The aim of this cross-sectional observational study was to investigate adherence rate and
factors influencing the adherence in following home-based activity advice, in patients referred to a
physiotherapy clinic for non-specific low back pain. Research suggests that inadequate adherence to
home-based activity advice during an intervention period may diminish treatment outcomes. Factors
negatively influencing adherence appeared to be related to a person's beliefs and perceptions.
Perceived barriers, low self-efficacy and unbeneficial illness beliefs have been consistent predictors
for non-adherence across studies. 51 patients who reported non-specific low back pain were advised
to walk daily. Physical activity was measured with a validated triaxial seismic accelerometer. The
effect of multiple patient-related determinants on the rate of adherence was studied. Only four out of
51 patients (8%) fully adhered to the walking advice. In this study, there were no significant effects of
patient-related determinants on the rate of adherence. Factors negatively influencing adherence
behaviour were lack of time, weather conditions and increasing low back pain. In conclusion, patient
adherence in following home-based activity advice for non-specific low back pain outside the clinical
setting is poor.
