Clinical Trial Summary

The purpose of this study is to determined if a lower back treatment would change the hip and knee muscle activities in people with and without anterior knee pain. The investigators hypothesized that the lower back treatment may change the hip and knee muscle activities in people with anterior knee pain but not in people without anterior knee pain.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Electromyography (EMG)	Electromyography (EMG) onset time of the gluteus maximus, gluteus medius, vastus medialis oblique, and vastus lateralis muscles.	The EMG data will be collected within 48 hours for all participants in both groups. On Day 1, data will be collected twice at baseline. On Day 2, data will be collected before and immediately after as well as 15, 30, and 45 min after the intervention.	No
Secondary	Pain Visual Analog Scale (VAS)	Pain Visual Analog Scale (VAS) is a 100 mm continuous line between two end-points. The left end-point represents "no pain" and the right end-point represents the "worst pain imaginable".	The Pain Visual Analog Scale (VAS) will be assessed before and 45 min after the lower back treatment (lumbopelvic manipulation) for participants in the patellofemoral pain syndrome group on Day 2 only.	No
