Participants
Sixty men and women with chronic nonspecific LBP of at least 3 months in duration volunteered to participate in this study from a total of 112 people who were screened for participation (fig 1). This study was approved by our local ethics committee, and all subjects provided informed written consent before participation. Exclusion criteria included the presence of severe postural abnormality or neuromuscular disorder; previous diagnosis of pathology (confirmed by magnetic resonance imaging or
Results
The results from table 1 present the demographic information from the subjects separated by group.
Summary of the Main Results
The results of this study do not support the hypothesis that spinal manipulation and exercise would lead to a greater change in the neuromuscular measures used in this study compared with the alternative treatment groups. However, the study results did provide support for the efficacy of supervised exercise in yielding a more rapid improvement in functional disability and the FR response.
Changes in FR Response
There is some research that has found improvements in the FR response after exercise, specifically manifest
Conclusions
Supervised exercise was a more rapid means of eliciting neuromuscular improvement, manifest by an increased FR response. The unsupervised exercise program also showed chronic neuromuscular improvement. No treatment effects were identified for either neuromuscular improvements or disability, although there is a possibility of type II error because sample-size calculations were based on changes in disability. This study has provided data that can be used for future sample size calculations in
