Daily physical activities in chronic lower back pain patients assessed with accelerometry

Results Data were obtained from 29 CLBP patients and 20 controls. Results show that the overall activity levels of patients (mean 0.75; SD 0.43) are not significantly different from those of controls (mean 0.71; SD 0.44). However, patients show significantly higher activity levels in the morning (p < 0.001) and significantly lower activity levels in the evening (p < 0.01) compared to controls. No significant differences in activity levels were found between leisure time and working days within either group; furthermore no significant differences in activity levels were found between patients with different work status. Conclusion Overall activity levels do not differ significantly between CLBP patients and controls, but the distribution of activities over the day differs significantly.
