Summary

Randomized control trial to examine the immediate effect of isometric exercise on pressure pain threshold (PPT) in adults with chronic low back pain. The secondary aim of this study was to investigate the acute effects of isometric exercise on clinical pain intensity.

Detailed description

Participants will attend a single visit to the hospital for two hours, which will include collecting demographic details and clinical characteristics through self-reported assessment scales. After that, outcome measures (pain sensitivity and current low back pain intensity) were collected prior to the intervention and repeated immediately post-intervention.

Conditions

• Chronic Low Back Pain (CLBP)

Interventions

Type	Name	Description
OTHER	Multiple repetition isometric wall squat	Participants were directed to rest their backs against the wall with shoulder width apart and feet parallel, then descend until they achieve an angle of 100 degrees at knee joint. The knee joint angle was assessed using a goniometer placed on the lateral epicondyle of the knee, aligned with the femur, while the anchor arm was aligned with the lateral malleolus. They were instructed to maintain the isometric hold for up to three minutes, or until volitional fatigue was reached.with a 30-second rest period between each squat hold.
OTHER	Multiple Isometric wall squat exercise + Double Leg Lower with Isometric Hold	Participants were directed to rest their backs against the wall with shoulder width apart and feet parallel, then descend until they achieve an angle of 100 degrees at knee joint. The knee joint angle was assessed using a goniometer placed on the lateral epicondyle of the knee, aligned with the femur, while the anchor arm was aligned with the lateral malleolus. They were instructed to maintain the isometric hold for up to three minutes, or until volitional fatigue was reached.with a 30-second rest period between each squat hold. Immediately post 60 second rest, Determine the participant's maximum angle using the double leg lowering test from supine position let the participant with both legs straightened before lifting the posterior hip, lowering the legs to a specific angle. Turn on the stopwatch. Hold the position near--maximally, try to achieve on (IES=9/10) and hold for the longest duration. They should reach 4 minutes for 3 repetition with 30 seconds rest between repetition
OTHER	Control quiet seated rest	The control group served as the control group and did not perform any exercise. Participants were instructed to sit quietly in a standard height stationary clinical room patient chair for the entire eight minutes.
