Brief Summary

This study will be carried out to evaluate the effect of modified lumbar Sustained Natural Apophyseal Glide on low back pain in postnatal women.

Detailed Description

In fact, up to 75% of women who suffer from pregnancy-related back pain may continue to have pain after giving birth. Women who experience LBP or pelvic girdle pain (PGP) at 3 months postpartum were found to be at higher risk for persistent or chronic LBP. Of these women, only 6% recover within 6-18 months after giving birth.

A modified lumbar Sustained Natural Apophyseal Glide (SNAG) is an existing Mulligan mobilization technique performed with a combination of joint glide and physiological spinal movement. The glide can be applied to the spinous processes, facets, or unilaterally over the transverse processes while the patient performs the active exercise.

Few studies have been concerned with the effects of modified "SNAGS" on the lumbar spine . So, this study will be done to investigate its effect on low back pain in postnatal women aiming to improve their function to accomplish their daily living activities and reduce the side effects of medical treatment.

Primary Outcome Measures

Name	Time	Method
Pain intenesity	within 4 weeks	The visual analogue scale is a 10 cm calibrated line with 0 representing no pain and 10 representing the worst pain; will be used to assess the severity of pain before and after treatment for all participants in both groups.
Lumbar flexion range of motion	within 4 weeks	The modified Schober test will be used to measure the lumbar flexion range of motion (ROM) by using the tape measurement. Each participant will be asked to stand erect with her feet about shoulder-width apart to stabilize the pelvis. Then, the posterior superior iliac spines(PSIS) will be determined by the therapist's both thumbs, and then an ink line will be drawn along the midline of the lumbar spines horizontal to the PSIS to mark the midpoint between the two PSIS. Then tape will be used to identify and mark two points: one is 10 cm superior to the midpoint (A), and another is 5 cm inferior to the midpoint (B). The participant will be instructed to bend forward as much as she can while keeping both knees straight, the new distance between superior and inferior skin marking will be measured in centimeters. The increased distance along the tape due to lumbar flexion is normally about 6-7 cm (less than 5 cm should be considered abnormal).
Lumbar extension range of motion	within 4 weeks	The modified Schober test will be used to measure the lumbar extension range of motion (ROM) by using the tape measurement while the patient is in a standing position.; The participant will be instructed to put her hands on her buttocks and bend backward into full lumbar extension and the new distance between the superior and inferior skin markings will be measured in centimeters by the tape measurement. The change in the difference between the marks is used to indicate the amount of lumbar extension.; The increased distance along the tape due to the extension of the lumbar spine is normally about 2-3 cm (less than 1 cm should be considered abnormal).
Lumbar lateral flexion range of motion	within 4 weeks	The participant will be asked to stand erect with her feet about shoulder-width apart. Both right and left lateral flexion will be measured by the tape as the distance from the tip of the index finger to the floor at maximal comfortable lateral flexion. The participant will be instructed to bend her trunk laterally as much as she can. The normal value of lateral spinal flexion is 16.2-28.0 cm.

Secondary Outcome Measures

Name	Time	Method
Functional disability	within 4 weeks	Functional disability will be assessed by the Oswestry Disability Index, it was developed as a clinical valid and reliable assessment tool that would provide an estimate of disability expressed as a percentage score. It is composed of 10 questions and it takes around 5min for a patient to complete. Each of the 10 questions is scored from 0 to 5, giving a maximum score of 50. The total score is then converted into a percentage by multiplying it by 2. Scores are stratified into severity: 0-20, minimal disability; 21-40, moderate disability; 41-60, severe disability; 61-80, crippling back pain; 81-100, bed-bound. A low score = low degree of disability, a high score = high degree of disability.
