Texas Woman's University
  Purpose
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.

Condition Intervention
Patellofemoral Pain Syndrome Other: Lumbopelvic manipulation

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Effects of Lumbopelvic Manipulation on Hip and Knee Neuromuscular Activity in People With and Without Patellofemoral Pain Syndrome

Further study details as provided by Texas Woman's University:

Primary Outcome Measures:
  • Electromyography (EMG) [ Time Frame: 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. ]
    Electromyography (EMG) onset time of the gluteus maximus, gluteus medius, vastus medialis oblique, and vastus lateralis muscles.


Secondary Outcome Measures:
  • Pain Visual Analog Scale (VAS) [ Time Frame: 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. ]
    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".

Criteria

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:

  2. history of hip pathology or other knee condition
  3. current significant injury of any lower extremity joints
  4. pregnancy
  5. sign of nerve root compression
  6. osteoporosis or history of compression fracture

Age- and gender- matched control participants will be recruited if they have no signs or symptoms of patellofemoral pain syndrome and have none of the exclusion criteria
