Purposes of the study

To investigate the effect of Multimodal Physical Therapy on pain, daiablility H-reflex, and Diffusion Tensor Imaging (DTI) Parameters in Patients With Lumbosacral Radiculopathy.

Participants will receive Multimodal Physical Therapy program consisting of electrophysical agents, manual therapy interventions, and core stability exercises. Patients will receive the intervention for six weeks. Outcomes will be assessed at baseline and post-intervention.

Inclusion Criteria:

• chronic (≥ 3 months) unilateral Lumbosacral Radiculopathy (LSR)
• The LSR is due to paracentral L4-L5 or L5-S1 Lumbar disc herniation
• The LSR is confirmed radiologically by MRI
• The LSR is confirmed clinically by history and physical examination
• The LSR is confirmed neurophysiological by soleus H-reflex assessment
• Body mass Index less than 30
• 20-45 years of age

Exclusion Criteria:

• systematic disease
• Bilateral symptoms
• Lumbar spinal stenosis
• previous surgery
• Steroid injection
• Spinal fracture
• Lumbar spinal stenosis
• Spinal deformity
• Spinal fracture
• Radiological evidence of bilateral nerve root encroachmen
• Evidence of H-reflex amplitude or latency affection on asymptomatic side
