Whole Body Vibration on Running Biomechanics

Not Applicable

Completed

• Conditions: Knee Osteoarthritis
• Interventions: Other: Whole Body Vibration

• Registration Number: NCT02851316
• Lead Sponsor: California State University, Fullerton

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.

Arm && Interventions

Group	Intervention	Description
Whole Body Vibration	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.

Primary Outcome Measures

Name	Time	Method
Change in knee flexion excursion	Day 1, Prior to and immediately following vibration intervention in a single session (i.e. acute effects)	Knee flexion excursion during running gait
Change in ground reaction force	Day 1, Prior to and immediately following vibration intervention in a single session (i.e. - acute effects)	Ground reaction force during running gait
Change in ground reaction force loading rate	Day 1, Prior to and immediately following vibration intervention in a single session (i.e. acute effects)	Ground reaction force loading rate during running gait
