Figure 1From: An evaluation of the 30-s chair stand test in older adults: frailty detection based on kinematic parameters from a single inertial unitRaw MTx signals during the 30-s CST of one pre-frail subject. The blue line is the X-Orientation signal, the green line is the Z-Acceleration signal and the red line is the Z-Position signal from a signal sit-stand-sit cycle. Impulse, stand-up and sit-down phases are also marked.Back to article page
