Objective: To analyze the opinion of different neurologists from Spain about the STAT-ON tool after using the device in a real clinical practice setting (RCPS).

Background: The identification of motor fluctuations in Parkinson´s disease (PD) patients is important for PD treatment but not straightforward. STAT-ON is an objective tool that registers ON-OFF fluctuations making possible to know the state of the patient for a week (1,2).

Methods: CE Mark Medical Device STAT-ON was provided by the Company Sense4Care to Spanish neurologists for using it in a RCPS. All neurologists were expert on PD. Each neurologist had the device for at least 3 months and could use it in PD patients at his/her own discretion. In February 2020, a survey with 30 questions was sent to all participants. The data was anonymized and 3 waves were made to obtain the responses.

Results: A total of 27 surveys were received (51.9% females; mean age 44.9 ± 9 years old). Two thirds of the neurologists worked in a Movement Disorders Unit, the mean experience on PD was of 16 ± 6.9 years, and 59.3% of them had used previous different devices for PD. A total of 119 evaluations in 114 patients (range from 2 to 9 per neurologist; mean 4.5 ± 2.3) were performed. Using a score from 1 (unhelpful) to 7 (very helpful), the opinion about different usability aspects was recorded (Table 1). The subjective general opinion about the device (from 0, the worst, to 10, the best) was 6.9 ± 1.7. STAT-ON was considered better than the diaries by 70.3% of the neurologists (Figure 1A) and a useful tool for identification of advanced PD patients by 81.5%. A high percentage of PD patients were considered that could benefit from using STAT-ON (Figure 1B). STAT-ON was considered from quite to very useful by 74% of the neurologists (Figure 1C). A correlation was observed between the number of assessments performed and the opinion about the device (r=0.403; p=0.046). Proper identification of FOG episodes and falls were the most frequent limitations reported.

Conclusions: STAT-ON could be a useful device for using in PD patients in clinical practice.

This is a paragraph.It is justify aligned. It gets really mad when people associate it with Justin Timberlake. Typically, justified is pretty straight laced. It likes everything to be in its place and not all cattywampus like the rest of the aligns. I am not saying that makes it better than the rest of the aligns, but it does tend to put off more of an elitist attitude.
