Effects of action observation therapy and mirror therapy after stroke on rehabilitation outcomes and neural mechanisms by MEG: study protocol for a randomized controlled trial.

BACKGROUND: Loss of upper-extremity motor function is one of the most debilitating deficits following stroke. Two promising treatment approaches, action observation therapy (AOT) and mirror therapy (MT), aim to enhance motor learning and promote neural reorganization in patients through different afferent inputs and patterns of visual feedback. Both approaches involve different patterns of motor observation, imitation, and execution but share some similar neural bases of the mirror neuron system. AOT and MT used in stroke rehabilitation may confer differential benefits and neural activities that remain to be determined. This clinical trial aims to investigate and compare treatment effects and neural activity changes of AOT and MT with those of the control intervention in patients with subacute stroke. METHODS/DESIGN: An estimated total of 90 patients with subacute stroke will be recruited for this study. All participants will be randomly assigned to receive AOT, MT, or control intervention for a 3-week training period (15 sessions). Outcome measurements will be taken at baseline, immediately after treatment, and at the 3-month follow-up. For the magnetoencephalography (MEG) study, we anticipate that we will recruit 12 to 15 patients per group. The primary outcome will be the Fugl-Meyer Assessment score. Secondary outcomes will include the modified Rankin Scale, the Box and Block Test, the ABILHAND questionnaire, the Questionnaire Upon Mental Imagery, the Functional Independence Measure, activity monitors, the Stroke Impact Scale version 3.0, and MEG signals. DISCUSSION: This clinical trial will provide scientific evidence of treatment effects on motor, functional outcomes, and neural activity mechanisms after AOT and MT in patients with subacute stroke. Further application and use of AOT and MT may include telerehabilitation or home-based rehabilitation through web-based or video teaching. TRIAL REGISTRATION: ClinicalTrials.gov, ID: NCT02871700 .

Pediatric aquatic therapy on motor function and enjoyment in children diagnosed with cerebral palsy of various motor severities.

This study investigates the effects of pediatric aquatic therapy on motor function, enjoyment, activities of daily living, and health-related quality of life for children with spastic cerebral palsy of various motor severities. Children with spastic cerebral palsy were assigned to a pediatric aquatic therapy group (n = 11; mean age = 85.0 ± 33.1 months; male : female = 4 : 7) or a control group (n = 13; mean age = 87.6 ± 34.0 months; male : female = 9 : 4). The statistic results indicate that the pediatric aquatic therapy group had greater average 66-item Gross Motor Function Measure following intervention than the control group (η(2) = 0.308, P = .007), even for children with Gross Motor Function Classification System level IV (5.0 vs 1.3). The pediatric aquatic therapy group had higher Physical Activity Enjoyment Scale scores than the control group at post-treatment (P = .015). These findings demonstrate that pediatric aquatic therapy can be an effective and alternative therapy for children with cerebral palsy even with poor Gross Motor Function Classification System level.

A large-scale nationwide newborn screening program for Pompe disease in Taiwan: towards effective diagnosis and treatment.

The aim of this study was to: (a) analyze the results of a large-scale newborn screening program for Pompe disease, and (b) establish an effective diagnostic protocol to obtain immediate, valid diagnosis of infantile-onset Pompe disease (IOPD) to promote earlier treatment and better outcomes. In this study, 402,281 newborns were screened for Pompe disease from January 1, 2008 to May 1, 2012. Infants with low acid α-glucosidase (GAA) activity were referred to Taipei Veterans General Hospital for diagnostic confirmation. Physical examination, biochemical parameter (creatine kinase [CK], alanine transaminase, aspartate aminotransferase, and lactate dehydrogenase), and echocardiogram assessments were performed immediately to effectively differentiate IOPD from suspected late-onset Pompe disease (LOPD) or false-positive cases with pseudodeficiency mutation. Six infants with IOPD all presented with hypotonia, extremely low GAA enzyme activity (≤0.5 µmol/L/hr) in initial dried blood spot analysis, high CK (≥250 U/L), and high left ventricular mass index (LVMI, ≥80 g/m(2)). By analyzing these parameters, IOPD was distinguished effectively and immediately from suspected LOPD and false-positive cases. Except for the first referred case, five of the infants with IOPD received first-time enzyme replacement therapy (ERT) within 4 hr of admission and exhibited marked improvement. Our findings indicate that certain clinical manifestations (hypotonia, high CK, enlarged LVMI, and extremely low GAA enzyme activity in initial dried blood spot analysis) can help in the rapid and effective differentiation of patients with IOPD from other patient with low GAA activity. Such differentiation allows for the early application of first-time ERT and leads to better outcomes.

Complex regional pain syndrome after transradial cardiac catheterization.

Complex regional pain syndrome (CRPS) is a disease with unclear pathophysiology. The condition is characterized by pain, soft tissue change, vasomotor change, and even psychosocial disturbance. It may affect the upper more than the lower extremities, and the distal more than the proximal. The trigger factors include carpal tunnel release, Dupuytren's repair, tendon release procedures, knee surgery, crush injury, ankle arthrodesis, amputation, and hip arthroplasty. Rarely, it has been associated with stroke, mastectomy, pregnancy, and osteogenesis imperfecta. Herein, we present a rare case of a patient who was diagnosed with CRPS after transradial cardiac catheterization. CRPS was first diagnosed due to hand swelling, allodynia, paresthesia, and the limited range of motion of interphalangeal, metacarpophalangeal, and wrist joints, with the preceding factor of transradial cardiac catheterization, and was then confirmed by a three-phase bone scan. After intensive physical therapy with hydrotherapy, manual soft tissue release, and occupational therapy for the hand function, there was much improvement in range of motion and hand function. There was no allodynia or painful sensation in the follow-up. After training, the functional status of this patient was adequate for daily activity.
