The aim of the study is to determine if a wearable device that measure physical activity and a smartphone application with nudges and feedback increase the physical activity level of patients with low back pain over a 14 days period.
Secondary to determine how many of the patients, that use the smartphone application, and if they perceived the feedback as inspiring.
And to explore, if a potential effect of the device and smartphone application depended on the baseline activity level, gender, diagnoses, age, education level and previous exercise experience.
1. Is there a difference in average (mean) daily number of active minutes (defined as walking, cycling, running or exercise) over the 14 days intervention period compared to the 14 days control period.
2. If there is an effect of the device and smartphone application, then determine how many of the patients, that use the smartphone application, and if they perceived the feedback as inspiring.
To explore, if a potential effect of the device and smartphone application depended on the baseline activity level, gender, diagnoses, age, education level and previous exercise experience.
3. Is the outcome measures; function measured by sensor, the subjective measurements as pain, stiffness and function, responsive to the intervention compared, to the global scale. 4. Is the patient´s self-evaluated change in activity in the intervention period compared to the baseline period and the control period corelated to the changes in activity measured by the sensor.
The investigators will make a Cross-over, randomized, open label, controlled trial.
Patients will be included from the outpatient clinic, The Department of Rheumatology, Rigshospitalet - Glostrup, Region Hovedstaden, Denmark Inclusions criteria
* Aged 18 years or older
* Non-specific low back pain, spinal stenosis or radiculopathy.
* Not referred for surgical evaluation.
* Patients who scored ≥ 20 point at the Oswestry Disability Index Exclusion criteria
* Patients with comorbidity that prevent them for participating in the study.
* Patients who are judge by the principal investigator to not speak Danish sufficiently to enable them to comprehend the study information and app feedback.
* Patients who already monitor their activity by a watch, on a daily basis.
* Patients with allergy for band aid
* Patients who are pregnant or breastfeeding
The patients are randomized to start with intervention + standard-of-care or only standard-of-care. After completion of the first period the patients will cross-over to the other period.
The patients are randomized by closed envelope. Using a randomization list from randomization.com.
Intervention period
The patients wear the SENS motion patch for 14 days and received daily updates on activity, and suggestions for improvements. During the intervention period the patients receive standard-of-care.
Control period
The patients wear the SENS motion patch for 14 days, but do not receive any feedback from the sensor. During the control period the patients receive standard-of-care.
Standard-of-care
At the outpatient clinic patients are examined by a doctor, receive a diagnosis and may undergo MRI to identify other causes for back pain. They are not offered any training program at the hospital, but they are recommended to stay active and exercise. Some may have a consultation with a physiotherapist one to two times who repeat the advice. Patients are informed that despite pain, they cannot harm their spine by work, exercise or performing daily activities, and that medical staff do not discourage any activities.
