Comparison Between M-Mode Ultrasonography and Fluoroscopy for Diaphragm Excursion Measurement in Patients With Acquired Brain Injury.

OBJECTIVES: Patients with acquired brain injury show decreased pulmonary function and diaphragm excursion (DE), which can affect functional outcomes. This study aimed to compare ultrasonography (US) and fluoroscopy for DE assessment and to determine how the relationship between pulmonary function test results and DE differs according to the paralytic condition. METHODS: From September 2017 to April 2018, we prospectively enrolled patients with acquired brain injury. The patients underwent a pulmonary function test, including the functional vital capacity, forced expiratory volume at 1 second, forced expiratory volume at 1 second-to-functional vital capacity ratio, peak cough flow, and respiratory muscle strength such as the maximal inspiratory pressure and maximal expiratory pressure. Diaphragm excursion was measured with M-mode US and fluoroscopy on admission. A partial correlation analysis was used to assess the correlation between US and fluoroscopy for DE assessment. RESULTS: During the study period, 50 patients with acquired brain injury were enrolled. After adjusting for age, sex, height, and weight, the correlation coefficients between US and fluoroscopy were 0.744 for the right side (P < .001) and 0.631 for the left side (P < .001). In a subgroup analysis for patients with hemiplegia, the correlation coefficients were 0.507 for the paretic side (P = .007) and 0.677 for the nonparetic side (P < .001). Diaphragm excursion in the nonparetic side was significantly correlated with the maximal inspiratory pressure, maximal expiratory pressure, and peak cough flow (P < .05). CONCLUSIONS: M-mode US can be an alternative method for DE measurement in patients with impaired locomotion function after acquired brain injury. Preserved function of the nonparetic side might affect pulmonary function after brain injury, which suggests the importance of prestroke respiratory function.

Lesions Responsible for Delayed Oral Transit Time in Post-stroke Dysphagia.

INTRODUCTION: Some stroke patients show oral phase dysphagia, characterized by a markedly prolonged oral transit time that hinders oral feeding. The aim of this study was to clarify the clinical characteristics and lesions responsible for delayed swallowing. METHODS: We reviewed 90 patients with stroke. The oral processing time plus the postfaucial aggregation time required to swallow semisolid food was assessed. The patients were divided into two groups according to oral transit time, and we analyzed the differences in characteristics such as demographic factors, lesion factors, and cognitive function. Logistic regression analyses were performed to examine the predictors of delayed oral transit time. Lesion location and volume were measured on brain magnetic resonance images. We generated statistic maps of lesions related to delayed oral phase in swallowing using voxel-based lesion symptom mapping (VLSM). RESULTS: The group of patients who showed delayed oral transit time had significantly low cognitive function. Also, in a regression model, delayed oral phase was predicted with low K-MMSE (Korean version of the Mini Mental Status Exam). Using VLSM, we found the lesion location to be associated with delayed oral phase after adjusting for K-MMSE score. Although these results did not reach statistical significance, they showed the lesion pattern with predominant distribution in the left frontal lobe. CONCLUSION: Delayed oral phase in post-stroke patients was not negligible clinically. Patients' cognitive impairments affect the oral transit time. When adjusting it, we found a trend that the lesion responsible for delayed oral phase was located in the left frontal lobe, though the association did not reach significance. The delay might be related to praxis function.

Comparison of the Forefoot Pressure-Relieving Effects of Foot Orthoses.

PURPOSE: Metatarsal pads are prescribed to decrease forefoot plantar pressure. However, the appropriate metatarsal pad placement location remains a debated issue. We aimed to identify the most effective insole design that reduces forefoot plantar pressure and determine the optimal position for metatarsal pad placement. MATERIALS AND METHODS: We recruited 16 healthy adult volunteers, and measured their plantar pressure data during walking while using an in-shoe system. The volunteers were randomly assigned to one of four insole conditions: 1/16-inch insole (i.e., control), 1/4-inch soft plastazote (SP) flat insole, metatarsal pad positioned proximal to the metatarsal head (MTH) on the control insole (P0), and metatarsal pad positioned 10 mm distal from the proximal border of the MTH on the control insole (P10). A masking protocol was created by dividing the forefoot into three subareas, distal to the MTH (dMTH), beneath to the MTH (bMTH), and proximal to the MTH (pMTH). The participants reported their comfort level for each insole using a visual analog scale. RESULTS: The SP flat insole and metatarsal pads both had a forefoot plantar pressure-reducing effect and provided insole comfort. Of the three insole designs, the SP flat insole was the most effective. No clear difference existed in efficacy in terms of the location of the metatarsal pad placement. CONCLUSION: Considering the possibility of discomfort caused by improper metatarsal pad placement, the SP that increases shock absorption may be more clinically useful.

Establishment of muscle mass-based indications for the cystatin C test in renal function evaluation.

Background: We aimed to suggest muscle mass-based criteria for using of the cystatin C test for the accurate estimated glomerular filtration rate (eGFR). Materials and methods: We recruited 138 Korean subjects and evaluated eGFRcr (derived from Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) based on creatinine) was compared to eGFRcys based on cystatin C as the reference value. The skeletal muscle mass index (SMI) by bioelectrical impedance analysis (BIA) was used as representative of muscle mass. Calf circumference (CC) was also evaluated. We defined the patients by eGFRcr as those with values of eGFRcr ≥ 60 mL/min/1.73 m2 but eGFRcys < 60 mL/min/1.73 m2 as the detection of hidden renal impairment (DHRI). Cut-off values were determined based on muscle mass for the cases of DHRI suggesting the criteria of cystatin C test in renal function evaluation. Results: We confirmed significant negative correlation between %difference of eGFRcr from eGFRcys and SMI (r, -0.592 for male, -0.484 for female) or CC (r, -0.646 for male, -0.351 for female). SMI of 7.3 kg/m2 for males and 5.7 kg/m2 for females were suggested to be significant cutoffs for indication of cystatin C test. We also suggested CC would be valuable for cystatin C indication. Conclusion: We suggested the muscle mass-based objective criteria relating to SMI and CC that would indicate the use of cystatin C to evaluate renal function test in sarcopenic cases. Our results highlight the importance of muscle mass-based selection of renal function.

Effects of Typical Athletic Shoes on Postural Balance According to Foot Type.

BACKGROUND: The effects of shoes and foot type on balance are unclear. We aimed to investigate the differences between static and dynamic balance among three foot types and the changes in postural balance while wearing typical athletic shoes. METHODS: Based on the Foot Posture Index, the feet of 39 participants were classified as pronated, neutral, or supinated by a physiatrist. Static and dynamic balance function were assessed by center of gravity (COG) sway velocity with eyes open and eyes closed and a modified Star Excursion Balance Test in a random order with participants either barefoot or wearing shoes. RESULTS: The COG sway velocity was significantly higher in the supinated foot group than in the neutral foot group (barefoot: eyes open, P = .004, eyes closed, P = .001). Normalized composite reach distance (NCRD) was significantly lower in the pronated and supinated foot groups (barefoot: P = .039, P = .008; shoes: P = .018, P = .018). In all three foot type groups, COG sway velocity was significantly decreased (P < .05) and NCRD was significantly increased (P < .05) while wearing typical athletic shoes. CONCLUSIONS: The medial longitudinal arch of the foot affects postural balance. Typical athletic shoes improve postural balance regardless of foot type. However, the pronated and supinated foot groups still had lower dynamic postural balance compared with the neutral foot group, even when wearing athletic shoes. People with pronated and supinated feet may need additional interventions, such as foot orthoses or balance training.

Balance Ability in Low Back Pain Patients With Lumbosacral Radiculopathy Evaluated With Tetrax: A Matched Case-Control Study.

OBJECTIVE: To compare postural balance ability in patients with low back pain between groups with and without lumbosacral radiculopathy. METHODS: Patients who were referred for electromyography because of low back pain during the period from April 2017 through June 2018 were chosen as subjects. They were divided into groups with and without lumbosacral radiculopathy based on the results of electromyography. We used Tetrax (Sunlight Medical Ltd., Ramat Gan, Israel) to objectively evaluate postural balance ability, and to measure the fall risk, stability index, weight distribution index, and Fourier index. RESULTS: Patients in the lumbosacral radiculopathy group showed significantly higher fall risk (73.25 vs. 38.00; p<0.05), weight distribution index (8.57 vs. 5.00; p<0.05), and stability index (21.19 vs. 13.16; p<0.05) than those in the group without lumbosacral radiculopathy. The Fourier index at high-medium frequency was significantly increased in the lumbosacral radiculopathy group (8.27 vs. 5.56; p<0.05), whereas weight-bearing on the side of radiculopathy was significantly decreased. CONCLUSION: Patients with lumbosacral radiculopathy have decreased postural balance compared with patients without this condition. Somatosensory disturbances in lumbosacral radiculopathy might cause postural balance impairment. Assessment and treatment plan not only for pain reduction but also for postural balance improvement should be considered in the management of patients with lumbosacral radiculopathy.

Effects of adjuvant mental practice using inverse video of the unaffected upper limb in subacute stroke: a pilot randomized controlled study.

Mental practice has shown some positive effects on arm and hand ability and mobility after stroke. This study's objective was to investigate the adjuvant effects of mental practice using an inverse video of the unaffected limb in subacute stroke patients with severe motor impairment on motor improvement, functional outcomes, and activities of daily living. Participants (n = 20) with severe hemiplegia after a unilateral first-ever stroke within 6 months were divided into two groups. The intervention group performed additional mental practice using an inverse video of the unaffected limb for 20 minutes before every session of their rehabilitation program. The primary outcomes were the Fugl-Meyer assessment for the upper extremity (FMA-UE) and manual function test (MFT). Assessments were performed at baseline and after 4 weeks of rehabilitation intervention. Significant differences were found from baseline to postintervention assessments within both groups on FMA-UE and FIM scores, whereas there were no statistically significant differences in mean FMA-UE, MFT, and FIM scores between groups. We cannot draw conclusions about the superiority of adjuvant mental practice training using inverse video compared with conventional occupation therapy alone in subacute poststroke patients.

Is there a dose-dependent effect of modified constraint-induced movement therapy in patients with hemiplegia?

BACKGROUND: Impairment of upper extremity function is a common sequelae of stroke. It has been reported that modified constraint-induced movement therapy (mCIMT) could prove to be effective. OBJECTIVE: To investigate the relationship between the intensity of rehabilitation such as treatment and constraining time, and the functional outcome for the paretic upper extremity in stroke patients through mCIMT. METHODS: We conducted an observational prospective study of 31 patients with hemiplegia and subacute or chronic stroke. The mCIMT was performed for two weeks. Rehabilitation time and constraining time were variable among patients. The rehabilitation time included an individualized task-oriented program and conventional occupation treatment with an individualized therapist. The constraining time, with mit or splint, was also asked to self-record individually. The outcome was evaluated on the more affected side by the Wolf Motor Function Test, Fugl-Meyer Assessment, Motor Activity Log 14, and Functional Independence Measure for self-care tasks after the therapy. RESULTS: All participants after the modified constraint-induced movement therapy program for two weeks improved on the evaluated outcome measures (P < 0.05). No significant correlation was found between the dose-dependent treatment or constraining time and outcomes. Comparisons improvement with subgroups based on the duration from onset, constraining component, dominant hand consistent with lesion side of stroke, and initial medical research council score for muscle strength, also showed no significant differences. CONCLUSIONS: This is the first study on the effects of intensity of mCIMT with respect to time-dosage. Although all patients in this study showed improved functional status, no significant correlation between dose-dependent rehabilitation or constraining time and outcomes was seen.

Predictors of functional and motor outcomes following upper limb robot-assisted therapy after stroke.

Robot-assisted therapy is an effective treatment for stroke patients and has recently gained popularity. Clinicians and researchers are trying to identify predictors to stratify patients for ensuring better stroke rehabilitation outcomes. However, previous studies have reported controversial results regarding the predictors of upper limb recovery after robot-assisted therapy. Our objective was to determine whether the demographic and clinical characteristics of stroke patients influence the motor and functional outcomes after robot-assisted therapy. We conducted a retrospective analysis of 48 hemiplegic patients who performed upper limb goal-directed tasks using RAPAEL Smart Glove (Neofect, Gyeonggi-do, Republic of Korea). Robot-assisted therapy was administered for 5 days a week over 4 weeks, and each session was for 30 minutes. The parameters of the primary outcomes after robot-assisted therapy were measured with the manual function test and functional independence measure. Correlation analysis showed that age, initial cognitive function, and the initial manual function test and the Modified Ashworth Scale for upper extremity scores were significant factors for independently predicting functional outcomes after robot-assisted therapy. Linear regression analysis revealed that the initial Mini-Mental State Examination (P < 0.001) and initial manual function test (P < 0.001) scores were significant predictors of the primary outcomes. In conclusion, our study suggests that stroke patients presenting with less spasticity, better initial cognitive function, and better initial motor function have a significant correlation with the functional outcomes after robot-assisted therapy.

Relationship Between Functional Level and Muscle Thickness in Young Children With Cerebral Palsy.

OBJECTIVE: To investigate the relationship between functional level and muscle thickness (MT) of the rectus femoris (RF) and the gastrocnemius (GCM) in young children with cerebral palsy (CP). METHODS: The study participants were comprised of 26 children (50 legs) with spastic CP, aged 3-6 years, and 25 age-matched children with typical development (TD, 50 legs). The MT of the RF, medial GCM, and lateral GCM was measured with ultrasound imaging. The functional level was evaluated using the Gross Motor Function Measurement-88 (GMFM-88), Gross Motor Function Classification System (GMFCS), and based on the mobility area of the Korean version of the Modified Barthel Index (K-MBI). The measurement of spasticity was evaluated with the Modified Ashworth Scale (MAS). RESULTS: We note that the height, weight, body mass index, and MT of the RF, and the medial and lateral GCM were significantly higher in the TD group (p<0.05). There was a direct relationship between MT of the RF and medial GCM and the GMFM-88, GMFCS, and mobility scores of the K-MBI in individuals with early CP. In addition, we have noted that there was a direct relationship between MT of the lateral GCM and the GMFM-88 and GMFCS. Although there was a tendency toward lower MT with increasing MAS ratings in the knee and ankle, the correlation was not statistically significant. CONCLUSION: In young children with CP, MT of the RF and GCM was lower than in age-matched children with TD. Furthermore, it is noted with confidence that a significant positive correlation existed between MT and functional level as evaluated using the GMFM-88, GMFCS, and mobility area of K-MBI.

Feedback Facility-Assisted Balance Training in a Patient With Multiple System Atrophy: A Case Presentation.

Multiple system atrophy is a rare neurodegenerative disease with a poor prognosis. Furthermore, there are no pharmacological or notable rehabilitation strategies available to prevent the worsening of the disease. This case presentation assessed the outcome of feedback facility-assisted balance training in combination with physical therapy in a 61-year-old man. The patient participated in 30 training sessions over 6 weeks for 30 minutes each that involved balance training. His static and dynamic balance abilities were improved on the Berg Balance Scale, Trunk Impairment Scale, Functional Independence Measure, and Functional Reach. Although this patient's gait speed and muscle strength did not show improvement after training, feedback facility-assisted balance training might be a potential strategy to help reduce the rate of symptom deterioration in patients with multiple system atrophy. LEVEL OF EVIDENCE: V.

Investigating the Dose-Related Effects of Video Game Trunk Control Training in Chronic Stroke Patients With Poor Sitting Balance.

OBJECTIVE: To investigate the dose-related effect of trunk control training (TCT) using Trunk Stability Rehabilitation Robot Balance Trainer (TSRRBT) in chronic stroke patients with poor sitting balance. METHODS: This was a retrospective study of 38 chronic stroke patients with poor sitting balance that underwent TCT with TSRRBT. The participants were assigned either to the low-dose training (LDT) group (n=18) or to the highdose training (HDT) group (n=20). In addition to the conventional rehabilitation therapy, the LDT group received 5 sessions of TSRRBT intervention per week, whereas the HDT group received 10 sessions of TSRRBT intervention per week. The outcome measures were the scores on the Trunk Impairment Scale (TIS) and its subscales, Berg Balance Scale (BBS), Functional Ambulation Classification (FAC), and the Korean version of Modified Barthel Index (K-MBI). All outcome measures were assessed before the training and at the end of the 4-week training. RESULTS: After the 4-week intervention, TIS, BBS, FAC, and K-MBI scores showed improvement in both LDT and HDT groups. Furthermore, the improvements in TIS scores and its subscales were significantly greater in the HDT group than in the LDT group (p<0.05). CONCLUSION: TCT using TSRRBT could be an additional treatment for the conventional rehabilitation therapy of chronic stroke patients with poor sitting balance. HDT may provide more beneficial effects on improving patients' sitting balance than LDT.

Clinical and Biomechanical Effects of Low-Dye Taping and Figure-8 Modification of Low-Dye Taping in Patients With Heel Pad Atrophy.

OBJECTIVE: To investigate and compare the effect of low-dye taping (LDT) and figure-8 modification of LDT (MLDT) on peak plantar pressure and heel pain in patients with heel pad atrophy. METHODS: There were reviewed 32 feet of 19 patients who have been diagnosed with heel pad atrophy who were enrolled in this study. The patients were diagnosed with heel pad atrophy with clinical findings, and loaded heel pad thickness measured by ultrasonography. At the first visit, patients were taught how to do LDT and MLDT. They were instructed to do daily living with barefoot, LDT and MLDT at least one time per day. Patients performed pedobarography with barefoot, LDT and MLDT within 2 weeks. The severity of heel pain was also checked with the visual analogue scale (VAS) during daily living with barefoot, LDT and MLDT. RESULTS: VAS of hindfoot were significantly decreased after LDT and MLDT (p<0.01). Peak plantar pressure under hindfoot were also decreased after LDT and MLDT (p<0.01). The effect of MLDT in decreasing peak plantar pressure of hindfoot (p<0.01) and pain relief (p=0.001) was better than the effect of LDT. CONCLUSION: The LDT technique is clinically useful for pain management and reducing peak plantar pressure of hindfoot in patients with heel pad atrophy. MLDT is more effective than LDT in reducing peak plantar pressure and heel pain in patients with heel pad atrophy.

Usefulness of Submental Ultrasonographic Evaluation for Dysphagia Patients.

OBJECTIVE: To investigate the usefulness of ultrasonographic measurement of hyoid bone movement during swallowing. METHODS: Fifty-two patients who had swallowing dysfunction were enrolled in this study. When a patient swallowed 5 mL of water while maintaining an upright sitting position, hyoid bone movement during swallowing was measured with ultrasonography. Recorded images were analyzed to measure the maximum change in hyoid bone displacement. Mandible was used as reference point to calculate hyoid bone displacement. The farthest distance from resting position and the nearest distance during swallowing were measured and their differences were recorded. Participants also underwent videofluoroscopic swallowing study (VFSS). Based on penetration-aspiration scale (PAS), they were grouped to non-aspirators (PAS 1), penetrators (PAS 2-5), or aspirators (PAS 6-8). Measured hyoid bone displacements by submental ultrasonography were compared among groups. RESULTS: The mean hyoid bone displacement in non-aspirators group (n=21, 15.9±2.7 mm) was significantly (p<0.05) greater than that in penetrators group (n=20, 11.5±2.8 mm) or aspirators group (n=11, 8.0±1.0 mm). Hyoid bone displacement below 13.5 mm as a cutoff point for detecting penetration or aspiration had a sensitivity and specificity of 83.9% and 81.0%, respectively. CONCLUSION: Submental ultrasonographic evaluation was well correlated with PAS measured by VFSS. Therefore, submental ultrasonographic evaluation could be a useful screening tool for dysphagic patients.

Calcaneal Osteomyelitis due to Non-tuberculous Mycobacteria: A Case Report.

Osteomyelitis is a bone infection caused by bacteria or other germs. Gram-positive cocci are the most common etiological organisms of calcaneal osteomyelitis; whereas, non-tuberculous mycobacteria (NTM) are rarely documented. We reported a case of NTM calcaneal osteomyelitis in a 51-year-old female patient. She had been previously treated in many local clinics with multiple local steroid injection over 50 times and extracorporeal shock-wave therapy over 20 times with the impression of plantar fasciitis for 3 years prior. Diagnostic workup revealed a calcaneal osteomyelitis and polymerase chain reaction assay on bone aspirate specimens confirmed the diagnosis of non-tuberculous mycobacterial osteomyelitis. The patient had a partial calcanectomy with antitubercular therapy. Six months after surgery, a follow-up magnetic resonance imaging showed localized chronic osteomyelitis with abscess formation. We continued anti-tubercular therapy without operation. At 18-month follow-up after surgery and comprehensive rehabilitation therapy, she was ambulating normally and able to carry out her daily activities without any discomfort.

Therapeutic effect of repetitive magnetic stimulation combined with speech and language therapy in post-stroke non-fluent aphasia.

OBJECTIVE: To investigate the therapeutic effect of repetitive transcranial magnetic stimulation (rTMS) and speech and language therapy (SLT) on the improvement of performance on the Korean-version of the Western Aphasia Battery (K-WAB) in post-stroke non-fluent aphasic patients. METHODS: Twenty post-stroke, non-fluent aphasic patients were enrolled and assigned to one of two groups: a case group (n = 10) or a control group (n = 10). Participants were recruited from the inpatient clinic of the Physical and Rehabilitation Medicine Department of Bundang Jesaeng General Hospital from March 2011 to January 2012. The case group received rTMS and SLT and the control group received SLT; both groups received these therapies for four weeks. Language functioning was evaluated using K-WAB before and after treatment. RESULTS: There were no significant differences between the groups' baseline characteristics and initial values (p > 0.05). After four weeks of therapy, there were significant improvements in repetition and naming in the case group (p < 0.05). However, there was no significant improvement in the control group (p > 0.05). CONCLUSIONS: rTMS combined with SLT can be an effective therapeutic method for treating aphasia in post-stroke non-fluent aphasic patients, although additional controlled and more systemic studies should be conducted.

Participation in leisure activity and exercise of chronic stroke survivors using community-based rehabilitation services in seongnam city.

OBJECTIVE: To clarify how participation in leisure activities and exercise by chronic stroke survivors differs before and after a stroke. METHODS: Sixty chronic stroke survivors receiving community-based rehabilitation services from a health center in Seongnam City were recruited. They completed a questionnaire survey regarding their demographic characteristics and accompanying diseases, and on the status of their leisure activities and exercise. In addition, their level of function (Korean version of Modified Barthel Index score), risk of depression (Beck Depression Inventory), and quality of life (SF-8) were measured. RESULTS: After their stroke, most of the respondents had not returned to their pre-stroke levels of leisure activity participation. The reported number of leisure activities declined from a mean of 3.9 activities before stroke to 1.9 activities post-stroke. In addition, many participants became home-bound, sedentary, and non-social after their stroke. The most common barriers to participation in leisure activities were weakness and poor balance, lack of transportation, and cost. The respondents reported a mean daily time spent on exercise of 2.6±1.3 hours. Pain was the most common barrier to exercise participation. CONCLUSION: Chronic stroke survivors need information on leisure activities and appropriate pain management.

The relationships between determination of treatment success and emotional factors in patients with chronic musculoskeletal pain.

OBJECTIVE: To investigate the relationship of the patient's criteria of successful treatment to emotional factors in patients with chronic musculoskeletal pain. METHODS: Patients who visited our outpatient hospital due to chronic musculoskeletal pain were evaluated using a questionnaire survey. Patients were evaluated with the Patient-Centered Outcomes Questionnaire (PCOQ) to investigate their expectation and criteria for success regarding treatment of chronic musculoskeletal pain. Beck Depression Inventory and State-Trait Anxiety Inventory were used to check for psychological variables. Correlations among each of the variables were evaluated statistically. RESULTS: Patients with higher levels of depression and anxiety needed larger improvements to consider the treatment as a success in the pain domain (depression, r=0.398, p=0.04; anxiety, r=0.447, p=0.02) and emotional distress domain (depression, r=0.617, p=0.001; anxiety, r=0.415, p=0.03), but had lower level of expectation of the treatment in the pain domain (depression, r=-0.427, p=0.01; anxiety, r=-0.441, p=0.004), emotional distress domain (depression, r=-0.454, p=0.01; anxiety, r=-0.395, p=0.04), and interference of daily activities domain (depression, r=-0.474, p=0.01; anxiety, r=-0.396, p=0.04). Patients were classified into 3 clusters based on the importance rating of each domain via a hierarchical analysis. The cluster of the patients with the higher rating of importance across all domains (importance of pain domain, 9.54; fatigue domain, 9.08; emotional distress domain, 9.23; interference of daily activities domain, 9.23) had the highest level of depression and anxiety. CONCLUSION: Consideration of psychological factors, especially in patients who require larger improvements in all treatment domains, may be helpful for the successful treatment of chronic musculoskeletal pain.

Contributing factors analysis for the changes of the gross motor function in children with spastic cerebral palsy after physical therapy.

OBJECTIVE: To investigate the factors which contribute to the improvements of the gross motor function in children with spastic cerebral palsy after physical therapy. METHODS: The subjects were 45 children with spastic cerebral palsy with no previous botulinum toxin injection or operation history within 6 months. They consisted of 24 males (53.3%) and 21 females (46.7%), and the age of the subjects ranged from 2 to 6 years, with the mean age being 41±18 months. The gross motor function was evaluated by Gross Motor Function Measure (GMFM)-88 at the time of admission and discharge, and then, the subtractions were correlated with associated factors. RESULTS: The GMFM-88 was increased by 7.17±3.10 through 52±16 days of physical therapy. The more days of admission, the more improvements of GMFM-88 were attained. The children with initial GMFM-88 values in the middle range showed more improvements in GMFM-88 (p<0.05). The children without dysphagia and children with less spasticity of lower extremities also showed more improvements in GMFM-88 (p<0.05). CONCLUSION: We can predict the improvements of the gross motor function after physical therapy according to the days of admission, initial GMFM-88, dysphagia, and spasticity of lower extremities. Further controlled studies including larger group are necessary.

Motor Axonal Neuropathy Associated With Idiopathic CD4(+) T-Lymphocytopenia.

Idiopathic CD4(+) T-lymphocytopenia is a rare immune disorder characterized by an unexplained deficit of CD4(+) T cells and results in various opportunistic infections. Herein, we report a case of new onset weakness in a 10-year-old boy secondary to motor axonal neuropathy associated with idiopathic CD4(+) T-lymphocytopenia. The patient was referred to rehabilitation for an evaluation of progressive weakness involving all four limbs. A subsequent nerve conduction study and needle electromyography identified motor axonal neuropathy. At that time, laboratory studies specific to the differential diagnosis of motor axonal neuropathy were performed; however, the abnormality noted was a decreased CD4(+) T-lymphocyte count. Motor axonal neuropathy represents an uncommon manifestation of idiopathic CD4(+) T-lymphocytopenia and is probably associated with an underlying immune process.
