Brief Summary

This study is designed as a pre and post experimental study. The purposes of this study are to evaluate the effect of core muscles training in patients with chronic mechanical low back pain according to SALIBA'S postural classification system (SPCS) in terms of pain intensity, function, and core muscles endurance.

Conditions

Chronic Low-back Pain

Outcome Measures

Primary Outcomes (3)

• pain intensity.

  Pain intensity will be assessed using the visual analog scale (VAS). The VAS is a unidimensional measure of pain intensity. It is a continuous scale comprises of a horizontal line 10 cm in length. The scale is anchored by "no pain" (score of 0) and "worst imaginable pain" (score of 10). A higher score indicates greater pain intensity

  one month

• function disability

  Functional disability will be estimated using the cross-culturally adapted Arabic version of the Oswestry disability questionnaire.The score is calculated by the addition of the values assigned for each of the 10 individual questions and is used to categorize disability as: mild or no disability (0- 20%); moderate disability (21%-40%); severe disability (41% to 60%); incapacity (61% to 80%); restricted to bed (81% to 100%).

  one month

• core muscles endurance

  The researcher will conduct a series of core stability tests before and after the core training program. The following core tests will be used: trunk flexion test (McGill's test) , Trunk extension (Sorenson Test, Right Side plank test,left side plank and prone plank test. We will record the time (in seconds) the patient can hold the isometric posture, with a normal range of 1-2 minutes

  one month

Other Outcomes (1)

• participants gender will be male and females, their age in years,their height in meters,weight in kilograms.

  one month

Study Arms (6)

group1: vertical/ vertical

EXPERIMENTAL

participant posture: The thoracic block is vertically aligned over the pelvic block.The angle of the thoracic block is vertical in the sagittal plane allowing for the dome of the diaphragm to rest on top of the abdomen.Vertical force transfers through the musculoskeletal system through the mid-foot and into the standing surface causing no shifts in postural alignment.

Other: core muscles training exercises

group 2: vertical/ posterior

EXPERIMENTAL

participant posture: The thoracic block is vertically aligned over the pelvic block but is posteriorly tipped in the sagittal plane.Vertical force leads to an accentuated extension in the thoracolumbar and lumbar regions with decreased ability to sustain vertical forces.

Other: core muscles training exercises

group 3: posterior/ posterior

EXPERIMENTAL

participant posture: The thoracic block is aligned posterior to the pelvic block and is posteriorly tipped in the sagittal plane. Vertical force leads to an accentuated extension in the lower lumbar region with a forward shear of the pelvis and decreased ability to sustain vertical forces.

Other: core muscles training exercises

group 4: posterior/ anterior

EXPERIMENTAL

participant posture: The thoracic block is aligned posterior to the pelvic block and is anteriorly tipped in the sagittal plane. Vertical force leads to a slight flexion in the thoracic and lumbar regions with a forward shear of the pelvis and decreased ability to sustain vertical force.

Other: core muscles training exercises

group 5:anterior/ posterior

EXPERIMENTAL

participant posture: The thoracic block is aligned anterior to the pelvic block and is posteriorly tipped in the sagittal plane. Vertical force leads to extension in the mid and lower lumbar regions with a posterior shear of the pelvis and decreased ability to sustain vertical forces.

Other: core muscles training exercises

group 6: anterior/ anterior

EXPERIMENTAL

participant posture: The thoracic block is aligned anterior to the pelvic block and is anteriorly tipped in the sagittal plane. Vertical force leads to an overall flexion of the trunk and decreased ability to sustain vertical forces

Other: core muscles training exercises

Interventions

core muscles training exercises OTHER

The sessions will be conducted three times per week for four weeks and each exercise will be performed two sets of 10 repetitions. For the static exercises, the final position will be held for 6 second. There will be a pause of 3 second between repetitions, and a 60 sec rest between each exercise. The exercise will be performed in three forms: abdominal bracing, dynamic stabilization, and advanced core strengthening.

group 2: vertical/ posterior; group 3: posterior/ posterior; group 4: posterior/ anterior; group 5:anterior/ posterior; group 6: anterior/ anterior; group1: vertical/ vertical
