Clinical trial Recruiting at 2 sites Observational Ages 20 to 85

How aging and muscle fatigue affect balance and walking

Official title: Impacts and Mechanisms of Age and Muscle Fatigue on Postural Control and Force Control

Run by Chang Gung Memorial Hospital · NCT07405060 · Data updated 2026-11-12

This project will test whether muscle fatigue in the arms or legs changes balance and walking in healthy older adults (60–85) compared with young adults (20–40).

Is this trial a fit for you?

Likely a good fit

Ideal candidates are healthy adults willing to attend two in-person sessions: young adults aged 20–40 and older adults aged 60–85 who walk independently, have normal cognition, and have no conditions affecting motor performance.

Probably not a fit

People with neurological, cardiovascular, musculoskeletal, sensory deficits, current pain, restricted joint range, or other conditions excluded from the protocol are unlikely to benefit directly from this observational work.

What this trial studies

This repeated-measures observational project recruits healthy young (20–40) and older (60–85) adults to measure motor performance before and after fatiguing exercises of the upper and lower limbs. Participants complete two laboratory sessions at least one week apart with pre-test assessments, a protocol of repeated maximal contractions with rest, and post-test measures. Outcomes include maximal voluntary isometric contraction, postural control metrics, and gait performance while heart rate and perceived exertion are monitored for safety. Individuals with neurological, cardiovascular, musculoskeletal, sensory, or cognitive impairments are excluded to isolate age- and fatigue-related effects.

Why it matters

Potential benefit: If successful, findings could clarify how limb-specific fatigue harms balance and walking and help tailor fall-prevention and rehabilitation strategies for older adults.

How similar studies have gone: Previous research has linked neuromuscular fatigue to postural instability but results in older adults and for gait outcomes are limited and inconsistent, so this limb-specific, age-comparative approach is relatively novel.
