- Registration Number
- NCT03620864
- Lead Sponsor
- Universidad Rey Juan Carlos
- Brief Summary
Low back pain (LBP) is a common condition and has a significant impact on the individual in terms of pain and disability. Lumbar radiculopathy occurs often with LBP and may be the result of a lumbar herniated disc which will irritate a lumbar nerve trunk resulting in intraneural inflammation. There is evidence supporting the use of manual therapies of lumbar radiculopathy. One potential manual therapy is neurodynamic mobilization technique. No scientific evidence, based on a RCT, exists that this particular approach is beneficial for individuals with LBP and lumbar radiculopathy

Group Intervention Description Motor control exercise Motor Control Exercises Patients will receive 8 sessions of motor control exercise program of 30 min duration for 4 weeks, twice per week. Exercises will be demonstrated to the participants by an experienced physical therapist. On each session, the therapist will correct each subject personally. Participants will be asked for practicing the exercises at home once daily for 20 minutes over the 8-week intervention period. The motor control exercise program will consist of a progression from isolated contraction of the transversus abdominis and/or isolated contraction of the multifidi to combined contraction of both transversus abdominis in different positions from supine or prone to bridging or four-point kneeling. Motor control exercise plus neurodynamic intervention Motor Control Exercise Plus Neurodynamic Intervention Patients will receive 8 sessions of motor control exercise program of 30 min duration for 4 weeks, twice per week. Exercises will be demonstrated to the participants by an experienced physical therapist. On each session, the therapist will correct each subject personally. Participants will be asked for practicing the exercises at home once daily for 20 minutes over the 8-week intervention period. The motor control exercise program will consist of a progression from isolated contraction of the transversus abdominis and/or isolated contraction of the multifidi to combined contraction of both transversus abdominis in different positions from supine or prone to bridging or four-point kneeling. In addition, participants allocated to the neurodynamic group will also receive a nerve neurodynamic slider intervention targeting the main trunk of the sciatic nerve of the affected side during al treatment sessions (n=8).
- Primary Outcome Measures
Name Time Method Changes in Lower Extremity Pain Intensity Baseline, after 4 treatment sessions, after 8 treatment sessions,and 2 months after last treatment session A Numerical Pain Rate Scale (NPRS, 0-10) where 0 represents no pain and 10 the maximum pain will be used to record the mean intensity of pain in the lower extremity
- Secondary Outcome Measures
Name Time Method Changes in Related-Disability Baseline, after 4 treatment sessions, after 8 treatment sessions,and 2 months after last treatment session The Roland-Morris Disability Questionnaire will be used for assessing related-disability. The score can range from 0-24 with higher scores indicative of higher related-disability.
Changes in Mechanical Sensitivity of the Sciatic Nerve Baseline, after 4 treatment sessions, after 8 treatment sessions,and 2 months after last treatment session The degrees of the straight leg raise test will be used to assess sensitivity of the sciatic nerve
Changes in Neuropathic Mechanism Consideration Baseline, after 4 treatment sessions, after 8 treatment sessions,and 2 months after last treatment session The Self-report Leeds Assessment of Neuropathic Symptoms and Signs Scale (S-LANSS) will be used for assessing neuropathic mechanism. The S-LANSS is a 7-item tool for identifying patients whose pain is dominated by neuropathic mechanisms. Each item is a binary response (yes or no) to the presence of symptoms (5 items) or clinical signs (2 items). The total score is 24 points and a value ≥ 12 points is indicative of a neuropathic component of pain.
Changes in Pressure Pain Thresholds Baseline, after 4 treatment sessions, after 8 treatment sessions,and 2 months after last treatment session Pressure pain thresholds will be assessed with a mechanical algometer over the common peroneal and tibial nerve
