Effect of Sciatic Nerve Neurodynamic Sliding on Pain, Disability, and Balance in Patients With Lumbar Radiculopathy

Inclusion Criteria: * Chronic unilateral lumbar painful radiculopathy (duration ranged from 3 to 18 months). * During the evaluation session, repeated lumbar movements did not improve or worsen lower extremity symptoms. * Positive straight leg raise (SLR) response. A positive SLR test was defined as the presence of both of these findings: (1) the test reproduced the patient's symptoms and (2) the symptoms decreased with the ankle plantar flexion component of the test. * Unilateral Pain radiating below the knee, with leg pain equal to or more severe than the accompanying back pain. * The presence of paresthesia such as pins and needles or numbness in the affected limb, along with neurological deficits-whether motor, sensory, or reflex-that corresponded to the dermatome or myotome of the affected nerve root. Exclusion Criteria: * Systemic diseases such as autoimmune and metabolic diseases. * Previous Lumbar Spine surgery. * Lumbar spine stenosis. * Spinal deformity. * Spinal fracture. * Bilateral lower extremity symptoms. * Steroid injection or use of anti-inflammatory medications within two to four weeks prior to study commencement.
