Efficacy of Adding LLL Therapy to Postural Correction Exercises on Postnatal SIJ Pain

Study Overview
=================
Brief Summary
-----------------
the purpose of the study will be to to examine the effect of low level laser therapy on pain and function disability in postnatal women with sacroiliac joint pain.

Detailed Description
-----------------
Women are more susceptible to sacroiliac joint pain than men because the physiological changes associated with childbearing (e.g. pregnancy associated with weight gain, exaggerated lumber lordosis, hormone-induced ligamentous laxity and the mechanical trauma associated with childbirth) may result in sacroiliac joint pathology . Low level laser is effective for treatment of various musculoskeletal pain disorders. It releases local neurotransmitters such as serotonin and endorphins. Additionally, the analgesic effect of LLLT is thought to be related to its anti-inflammatory action. Laser irradiations also relieve pain by alleviating and removing swelling and by increasing oxygenation of the tissues, thus results in reduction of the pain .

Eligibility Criteria
-----------------
Inclusion Criteria: Post natal women suffering from sacroiliac joint pain for at least 3 months. They should have moderate to severe pain in the sacroiliac joint region (visual analogue scale ≥ 4). They should have positive findings in at least three of five provocation sacroiliac joint tests (i.e., Patrick's sign, Gaenslen test, compression test, thigh thrust test and distraction test). Their age will range from 25 to 40 years old. Their Body mass index (BMI) will be ranged from 25 to 30 Kg /m2. They should not have any musculoskeletal disorders. Exclusion Criteria: Lumber or hip joint pathology. Acute pelvic bacterial or viral infections or tumour. Taking nonsteroidal anti-inflammatory drugs, or hormonal treatments. Having positive straight leg raising test.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| pain intensity | The pain intensity will be assessed through visual analogue scale (VAS) for both groups before and after the end of treatment program. Each woman will be asked to mark a point on the line between the extremes that related to her pain intensity. | up to 2 months | 
| pain pressure threshold | pressure algometer will be used to assess pain pressure threshold for both groups before and at the end of the study | up to 2 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| functional disability | oswestery disability index will be used to assess level of functional disability for both groups before and at the end of the study | up to 2 months |
