The participants will receive 20 minutes of robot assisted tenodesis-grip therapy, followed by 20 minutes of regular motor task specific training in each treatment session.

The participants will receive 20 minutes of traditional occupational therapy (sensorimotor facilitation techniques, such as: Rood, Bobath and propriocetive-neuromuscular-facilitation), followed by 20 minutes of motor task specific training in each treatment session.

motor task specific training

Each item is rated on a three-point ordinal scale (2 points for the detail being performed completely, 1 point for the detail being performed partially, and 0 for the detail not being performed). The maximum motor performance score is 66 points for the upper extremity.completely, 1 point for the detail being performed partially, and 0 for the detail not being performed). The maximum motor performance score is 66 points for the upper extremity.

Muscle tone is defined by the resistance of a muscle being stretched without resistance.

The score is the number of blocks carried from one box to the other in one minute. Higher values represent a better outcome.

The Semmes-Weinstein monofilamenttest examines the cutaneous pressure threshold, range from 1.65-6.65. Higher values represent a worse outcome.

MAL is a structured interview with testing sensitivity used to examine how much (amount of use, AOU) and how well (quality of movement, QOM) the subject uses their more-affected arm. For the 30 items MAL, each item is scored on a 0-5-ordinal scale.

Self-reported improvement over the treatment period,. The scale, rated from 1 (very much improved) to 7 (very much worse), is as the indicator for determining perceptible change of the patients for assisted tenodeis-grip robot system.
