This study aims to investigate the effect of sensorimotor training on gait performance in patients with discogenic sciatica.
Discogenic sciatica is commonly associated with pain, functional limitations, and alterations in gait performance resulting from nerve root involvement and impaired neuromuscular control. Sensorimotor training is an active rehabilitation approach that integrates sensory input with motor responses and may improve proprioception, postural control, balance, and movement coordination. This study will investigate the additional effect of sensorimotor training in patients with chronic discogenic sciatica. Participants will receive a conventional physical therapy program consisting of interferential current therapy, hot packs, positioning according to directional preference, and static abdominal and back exercises. The experimental intervention will incorporate additional sensorimotor training, including proprioceptive neuromuscular facilitation (PNF)-based trunk exercises, balance training on unstable surfaces, colored-path sensorimotor exercises, and the Star Excursion Balance Exercise. The sensorimotor program will use progressive task-specific exercises designed to challenge proprioception, balance, trunk control, and neuromuscular coordination. Exercise difficulty will be gradually progressed according to participants' abilities through changes in surface stability, movement complexity, reach distance, walking speed, and the incorporation of dual-task activities. The study will evaluate changes in spatiotemporal gait parameters, pressure-pain threshold, and functional disability before and after the intervention. The findings may provide evidence regarding whether adding sensorimotor training to conventional physical therapy offers additional benefits for gait performance, pain-related outcomes, and functional ability in patients with chronic discogenic sciatica.

Standard physical therapy will include interferential current therapy applied over the lumbar region at 80-100 Hz for 15-20 minutes, hot packs applied over the lumbar paraspinal region for 10 minutes, positioning according to the patient's directional preference for 10 minutes or as tolerated, and static abdominal and back exercises targeting the transversus abdominis and multifidus. The exercises will be performed as 3 sets of 10 repetitions, with each contraction held for 10 seconds followed by 5 seconds of rest.
Sensorimotor training will include PNF-based trunk exercises, balance training on unstable surfaces, colored-path sensorimotor exercises, and the Star Excursion Balance Exercise. The program will incorporate progressive challenges to trunk control, balance, proprioception, and neuromuscular coordination. Progression will include unstable surfaces, alternating limb movements, single-leg and cross bridging, increased walking speed, dual-task activities, increased reach distance, and increased exercise complexity according to patient tolerance.

Walking Speed
Walking speed will be assessed using the FreeMed® baropodometric platform with FREESTEP software and reported in meters per second (m/s).
Time frame: 2 months
Stride Length
Stride length will be assessed using the FreeMed® baropodometric platform with FREESTEP software and reported in millimeters (mm).
Time frame: 2 months
Cadence
Cadence will be assessed using the FreeMed® baropodometric platform with FREESTEP software and reported as steps per minute (steps/min).
Time frame: 2 months
Stance Time
Stance time will be assessed using the FreeMed® baropodometric platform with FREESTEP software and reported in seconds (s).
Time frame: 2 months
Pressure-Pain Threshold
Pressure-pain threshold will be assessed using a pressure algometer at the lumbar paraspinal, gluteus medius, and piriformis muscles. Higher values indicate greater pressure-pain tolerance.
Time frame: 2 months
Functional Disability
Functional disability will be assessed using the Oswestry Disability Index (ODI). The score will be expressed as a percentage from 0% to 100%, with higher scores indicating greater disability.
Time frame: 2 months
