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

---|---|
Young adults 18<age<35 |
Other: Electromyograph Biofeedback training of the peroneal muscle
The exercise will be performed with the subject sitting in front of a computer monitor, on an elevated chair, and his feet will be in the air. The examiner will ask the subject to perform a maximum contraction of the paronal muscles, in an open kinematic chain. After reference, the subject will begin a five-minute practice. The practice will be divided into rounds of: eight seconds of muscle work and 15 seconds rest.

Outcome Measures
Primary Outcome Measures
- 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- "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.
- Electromyography of peroneus longus- "Time to Peak"- 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 Peak"- describes the time it takes for the Peroneus longus muscle to reach the peak of its electrical activity.
- 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- "The height of the amplitude"-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 "height of the amplitude" - expresses the peak of the electrical activity of the Peroneus longus muscle.
- 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- "Time to Onset"-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 Onset"- expresses the period that passes from the beginning of the fall to the initial recruitment of the Peroneus longos muscle.
- Maximal voluntary isometric peroneal contraction force [Within 24 hours]
Subject will perform Maximal voluntary isometric peroneal contraction. The force will measured with dynamometer
