To examine an additive effect of virtual reality on balance and gait function in patients with chronic hemiparetic stroke.Twenty-four adults stroke were randomly assigned to either experimental group (n = 12) or a control group. Both groups underwent conventional physical therapy, 40 mins day, 4 days week for wks. The received additional 30 therapy each session. Balance performance was determined by the Performance Monitor Berg Scale tests. Gait 10-m walking test Modified Motor Assessment...
The present study highlights the effects of dual-task cognitive-gait intervention (CGI) on working memory and gait functions in older adults with a history falls. Thirteen falls were recruited from local communit
Sensorimotor control dysfunction or dyskinesia is a hallmark of neuromuscular impairment in children with cerebral palsy (CP), and often implicated reaching grasping deficiencies due to imbalance between the triceps bice
BACKGROUND: Neurodevelopmental treatment (NDT) and Dynamic neuromuscular stabilization (DNS)-based exercise is effective for improving core stability postural control in stroke patients. OBJECTIVE: To compare the effects of DNS conventional N
Background Arm-leg coordinated humanoid exoskeletal robots offer a solution to the ‘unnatural’ gait patterns seen in current leg-only exoskeletons, but their neuromechanical control mechanisms require further exploration. Objective This study investigates properties and modulation of cervical lumbar central pattern generators (CPGs) across different training conditions. Methods Eleven healthy adults (mean age: 25.27 ± 1.95 years; 5 females, 6 males) participated analysis involving...
To compare the therapeutic effects of a 3-dimensional corrective spinal technique (CST) and conventional exercise program (CE) on altered curvature health related quality-of-life in patients with adolescent idiopathic scoliosis (AIS).Adolescents (N=32, 6 males 26 females) between 10 19 years age (14.34 ± 2.60 years) were recruited underwent CST or CE for 60 minutes/day, 2-3 times week, an average total 30 sessions. Diagnostic X-ray imaging was used to determine intervention-related changes...
To determine the effects of a novel dynamic neuromuscular stabilization (DNS) technique on gross motor function, diaphragm movement, and activation external oblique (EO) internal (IO)/transversus abdominal (TrA) muscles in participants with cerebral palsy (CP).Fifteen CP (7 females) underwent DNS intervention for 30 minutes/day, 3 days week 4 weeks. Gross muscle were determined using function measure (GMFM-88), ultrasound, electromyography measurements, respectively, before after core...
Recent ultrasound imaging evidence asserts that the diaphragm is an important multifunctional muscle to control breathing as well stabilize core and posture in humans. However, validity accuracy of for measurement dyn
BACKGROUND: While Walkbot-assisted locomotor training (WLT) provided ample evidence on balance and gait improvements, the therapeutic effects cardiopulmonary psychological elements as well fall confidence are unknown in stroke survivors. OB
Background: While the biomechanical characteristics of golf swing are well established, lumbopelvic kinematic professional golfers with limited hip internal rotation warrant further investigation. Purpose: The specific aim was to ascertain mechanical differences in lumbopelvic-hip movement asymptomatic and without during swing. Study Design: Controlled laboratory study. Methods: Thirty male (aged 25-35 years 0 handicap matched) were classified into either motion (LHIM) group (range <20°)...
BACKGROUND: Robot-assisted and treadmill-gait training are promising neurorehabilitation techniques, with advantages over conventional gait training, but the neural substrates underpinning locomotor control remain unknown particularly during differen
BACKGROUND: Postural core instability is associated with poor dynamic balance and a high risk of serious falls.Both neurodevelopmental treatment (NDT) neuromuscular stabilization (DNS) exercises have been used to improve stability, but the outcomes these treatments remain unclear.OBJECTIVE: This study was undertaken examine therapeutic effects NDT DNS on muscular activity, muscle thickness.METHODS: Ten participants (5 healthy adults; 5 hemiparetic stroke patients) were recruited.Surface...
Abstract Detecting neuroplastic changes during locomotor neurorehabilitation is crucial for independent primal motor behaviours. However, long-term training-related neuroplasticity remains unexplored. We compared the effects of end-effector robot-assisted gait training (E-RAGT) and bodyweight-supported treadmill (BWST) on cortical activation in individuals with hemiparetic stroke. Twenty-three men five women aged 53.2 ± 11.2 years were recruited randomly assigned to participate E-RAGT (n =...
Although clinical machine learning (ML) algorithms offer promising potential in forecasting optimal stroke rehabilitation outcomes, their specific capacity to ascertain favorable outcomes and identify responders robotic-assisted gait training (RAGT) individuals with hemiparetic undergoing such intervention remains unexplored.
Objective: To identify the effect of a novel augmented core stabilization exercise technique on physical function, pain and stability in patients with chronic low back pain. Design: A block randomized controlled trial two groups. Setting: sports rehabilitation clinic. Participants: Forty (20 experimental, mean (SD) age 50.35 (9.26) years 20 control, 51.30 (7.01)), 19 men 21 women.

Abstract Abnormal spasticity and associated synergistic patterns are the most common neuromuscular impairments affecting ankle–knee–hip interlimb coordinated gait kinematics kinetics in patients with hemiparetic stroke. Although stroke undergo various treatments to improve movement, it remains unknown how change after robot-assisted conventional treatment. We developed an innovative humanoid robot (ICT) mitigate abnormal patterns. The objective of preliminary clinical trial was compare...
