Virtual-reality for Upper Limb Rehabilitation in People With Parkinson's Disease
Clinical and Brain Functional MRI Effects of a Rehabilitative Training of Upper Limb Using Immersive Virtual Reality in People With Parkinson's Disease
The aim of this study is to assess the effect of 8-week physiotherapy training using immersive virtual reality (VR-training) compared to a physiotherapy training performed in a real setting (RS-training) on handwriting and touch screen technology-based activities, brain functional activity and cognition in patients with Parkinson's disease (PD). Both groups will perform upper limb exercises focused at improving movement amplitude and speed during several activities such as writing and using touch screen-technology. Participants randomized to VR-training (N=20) will perform exercises under the augmented visual feedback induced by the VR aimed at stimulating movement amplitude and speed. Participants randomized to RS-training (N=20) will perform exercises in a real setting.
Before training, after training (8 weeks) and at 3-month follow-up (20 weeks), subjects with PD will undergo clinical evaluations (neurological, physiotherapy and neuropsychological) while taking their regular anti-parkinsonian drugs (on-medication state). MRI scans will be acquired at each time-point to assess brain activity reorganization during off state (MRI scans will be acquired at least 12 hours after the regular evening dopaminergic therapy administration to mitigate the pharmacological effects on neural activity). A sample of matched healthy subjects (N=15) will undergo clinical, physiotherapy, neuropsychological and MRI assessments only at study entry as a benchmark.

実験的:VR-training
Upper limb/handwriting exercises in an immersive virtual reality setting
|
Progressively difficult multimodal physiotherapy under the augmented visual feedback induced by the VR. Participants will wear a head-mounted display and their upper limb movements during the training will be captured by a motion tracker. Patients will perform: repetition of movements of upper limb single joints (shoulder, elbow and wrist) under the augmented visual feedback provided by the use of VR in increasingly wide range of movement; active upper limb multi-joints movements under the augmented visual feedback provided by the use of VR (following trajectories designed in the virtual space - movement involving shoulder, elbow and wrist joints) and handwriting tasks and touch screen technology usage in VR context on a tablet and a smartphone. 30 minutes of exercises, 2 times a week, for 8 weeks. |
アクティブコンパレータ:RS-training
The same upper limb/handwriting exercises in a real setting
|
Participants will perform progressively difficult multimodal physiotherapy in a real setting. Participants will be encouraged to perform their upper limb movements during the training in order to perform faster and ampler movements. They will perform: repetition of movements of upper limb single joints (shoulder, elbow and wrist) in increasingly wide range of movement under the feedback provided by therapist; active upper limb multi-joints movements under the feedback provided by the therapist (following trajectories designed on a table or on a blackboard - movements involving shoulder, elbow and wrist joints) and handwriting tasks and touch screen technology usage under the supervision of the therapist. 30 minutes of exercises, 2 times a week, for 8 weeks. |

Systematic Screening of Handwriting Difficulties test (SOS)
時間枠:Baseline, after 8 weeks of training and after 3-month follow-up
|
Systematic Screening of Handwriting Difficulties test assesses handwriting quality on a paper sheet.
Patients copy 5 sentences.
Handwriting quality is evaluated using five items: (i) fluency in letter formation; (ii) connections between letters; (iii) regularity of letter size; (iv) space between words; and (v) straightness of the sentence.
Each item is evaluated with a score ranging from zero to two.
A score of zero is given when the handwriting problem does not occur or is only present in one sentence.
A score of one is given if the problem appears in two or three sentences and a score of two when the problem occurs in more than three sentences.
The total SOS-score is the sum of the scores on the five criteria with a range from 0 to 10, with higher scores reflecting worse quality of handwriting.
Assessment during ON medication phase.
