The LMC12 is a new optoelectronic system for capturing the motion of both hands within a virtual reality environment and has become commercially available during the past years. This inexpensive, marker less motion sensing system tracks forearm, wrist, and hand position.13 It consists of three Infrared Light emitters and two Charge-Coupled Device cameras placed inside a small casing.14 With a within accuracy of < 0.2 mm,14 the LMC is able to reliably detect static objects. Furthermore, it is small (80 mm x 30 mm x 11.25 mm),12 portable, user-friendly, and could easily be connected to a computer or laptop. LMC may be a feasible rehabilitation tool to perform manual dexterity exercises, either in a rehabilitation setting or at home.
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
