Effect of Passive Versus Active Aquatic Therapy Compared With Conventional Physiotherapy for Chronic Low Back Pain

Effect of Passive Versus Active Aquatic Therapy Over Conventional Physiotherapy in Patients With Chronic Low Back Pain - A Randomized Crossover Trial

This study is designed to help people with chronic low back pain, which is pain in the lower back that persists for more than three months and can affect daily life, including sitting, standing, walking, lifting, and other routine activities. Chronic low back pain can also impact work, mood, and overall quality of life, making it important to find effective rehabilitation methods that reduce pain and improve function.

The study compares the effects of three different rehabilitation approaches:

1. Active aquatic therapy - participants perform exercises in water where they actively move their back, core, and legs. The water helps support the body and reduces stress on the spine, allowing safer and easier movement. This approach aims to improve strength, flexibility, core stability, and overall function.
2. Passive aquatic therapy - participants receive assisted movements in water guided by a trained physiotherapist. This gentle method helps increase spinal mobility, reduces stiffness, promotes relaxation, and can relieve pain without placing stress on the lower back.
3. Conventional physiotherapy - participants perform standard exercises on land, including stretching, strengthening, and core stabilization exercises. All sessions are supervised by licensed physiotherapists to ensure exercises are done safely and effectively.

Participants will be randomly assigned to one of the three groups. Each intervention lasts 4 weeks, with multiple sessions each week. All sessions are supervised to provide proper guidance, ensure safety, and adapt exercises to each participant's needs.

Before starting therapy, participants' pain levels, core strength, flexibility, spinal mobility, and ability to perform daily activities will be measured using simple and understandable assessments. These measures will be repeated at the end of the 4-week intervention to evaluate improvements and compare the effectiveness of each rehabilitation approach.

The study is safe and non-invasive. No surgery, injections, or medications are involved. Participants' personal information is kept confidential, and all collected data will be used solely for research purposes.

By participating in this study, patients may benefit from structured, supervised rehabilitation that could help reduce pain, improve mobility and strength, enhance balance and core stability, and increase confidence in performing daily activities. Patients' feedback during sessions will also help researchers understand their experiences and preferences, which can improve future treatment recommendations.

The results of this study will help patients, families, physiotherapists, and healthcare providers understand which type of rehabilitation is most effective for chronic low back pain. This information can guide treatment decisions, improve individualized care plans, and support patients in returning to normal activities with less discomfort and greater independence.

Overall, the study aims to provide clear, practical information about rehabilitation options for chronic low back pain, improve functional outcomes, and enhance quality of life. Participants' contributions will help generate evidence that may benefit others with similar conditions in the future, while also receiving safe and professional care throughout the study.
