Summary

Lumbar disc herniation is a common musculoskeletal condition that negatively affects quality of life, physical function, and daily activities. Previous studies have shown that individuals with lumbar disc herniation often experience poor sleep quality, which is closely related to pain severity and functional limitations. In addition, a bidirectional relationship exists between chronic pain and sleep disturbances, where poor sleep can increase pain perception, and pain can further impair sleep.

Obstructive sleep apnea (OSA) is a common sleep-related breathing disorder associated with reduced sleep quality, daytime dysfunction, and adverse health outcomes. The STOP-Bang questionnaire (Snoring, Tiredness, Observed apnea, high blood Pressure, Body mass index, Age, Neck circumference, and Gender) is a widely used and practical screening tool to identify individuals at high risk for OSA in clinical settings.

Physiotherapy and rehabilitation programs are commonly used in the conservative management of lumbar disc herniation and have been shown to improve pain and functional outcomes. However, the effect of the timing of rehabilitation (daytime versus evening) on sleep-related outcomes has not been sufficiently investigated. Considering that circadian rhythms influence pain perception, physiological processes, and sleep regulation, the timing of rehabilitation interventions may play an important role in clinical outcomes.

Therefore, this randomized controlled trial aims to investigate the effects of daytime versus evening rehabilitation programs on sleep quality and daytime sleepiness in patients with lumbar disc herniation who are at high risk for obstructive sleep apnea.

  • Obstructive Sleep Apnea Risk Management

Interventions

BEHAVIORAL

Physiotherapy and Exercise Program

Participants will receive a standardized rehabilitation program consisting of electrotherapy modalities and therapeutic exercises. Electrotherapy includes hot pack application for 20 minutes, conventional TENS (60-100 Hz, 60 µs) applied at a comfortable sensory level for 20 minutes, and therapeutic ultrasound (1 MHz, 1.5 W/cm², continuous mode) for 5 minutes applied to the lumbar paravertebral region. The exercise program focuses on motor control and core stabilization targeting the transversus abdominis and multifidus muscles. Exercises will be progressively advanced from basic activation in supine position to functional stabilization tasks including bridging and quadruped exercises. Each session will last approximately 20 minutes and will be supervised by a physiotherapist. Electrotherapy will be applied 5 days per week, while the exercise program will be performed 3 days per week for a total of 15 sessions. The only difference between groups is the timing of the intervention.
