Falls and fall-related injuries are significant public health problems in older adults. While balance-controlling strategies have been extensively researched, there is still a lack of understanding regarding how fast the lower-limb muscles contract and coordinate in response to a sudden loss of standing balance. Therefore, this pilot study aims to investigate the speed and timing patterns of multiple joint/muscles' activities among the different challenges in standing balance.

- The study examined how quickly lower-limb muscles and joints respond to unexpected balance shifts to prevent falls, using healthy young adults as subjects throughout various perturbation tests.
- Researchers recorded muscle activity and joint data using EMG and MMG techniques, analyzing factors like activation time and peak values to better understand muscle responses.
- Key findings revealed that agonist muscles activated more quickly than antagonists, ankle muscles reacted the fastest, and larger perturbations prompted quicker muscle responses, highlighting important mechanisms for maintaining balance.
