Background[edit | edit source]
The Active Straight Leg Raise (aSLR) is a test used to assess load transference through the pelvis. It is an important test in diagnosing Pelvic Girdle Pain (PGP).[1] The PGP could affect pregnant women, athletes with groin pain, or it can occours after a trauma.
For more information please see Recognising Pelvic Girdle Pain
Purpose[edit | edit source]
During testing, assessment of the primary subjective feature of heaviness of the leg is complimented by observation of motor control (MC) adaptations such as respiratory disruption and abdominal bracing[2]. Furthermore some studies[3] investigated the biomechanical models and their connection with lumbopelvic stability. support the hypothesis of aberrant MC patterns providing a mechanism for ongoing pain in specific PGP presentations
Technique[edit | edit source]
The ASLR consists of ipsilateral hip flexion, a contralateral hip extension moment, force closure by the lateral abdominal muscles, sagittal plane pelvis stabilization by the abdominal wall, and activity of contralateral transverse plane rotators of the pelvis. Problems with the ASLR may result from failing force closure. Other tests are available to confirm, or falsify, the clinical hypothesis that the patient is having problems with force closure.
