简要总结
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).
详细描述
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.

盲法说明
Double Blind: The subjects will not know what intervention they are receiving - same generic script is provided. One Investigator is performing all pre and post-tests without knowledge of intervention, the other investigator is opening the envelope and providing the intervention behind a screen without knowledge of test results. This investigator will record the subjects assigned # and which intervention they received. Investigators will record data on spreadsheet separately.
The outcomes will be evaluated by a masked outcome assessor.

研究组 & 干预措施
Lumbar thrust-mobilization
The investigator will perform a lumbar thrust-mobilization with the subject in right and then left sidelying position
干预措施: Lumbar-thrust mobilization (Other)
Sham-mobilization
No lumbar-thrust mobilization will be performed. Subject will receive simple passive inter-vertebral range of motion.
干预措施: Sham thrust-mobilization (Other)
结局指标
主要结局
Change in lateral hip strength
时间窗: Pre-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 squat
时间窗: Pre-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 platform
时间窗: Pre-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 down
时间窗: Pre-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.
