Upper extremity temporospatial parameters and kinematics of Filipino track and field paralympians during wheelchair Propulsion: An analysis using a Kinect-based markerless motion analysis system

@#<p style="text-align: justify;"><strong>OBJECTIVE:</strong> The potential of a low-cost, novel Kinect?-based markerless motion analysis system as a tool to measure temporospatial parameters, joint and muscle kinematics, and hand trajectory patterns during the propulsion and recovery phase of wheelchair propulsion (WCP) was determined.</p><p style="text-align: justify;"><strong>METHODS:</strong>Twenty (20) adult male track and field paralympians,(mean age = 36 ± 8.47) propelled themselves on a wheelchair ergometer system while their upper extremity motion was recorded by two Kinect? cameras and processed.</p><p style="text-align: justify;"><strong>RESULTS:</strong> The temporospatial parameters, joint kinematics, and hand trajectory patterns during the propulsion and recovery phase of each participant's WCP cycle were determined and averaged. Average cycle time was 1.45s ± 0.19, average cadence was 0.70 cycles/s ± 0.09, and average speed was 0.76m/s ± 0.32. Average shoulder flexion was 30.99° ± 28.38, average elbow flexion was 24.23° ± 12.25, and average wrist flexion was 12.82° ± 26.78. Eighty five percent (85%) of the participants used a semicircular hand trajectory pattern.</p><p style="text-align: justify;"><strong>CONCLUSION:</strong> The low-cost, novel Kinect?-based markerless motion analysis system had the potential to obtain measurable values during independent wheelchair propu

Energy Expenditure during Gait in Adults with Cerebral Palsy

OBJECTIVE: To investigate the oxygen consumption and temporospatial data according to types of cerebral palsy (CP) and to offer the basic information about the energy expenditure during gait in adults with CP. METHOD: Thirty-six adults with CP (11 spastic diplegia, 10 spastic hemiplegia, 15 athetoid type) and 24 healthy subjects were participated in this study. The parameters of energy expenditure were evaluated by KB1-C Oxymeter and temporospatial parameters during 8 meter walking were collected using Vicon 370 motion analyzer. RESULTS: Single support time was significantly decreased and double support time was significantly increased in CP spastic diplegia, compared with controls (p<0.05). Oxygen rate and oxygen cost were significantly higher in CP spastic diplegia than CP atheoid or controls. CONCLUSION: We could identify that oxygen consumption and temporospatial data of CP spastic diplegia was significantly different from athetoid or normal controls.
