Radiculopathy or nerve root pain arises from disc herniation, spinal stenosis/post-operative scarring, radiating down the leg in a dermatomal pattern. Lumbosacral radiculopathy is defined as a "disarticulation of disc components nucleus pulpous or annulus fibrosis beyond the intervertebral disc space. Low back pain (LBP) is one of the most widely recognized conditions that debilitate people's functional capacity in activities of daily living and at work, as well as their general wellbeing and quality of life.

Pain between the buttock and lower edge of the ribs is referred to as low back pain, and it can be classified as acute, sub-acute, or chronic depending on how long it lasts. Acute pain lasts less than four weeks, sub-acute pain lasts more than four but less than twelve weeks and if pain lasts for more than 12 weeks it is chronic LBP. The prevalence of chronic low back pain is steadily rising in today's aging population. Around 80% of the population experience spinal pain sooner or later in life.. The intervertebral disc absorbs physical shock to the backbone; it is composed of two dissimilar tissue layers, an inner layer called the nucleus pulposus and an external layer called the annulus fibrosis. Muscle spasm refers to sustained contraction of a muscle and the increase in chronic tension contributes to pain.

This study is necessary because chronic lumbar radiculopathy often leads to a contralateral lateral shift, causing pain and functional limitations. Traditional physical therapy (TPT) provides general rehabilitation but may not specifically correct this shift. The McKenzie technique (MDT) focuses on self-correction, centralization of symptoms, and postural realignment, making it a potentially superior treatment. However, limited research directly compares McKenzie therapy with TPT for lateral shift correction. This study aims to fill this gap, guiding clinicians toward the most effective rehabilitation approach, improving patient outcomes, and optimizing treatment protocols.• To evaluate the effectiveness of Mackenzie technique versus traditional physical therapy in correcting the lateral shift in patients with chronic lumber radiculopathy.
