Effects of Lumbopelvic Manipulation on Hip and Knee Neuromuscular Activity

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.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

for participants in the patellofemoral pain syndrome group:

  • insidious onset of symptoms of non-traumatic origin
  • pain with patellar facet palpation or compression
  • 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:

  • history of spine, hip or knee surgery
  • history of hip pathology or other knee condition
  • current significant injury of any lower extremity joints
  • pregnancy
  • sign of nerve root compression
  • 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

Treatment and study plan

Lumbopelvic manipulation

Other

High-velocity-low-amplitude thrust manipulation of the lumbopelvic region

Primary outcomes

  1. 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 outcomes

  1. 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".
