Abdominal muscle activity according to knee joint angle during sit-to-stand
[Purpose] This study assessed the activity of the abdominal muscles according to the angle of the knee joints during sit-to-stand. [Subjects and Methods] Thirty healthy adult males participated in this study. Subjects initiated sit-to-stand at knee joint angles of 60°, 90°, or 120°. An electromyography system was used to measure the maximum voluntary isometric contraction of the rectus abdomini...
متن کاملSliding and Lower Limb Mechanics during Sit-Stand-Sit Transitions with a Standing Wheelchair
PURPOSE This study aimed to investigate the shear displacement between the body and backrest/seat, range of motion (ROM), and force acting on the lower limb joints during sit-stand-sit transitions by operating an electric-powered standing wheelchair. METHODS AND MATERIALS The amounts of sliding along the backrest and the seat plane, ROM of lower limb joints, and force acting on the knee/foot ...
متن کاملDifferences in Trunk Accelerometry Between Frail and Nonfrail Elderly Persons in Sit-to-Stand and Stand-to-Sit Transitions Based on a Mobile Inertial Sensor
BACKGROUND Clinical frailty syndrome is a common geriatric syndrome, which is characterized by physiological reserve decreases and increased vulnerability. The changes associated to ageing and frailties are associated to changes in gait characteristics and the basic functional capacities. Traditional clinical evaluation of Sit-to-Stand (Si-St) and Stand-to-Sit (St-Si) transition is based on vis...
متن کاملSit to Stand Detection and Analysis
The ability to rise from a chair is a prerequisite for independent ambulation. Difficulty rising from a chair, moreover, is an indicator of balance deficits likely to result in a fall. In this paper we present preliminary work to affordably detect sit to stand strategies associated with balance impairment using web cameras. The long term goal is to create systems that can monitor functional mov...
متن کاملBiomechanical Analysis of Assisted Sit - to - Stand
INTRODUCTION A significant number of non-institutionalized older adults have difficulty rising from a chair [1]. Although there exist several assistive devices to aid with sit to stand, there is a lack of research that compares and analyzes various modes of assisted sit to stand to characterize their relative effectiveness in terms of biomechanical metrics. This research advances our understand...
