Brief Summary

The purpose of this study is to analyze the immediate effects of two exercises protocols on the whole body vibration, on the strength of the thigh muscles, joint position sense of the knee and balance in individuals submitted to anterior cruciate ligament reconstruction.

Conditions

Anterior Cruciate Ligament Reconstruction

Keywords

Anterior cruciate ligament; Neuromuscular Performance and balance

Outcome Measures

Primary Outcomes (1)

• Muscle Performance measured through isokinetic dynamometer

  Measured through isokinetic dynamometer. The variable analyzed will be: peak torque normalized by body weight (%).

  Change from baseline in muscle performance at one hour.

Secondary Outcomes (1)

• Muscle activation measured through surface electromyography

  Change from baseline in electromyographic activity at one hour.

Study Arms (2)

Vibration group

EXPERIMENTAL

The vibration group (Vibration at 50 Hz) will hold an exercise protocol on the vibration platform (model Power Plate® pro5 ™), which is to stay on on affected limb, with the knee held in 40 ° of flexion, hands together to the body and the trunk in the erect position. Altogether, the participant will perform 11 sets of 30 seconds with a rest interval of 30 seconds between sets. The knee angle will be monitored throughout the protocol by the second reviewer with a goniometer so that there is no change in it. During the sets the vibrating platform will be turned on at a vibration frequency of 50 Hz.

Other: Vibration at 50 Hz

Control group

NO INTERVENTION

The control group (No vibration) will hold an exercise protocol on the vibration platform, which is to stay on affected limb, with the knee held in 40 ° of flexion, hands together to the body and the trunk in the erect position. Altogether, the participant will perform 11 sets of 30 seconds with a rest interval of 30 seconds between sets. The knee angle will be monitored throughout the protocol by the second reviewer with a goniometer so that there is no change in it. The vibrating platform will remain off throughout intervention.

Interventions

Vibration at 50 Hz OTHER

During the exercise protocol, the vibration platform will be turned on at a vibration frequency of 50 Hz.
