Achtergrond van het onderzoek
BACKGROUND: Orthopedic footwear is frequently prescribed to a wide variety of patients. Adherence of use of orthopedic footwear is a prerequisite of their effectiveness, but has mostly been assessed using methods, like questionnaires, interviews or diaries, with poor accuracy and reliability. A recent study has shown that temperature can be used to assess orthopedic footwear adherence, however, the sensor used could only collect data over a short period of time and had relatively large dimensions. A new technology is available, comprising a temperature sensor that is small and capable of long-term data collection (>100 days).
AIM: To assess the validity and feasibility of a new temperature sensor for measuring footwear use and nonuse in healthy individuals.
METHOD: In ten healthy volunteers, the validity of a new temperature sensor to discriminate between time periods of use and nonuse of footwear over a period of 48 hours was assessed. Footwear use measured with the sensor was compared to footwear use measured with a 1-minute time-lapse sports camera secured to the shoelace and focused on the lower leg. The correlation coefficient between footwear use based on the sensor and camera was calculated. The ease of the installation of the sensor in the insole and the data collection and analysis were assessed as feasibility criteria.
RESULTS: Mean footwear use measured with the camera was 8.10 (±2.46) hours per day, and measured with the sensor 8.16 (±2.37) hours per day. There was a strong correlation between footwear use assessed by camera and by sensor, r = 0.995.
DISCUSSION & CONCLUSION: The temperature sensor is valid and feasible for adherence monitoring in (orthopedic) footwear. The installation of the sensor, in the insole of the subjects' preferred footwear, and the data collection were performed easily.
