Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention program will be administered twice a week, 45 minute sessions, for 5 weeks by a qualified Occupational Therapist with experience with Parkinson's Disease (PD). both groups (intervention and comparator group) will receive intervention in one-on-one sessions once a week face to face in the Clinic or the patient's home and once a week on zoom from the patient’s home.
intervention description: Motor Imagery intervention- practice of dexterity exercises will be performed after imagining the exercise in the first person. After imagining the movement, the patient will perform the activity with the hand that he was instructed to imagine using. For Activities of Daily Living (ADL) which are unilateral practice will be performed only with the dominant arm – following imagery of the activity. For bilateral ADL’s practice will be performed after imagining the activity. Motor imagery will be performed with the verbal guidance of the Occupational Therapist.
After 3 weeks both groups will be asked to give 2-3 dexterity based activities that are meaningful and difficult for them in daily function, those activities will be integrated into the intervention.
Session attendance will be followed and reported.

Rehabilitation
Comparator / control treatment
comparator group: Cross Education intervention - practice of dexterity exercises (e.g. versatile manipulation exercises such as collecting toilet paper etc.) will be performed several times with the unaffected side and only thereafter with the more affected side to facilitate cross education. For ADL’s that are unilateral practice will be performed only with the dominant arm. For ADL’s which are bilateral (e.g. cutting food or buttoning), practice of dexterity exercises mentioned above will precede their practice, after which bilateral ADL’s will be practiced with both hands with dominance and previous patient’s function determining each hand’s function within the activity (e.g. a patient that is accustomed to cutting food with the knife in the right hand and the fork in the left will practice with the same laterality in the intervention).

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation will be concealed- the person who determines if a subject was eligible for inclusion in the trial will be unaware of the allocation- when the decision will be made and to which group the subject will be allocated.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
block randomization with computerised sequence generation and stratification.
Stratification will be according to the UPDRS II score (cut off point 17).

Summary
Brief summary
Parkinson’s Disease (PD) leads to complex pathological characteristics demonstrated in versatile motor and cognitive profiles. The symptoms which develop over the course of the disease changes the person with Parkinson’s ability to carry out everyday activities. Functional decline in PD has a large impact on QOL, is first characterized by difficulties in ADL’s such as house work, dressing and writing and was found to decline in connection with cognition. In regard to motor function dexterity was found to be associated with ADL independence more than tasks related to lower limb function or gross upper limb (UL) function. In order to maximize the benefits of rehabilitation of PWP’s, it is essential to better understand the interaction between cognition and motor learning strategies.
This will be performed by designing and comparing between two intervention programs - Motor Imager (MI) and Cross Education (CE) - focused on improvement in Upper Limb (UL) functional ability (i.e. dressing, eating, etc.). efficacy of intervention will be assessed in regard to the participant’s personal improvement, additionally cognition will be analyzed as a potential mediating factor in the efficacy of the intervention type. Our ultimate goal is to enhance knowledge translation by creating a manual for clinicians whereby a cognitive exam administered at the beginning of an intervention period, will facilitate clinical reasoning in choosing the most efficient motor learning strategy for a specific patient.
Aims:
1. Comparing lasting effects of MI and CE strategies in improving UL motor performance and ADL function in PWP’s.
2. Examine associations between cognitive profile and improvement in UL motor performance and daily function due to implementation of each strategy.
3. Creating a manual for therapists to facilitate clinical reasoning in choosing the most efficient motor learning strategy for a specific patient.
Hypothesis:
1. MI will be less beneficial than CE in improving overall motor functional performance.
2. Better cognitive abilities will be associated with higher improvement in motor performance and ADL in both strategies: executive function will be associated with higher MI benefits, lower cognitive ability will benefit more from CE.
