• Conditions: Low Back Pain

• Registration Number: NCT06859645
• Lead Sponsor: Istanbul Bilgi University

Brief Summary

Low back pain is a significant global health issue, affecting a large proportion of the population at some point in their lives. Among the different types of low back pain, non-specific low back pain is the most common. Chronic low back pain has been shown to impact trunk endurance, functional capacity, fatigue, anxiety, and depression levels.

Neuroscience-based studies aimed at improving pain management have demonstrated that chronic pain is associated with not only peripheral changes but also central changes. These central changes include abnormalities in the distribution of sensory cortical processing, disinhibition of the motor cortex, and disturbances in body schema perception.

Studies have shown that motor imagery training, defined as the mental simulation of movement without actual execution, functions as a cortical-level training method and has positive effects on impaired body schema perception, thereby reducing pain. A review of the literature indicates that motor imagery training contributes to the treatment of pathological pain syndromes such as complex regional pain syndrome, brachial plexus avulsion injury, phantom limb pain, distal radius fracture, and stroke by modulating cortical mechanisms. However, no randomized controlled trials have investigated the effectiveness of adding motor imagery training to exercise therapy in individuals with non-specific chronic low back pain, specifically regarding its impact on physical function and psychosocial parameters.

The aim of this study is to investigate the effects of a motor imagery training protocol, applied in addition to exercise therapy, on pain, physical, and psychosocial parameters in individuals with non-specific chronic low back pain.

A total of 32 individuals with chronic non-specific low back pain will be included in the study. Participants will be randomly assigned to either the intervention or control group. All participants will receive telerehabilitation-based exercise therapy under the supervision of a physiotherapist. In addition to the exercise therapy, participants in the intervention group will undergo asynchronous motor imagery training every day for eight weeks, while the control group will receive only exercise therapy.

Assessments will be conducted three times: before treatment, at the end of the 8-week intervention, and at the 12th week follow-up. All assessments will be performed through a telerehabilitation-based approach. The study will evaluate participants' pain, fatigue, disability level due to low back pain, anxiety and depression levels, and physical function.

Primary Outcome Measures

Name	Time	Method
Numeric Pain Scale	Baseline, at 8 week, at 12 week	The severity of general low back pain experienced by the participants in the last two days will be assessed numerically using the Numeric Pain Scale. Participants will be informed that a score of 0 represents "no pain at all," while a score of 10 represents "the most unbearable pain." Pain severity will be recorded numerically on a scale from 0 to 10.

Secondary Outcome Measures

Name	Time	Method
Oswestry Disability Index	Baseline, at 8 week, at 12 week	The "Oswestry Disability Index" will be used to assess the level of disability related to low back pain among participants. This index evaluates the impact of low back pain on daily activities through 10 questions, each scored between 0 and 5, covering aspects such as pain intensity, personal care, lifting, walking, sitting, standing, sleeping, social life, traveling, and changes in pain severity. A lower score indicates a higher quality of life. The validity and reliability of the Turkish version of the index have been established, with a reported Cronbach's alpha of 0.91.
Fatigue Severity Scale	Baseline, at 8 week, at 12 week	The "Fatigue Severity Scale," commonly used in clinical and experimental studies, will be employed to determine participants' fatigue levels. The scale consists of nine questions, each scored from 1 to 7 (1: strongly disagree, 7: strongly agree). The total score is obtained by summing the scores of all items and calculating the average. Higher scores indicate greater fatigue. This scale was developed and adapted into Turkish.
Hospital Anxiety and Depression Scale	Baseline, at 8 week, at 12 week	The "Hospital Anxiety and Depression Scale" will be used to evaluate participants' levels of anxiety and depression. This scale is utilized to determine the risk, severity, and level of anxiety and depression in individuals. The HADS consists of a total of 14 self-report items, divided into two subscales: seven related to anxiety and seven related to depression. Items are rated on a four-point Likert scale ranging from 0 to 3. Higher scores indicate more severe symptoms.
Sit-up Test	Baseline, at 8 week, at 12 week	The "Sit-up Test" will be used to assess trunk endurance among participants. This test measures the strength and endurance of abdominal muscles. Participants will begin in a supine position with knees flexed at approximately 140 degrees, feet flat on the floor, legs slightly abducted, arms parallel to the trunk with palms facing downward. They will be instructed to perform sit-up movements by extending their arms forward and then returning to the starting position. The number of sit-ups completed within one minute will be recorded. Time will be tracked using a stopwatch. The validity and reliability of remote application of this test have been established.
Modified Push-up Test	Baseline, at 8 week, at 12 week	The "Modified Push-up Test" will be conducted to assess trunk endurance. Participants will assume a prone position with hands positioned at shoulder level, elbows flexed, and the body aligned to allow for elbow extension and flexion. They will be asked to lift their head, shoulders, and trunk off the ground by fully extending their elbows and to repeat this movement for 40 seconds. The number of completed push-ups within this duration will be recorded. The validity and reliability of remote application of this test have been confirme.
Plank Test	Baseline, at 8 week, at 12 week	The "Plank Test" will be used to evaluate trunk endurance. Participants will be positioned in a prone posture, resting on their forearms and toes, with their pelvis elevated and their body forming a straight line parallel to the ground. They will be instructed to maintain this position for as long as possible. The duration (in seconds) until the participant can no longer hold the position will be recorded. The validity and reliability of remote application of this test have been verified.
Side Bridge Test	Baseline, at 8 week, at 12 week	The "Side Bridge Test" will be used to assess trunk endurance. Participants will be instructed to lie on their side with their legs extended and the upper arm placed across the chest, touching the opposite shoulder. The supporting elbow will be flexed, allowing weight to be distributed through the elbow and forearm. Participants will be asked to lift their hips off the ground while maintaining a straight body alignment, supported by the elbow and feet. The test will end when the participant loses the correct posture, and the duration (in seconds) of holding the position will be recorded. This test will be performed bilaterally. The validity and reliability of remote application of this test have been confirmed.
Timed Up and Go Test	Baseline, at 8 week, at 12 week	The "Timed Up and Go Test" will be used to assess participants' functional capacity. Participants will be asked to stand up from a chair with armrests, walk three meters, turn around, return to the chair, and sit down. The total time taken to complete this task will be measured. The validity and reliability of remote application of this test have been established.
30-Second Chair Stand Test	Baseline, at 8 week, at 12 week	The "30-Second Chair Stand Test" will be used to assess participants' functional capacity. Participants will use a chair with a seat height of 45-47 cm, ensuring their feet are in contact with the ground. Beginning in a seated position with arms crossed over the chest, they will be asked to stand up and sit down as many times as possible within 30 seconds. The number of completed repetitions will constitute the test score. The participant must fully extend their hips and knees while standing. The validity and reliability of remote application of this test have been confirmed.
