Validation of smart device-based assessment of sit-to-stand
The sit-to-stand (STS) field test provides a relatively crude (timed or counted) outcome measure when assessing daily functional activity and quality of life. Coupling the current STS test with commercially available mobile smart device applications that can sample, store, and wirelessly transmit data strengthen the test by adding speed, velocity, and potentially power through the built in IMU. Expensive lab-based biomechanics equipment is required to obtain measures of leg power (LP) for individual repetitions during STS tasks. Modern smart devices are inexpensive, portable, user friendly, and ...
