Article Synopsis
- - The study examined changes in muscle mass and quality over time in subacute stroke patients, focusing on both the affected (paretic) and unaffected (non-paretic) sides to see how these changes correlate with lower limb functions.
- - Using various measurements, including muscle thickness and shear wave elastography, the researchers found that while muscle thickness remained stable, the quality of the paretic vastus lateralis (VL) and gastrocnemius (GCM) muscles improved, whereas the non-paretic muscles showed no significant changes.
- - The results showed that improvements in muscle quality in the VL were associated with better performance on functional tests, suggesting that interventions for stroke rehabilitation should target muscle quality in the affected limbs rather
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.

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.

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.
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.
Article Synopsis
- Botulinum toxin A is a key treatment for reducing spasticity in children with cerebral palsy, influenced by factors like dosage, muscle selection, and age.
- A phase III clinical trial involving 144 children compared the effects of two types of botulinum toxin A on dynamic equinus and assessed how repeated injections impacted treatment outcomes.
- Results showed that a single injection significantly improved motor function after 3 months, while fewer injections before the study led to better gait outcomes at 6 months compared to those with multiple prior injections.
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.

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.
[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.

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.
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.
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.
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.
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.
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.
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.

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.
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).
