This randomized controlled trial aims to compare the effectiveness of elastic resistance training and free weight training in strengthening the gluteus medius muscle among patients with chronic non-specific low back pain. Weakness in the gluteus medius can contribute to pelvic instability and altered gait patterns, which may exacerbate low back pain. While both elastic resistance and free weight exercises are commonly used in rehabilitation, there is limited evidence comparing their relative benefits in this population. This study evaluates improvements in pain, muscle strength, and overall gait speed following each intervention. The findings will help guide clinicians in choosing the most effective and accessible strengthening method for patients with chronic non-specific low back pain.
The gluteus medius plays a vital role in pelvic stabilization and maintaining proper gait mechanics. Dysfunction or weakness in this muscle is frequently associated with chronic non-specific low back pain, a condition affecting a significant proportion of the population. Rehabilitation strategies that target the gluteus medius are crucial for restoring lumbar-pelvic stability, optimizing functional movement, and reducing pain. Free weight training, using equipment like dumbbells and barbells, is a traditional method to enhance muscle strength and improve neuromuscular coordination. However, it often requires proper supervision to avoid injury due to the need for controlled movements and joint stability. On the other hand, elastic resistance training, which employs tools like resistance bands or tubes, offers a safer, cost-effective, and portable alternative. It allows progressive resistance throughout the range of motion, matching the user's strength curve and facilitating home-based exercise programs. This randomized controlled trial is designed to compare these two training modalities, which are elastic resistance versus free weights in terms of their effectiveness at improving gluteus medius strength, reducing low back pain, and enhancing gait speed in patients with chronic non-specific low back pain. The trial includes baseline and post-intervention assessments using validated clinical tools for measuring pain, strength, and gait speed. The goal is to determine which intervention yields greater clinical benefit and offers a more practical approach for implementation in therapeutic settings, especially for populations with limited access to conventional gym equipment. The findings could contribute valuable evidence to inform clinical decision-making in physical therapy and rehabilitation.

Change in Pain Intensity
Pain will be assessed using the Numeric Pain Rating Scale (NPRS), a self-reported 11-point scale ranging from 0 (no pain) to 10 (worst imaginable pain).
Time frame: Baseline and at 4 weeks post-intervention
Change in Gluteus Medius Muscle Strength
Muscle strength will be measured using a manual muscle testing to assess isometric strength of the gluteus medius. A system of manually testing weakness of muscles by assuming different positions and performing movements against gravity or gravity eliminated depending on the strength of the and 5 indicates the muscle can hold anti-gravity position against maximum resistance.
Time frame: Baseline and at 4 weeks post-intervention
Change in Overall Gait Speed
Gait speed will be measured using the 10-Meter Walk Test (10MWT), recorded in meters per second (m/s).
Time frame: Baseline and at 4 weeks post-intervention
