]: walking = 43.2% [7.4%]; standard step = 41.2% [8.5%]; high step =34.9% [7.2%] stance). Sagittal plane ankle and midfoot joint powers were calculated as the product of joint torques and relative segment to segment angular velocities (τ·ω). 12 The ankle and midfoot positive and negative total powers were

&R test. Stretching-induced changes in flexibility were associated with changes in functional performance. The details of these findings and their implications are discussed below. Static stretching improves flexibility, joint range of motion, and joint torque. 25 – 28 Older adult fallers display reduced

, confidence in EMG measurements can be developed by investigating the relationship between joint torque and EMG amplitude. Previous research has shown relationships between EMG amplitude and isometric torque in different lower limb muscles, such as rectus femoris (RF), vastus medialis, and vastus lateralis
