Effectiveness of mid thoracic spine mobilization on postural balance and gait ability in subacute stroke patients: A randomized clinical trial

Abstract

BACKGROUND: Although mulligan sustained natural apophyseal glides (SNAG) and maitland mobilization (MM) are common interventions for musculoskeletal disease, no study has directly compared the effectiveness of mid-thoracic spine mobilization in subacute stroke patients. OBJECTIVE: To investigate the effects of mid-thoracic spine mobilization (SNAG vs. MM) on postural balance and gait ability in subacute stroke patients. METHODS: Fifty subacute stroke patients were randomly allocated to the SNAG (n= 17), MM (n= 16), and control (n= 17) groups, each receiving a neuro-developmental therapy program for four successive weeks. The SNAG and MM groups additionally received mid-thoracic spine mobilization (T4∼8). The primary outcome measure was postural sway, and secondary outcome measures included the five times sit-to-stand test (FTSST), functional reach test (FRT), 10-m walk test (10MWT), 6-minute walk test (6MWT) and global rating of change (GRC). RESULTS: Participants reported no adverse events, and there was no loss to follow-up. The SNAG and MM group patients demonstrated significant improvements (p< 0.05) in postural sway, FTSST, FRT, 10MWT, and 6MWT compared with those in the control group, with no between-group differences. CONCLUSIONS: Mid-thoracic spine mobilization allows significant improvements in postural balance and gait ability in subacute stroke patients, with no differences between the SNAG and MM techniques.
