Brief Summary:
The purpose of this study was to evaluate the effects of stabilization exercises on pain, disability and pelvic floor muscles function in patients with lumbopelvic pain.

Condition or disease Intervention/treatment Phase
Postpartum Lumbopelvic Pain Other: Stabilization exercise Other: Control group Not Applicable

Detailed Description:

Pregnancy is a specific experience that leads to several physical changes in women's body and influence most aspects of their lives. Pregnancy and delivery can cause serious complications such as urinary incontinence, pelvic organ prolapse, fecal incontinence, and low back pain (LBP) that have negative effects on women's sexual, physical, social and psychological health.

Based on Wu et al. systematic review, prevalence of pregnancy related low back pain (PLBP) during pregnancy and postpartum is 45% and 25% respectively.

LBP is one of the most current causes of disability and sick leave after delivery.Abnormal load transfer in the lumbopelvic region has been considered as one possible explanation to lumbopelvic pain.The local stabilizing muscles, i.e. the transversely oriented abdominal, diaphragm, the lumbar MF and the PFM Play an important role in load transfer in the lumbopelvic, we considered that an exercise program that addresses muscular dysfunction, such as lumbar stabilization exercise can improve motor pattern of local stabilizing muscles and can use in management of postpartum lumbopelvic pain.

Arm Intervention/treatment
Experimental: stabilization exercises
stabilization exercises for 6 weeks, 3 sessions per week and each session was 40 minutes for the training group.
Other: Stabilization exercise
18 sessions during 6 consecutive weeks, three times per week, 30 or 40 minutes per session including: Twenty minutes for receiving hot pack and TENS and 10 or 20 minutes for training the exercises in 7 level : 1.Train the specific contraction of the deep abdominal muscles, multifidus and pelvic floor muscles(PFM). 2.Train the specific contraction of deep abdominal muscles with coactivation of multifidus and PFM in supine, prone, sitting, standing and quadruped position. 3. Segmental control exercises in close kinematic chain. 4. Segmental control exercises in open kinematic chain with limb loading, emphasis on abdominal muscles. 5. Segmental control exercises in open kinematic chain with limb loading, emphasis on back extensor muscles. 6. Progress exercises to functional task. 7. Coactivation of abdominal and multifidus muscles with limb loading in aerobic tasks.

Experimental: control group
electrotherapy include of 20 minutes TENS conventional and Ultrasound pulse for 10 minutes without any exercises for the control group.
Other: Control group
8 sessions during 6 consecutive weeks, three times per week, per session including: Twenty minutes for receiving hot pack and TENS
