Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: McKenzie Therapy
Other: McKenzie Exercises

Prone on Elbows: The patient was lie on their stomach with their elbows positioned under the shoulders, allowing them to rest on their forearms. This position hold for 15 seconds, with the patient instructed to take deep breaths and relax. This exercise repeated 10 times to enhance spinal extension and relieve pressure.

Prone Press-Ups: In this exercise, the patient was prone line and hands placed under shoulders. They gradually straighten their elbows, lifting the upper body within a pain-free range. Each press-up was held for 15 seconds and repeated 10 times, aiming to promote spinal extension and alleviate pain.

Extension in Standing: The patient was stand in a balanced position and lean backward as far as possible, allowing their head to tip back, then return to a neutral stance. This extension was held for 15 seconds and repeated 10 times, with the goal of improving lumbar mobility and centralizing pain.

Three sessions per week were continued for 8 weeks.

Other: Conventional Physical Therapy

Mulligan Mobilization: For Mulligan mobilization, the patient assumed a prone position. A posterior-to-anterior glide was applied to the sacroiliac joint in three sets of 10 repetitions. The patient was instructed to extend the leg simultaneously with the glide, helping to realign the joint and reduce discomfort by promoting proper joint movement.

Hot Therapy: Heat therapy was administered to the lower back and sacroiliac joint (SIJ) area for 10 minutes to improve blood flow, reduce stiffness, and prepare tissues for further interventions.

Transcutaneous Electrical Nerve Stimulation (TENS): TENS was applied as an analgesic modality. In the prone position, the patient underwent TENS therapy for 20 minutes at a frequency of 20-50 Hz. Two electrodes placed on the primary painful area, while the other two was be positioned along the path of the radiating nerve to help reduce pain and promote muscle relaxation.

Other: William Exercises
William exercises was performed to strengthen up the abdominal and gluteal musculature in an effort to manage the sacroiliac joint pain. In this pelvic tilt exercise, Single knee to Chest exercise, Double knee to Chest exercises and hamstring stretching was performed 3 sets of each exercise with hold for 8 to 10 sec and 10 repetitions each set was performed for three times a week. This was continued for 8 weeks.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Numeric Pain Rating Scale (NPRS)
Time Frame: From enrollment to the end of treatment at 8 weeks.
NPRS is a simple tool which is used to assess intensity of pain. Patients have to rate their pain level on NPRS scale from 0 to 10. It provides a quick, quantifiable measure of pain, aiding healthcare providers in monitoring treatment efficacy and adjusting interventions accordingly.
From enrollment to the end of treatment at 8 weeks.
Oswestry Disability Index (ODI)
Time Frame: From enrollment to the end of treatment at 8 weeks.
ODI is a widely known as questionnaire designed to measure the level of disability in patients with lower back pain. Comprising 10 sections, each focusing on daily activities such as pain intensity, personal care, lifting, walking, sitting, standing, sleeping, social life, traveling, and employment, the ODI assesses the impact of pain on functional abilities. Each section is scored from 0 to 5, with higher scores indicating greater disability. Summing the scores provides a percentage-based measure of disability, ranging from minimal to severe. The ODI is instrumental in clinical practice for evaluating treatment effectiveness and monitoring patient progress over time.
From enrollment to the end of treatment at 8 weeks.
Short form-36 for Quality of Life (SF-36)
Time Frame: From enrollment to the end of treatment at 8 weeks.
SF-36 is a 36-question survey that looks at health-related quality of life in eight areas: physical functioning, role limitations due to physical and mental health, pain in the body, general health perceptions, vitality, social functioning, health. SF-36 is a common tool used in research and clinical settings to measure how diseases affect people, how treatments help people, and how well people are overall. It shows many different aspects of a patient's quality of life. Get a clear picture of both your physical and mental health by scoring each domain. This is useful for both initial tests and keeping an eye on changes in health over time.
From enrollment to the end of treatment at 8 weeks.
