Peroneal Muscles Response to Expected and Unexpected Falls Among Young and Middle-aged Adults Before and After Neuromuscular Training

• Conditions: Healthy Participants
• Interventions: Other: Electromyograph Biofeedback training of the peroneal muscle

• Registration Number: NCT05006547
• Lead Sponsor: Ariel University

Brief Summary

Proper functioning of the ankle musculature, specifically peroneal muscles, is crucial for maintaining balance and reducing the risk for falls. Evidence suggests that a decrease in aspects of neuromuscular control already starts at midlife (45-65 years). However, there is almost no information regarding the function of the ankle muscles at the middle-age as most experiments have compared young (\<35 years) and older subjects (\>65 years). Moreover, neuromuscular training can improve the function of ankle muscle in response to perturbation; yet, no previous study has compared the level of effectiveness between middle-aged and young adults.

Primary Outcome Measures

Name	Time	Method
Time to stabilization	Within 24 hours	Subjects will be asked to jump from a 20 cm high box onto a force plate (i.e., expected fall).
Electromyography of peroneus longus- "Time to Onset"- expected fall	Within 24 hours	Subjects will be asked to jump from a 20 cm high box onto a force plate (i.e., expected fall). electromyography of peroneus longus will be measured the "Time to Onset" - expresses the period that passes from the beginning of the fall to the initial recruitment of the Peroneus longus.
Electromyography of peroneus longus- "Time to Peak"-unexpected fall	Within 24 hours	Subjects will stand on a platform during a unilateral sudden 30° inversion platform perturbation that resembles an unexpected fall. electromyography of peroneus longus will be measured the "Time to Peak"- describes the time it takes for the Peroneus longus muscle to reach the peak of its electrical activity.
Electromyography of peroneus longus- "The height of the amplitude"- expected fall	Within 24 hours	Subjects will be asked to jump from a 20 cm high box onto a force plate (i.e., expected fall). electromyography of peroneus longus will be measured the height of the amplitude - expresses the peak of the electrical activity of the muscles.

Maximal voluntary isometric peroneal contraction force	Within 24 hours	Subject will perform Maximal voluntary isometric peroneal contraction. The force will measured with dynamometer
