Clinical Trial 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.

Eligibility

Inclusion Criteria:

• Healthy participants

Exclusion Criteria:

• Neurological disease accompanied by motor, sensory or cognitive impairment.

• Illness or condition that does not allow strenuous activity.

• Significant orthopedic injury to the back or lower limbs in the last six months, which limits strenuous activity or weight-bearing.

• Healthy Participants

Intervention

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

Type	Measure	Description	Time frame	Safety issue
Primary	Time to stabilization	Subjects will be asked to jump from a 20 cm high box onto a force plate (i.e., expected fall).	Within 24 hours
Primary	Electromyography of peroneus longus- "The height of the amplitude"- expected fall	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.	Within 24 hours
Primary	Electromyography of peroneus longus- "Time to Peak"- expected fall	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.	Within 24 hours
Primary	Electromyography of peroneus longus- "Time to Onset"- expected fall	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.	Within 24 hours
Primary	Electromyography of peroneus longus- "The height of the amplitude"-unexpected fall	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.	Within 24 hours

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