of this pilot study was to examine the effects of equine-assisted activity (EAA) program on cardiac autonomic function in children with CP. Design: A single-blinded, parallel, two-arm pilot trial with 1:1 randomization to the EAA or control group. Setting: A tertiary university hospital and a local arena. Subjects: Twenty-six children with CP (Gross Motor Function Classification System Levels I–II). Intervention: Each lesson of the EAA program for the EAA group was conducted for 40 min twice a week, and the whole program duration was 16 weeks (a total of 32 sessions). Outcome measures: A graded exercise test was performed to measure the resting heart rate (RHR), HRR, and peak oxygen uptake (VO2peak) on both groups before and after the 16-week period. Results: The autonomic nervous function measured by the response of HRR improved at 1 min (p < 0.009), 3 min (p < 0.001), and 5 min (p < 0.004) only in the EAA group. RHR significantly improved in the EAA group (p < 0.013), whereas the VO2peak did not significantly differ between the two groups. Conclusion: The HRR and RHR of the children with CP improved after completing the 16-week EAA program. The results demonstrated that the program had a positive effect on the improvement of cardiac autonomic function in these patients.

Objective To determine whether modified constraint-induced movement therapy (mCIMT) with continuous restraint is feasible and effective in improving the use of the paretic arm in the real world among infants and toddlers with unilateral cerebral palsy (CP). Design Single-blind randomized controlled trial. Setting Tertiary hospital. Participants Children aged 7 to 36 months with unilateral CP (N = 24; 16 boys, 8 girls). Intervention The experimental group received 2-hour clinic-based mCIMT sessions (5 days per week for 3 weeks), and a continuous restraint was applied. Main Outcome Measures Standardized assessments were conducted. Peabody Developmental Motor Scales-2 (PDMS-2), Gross Motor Function Measure-66, Pediatric Motor Activity Log (PMAL), and Pediatric Evaluation of Disability Inventory were measured pre- and postintervention. Children who agreed to participate in the accelerometer study additionally wore accelerometers on both their wrists for 3 days before and after the intervention. Results The mCIMT group exhibited greater improvement in PMAL-how often (p = 0.048; ηp2 = 0.173), PMAL-how well (p = 0.008; ηp2 = 0.289), and PDMS-2 visual motor integration (p = 0.014; ηp2 = 0.256) posttreatment than the control group. The percentage of time in moderate-to-vigorous physical activity (z = –2.24; p = 0.03) and vector magnitude average counts (z = –2.52; p = 0.01) significantly increased in children in who wore accelerometers (N = 8) after the 3-week mCIMT protocol. Conclusion mCIMT with continuous restraint applied to infants and toddlers with unilateral CP appeared to have a positive effect on paretic hand use in the real world.

Aim: To design and manufacture a patient-specific assistive device optimized for patient function after estimating the disability status of a patient with brain injury through 3D printing technique Materials and methods: The left hand of a man with right-side hemiparesis was scanned with a three-dimensional scanner, and the left-hand image was flipped over to the right side to design the orthosis. To change devices easily, a connector was designed to connect the devices and was easily detachable with the orthosis by using the magnetics. To enable the writing, a round-shaped ring was attached to the orthosis to fix a pen. The Jebsen–Taylor Hand Function Test (JHFT) and Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST) were evaluated one month after the application. Results: The JHFT score improved after application 3D printed devices. In most QUEST items, 3D printed devices showed better results than ready-made assistive devices. The typing speed became faster in 3D printed devices than in ready-made assistive devices. The patient was satisfied with the orthosis in writing a pen, eating food and typing keyboard because of its fitness to his hand and easy-to-use. Conclusion: We designed and manufactured a patient-specific assistive device optimized for patient function after estimating the disability status of a patient with brain injury through 3D printing techniques. We hope to provide low-cost, customized devices to disabled patients through 3D printing techniques.

Background:: Three-dimensional printer technology can produce the personalized orthosis in various forms.Objective:: To develop a personalized wrist orthosis using a three-dimensional scanner and three-dimensional printer for patients with wrist pain.Study Design:: A preliminary, prospective, randomized, open-label study.Methods:: A total of 22 patients with wrist pain were randomly assigned to the control and experimental groups. The control group wore a cock-up orthosis and the experimental group wore a three-dimensional-printed wrist orthosis for 1 week. The Patient-Rated Wrist Evaluation, Jebsen Hand Function Test, and Orthotics and Prosthetics Users' Survey were checked before and 1 week after the application.Results:: The Patient-Rated Wrist Evaluation showed significant pain relief in both groups. Two items of the 28 Orthotics and Prosthetics Users' Survey questions, "Put toothpaste on brush and brush teeth" and "Dial a touch tone phone," showed high satisfaction scores, with statistically significant difference in the experimental group ( p = 0.036 and 0.004).Conclusion:: The three-dimensional-printed wrist orthosis was superior to the cock-up orthosis for two items of the Orthotics and Prosthetics Users' Survey. Wrist pain was reduced in the group wearing the three-dimensional-printed wrist orthosis as well as the group wearing the cock-up orthosis, so the three-dimensional-printed wrist orthosis could possibly play the same role as the cock-up orthosis.Clinical Relevance: A three-dimensional-printed wrist orthosis can be a substitute for a conventional ready-made wrist orthosis for patients with wrist pain with more satisfaction.

Objectives: Pharmacotherapy among children with attention-deficit/hyperactivity disorder (ADHD) is effective, but many patients suffer from secondary psychiatric problems even after improvement of ADHD core symptoms. Hippotherapy have been used as adjunct treatment options for physical and psychosocial rehabilitation as well as to ameliorate core symptoms. The aim of this study was to investigate the effects of Hippotherapy versus pharmacotherapy for children with ADHD. Design: Thirty-four participants with ADHD were randomly assigned at a 1:1 ratio to either 24 sessions of a twice-weekly hippotherapy or pharmacotherapy. To assess therapeutic effects, the ADHD Rating Scale (ARS) was used pretreatment and posttreatment as the primary outcome measure. Secondary outcomes included the Child Behavior Checklist (CBCL), Self-Esteem Scale (SES), Pediatric Quality of Life Inventory (PedsQL) child and parent report version, Developmental Coordination Disorder Questionnaire (DCDQ), Clinical Global Impressions-Severity (CGI-S), and quantitative electroencephalography. Results: Both groups showed marked improvements in ADHD symptoms, CGI-S. No significant differences between groups were detected regarding treatment outcome except thought problem subscales of CBCL. Twelve weeks of hippotherapy improved attention, impulsivity/hyperactivity, and quality of life. Conclusion: This trial is promising, but further studies are required to evaluate the long-term clinical effectiveness of hippotherapy. The study is registered with ClinicalTrials.gov, number NCT 02482649. [ABSTRACT FROM AUTHOR]

Background: Single-event multi-level chemoneurolysis (SEMLC) is a single-session procedure that treats various limbs of patients with spasticity at multiple levels with chemoneurolytic agents. Phenol is used in combination with botulinum toxin A (BTX-A) to enable spastic muscles to be treated without overdosing with BTX-A.Objective: To review unintended effects (UEs) of SEMLC for children with spastic cerebral palsy (CP).Design: Retrospective chart review.Setting: Pediatric rehabilitation outpatient clinic at an academic medical center.Participants: The study included 98 children with CP who underwent SEMLC on at least one occasion.Interventions: SEMLC.Main Outcome Measures: UEs, the goal achievement for each SEMLC session, and the Gross Motor Function Classification System (GMFCS-ER).Results: A total of 98 subjects and 146 SEMLC procedures were reviewed. Patients had a mean age of 7.56 years (standard deviation, 4.28); 57% were male; and 14 had hemiplegia, 22 had diplegia, 8 had triplegia, and 54 had quadriplegia. Most SEMLCs (72%) were performed with a combination of BTX-A and 5% phenol in a session. UEs were reported for 31/146 (21%) of SEMLC sessions, with 16 of 31 UEs being temporary weakness. The overall incidence of UEs of the group that received combined agent treatment was not different from the group that received BTX-A only (P = .267). Transient pain occurred in 7 of 105 patients who were treated with the combined agents BTX-A and phenol. Dysesthesia did not develop in any of the patients. The type of CP, GMFCS level, number of muscles injected, and doses of medications were not correlated with the incidence of UEs.Conclusions: SEMLC using combined BTX-A and phenol is a safe procedure for children with spastic CP. It could be a treatment option for patients with diffuse spasticity, because combining agents allowed more muscles to be treated without enduring or serious UEs. Patient and family education is essential to prepare them for the occurrence of common UEs, such as temporary weakness and pain. [ABSTRACT FROM AUTHOR]

Background: Mucopolysaccharidosis type I (MPS I) is caused by the deficiency of alpha-L-iduronidase (IDUA), which is involved in the degradation of glycosaminoglycans (GAGs), such as heparan sulfate and dermatan sulfate in the lysosome. It has been reported that joint symptoms are almost universal in MPS I patients, and even in the case of attenuated disease, they are the first symptom that brings a child to medical attention. However, functional tests and biological markers have not been published for the evaluation of the limitations in joint and locomotion in animal model-mimicking MPS.Methods: We generated IDUA knockout (KO) mice to observe whether they present impairment of joint function. KO mice were characterized phenotypically and tested dual-energy X-ray absorptiometry analysis (DEXA), open-field, rotarod, and grip strength.Results: The IDUA KO mice, generated by disruption between exon 6 and exon 9, exhibited clinical and laboratory findings, such as high urinary GAGs excretion, GAGs accumulation in various tissues, and significantly increased bone mineral density (BMD) in both female and male mice in the DEXA of the femur and whole bone. Remarkably, we observed a decrease in grasp function, decreased performance in the rotarod test, and hypo-activity in the open-field test, which mimic the limitations of joint mobility and decreased motor performance in the 6-min walk test in patients with MPS I.Conclusions: We generated a new IDUA KO mouse, tested open field, rotarod and grip strength and demonstrated decrease in grip strength, decreased performance and hypo-activity, which may be useful for investigating therapeutic approaches, and studying the pathogenesis of joint and locomotion symptoms in MPS I.

Objective: To investigate clinical effects of equine-assisted activities and therapy (EAA/T) for treating attention-deficit/hyperactivity disorder (ADHD) in children age 6-13 years. Methods: This 12-week, prospective, open-label trial included 24 sessions of EAA/T. Twenty participants (19 boys and 1 girl) completed 12 weeks of EAA/T. Various clinical tests were administered at baseline and after EAA/T. Assessments included the investigator-administered ADHD-Rating Scale (ARS-I), Clinical Global Impressions (CGI)-Severity Scale, Clinical Global Impressions-Improvement Scale (CGI-I), Gordon Diagnostic System, Korea-Child Behavior Checklist (K-CBCL), Self-Esteem Scale, second edition of the Bruininks-Oseretsky test of motor proficiency (BOT-2), and quantitative electroencephalography. The primary efficacy measure was the response rate. Results: The response rate was 90% based on a 30% or greater decline in the ARS-I score or 85% based on CGI-I scores of 1 or 2. The mean±standard deviation ARS-I score decreased from 33.65±6.42 at baseline to 16.80±6.86 after 12 weeks of EAA/T ( p<0.001, paired t-test). EAA/T also resulted in significant improvement in the social problems subscale of the K-CBCL and in the manual dexterity, bilateral coordination, and total motor composite subscales of the BOT-2. The theta/beta ratio on electroencephalography was decreased significantly at the Pz electrode after 12 weeks of EAA/T. Conclusion: This is the first study demonstrating that EAA/T is effective for improving core ADHD symptoms. On the basis of these results, EAA/T could be a viable treatment strategy as a part of a multimodal therapy for children with ADHD. [ABSTRACT FROM AUTHOR]

ABSTRACT Background To validate the usefulness of subacromial bursa lidocaine for determination of the therapeutic steroid injection site in patients with adhesive capsulitis Methods Ninety-two patients with adhesive capsulitis were randomly divided into the LC (lidocaine test) group (n = 46), in which LC injection was performed at the subacromial bursa prior to therapeutic steroid injection, and GH (glenohumeral) group (n = 46), in which the steroid was injected into the GH. Patients in the LC group received steroid injection at the subacromial bursa or GH according to the result of the LC. Both groups underwent the same exercise protocol. Improvement of the shoulder pain was checked at 2 weeks and 3 months postinjection and expressed on an ordinal scale. Passive range of motion was recorded preinjection, and 2 weeks and 3 months postinjection. Results Two weeks postinjection, 37 patients expressed 'much improved' and 7 patients expressed 'slightly improved' pain levels in the LC group, whereas 18 patients each expressed 'much improved' and 'slightly improved' pain levels in the GH group, which was significantly different ( p < 0.01). This difference was maintained 3 months postinjection ( p < 0.01). Passive range of motion in all directions improved significantly 3 months postinjection in both the LC and GH groups ( p < 0.01). However, there was no significant difference between the LC and GH groups. Conclusions We found that subacromial lidocaine injection prior to steroid injection resulted in better improvement of pain than conventional GH injection for patients with adhesive capsulitis. © 2014 Wiley Periodicals, Inc.

Objective: To examine whether hippotherapy has a clinically significant effect on gross motor function in children with cerebral palsy (CP). Design: Randomized controlled trial. Setting: Outpatient therapy center. Participants: Ninety-two children with CP, aged 4-10 years, presenting variable function (Gross Motor Function Classification System [GMFCS] levels I-IV). Intervention: Hippotherapy (30 minutes twice weekly for 8 consecutive weeks). Outcome measures: Gross Motor Function Measure (GMFM)-88, GMFM-66, and Pediatric Balance Scale. Results: Pre- and post-treatment measures were completed by 91 children (45 in the intervention group and 46 in the control group). Differences in improvement on all three measures significantly differed between groups after the 8-week study period. Dimensions of GMFM-88 improved significantly after hippotherapy varied by GMFCS level: dimension E in level I, dimensions D and E in level II, dimensions C and D in level III, and dimensions B and C in level IV. Conclusion: Hippotherapy positively affects gross motor function and balance in children with CP of various functional levels. [ABSTRACT FROM AUTHOR]

Objectives/Hypothesis To develop a reliable and safe laryngeal nerve conduction technique and to obtain consistent parameters as normal reference values. Study Design A prospective single-arm study. Methods A nerve conduction test was performed on the contralateral normal side in 42 patients with unilateral vocal fold palsy. The recording was performed in the intact thyroarytenoid muscle using a monopolar needle. The electrical stimulation using a 37-mm monopolar needle was applied 3 cm below the lower margin of the cricoid cartilage, just lateral to the trachea and medial to the carotid artery, and its intensity was gradually increased until the amplitude of the electrical response reached the maximum level. The latency of the evoked muscle response was acquired at the first evoked waveform deflection from the baseline. Results The average latency of the recurrent laryngeal nerves was 1.98 ± 0.26 ms. The latencies showed normal distribution according to the quantile-quantile plot and Kolmogorov-Smirnov test ( P = .098). There was no significant difference in latencies between the right and left recurrent laryngeal nerves. Anthropometric factors including height and weight did not show any correlation with the latencies. Conclusions We developed a reliable and safe laryngeal nerve conduction technique and obtained normal reference values for the recurrent laryngeal nerve conduction study. This laryngeal nerve conduction study can be an additional tool for detecting recurrent laryngeal nerve injury if it is performed in combination with the conventional laryngeal electromyography.

Background/Aims: Lymphedema is a clinically incurable disease that occurs commonly after lymph node dissection and/or irradiation. Several studies have recently demonstrated that extracorporeal shock wave therapy (ESWT) could promote lymphangiogenesis associated with expression of vascular endothelial growth factor (VEGF)-C. This research concerned primarily the synergistic effect of ESWT combined with VEGF-C incorporated hydrogel (VEGF-C hydrogel) combination therapy for promoting lymphangiogenesis and ultimately alleviating lymphedema. Methods: The VEGF-C hydrogel was applied to the injury site in a mouse model of lymphedema and then regularly underwent ESWT (0.05 mJ/mm², 500 shots) every 3 days for 4 weeks. Results: Four weeks after the treatment, mice treated with VEGF-C hydrogel and ESWT showed signs of the greatest decrease in edema/collagenous deposits when compared with the other experimental group. LYVE-1-positive vessels also revealed that the VEGF-C/ESWT group had significantly induced the growth of new lymphatic vessels compared to the other groups. Western blot analysis showed that expression of VEGF-C (1.24-fold) and VEGF receptor-3 (1.41-fold) was significantly increased in the VEGF-C/ESWT group compared to the normal group. Conclusion:These results suggested that VEGF-C and ESWT had a synergistic effect and were very effective in alleviating the symptoms of lymphedema and promoting lymphangiogenesis .

The exon-3 deletion polymorphism (d3, Database of Genomic Variants ID: Variation_64191) in the growth hormone receptor ( GHR) gene is associated with increased growth response to growth hormone (GH) therapy in GH-deficient patients. However, an association of the GHR genotype with height has not yet been reported in Prader-Willi syndrome (PWS). The aim of this study was to assess the association of GHR alleles with height before starting GH therapy in patients with PWS. Seventy-four patients with PWS were genotyped and their medical records were retrospectively reviewed (45 males and 29 females, median age 8.7 years). One hundred normal controls, with known final height, were also genotyped. The GH-exon 3 locus was genotyped using a PCR multiplex assay. The distribution of alleles in the patients with PWS was not different from controls [(fl/fl n = 53 (72%), fl/d3 n = 21 (28%)) in PWS vs. (fl/fl n = 72(72%), fl/d3 n = 26(26%), and d3/d3 n = 2(2%)]. However, patients with PWS carrying a d3 allele had significantly greater height standard deviation scores (SDS) ( P = 0.025) and higher insulin-like growth factor I (IGF-I) level ( P = 0.041), although the age at the start of GH therapy, weight, BMI, and body fat were not different. The d3 allele was associated with height and IGF-I levels before GH therapy and suggests that even before GH therapy, d3 allele may influence height through GH secretion. © 2011 Wiley Periodicals, Inc.

Although carpal tunnel syndrome (CTS) is the most common compressive neuropathy seen in the upper extremity of adults, it is rarely seen in children. Several reports have shown that mucopolysaccharidosis type II (Hunter syndrome), a rare genetic disorder, is one of the causes of CTS in children. Usual symptoms of CTS are pain, weakness, and paresthesias in the hand and digits. However, the diagnosis of CTS in Hunter syndrome is often delayed or unrecognized because of atypical symptoms and cognitive impairment. Here, we report the prevalence, clinical manifestation, and nerve conduction profiles of CTS in 45 Hunter syndrome patients. The mean age of the study participants was 117.1 (74.9) months (range: 4-408 months); all patients were male. Forty-three (96.0%) of the 45 patients with Hunter syndrome had CTS. Bilateral CTS was observed in all patients; 73 (82.0%) of the patients' hands had severe degree of CTS. Intriguingly, in contrast with other nerve velocities, decreases in forearm conduction velocities of the median nerve were observed in 28 (31.5%) of 89 hands with CTS. There was a significant difference in age ( P < 0.001) between hands with normal, mild, moderate, and severe grades of CTS. The compound muscle action potential and sensory nerve action potential amplitudes of the median nerves decreased with age (CMAP, r = −0.526, P < 0.001; SNAP, r = −0.564, P < 0.001). Early recognition and intervention to ameliorate the symptoms of CTS are important in improving the quality of life of Hunter syndrome patients. © 2011 Wiley-Liss, Inc. [ABSTRACT FROM AUTHOR]
