Brief Summary

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

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

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

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.

Study Groups

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

Whole Body Vibration

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.

Group Type EXPERIMENTAL

Whole Body Vibration

Intervention Type OTHER

Participants will stand in a squatted position on a platform that provides a brief vibratory stimuli.

Control

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).

Group Type NO_INTERVENTION

No interventions assigned to this group
