18 Years - 35 Years (Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • 18-35 years
  • Unilateral ACL reconstruction
  • At least 6 months post-reconstruction
  • Recreationally active (at least 20 minutes of physical activity 3 times per week)

Exclusion Criteria:

Arms of the Study

Arm 1

Arm 2

Arm Type

Experimental

No Intervention

Arm Label

Whole Body Vibration

Control

Arm Description

The WBV intervention consists of 6 bouts of 60 seconds vibration with 2 minutes of rest in between (30Hz, 2g acceleration) while participants stand on a vibrating platform with their knees bent.

The control intervention consists of 6 bouts of 60 seconds with 2 minutes of rest in between while participants stand with their knees bent (no vibration applied).

5. Study Description

Brief Summary
Whole body vibration (WBV) acutely improves quadriceps strength, and may improve long-term outcomes in individuals with anterior cruciate ligament reconstruction (ACLR). However, it is unclear if WBV influences athletic tasks such as running. The purpose of this study is to evaluate the influence of WBV on running biomechanics in individuals with ACLR.
Detailed Description
Individuals with anterior cruciate ligament reconstruction (ACLR) have deficits in quadriceps muscles function that influences walking and running biomechanics. In the long term, alterations in walking and running contribute to physical disability and the development of knee osteoarthritis. Unfortunately, rehabilitation for the quadriceps muscles is often ineffective, and novel strategies to improve rehabilitation efforts are needed. Whole body vibration (WBV) acutely improves quadriceps strength, and may improve long-term outcomes in individuals with ACLR. However, it is unclear if WBV influences athletic tasks such as running. Specific Aim 1: The purpose of this study is to determine the effect of WBV on running biomechanics in individuals with ACLR. The investigators hypothesize that WBV will improve running characteristics associated with knee osteoarthritis development.
