A measure to evaluate users’ usability (i.e. feasibility) is the System Usability Scale (SUS). This questionnaire, developed by Brooke (1996),15 is a ten-item Likert scale which takes three usability criteria into account: effectiveness, efficiency, and satisfaction.16 A score of 60 percent up to a maximum 100 percent represents a feasible tool, where higher scores indicate better usability.15,17 …show more content…
Therefore, the aim of the present pilot study was to evaluate the feasibility measured by the SUS of the LMC in PD patients with impaired manual dexterity in different stages of the disease. Furthermore, we looked at the preliminary efficacy of the LMC on improving manual dexterity. In addition, we examined differences in HRQoL between baseline and post-intervention. We hypothesize that the LMC is a feasible (i.e. SUS score ≥ 60 percent) rehabilitation tool in PD patients with impaired manual dexterity in different stages of the
