Objectives: To test the effect of adding neural mobilization (NM) versus myofascial release (MFR) to stabilization exercises (SE) on disability, pain, and lumbar range of motion (ROM) in patients with lumbar spine fusion (LSF).

Design: A single blinded, parallel groups, randomized controlled trial.

Setting: Outpatient public and governmental hospital clinics.

Participants: Patients (N=60) who had undergone LSF were randomly assigned into 3 equal groups.

Intervention: Group I received NM plus SE, group II received MFR and SE, and group III received SE only. Each group visited the hospital 3 times a week for 4 weeks.

Main outcome measures: Oswestry disability index (ODI), visual analog scale, and back range of motion (BROM) were assessed before starting treatment, immediately after finishing treatment, and 1 month later.

Results: There were statistically significant differences among the groups regarding the ODI and pain (P<.05) in favor of the study groups, but no statistically significant differences were found among groups regarding the BROM outcome (P>.05). Regarding the within-group effect, statistically significant differences were found in all outcomes after 1 month of treatment, as well as after 1 month of follow-up in each group (P<.05).

Conclusions: Patients who received NM or MFR combined with SE demonstrated better improvement, in favor of the NM group, regarding disability and pain than patients who received SE alone after LSF. No differences were found among the groups regarding lumbar ROM.
