Will individual participant data (IPD) be shared publicly (including data dictionaries)?  

Response - NO

Patients will be recruited from New OPD, Department of Physical Medicine and Rehabilitation, PGIMER Chandigarh. Patients will be thoroughly explained about the study and given a patient information sheet before participation. Then, they will be asked to sign a written informed consent and assent form.   Patient screening will be done as per inclusion and exclusion criteria. All the subjects will undergo a complete musculoskeletal evaluation, and patients will be enrolled as per their eligibility criteria. All the patients will be evaluated for the undermentioned parameters using a numerical pain rating scale, which will be used to assess both lower back and leg pain. Muscle flexibility and range of motion will be evaluated by finger-tip to floor measurements in centimeters, and functional performance will be evaluated using the Modified Oswestry disability index and Roland Morris disability questionnaire.  Patients will be randomly allocated to either of the two groups Interventional group and the Control group. Patients in both groups will be directed to physical therapy five times weekly. The control group will receive conventional physical therapy protocol including stretching manoeuvers for tightened muscles such as the piriformis, hip flexors, hamstring, and thoracolumbar fascia, depending on their level of muscle stiffness, William’s flexion exercises and Lumbar stabilization exercises under our supervision at the physiotherapy section, New OPD, PGIMER Chandigarh. The interventional group will receive lumbar anteroposterior mobilizations followed by conventional physical therapy protocol, including stretching manoeuvers, William’s flexion exercises, and lumbar stabilization exercises under our supervision at the physiotherapy section, New OPD, PGIMER Chandigarh. Both groups will also be advised to use moist heat at home. They will also be advised to follow back care, which includes avoidance of all activities and exercises involving the lumbar spinal extension of the spine. A lumbosacral brace in anti-lordotic posture during traveling and exertion will be recommended. Postural awareness will be given to maintain normal posture. All outcome measurements, Numerical pain rating scale for both lower back and leg pain, muscle flexibility and Range of motion using finger-tip-to-floor distance measurements in centimeters, and functional performance using Oswestry disability index questionnaire, Roland Morris disability questionnaire. This will be noted at baseline, 2nd week of exercise, and 4th week of the physical therapy program.

Statistics: Descriptive data will be calculated as mean and standard deviation. The level of significance of the tests will be considered by p < 0.05 with a 95% confidence interval (CI). The normality of the data will further be determined through the formal tests. Moreover, inter-group comparisons and non-normal cases will be examined via independent T-test and Mann–Whitney U test, respectively. A paired T-test and Wilcoxon signed-rank test will be employed for intra-group comparisons as per the normality of the data.
