Low back pain is common MSK disease with prevalence of 60 to 70 percent. Patients with low back discomfort are typically treated conservatively by physical therapists. Progressive muscles relaxation technique has been shown in several studies to reduce chronic back pain and increase flexibility. pressure biofeedback therapy works on Intra abdominal pressure.it helps to alleviate compression on lumbar spine and support the adjacent lumbar spine.The aim of this randomized controlled trial is to determine the effectiveness of pressure biofeedback training (Pr.BFB) in combination with progressive muscles relaxation technique (PMR) & progressive muscles relaxation training alone on pain, disability, ROM & endurance of muscles among nonspecific chronic low back pain patients.
A randomized clinical trial will be carried out in the Physical Therapy O.P.D of Dow hospital Karachi. Collection of data will commence right after approval of synopsis from Dow IRB. A sample of 70 NSCLBP patients calculated by using mean & SD of visual analogue scale in abdominal stabilisation training with Pr.BFB stabilizer was 2.69 ±0.93 and Progressive muscular Relaxation VAS was 3.863 ±2.03. Before being recruited into the experiment, patients will be screened to ensure that they meet the inclusion criteria. Pain rating scale and Roland-Morris questionnaire will be used to gather data after explaining the research goals to patients and obtaining formal consent from them. Patients will be divided into 2 interventional groups by simple random sampling, with 35 patients in each group. Experimental group will be received Pressure Bio-Feedback Therapy in combination with PMR Technique and Thermotherapy. The Control group, on the other hand, will be received a combination of Progressive Muscle Relaxation Technique and Thermotherapy for non-specific CLBP. It will be a 6-weeks intervention plan with 3 sessions per week (40-minutes each). Assessor will be blinded to the treatment. Roland Morris Low back pain and disability questionnaire (RMQ) and the NPR Scale will be used as primary outcome measures. Secondary outcomes will be determined by modified-modified Schober test for assessing lumbar ROM & Pressure Biofeedback Stabilizer unit helps to gauge muscular endurance.
