Abstract
Background and Purpose: Current clinical guidelines recommend supervised exercise as a first-line treatment in the management of low back pain (LBP). To date studies have not used objective forms of measuring changes in free-living physical activity (FLPA). The aim of this study was to compare FLPA between two groups who received either supervised exercise and auricular acupuncture (EAA) or exercise alone (E).
Methods: 51 patients with non-specific LBP [mean±SD=42.8±12.4 years] wore an accelerometer for 7 days at baseline, end of the intervention (week 8) and follow up (week 25). FLPA variables were extracted: % time (hours) spent in postures; daily step count and cadence. Data were analysed using SPSS (v15). Repeated measures ANCOVA were performed using a mixed linear model.
Results: There was no difference in daily step count between the two groups at any time point (E, mean±SD, week 1, 8197±2187; week 8, 8563±2438, week 25, 8149±2800; EAA, mean±SD, week 1, 8103±1942; week 8, 8010±2845, week 25, 8139±1480, p=0.9) or cadence. No differences in postures were noted, apart from time sitting/lying which was shorter at week 25 in the E group (p=0.006).
Conclusions & Implications: Supervised exercise classes, with or without acupuncture, do not produce changes in FLPA in the short term or longer term in people with LBP. This suggests more effective ways should be sought to encourage the patient to incorporate activity into their daily lives. These findings have informed the design of two walking intervention trials for LBP patients.
