The Modified Hand Injury Severity Score is used to determine the severity level of patients' injuries. At the 6th and 12th weeks following the injury or surgery, patients are administered the Manual Ability Measure-36 questionnaire, and the Jebsen-Taylor Hand Function Test and Nine-Hole Peg Test are performed. Additionally, the grip strength of the subjects is evaluated at the 12th week.

It is a four-component scoring system developed to determine the severity of hand and forearm injuries: integumentary (skin and nail), skeletal (bone and ligament), motor (tendon), and neurovascular (nerve and vascular). The total score is obtained by summing the scores of all components and is classified into four categories: minor (<20), moderate (21-50), severe (51-100), and major (>101) injury.

It is a self-report questionnaire specifically developed to measure hand dexterity. It is an outcome measure that reflects patients' perceived functional hand use or their ability to perform activities of daily living. Higher scores indicate higher levels of function.

It consists of seven subtests: writing, turning over cards, picking up small common objects, simulated feeding, stacking checkers, moving light objects, and moving heavy objects.

It is a simple, rapid, and manual dexterity test with proven validity and reliability. It is particularly sensitive to changes in upper extremity performance.

These measurements are performed according to the procedure recommended by the American Society of Hand Therapists.
