Effects of Lumbopelvic Manipulation on Hip and Knee Neuromuscular Activity

Effects of Lumbopelvic Manipulation on Hip and Knee Neuromuscular Activity in People With and Without Patellofemoral Pain Syndrome

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.

Description

Inclusion Criteria for participants in the patellofemoral pain syndrome group:

1. insidious onset of symptoms of non-traumatic origin
2. pain with patellar facet palpation or compression

3. subjective knee pain rating of at least 3/10 on the pain visual analog scale during at least one of the following activities:

   • ascending stair
   • descending stair
   • kneeling
   • squatting
   • running
   • jumping
   • prolong sitting for more than 20 minutes

Exclusion criteria for all participants:

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Patellofemoral Pain Syndrome; Participants with Patellofemoral Pain Syndrome	Other: Lumbopelvic manipulation; High-velocity-low-amplitude thrust manipulation of the lumbopelvic region

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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.
