Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

It is a randomized, controlled clinical trial, in healthy volunteers. They are in two groups : the test one will perform the vibration training (1h of Vibrasens 3 times a week, 24 sessions) whereas the control group will not be training. The primary outcome is the maximal voluntary strength.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

These last 10 years, a new idea born: vibrations could have potential effects on muscular reconditioning. Researchers have previously demonstrated the effects on plantar ankle flexion, with the increase of the strength, on healthy volunteers. Nowadays physicians would like to demonstrate the effects on another muscular group: ankle's dorsal flexors. 24 sessions are programmed on 8 weeks.

Moreover, the last results showed a modification of the nervous capacities of the cortical voluntary activation. Transcranial Magnetic Stimulation (TMS) is a great tool to explore the neuromuscular function, at the cortical stage. The use of this tool will allow the characterization the effects of the vibration training on the cortical activation state.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Vibrasens : Test group

Training programme: vibration training 3/week from Day 1 to Day 60 + Usual activities from day 60 to Day 75.

Group Type EXPERIMENTAL

Vibrasens

Intervention Type DEVICE

Transcutaneous vibrations are used. This device allows vibrations from 25 to 150 Hz with an amplitude of 1 mm. In our study the frequency used is 50 Hz.

Control group

Control: Usual activities from day 1 to Day 75.

Group Type ACTIVE_COMPARATOR

Usual activities

Intervention Type OTHER

The patients will perform their usual activities, to allow the comparison with a vibration programme. They will not have a specific training.
