Brief Summary

The goal of this study is to train core muscles in patients with chronic low back pain, the researchers will compar between the effect of suspension exercise core muscle training and pressure biofeed back core muscle training

Conditions

Chronic Low-back Pain (cLBP)

Keywords

chronic low back pain; core muscles; pressure biofeedback training; suspension exercises

Outcome Measures

Primary Outcomes (2)

• change of low back pain

  Low back pain intensity will be measured using the Numeric Pain Rating Scale (NPRS). Participants will be instructed to select the number that best represents their current pain intensity. Scores range from 0 (no pain) to 10 (worst imaginable pain), with higher scores indicating greater pain severity.

  one month

• Change in Lumbar Extension Range of Motion

  Lumbar extension range of motion will be measured using the Modified-Modified Schober Test. Measurements will be recorded in centimeters (cm).

  one month

Secondary Outcomes (8)

• Change in Lumbar Flexion Range of Motion

  one month

• Change in Trunk Flexor Muscle Endurance

  one month

• Change in Trunk Extensor Muscle Endurance

  one month

• Change in Right Lateral Trunk Muscle Endurance

  one month

• Change in Left Lateral Trunk Muscle Endurance

  one month

Interventions

suspension execises BEHAVIORAL

Participants were instructed to perform the exercises through the full range of motion using the correct technique, while maintaining a neutral alignment of the spine and pelvis throughout each movement. Each exercise was performed three times, with each repetition lasting six seconds. A three-minute rest interval was provided between exercises to ensure adequate recovery, all exercises were performed three times per week for a duration of four weeks The following exercises have been selected 1. Roll-out 2. Bodysaw 3. Pike 4. Knee-tuck

suspension training group

pressure biofeedback training BEHAVIORAL

The patients were instructed to take a relaxed breath in and out, hold the breath out, and then draw in the lower abdomen without moving the spine. Independent contraction of the transversus abdominis muscle was achieved through the abdominal drawing-in maneuver(ADIM). * In the supine position, the pressure biofeedback unit was placed beneath the lumbar lordosis, and air was infused into the bulb to establish a baseline pressure of 40 mmHg. pressure increases of 0-2 mmHg g from a baseline of 40 mmHg * In the prone position, the pressure biofeedback unit was positioned between the navel and the anterior superior iliac spine (ASIS), and air was infused into the bulb to establish a baseline pressure of 70 mmHg. A decrease in pressure ranging from 4 to 10 mmHg during the performance of the active drawing-in maneuverwas considered to indicate a successful execution of the exercise. * After two weeks, lumbar stabilization exercises were progressively introduced

pressure biofeedback training group

advices BEHAVIORAL

1. Participants are instructed to walk as normally and flexibly as possible 2. Advise when lifting: * Participants are instructed to avoid twisting and bending. * When lifting heavy objects, they are instructed to use their thighs while keeping the back vertical. * At other times, they are instructed to use the back and flex it appropriately. 3. Participants were instructed to apply heat for 20 minutes, twice daily 4. Avoid sitting or standing for prolonged period and change position every 15 minutes. 5. Sitting: Sit with a back support 6. Driving: Use a back support (lumbar roll) at the curve of your back. 7. Participants were instructed to sleep and lie down on a firm mattress and box spring set that did not sag. If necessary, they were advised to place a board under the mattress or temporarily position the mattress on the floor.
