RESUMEN
This study aimed to evaluate the effect of a horse-riding simulator (HRS) with virtual reality (VR) on gross motor function, balance control, and body composition in children with spastic cerebral palsy (CP). Seventeen preschool and school-aged children with spastic CP were included; 10 children in the intervention group (HRS group) received 30 min of HRS with VR training twice a week for a total of 16 sessions in addition to conventional physiotherapy. Seven children in the control group were instructed to perform home-based aerobic exercises twice a week for 8 weeks in addition to conventional physiotherapy. Gross motor function measure (GMFM) and body composition were evaluated before the first session and after the last session. Before and after the 2-month intervention, Pediatric Balance Scale and Timed Up and Go test were evaluated for the HRS group. GMFM scores and body composition changed significantly in the HRS group (p < 0.05). However, no significant differences were observed in the control group. Changes in the GMFM total scores, GMFM dimension D scores, and skeletal muscle mass significantly differed between the HRS and control groups (p < 0.05). HRS with VR may be an effective adjunctive therapeutic approach for the rehabilitation of children with CP.

The horse riding simulator (HRS) reportedly has a beneficial effect on motor function and balance in children with cerebral palsy (CP). However, by itself, the HRS is not a sufficient source of challenge and motivation for children. To address this issue, we combined the HRS with virtual reality (VR) to promote somatosensory stimulation and motivation. Sixteen children (ages: 5-17 years) with CP and presenting Gross Motor Function Classification System (GMFCS) levels I-IV were enrolled in the study. Using a head-mounted display and controllers, interventions were carried out over 30-min periods (two rides lasting 12 min each, along with a six-min rest period) twice a week over a period of eight weeks (16 sessions in aggregate). The Pediatric Balance Scale (PBS), Gross Motor Function measure (GMFM)-88, and GMFM-66 scores of each participant were measured before and after the interventions. Statistically significant improvements were observed in the PBS, GMFM-66, the total GMFM-88 scores, and those corresponding to dimensions D and E of GMFM-88 after the intervention (p < 0.05). This study demonstrates that VR-incorporated HRS is effective in improving motor function and balance in children with CP and that its incorporation in conventional PT programs could yield beneficial results.

[Purpose] The aim of this study was to investigate the association between magnetic resonance imaging (MRI) findings in patients with adhesive shoulder capsulitis and the therapeutic effect of capsular distension. [Subjects and Methods] We retrospectively reviewed the medical records of 57 patients who underwent capsular distension therapy after a diagnosis of adhesive capsulitis with clinical and MRI scans. Axillary joint capsular thickness by MRI was graded as I (≤3.6â mm), II (3.7-4.2â mm), and III (≥4.3â mm). Subcoracoid fat obliteration of the rotator interval was graded subjectively as absent, partial, and complete. [Results] Capsular thickness and fat replacement were correlated with passive range of motion (PROM) and pain score on a visual analog scale (VAS) by analysis of variance with a Bonferroni correction before treatment and by analysis of covariance with a Bonferroni correction after treatment. Visual analog scale (VAS) for patients with all grades decreased significantly after treatment and passive range of motion (PROM) for patients with all grades improved. No difference was detected between grades. [Conclusion] Although MRI is useful to evaluate adhesive capsulitis, MRI findings of shoulder did not predict the prognosis after capsular distension treatment.
RESUMEN
OBJECTIVE: To analyze the changes in muscle mass and quality with time on the paretic and non-paretic sides in subacute stroke patients and identify correlations between the variation of muscle mass and quality and lower limb functions. METHODS: Thirty hemiplegia patients diagnosed with stroke participated in this study. To evaluate poststroke muscle changes, longitudinal measurement of muscle mass and quality was conducted with bilateral lower limbs. The elastic shear modulus was measured using shear wave elastography and muscle thickness (MT) of rectus femoris, vastus intermedius, vastus lateralis (VL), vastus medialis, tibialis anterior, and gastrocnemius (GCM) muscles. Functional evaluation was performed using Berg Balance Scale (BBS), Five Times Sit to Stand Test (FTSST). Follow-up was performed at discharge. The muscle mass and quality were compared according to time. We analyzed whether muscle quantity and quality were related to function. RESULTS: MT demonstrated no significant change with time. The elastic shear modulus increased significantly in the paretic VL and GCM muscles and did not change significantly in the muscles on the non-paretic side. Correlation analysis detected that elastic shear modulus in the VL has a cross-sectional negative relationship between BBS and positive relationship between FTSST. There were significant correlation between variation of FTSST and the variation of the elastic shear modulus in VL. CONCLUSION: Only paretic VL and GCM muscle quality changed in subacute stroke patients and muscle's property related to lower limb functions. Therefore, the lower extremity requires an approach to muscle quality rather than quantity for subacute stroke patients.
RESUMEN
OBJECTIVES: To evaluate the effects of hippotherapy on temporospatial parameters and pelvic and hip kinematics of gait in children with bilateral spastic cerebral palsy. DESIGN: Nonrandomized prospective controlled trial. SETTING: Outpatient therapy center. PARTICIPANTS: Children (N=32) with bilateral spastic cerebral palsy, Gross Motor Function Classification System level 1 or 2. INTERVENTION: Hippotherapy (30 min twice weekly for 8 consecutive weeks). MAIN OUTCOME MEASURES: Temporospatial parameters and pelvic and hip kinematic parameters in 3-dimensional motion analysis, Gross Motor Function Measure (GMFM)-88, and score for dimensions D (standing) and E (walking, running, jumping) of the GMFM, GMFM-66, and Pediatric Balance Scale (PBS). RESULTS: Hippotherapy significantly improved walking speed, stride length, and pelvic kinematics (average pelvic anterior tilt, pelvic anterior tilt at initial contact, pelvic anterior tilt at terminal stance). Scores for dimension E of the GMFM, GMFM-66 and PBS also increased. CONCLUSIONS: Hippotherapy provided by licensed health professionals using the multidimensional movement of the horse may be used in conjunction with standard physical therapy for improvement of gait and balance in children with bilateral spastic cerebral palsy.

BACKGROUND: Deterioration in upper extremity function has been a common problem among children with cerebral palsy (CP). The present study evaluated the effects of virtual reality (VR)-based rehabilitation combined with conventional occupational therapy (COT) on upper extremity function and caregiver assistance among children with CP. METHODS: Medical records of 17 children with CP who regularly participated in a rehabilitation program at Samsung Changwon Hospital were retrospectively reviewed. Ten children received VR-based rehabilitation, which utilized RAPAEL Smart Kids and video games combined with COT. Seven children received COT alone, which was provided by a trained occupational therapist and focused on their upper extremities. Clinical outcomes were determined using the Quality of Upper Extremity Skills Test (QUEST) and Pediatric Evaluation of Disability Inventory (PEDI), which were administered before and 8 weeks after the first intervention session. RESULTS: The smart glove (SG) group showed significant improvements in all QUEST domains and five PEDI domains (p < 0.05), whereas the COT group showed a significant change only in total QUEST scores. A comparison between both groups revealed that the SG group had significantly greater improvements in five QUEST domains and two PEDI domains (p < 0.05). CONCLUSIONS: Our results suggest that VR-based rehabilitation combined with COT may improve the upper extremity functions and decrease caregiver burden among children with CP.
RESUMEN
PURPOSE: Postoperative radiotherapy for breast cancer has a number of associated complications. This study examined whether supervised moderate-intensity exercise could mitigate the complications that occur during radiotherapy. PATIENTS AND METHODS: Forty women were randomized before radiotherapy after various operations for breast cancer. Seventeen patients who were assigned to the exercise group performed supervised moderate-intensity exercise therapy for 50 min 3 times per week for 5 weeks. Twenty-three patients in the control group were asked to perform self-shoulder stretching exercise. The World Health Organization Quality of Life-BREF (WHOQOL-BREF), brief fatigue inventory (BFI), range of motion (ROM) of the shoulder, and pain score were assessed before and after radiotherapy. RESULTS: There were no significant differences noted at baseline between groups. In the exercise group, there was an increase in the WHOQOL-BREF and shoulder ROM and decrease in BFI and pain score after radiotherapy. On the other hand, patients in the control group showed decrease in the WHOQOL-BREF and shoulder ROM and increase in BFI and pain score after radiotherapy. There were statistically significant differences in the changes in the WHOQOL, BFI, shoulder ROM, and pain score between the groups. CONCLUSION: Patients receiving radiotherapy for breast cancer may benefit in physical and psychological aspects from supervised moderate-intensity exercise therapy.

OBJECTIVE: To evaluate the validity of the Test of Infant Motor Performance (TIMP) and general movements (GMs) assessment for predicting Alberta Infant Motor Scale (AIMS) score at 12 months in preterm infants. METHODS: A total of 44 preterm infants who underwent the GMs and TIMP at 1 month and 3 months of corrected age (CA) and whose motor performance was evaluated using AIMS at 12 months CA were included. GMs were judged as abnormal on basis of poor repertoire or cramped-synchronized movements at 1 month CA and abnormal or absent fidgety movement at 3 months CA. TIMP and AIMS scores were categorized as normal (average and low average and >5th percentile, respectively) or abnormal (below average and far below average or <5th percentile, respectively). Correlations between GMs and TIMP scores at 1 month and 3 months CA and the AIMS classification at 12 months CA were examined. RESULTS: The TIMP score at 3 months CA and GMs at 1 month and 3 months CA were significantly correlated with the motor performance at 12 months CA. However, the TIMP score at 1 month CA did not correlate with the AIMS classification at 12 months CA. For infants with normal GMs at 3 months CA, the TIMP score at 3 months CA correlated significantly with the AIMS classification at 12 months CA. CONCLUSION: Our findings suggest that neuromotor assessment using GMs and TIMP could be useful to identify preterm infants who are likely to benefit from intervention.
RESUMEN
Botulinum toxin A is considered an important tool to control spasticity in children with cerebral palsy. Several factors are known to affect the efficacy of botulinum toxin, such as dosage, appropriate muscle selection and application, age, and accompanying therapy. A multicenter, double-blind, randomized, prospective phase III clinical trial of botulinum toxin A for the treatment of dynamic equinus in 144 children with cerebral palsy was performed to compare the efficacies of letibotulinumtoxin A and onabotulinumtoxin A. Secondary analyses were performed to evaluate factors that affected the outcome, focusing on the number of times injections were repeated. Effectiveness was defined as a change of 2 or more in the physician's rating scale. Multivariate regression analyses were performed with multiple variables. The first injection of botulinum toxin A significantly improved D subscale of Gross Motor Function Measure-88 scores at 3 months compared to repeated injections (p < 0.05). After 6 months, patients who had one injection or none before the study showed significantly better outcomes than those who had more than one injection in terms of observational gait scores.

The objective of this clinical trial was to compare the efficacy and safety of letibotulinum toxin A and onabotulinum toxin A for improving dynamic equinus foot deformity in children with cerebral palsy (CP). In total, 144 children with spastic CP who had dynamic equinus foot deformity were assigned randomly to the Botulax group (injection of letibotulinum toxin A) or the Botox group (injection of onabotulinum toxin A). The Physician's Rating Scale (PRS), ankle plantar flexor spasticity using the Modified Tardieu Scale, the Gross Motor Function Measure (GMFM)-88, and the GMFM-66 were completed before injection and at 6, 12, and 24 weeks after injection. The PRS responder rate was 60.27% in the Botulax group and 61.43% in the Botox group at 12 weeks after treatment, and the lower limit of the 95% confidence interval for the between-group difference in responder rates was -17.16%, higher than the non-inferiority margin of -24.00%. The clinical efficacy and the safety profiles of the groups did not significantly differ. The results suggest that injection of letibotulinum toxin A is as effective and safe as that of onabotulinum toxin A for the treatment of dynamic equinus foot deformity in children with spastic CP.

OBJECTIVE: To compare overall physical function, including gait speed and peripheral nerve function, between diabetic chronic kidney disease (CKD) patients and nondiabetic CKD patients and to investigate the association between gait speed and peripheral nerve function in CKD patients. METHODS: Sixty adult CKD patients (35 with and 25 without diabetes), who received maintenance hemodialysis (HD), were included in this study. Demographic data, past medical history, current medical condition and functional data-usual gait speed, vibration perception threshold for the index finger (VPT-F) and the great toe (VPT-T), activity of daily living (ADL) difficulty, and peripheral neuropathy (PN) along with the degree of its severity-were collected and compared between the two groups. Correlations between the severity of PN and the impairment of other functions were identified. RESULTS: Diabetic CKD patients showed significantly slower gait speed (p=0.029), impaired sensory function (VPT-F, p=0.011; VPT-T, p=0.023), and more frequent and severe PN (number of PN, p<0.001; severity of PN, p<0.001) as compared to those without diabetes. Usual gait speed had a significant negative correlation with the severity of PN (rho=-0.249, p=0.013). By contrast, VPT-F (rho=0.286, p=0.014) and VPT-T (rho=0.332, p=0.035) were positively correlated with the severity of PN. ADL difficulty was comparatively more frequent in the patients with more severe PN (p=0.031). CONCLUSION: In CKD patients with maintenance HD, their gait speed, sensory functions, and peripheral nerve functions were all significantly impaired when they have diabetes, and the severity of PN was negatively correlated with their gait speed, sensory function, and ADL function. Adverse effects of diabetes impacted physical performance of CKD patients. The physical disability of those patients might be attributable to PN and its severity.
RESUMEN
OBJECTIVE: To evaluate the overall profile of children with feeding disorders and their relationships to medical conditions in an outpatient feeding clinic of a tertiary hospital. METHODS: The medical records of 143 children who had visited the feeding clinic between January 2010 and June 2014 were reviewed retrospectively. The presence of a feeding disorder (feeding behavior disorder, dysphagia, and/or failure to thrive [FTT]) and the children's medical conditions were examined by a physiatrist. RESULTS: Half of the patients (n=74, 51.7%) were under 15 months of age, and 68 (47.6%) were born preterm. Ninety-three patients (65.0%) met the criteria for any combination of feeding behavior disorder, dysphagia, or FTT. Cardiorespiratory disease was the most common medical condition; children with this condition were more likely to show sensory food aversion and FTT. Feeding behavior disorders were significantly associated with gastrointestinal problems, and dysphagia was significantly related to almost all medical conditions. CONCLUSION: A multidisciplinary approach to children with feeding difficulties is proposed for comprehensive evaluation and treatment because combinations of feeding problems are very common among children. This overall profile could provide clinicians with a clear understanding of the complexity of feeding disorders and their relationships with various medical conditions in children.
RESUMEN
OBJECTIVE: To investigate the presence of cranial neuropathy in patients with platinum-analogue chemotherapy using electrodiagnostic evaluations. METHODS: Thirty-nine patients whose chemotherapy was completed within a month and 40 control subjects were enrolled in the study. Electrodiagnostic evaluation was performed using sensory and motor nerve conduction studies and blink reflex studies, in addition to the two-point discrimination test. RESULTS: The chemotherapy group had significantly longer latencies of bilateral R1 responses (left p<0.001; right p<0.001) and greater distance in two-point discrimination (p<0.001) compared to the control group. In the subgroup with peripheral polyneuropathy, the left R1 (p=0.01), both R2i (left p=0.02; right p=0.03) and the left R2c (p=0.02) were prolonged relative to those without the polyneuropathy, and both R1 (left p<0.001; right p<0.001), R2i (left p=0.01; right p=0.03), and the left R2c (p=0.01) were prolonged relative to the controls. On the other hand, the subgroup without the polyneuropathy showed only prolongation of both R1 (left p=0.006; right p<0.001) relative to the controls. CONCLUSION: In the present study, comparison of blink reflex and two-point discrimination showed the likelihood of subclinical cranial neuropathy following platinum-analogue chemotherapy. Cranial neuropathy caused by platinum agents was more profound in patients with peripheral polyneuropathy and may be dependent on the cumulative dose of the drug. The blink reflex may be of value in detecting subclinical cranial neuropathy in patients undergoing platinum-analogue chemotherapy.
RESUMEN
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.

OBJECTIVE: The objective of the study was to determine whether constraint-induced movement therapy (CIMT) could lead to changes in diffusion tensor tractography (DTT) associated with clinical improvement in young children with unilateral cerebral palsy (CP). METHODS: A standardized pediatric CIMT protocol (4weeks, 120h of constraint) was used on 10 children with unilateral CP who were younger than 5years. DTT was performed in five participants before and after the intervention. Clinical outcome was measured by using the Pediatric Motor Activity Log (PMAL), Quality of Upper Extremity Skills Test (QUEST), and self-care domain of the Pediatric Evaluation of Disability Inventory. RESULTS: In two patients, the affected corticospinal tract (CST) visible on pretreatment DTT became more prominent on posttreatment DTT. In one patient, the affected CST was not visible on pretreatment DTT, but was visible on posttreatment DTT. All the clinical outcomes significantly improved in the CIMT group compared with the control group. Changes in the PMAL how often scale (PMAL-HO) score significantly differed between the CIMT and control groups. CONCLUSIONS: Changes in the properties of the affected CST on DTT were accompanied with improved arm function after CIMT in the children with CP. SIGNIFICANCE: CIMT might lead to CST reorganization in young children with CP.

OBJECTIVE: To find the most effective procedure to treat adhesive capsulitis of the shoulder, we evaluated the clinical effects of an ultrasonographic-guided anterior approach capsular distension and a fluoroscopy-guided posterolateral approach capsular distension. We expected the anterior approach to be better than the posterolateral approach because the rotator interval, a triangular anatomic area in the anterosuperior aspect of the shoulder, which is considered an important component of the pathology of adhesive capsulitis. METHODS: PARTICIPANTS WERE RANDOMLY ASSIGNED TO TWO GROUPS: 27 patients in group A were injected by an anterior approach with 2% lidocaine (5 mL), contrast dye (5 mL), triamcinolone (40 mg), and normal saline (9 mL) under fluoroscopic guidance in the operating room. Twenty-seven patients in group B were injected using a posterolateral approach with 2% lidocaine (5 mL), triamcinolone (40 mg), and normal saline (14 mL) under ultrasonographic guidance. After injection, all patients received physiotherapy four times in the first postoperative week and then two times each week for eight more weeks. Treatment effects were assessed using the shoulder pain and disability index (SPADI), visual numeric scale (VNS), passive range of motion (PROM), hand power (grip and pinch) at baseline and at one week, five and nine weeks after injection. RESULTS: SPADI, VNS, PROM, and hand power improved in one week, five and nine weeks in both groups. Statistically significant differences were not observed in SPADI, VNS, PROM, or hand power between groups. CONCLUSION: Ultrasonography-guided capsular distension by a posterolateral approach has similar effects to fluoroscopy-guided capsular distension by an anterior approach.
RESUMEN
OBJECTIVE: To investigate the postural control factors influencing the automatic (reflex-controlled) and attentional (high cortical) factors on dual task. METHODS: We used a dual task model to examine the attentional factors affecting the control of posture, subjecting test subjects to vibration stimulation, one-leg standing and verbal or nonverbal task trials. Twenty-three young, healthy participants were asked to stand on force plates and their centers of pressure were measured during dual task trials. We acquired 15 seconds of data for each volunteer during six dual task trials involving varying task combinations. RESULTS: We observed significantly different sway patterns between the early and late phases of dual task trials, which probably reflect the attentional demands. Vibration stimulation perturbed sway more during the early than the late phases; with or without vibration stimulation, the addition of secondary tasks decreased sway in all phases, and greater decreases in sway were observed in the late phases, when subjects were assigned nonverbal tasks. Less sway was observed during the nonverbal task in a sequential study. CONCLUSION: The attentional and automatic factors were analyzed during a sequential study. By controlling the postural control factors, optimal parameters and training methods might be used in clinical applications.
RESUMEN
OBJECTIVE: To investigate the relationship between gross motor function and daily functional skill in children with cerebral palsy (CP) and to explore how this relationship is moderated by the Gross Motor Function Classification System, Bimanual Fine Motor Function (BFMF), neuromotor types, and limb distribution of CP. METHODS: A cross-sectional survey of 112 children with CP (range, 4 years to 7 years and 7 months) was performed. Gross motor function was assessed with the Gross Motor Function Measure-66 (GMFM-66) and functional skill was assessed with the Pediatric Evaluation of Disability Inventory-Functional Skills Scale (PEDI-FSS). RESULTS: GMFM-66 scores explained 49.7%, 67.4%, and 26.1% of variance in the PEDI-FSS scores in the self-care, mobility, and social function domains, respectively. Significant moderation by the distribution of palsy and BFMF classification levels II, III, and IV was found in the relationship between GMFM-66 and PEDI-FSS self-care. Further significant moderation by the distribution of palsy was also observable in the relationship between GMFM-66 and PEDI-FSS mobility. CONCLUSION: These findings suggest that limb distribution and hand function must be considered when evaluating gross motor function and functional skills in children with CP, especially in unilateral CP.
RESUMEN
OBJECTIVE: To determine the clinical characteristics and videofluoroscopic swallowing study (VFSS) findings in infants with suspected dysphagia and compare the clinical characteristics and VFSS findings between full-term and preterm infants. METHODS: A total of 107 infants (67 full-term and 40 preterm) with suspected dysphagia who were referred for VFSS at a tertiary university hospital were enrolled in this retrospective study. Clinical characteristics and VFSS findings were reviewed by a physiatrist and an experienced speech-language pathologist. The association between the reasons of referral for VFSS and VFSS findings were analyzed. RESULTS: Mean gestational age was 35.1±5.3 weeks, and mean birth weight was 2,381±1,026 g. The most common reason for VFSS referral was 'poor sucking' in full-term infants and 'desaturation' in preterm infants. The most common associated medical condition was 'congenital heart disease' in full-term infants and 'bronchopulmonary dysplasia' in preterm infants. Aspiration was observed in 42 infants (39.3%) and coughing was the only clinical predictor of aspiration in VFSS. However, 34 of 42 infants (81.0%) who showed aspiration exhibited silent aspiration during VFSS. There were no significant differences in the VFSS findings between the full-term and preterm infants except for 'decreased sustained sucking.' CONCLUSION: There are some differences in the clinical manifestations and VFSS findings between full-term and preterm infants with suspected dysphagia. The present findings provide a better understanding of these differences and can help clarify the different pathophysiologic mechanisms of dysphagia in infants.
RESUMEN
Several cases of acute necrotizing encephalopathy (ANE) with influenza A (H1N1) have been reported to date. The prognosis of ANE associated with H1N1 is variable; some cases resulted in severe neurologic complication, whereas other cases were fatal. Reports mostly focused on the diagnosis of ANE with H1N1 infection, rather than functional recovery. We report a case of ANE with H1N1 infection in a 4-year-old Korean girl who rapidly developed fever, seizure, and altered mentality, as well as had neurologic sequelae of ataxia, intentional tremor, strabismus, and dysarthria. Brain magnetic resonance imaging showed lesions in the bilateral thalami, pons, and left basal ganglia. To our knowledge, this is the first report of ANE caused by H1N1 infection and its long-term functional recovery in Korea.
