Objective: With a view to introducing routine care, this qualitative study addresses the questions of the choice of body-worn sensors (BWS) according to the context of the care pathway for patients with Parkinson’s disease (PD).

Background: BWS could be a standard support for adjusting antiparkinsonian therapy. The acceptability and usability of these medical devices by patients and professionals is crucial for optimal use.

Method: Two semi-structured interviews were conducted with 22 Parkinson’s patients, before and after the use of a BWS specialized in PD symptoms monitoring for home use during one week. Patients assessed their perception of the usability and attractiveness of the devices using two standardized questionnaires (System Usability Scale [1], AttrakDiff [2, 3]). A semi-structured interview was conducted with six neurologists and three expert nurses. The qualitative analysis of the 53 interviews was carried out with NVivo software [4].

Results: Patients find the 3 devices attractive (pragmatic and hedonic qualities of AttrakDiff high for all) and convenient. They volunteer for their use and evaluate them with the SUS with scores greater than 85/100, which correlates with “excellent” to “best imaginable” ratings [5].
Health professionals admit that these tools will be essential in practice but express fears (time required for training, establishment and use, substitution of the human relationship for the analysis of results).

Conclusion: Patients rate all 3 devices positively. Healthcare professionals suggest a selection of the sensor based on the medical purpose and patient profile. Feedback reveals a need for support at various stages of the patient’s follow-up with BWS monitoring, from the choice of device, handling by healthcare professionals and patients, to the analysis of the results.
The perception of objective monitoring is promising for professionals but must be framed. Patients have adopted the devices and plan to improve their management.
