METHODS: A within-subject, repeated-measures, crossover randomized controlled design was conducted among 25 participants (7 males and 18 females) with chronic nonspecific low back pain. All the participants received 3 different types of experimental interventions, which included LPST, the passive automated cycling intervention, and the control intervention randomly, with 48 hours between the sessions. The pressure pain threshold (PPT), hot-cold pain threshold, and pain intensity were estimated before and after the interventions.
RESULTS: Repeated-measures analysis of variance showed that LPST provided therapeutic effects as it improved the PPT beyond the placebo and control interventions (P < 0.01). The pain intensity under the LPST condition was significantly better than that under the passive automated cycling intervention and controlled intervention (P < 0.001). Heat pain threshold under the LPST condition also showed a significant trend of improvement beyond the control (P < 0.05), but no significant effects on cold pain threshold were evident.
CONCLUSIONS: Lumbopelvic stabilization training may provide therapeutic effects by inducing pain modulation through an improvement in the pain threshold and reduction in pain intensity. LPST may be considered as part of the management programs for treatment of chronic low back pain.
OBJECTIVE: To evaluate the effectiveness of CBB on respiratory variables among NS-LBP patients.
STUDY DESIGN: pre- and post-experimental study.
PARTICIPANTS: Forty participants were assigned to an experimental group (EG) [n = 20] and control group (CG) [n = 20] based on the study criteria.
INTERVENTIONS: The EG received CBB together with routine physiotherapy and the CG received routine physiotherapy over a period of 8 weeks. Participants were instructed to carry out the exercises for 3 days per week. The training was evaluated once a week and the exercises progressed based on the level of pain.
OUTCOME MEASURES: Primary outcomes were maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP) and maximum voluntary ventilation (MVV). The secondary outcomes were measured in the numeric rating scale (NRS), total faulty breathing scale (TFBS), cloth tape measure (CTM) and lumbo-pelvic stability.
RESULTS: The MIP increased significantly among the EG when compared with that in the CG (p > 0.05).The EG showed a significant increase in MVV (p = 0.04) when compared to the CG (p = 0.0001). There was a significant reduction in pain for both groups. The MEP, TFBS, chest expansion and core stability showed no changes in either group.
CONCLUSION: CBB was effective in improving respiratory variables among NS-LBP patients.
