Effect of Diaphragm Manual Therapy With Conventional Physical Therapy in Chronic Non-Specific Low Back Pain Patients

Study Overview
=================
Brief Summary
-----------------
A randomized single-blind clinical study will be performed. A sample size of 34 patients including only male gender, will be taken from various clinical settings of Faisalabad. Non-probability purposive sampling technique will be used. Patients will be randomly allocated into two groups. Treatment Group A will perform Conventional Physical Therapy and Diaphragm Manual Therapy and Group B will perform Conventional Physical Therapy and Sham Diaphragm Manual Therapy. Numerical Pain Rating Scale and lumbar range of motion scores will be assessed at pre-treatment, 2nd-week post-treatment and 4th-week post-treatment. Oswestry Disability Index scores and Short Form 12 Health Survey Questionnaire will be assessed at pre-treatment and 4th-week post-treatment. Statistical analysis will be performed on Statistical Package for the Social Sciences Version 25.

Detailed Description
-----------------
Over 80% of people experience Lower back pain in their lives, of which 23% suffer from chronic pain. Physiotherapists use multiple treatment options for treating non-specific chronic low back pain such as joint mobilization, therapeutic exercises, electrotherapeutic modalities and soft tissue release techniques. The objective of the study is to determine the effect of conventional physical therapy with or without diaphragm manual therapy in patients with chronic non-specific low back pain. A randomized, single-blind clinical study will be performed. A sample size of 34 patients comprising of only male gender will be taken from various clinical settings of Faisalabad. Non-probability purposive sampling technique will be used. Patients will be randomly allocated into two groups. Treatment Group A will perform Conventional Physical Therapy and Diaphragm Manual Therapy and Group B will perform Conventional Physical Therapy and Sham Diaphragm Manual Therapy. Numerical Pain Rating Scale and lumbar range of motion scores will be assessed at pre-treatment, 2nd-week post-treatment and 4th-week post-treatment. Oswestry Disability Index scores and Short Form 12 Health Survey Questionnaire will be assessed at pre-treatment and 4th-week post-treatment. Statistical analysis will be performed on Statistical Package for the Social Sciences Version 25. Mean ± Standard Deviation will be used to present Quantitative variables while Qualitative variables will be shown through frequency tables and percentages will be shown in the form of frequency tables and percentages. Summary of group measurements will be represented through Graphs. Normal distribution of data will be analyzed through skewness, kurtosis and Shapiro wilk test. If data is found normally distributed, then parametric tests will be applied, which will include an Independent sample t-test for measuring inter-group changes. Paired Sample t-test/Repeated measure ANOVA for measuring intra-group differences. If data is found non-normally distributed, then non-parametric tests will be applied, which will include Mann-Whitney U-Test for measuring inter-group changes and Wilcoxon Test/Friedman Test for measuring intra-group differences. P-value ≤ 0.05 will be taken as significant.

Design Details

Primary Purpose: Treatment
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Group A<br>Group A will receive Manual Diaphragm Technique in addition to Conventional Physical Therapy. Treatment will be provided for a total of four weeks, thrice a week. | Other: Manual Diaphragm Technique<br>* Treatment group will receive Manual Diaphragm Technique in addition to Conventional Physical Therapy. Therapist will make physical contact to the underside of the 7th to 10th rib costal cartilages. During the inspiratory phase, the therapist will use both hands to gently pull the points of contact in the direction of the head. During exhalation, the therapist will maintain resistance. The procedure will be done in two sets of ten deep breaths, separated by a one-minute pause.<br>Other: Conventional Physical Therapy<br>* Conventional Physical Therapy group comprises electrotherapeutic treatment and exercise plan. Subjects will undergo a thermal continuous ultrasound, conventional transcutaneous electrical nerve stimulation and a hot pack. Stretching activities for the back, iliopsoas, and hamstring muscles, as well as abdominal muscle strengthening exercises, will be included in the workout.<br>|
| Active Comparator: Group B<br>Group B will receive Conventional Physical Therapy and Sham Diaphragm Technique. Conventional Physical Therapy group comprises electrotherapeutic treatment and exercise plan. Treatment will be provided for a total of four weeks, thrice a week. | Other: Conventional Physical Therapy<br>* Conventional Physical Therapy group comprises electrotherapeutic treatment and exercise plan. Subjects will undergo a thermal continuous ultrasound, conventional transcutaneous electrical nerve stimulation and a hot pack. Stretching activities for the back, iliopsoas, and hamstring muscles, as well as abdominal muscle strengthening exercises, will be included in the workout.<br>Other: Sham Diaphragm Manual Technique<br>* The Control group will also receive a sham diaphragm release technique. The therapist and participant will have the same manual contacts, duration, and placement as the treatment group, but the therapist will simply use a light touch with the same anatomical landmarks and will not apply pressure.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Numerical Pain Rating Scale (Pain) | Numerical Pain Rating Scale will be used to measure back pain. Score of scale ranges from 0 (no pain) to 10 (worst possible pain). | Change from baseline at 2nd week and Change from 2nd week at 4th week. | 
| Change in Universal Goniometer (Lumbar Range of Motion) | Universal Goniometer will be used to measure Lumbar Range of Motion. | Change from baseline at 2nd week and Change from 2nd week at 4th week. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
