Brief Summary

This study aims to verify if patients with nerve-related leg pain benefits from neurodynamic treatment over two weeks.

Detailed Description

Nerve-related leg pain (NRLP) although less prevalent than low back pain itself, is associated with higher economic and social burden, and has been considered a predictor of chronicity and disability among subjects with low back pain.

Numerous approaches are proposed for its management; however, evidence regarding the best therapeutic approach is lacking. Neurodynamic techniques are proposed to be effective to manage NRLP.

Thus, this study aims to verify, through a randomized controlled trial, the effectiveness of a two-week program of neurodynamic techniques on pain and disability in individuals with NRLP.

Conditions

Nerve Pain; Peripheral Nerve Injuries; Peripheral Nervous System Diseases; Sciatica; Low Back Pain; Low Back Ache; Signs and Symptoms

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: SINGLE

Study Groups

Neurodynamic group

Patients allocated to this group will receive three different neurodynamic techniques: a lumbar foramen dynamic opener; a side-lying slider and a slider in the slump position. Patients will be asked to perform home exercises (a slider and a tensioner technique). Treatment will receive four treatments during two weeks (two sessions/week).

Group Type: EXPERIMENTAL

Neurodynamic Group

Intervention Type: PROCEDURE

All techniques will be executed in a pain-free way (grade III). Mild discomfort will be accepted, but it must subside as soon as the technique ends.

• In the dynamic opener technique, patient will be positioned in side-lying, with the affected side upwards. The therapist will then perform grade III oscillations aiming to open the lumbar foramen;
• In the side-lying slider, the patient will be in side-lying with the affected side upwards. A combination of knee and hip flexion and extension movements will produce sliding in the neural structures;
• In the slump slider, the patient will be seated in slump position. Combinations between neck and knee movements will produce greater nerve excursion than the side-lying slider. Patients will perform the slump slider in a pain-free manner.

Control Group

Patients allocated to Control Group (CG) will receive no intervention and will be advised according to the best evidence available; i.e, advice to remain active and to resume activities of daily living

Upon trial completion, treatment will be offered.

Group Type: NO_INTERVENTION

No interventions assigned to this group
