Participants with chronic stroke underwent 24 sessions of vibration stimulation combined with task-oriented training over 12 weeks, in addition to regular therapy.

Fugl-Meyer assessment - wrist and hand is used to assess wrist and hand motor impairments in people with post stroke hemiplegia. Scoring is conducted through the direct assessment of the individual's performance, whereby the 12 items on the scale are scored according to their level of completion using a 3-point ordinal scale: 0 indicating inability to perform, 1 indicating partial performance, and 2 indicating full performance. The minimum score is 0. The total score is 24. The higher the score, the better the hand and wrist motor function.

Box and Blocks Test is a test of manual dexterity to assess hand function. The minimum score is 0. The total score is based on the number of blocks transferred from one box to the other in 60 seconds. Higher score is indicative of better hand dexterity.

The Motor Activity Log is a structured interview intended to measure an individual's real life functional affected upper limb performance. The Motor Activity Log consists of two subtests: one pertaining to the amount of use (AOU) and the other pertaining to the quality of movement (QOM) of the affected upper limb. The Motor Activity Log employs an 11-point Likert scale, ranging from 0 to 5 with half-point increments, to evaluate the AOU and QOM subtests. The scores for AOU vary from 0, indicating never use the affected limb for this activity, to 5, indicating always use. Similarly, the scores for QOM range from 0, representing an inability to use the affected limb during the activity, to 5, indicating an ability to use the affected limb just as proficiently as before the stroke. Higher scores represent better performance.
