Abstract: Reduced lower limb strength in elderly is related with poor ability to functional activities, increased risk of fall, recurrent falls, and mortality. Strengthening exercise for quadriceps like stand from a seat without assistance from the upper limbs is required in elderly. For the elderly, repeated sit to stands may be sufficiently challenging to improve lower limb strength and reduce functional limitations. The researchers have developed an innovative Sit to Stand Trainer STST), a device that assists user to stand that offers variable levels of mechanical support between 20-50 kg. The STST uses a linear actuator and tension spring including parallel mechanism to produce the support system This research validated the STST in four healthy people, this research compared kinetics &Motion Analysis) of STST at 50 percent of support level to natural, unassisted Sit to Stand movement No STST) The resulting of trunk, hip, knee and ankle angles in STST are similar to No STST experimental condition Based on these results, this research can be concluded that this STST facilitates natural of sit to stand movement, which could be considered to be used in clinical rehabilitation practice.
