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).

Secondary outcome [1] 416313 0
The dexterity questionnaire (DextQ-36 - revised) : The DextQ-36 - revised is a patient-reported dexterity questionnaire regarding ADL functions that require complex UL function. It is based on the dextQ-24 and approval was attained from the main author to perform an official translation process as well as changes to items.

Prior to intervention initiation, at intervention end and at a 4 week follow up.
Secondary outcome [3] 416315 0
The Coin Rotation Task is a test measuring hand dexterity. The task requires the participant to rotate a U.S. nickel (in Israel will be performed with a 10 agorot coin) through consecutive 1800 turns using the thumb, index and middle fingers, as rapidly as possible for 20 rotations.

The TATOO is a touchscreen assessment tool that measures hand dexterity abilities (developed by Danial-Saad& Chiari, 2017). It tests intentional movements aimed at touchscreen use such as tapping, swiping, pinching and other motor activities of the hand.

Study design
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).
