Background: Falls are more prevalent in stroke survivors than age-matched healthy older adults because of their functional impairment. Rapid balance recovery reaction with adequate range-of-motion and fast response and movement time are crucial to minimize fall risk and prevent serious injurious falls when postural disturbances occur. A Kinect-based Rapid Movement Training (RMT) program was developed to provide real-time feedback to promote faster and larger arm reaching and leg stepping distances toward targets in 22 different directions.

- The study investigates how different types of athletes (marathon runners, basketball players, and other sports athletes) exhibit varying levels of passive joint stiffness in the ankle and metatarsophalangeal (toe) joints based on their sport.
- Results showed that basketball players had significantly higher ankle and toe joint stiffness compared to the other groups.
- The findings suggest that focusing on ankle and toe strengthening exercises could enhance performance and reduce injury risks for basketball players, while vertical stiffness didn't show significant differences among groups.
This study examined whether passive metatarsophalangeal joints (MPJ) stiffness was associated with leg stiffness (Kleg) vertical stiffness (Kvert) and running economy (RE) during sub-maximal running. Nine male experienced runners underwent passive MPJ stiffness measurements in standing and sitting positions followed by sub-maximal running on an instrumented treadmill. With the individual foot position properly aligned, the MPJ passive stiffness in both sitting (MPJsit) and standing positions (MPJstand) were measured with a computerized dynamometer.

Additionally, they are important contributing structures to maintain normal foot function. Thus, weakness of these muscles may cause poor balance, inefficient locomotion and foot deformities.

Methods: Thirty-eight normal and 16 children with ASD participated with parental consent. Executive functions were measured using neuropsychological tests and parent ratings, and neurophysiologic activities were measured using EEG to yield cordance values, an indirect measure of brain perfusion.
