Description

The Wolf Motor Function Test (WMFT-27) is an assessment tool used to evaluate motor function, primarily in individuals who have experienced a stroke or other neurological disorders. It was developed to measure upper-extremity functional ability in patients presenting with sensory and motor difficulties. The test examines several aspects of motor performance, including speed, accuracy, and the ability to complete specific motor tasks.

Aim

The primary aim of the WMFT-27 is to assess the functional ability of the upper extremities and to monitor the progress of patients with neurological disorders. The instrument can provide useful information for planning therapeutic interventions and evaluating the effectiveness of rehabilitation programs.

Analysis and Use of Data

The WMFT-27 includes 27 predefined tasks that assess an individual’s ability to perform different motor activities. These tasks range from relatively simple movements, such as lifting objects, to more complex activities requiring coordination and precise movement. Performance is recorded according to the time required to complete each task and the accuracy of execution.

Two principal aspects are considered during assessment: execution time and movement accuracy. Execution time reflects the speed with which each task is completed, while movement accuracy concerns the individual’s ability to complete the task correctly and without errors.

The resulting data can be used to monitor changes in motor performance over time and to evaluate outcomes associated with rehabilitation interventions.

Scoring

The scoring procedure of the WMFT-27 is based mainly on two indicators: task completion time and accuracy. The time required to complete each task is recorded, while accuracy is assessed according to whether the movement is performed correctly without requiring correction or repetition.

Each task is scored separately, and the individual scores can then be combined to provide an overall picture of the patient’s motor function.
