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.

Arms and Interventions

Arm Intervention/Treatment
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.

Middle aged adults

50<age<65

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

  1. 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).

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

  7. 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.

  8. Maximal voluntary isometric peroneal contraction force [Within 24 hours]

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