Lumbar Thrust-mobilization Effects on Hip Strength and Anterior Knee Pain

Not Applicable
Conditions
Anterior Knee Pain Syndrome
Registration Number
NCT04119310
Lead Sponsor
Messiah College
Brief Summary

The purpose of this study is to investigate changes in lateral hip muscle strength as well as self-reported pain during the performance of three functional tests in patients with anterior knee pain following a lumbopelvic thrust-mobilization.

Hypothesis(es):

Lumbar thrust-mobilization will lead to increased lateral hip strength and decreased anterior knee pain during 3 functional activities (single leg step down, functional squat, drop jump).

Detailed Description

The participant will complete a medical history form and undergo a brief physical exam of the lumbar spine and knees to include: lumbar range of motion and mobility testing, knee range of motion, palpation, and knee mobility testing. The participant will complete a hip strength test utilizing the Biodex System 4 Pro®. The participant will then perform three activities (single leg step down, squat, and drop jump from a 2 foot platform) and provide a self-reported knee pain measure with each activity. A sealed envelope indicating the intervention to be received will be given to the participant. An investigator blinded to the pre and post-measures will open the envelope indicating the intervention to be performed. The participant will be blinded to which intervention group they are categorized to. Th e participant will be positioned on a high-low treatment table to receive the assigned intervention. The participant will be positioned to receive either intervention 1 (thrust mobilization) or 2 (sham mobilization). The participant will either receive the thrust-mobilization or sham mobilization up to 2 times on the left and right side. An immediate re-test of hip strength will be conducted followed by performing the same three functional activities (single leg step down, squat, and drop jump from a 2 foot platform) while providing a self-reported pain measure after each activity. Follow-up measures at 15 minutes post-intervention and the final measure at 30 minutes post-intervention will be performed.

Primary Outcome Measures
NameTimeMethod
Change in lateral hip strengthPre-intervention, immediately following intervention, 15 min post-intervention & 30 min post-intervention

lateral isometric hip strength will be measured with Biodex system 4

Change in pain with double leg squatPre-intervention, immediately following intervention, 15 min post-intervention & 30 min post-intervention

Subject will provide level of anterior knee pain via Visual Analogue Scale (VAS) while performing a double leg squat.

The VAS pain scale is a 0 to 10 scale, 0 indicates no pain, 5 indicates distressing pain, 10 indicates unbearable pain. Any whole number between 0 and 10 may be chosen. 0 is better and 10 is worse.

Change in pain with drop jump from 2 foot platformPre-intervention, immediately following intervention, 15 min post-intervention & 30 min post-intervention

Subject will provide level of anterior knee pain via Visual Analogue Scale (VAS) while performing a drop jump from a 2 foot platform.

The VAS pain scale is a 0 to 10 scale, 0 indicates no pain, 5 indicates distressing pain, 10 indicates unbearable pain. Any whole number between 0 and 10 may be chosen. 0 is better and 10 is worse.

Change in pain with single leg step downPre-intervention, immediately following intervention, 15 min post-intervention & 30 min post-intervention

Subject will provide level of anterior knee pain via Visual Analogue Scale (VAS) while performing a single leg step down.

The VAS pain scale is a 0 to 10 scale, 0 indicates no pain, 5 indicates distressing pain, 10 indicates unbearable pain. Any whole number between 0 and 10 may be chosen. 0 is better and 10 is worse.
