Inclusion criteria

Inclusion criteria: • Present with active gluteus medius trigger points that will be identified by flat palpation. The researcher will palpate for a taut, palpable band that elicits tenderness and possible referred pain. • Present with the following criteria associated with sacroiliac joint dysfunction: o sacroiliac joint motion restriction/s, as determined by motion palpation o altered end feel on motion palpation. • Be between the ages of 18 and 45 as degenerative changes are found in patients over 45.

Exclusion criteria

Exclusion criteria: • Any contraindications to spinal manipulative therapy as determined by case history, physical examination and lumbar spine regional examination. • Any lumbar spinal manipulation within the last 6 weeks. • Currently receiving any other treatments for low back pain, including pain control medication such as anti-inflammatories (NSAIDS) or muscle relaxants. Anti-inflammatory, analgesic and narcotic medications are used for symptomatic control. These medications would alter a patient’s perception of pain. • Any neurological dysfunction as determined by case history, physical examination and regional examination. • Making use of any post-treatment home therapies for the duration of the study.

Design outcomes

Primary

MeasureTime frame
The study will demonstrate a comparison between the two treatment modalities and identify whether one is more effective than the other in relieving active trigger points of the gluteus medius.

Secondary

MeasureTime frame
The study will also contribute to the link between joint dysfunction and myofascial trigger points and whether restoring normal joint function will effect the pressure pain threshold of myofascial trigger points.
