Reliability and Validity of the Selective Control of the Upper Extremity Scale in Stroke Patients

Study Overview
=================
Brief Summary
-----------------
Selective motor control is defined as the ability to perform the movement in isolation without revealing movement in another joint, without mirror movements, without using a flexor or extensor pattern in the extremities during a desired movement in one joint. Evaluation of selective motor control is important to predict future functional status in adult stroke patients. The Fugl-Meyer Upper Extremity Motor Rating Scale is the basic test in the assessment of motor functions in stroke patients. However, this test is a complicated scale and it takes more than one hour to complete the rating of the patient; Physicians without experience cannot perform the test because it is difficult. This planned study aims to demonstrate the validity and reliability of Selective Control of the Upper Extremity Scale (SCUES) in the evaluation of selective motor control of upper extremity in stroke patients; thus, it aims to present SCUES to medical professionals as a practical clinical tool to be used in stroke.

Detailed Description
-----------------
According to the definition of the World Health Organization, stroke is a clinical syndrome characterized by rapid localization of the signs and symptoms of focal cerebral function loss for no apparent reason other than vascular causes, and the findings last longer than 24 hours. It is the second leading cause of death in the world. and is one of the most common causes of adult-onset disability. Motor Control is defined as the ability to regulate or direct the mechanisms and systems necessary for the realization of movement. Coordinated contraction and relaxation of muscle groups in humans is accomplished by both reflex mechanisms and higher brain centers that manage functions. Selective motor control is defined as the ability to perform the movement in isolation without revealing movement in another joint, without mirror movements, without using a flexor or extensor pattern in the extremities, during a desired movement in one joint. Selective motor control skill is responsible for agile and independent movement and control of the joints. Evaluation of selective motor control is important to predict future functional status in adult stroke patients. Motor impairment in stroke; Tone, strength, coordination and balance should be evaluated with examinations. Scales such as Fugl-Meyer Upper Extremity Motor Evaluation Scale, Motor Evaluation Scale, Motricity index are frequently used for motor functions. The Fugl-Meyer Upper Extremity Motor Rating Scale is the basic test in the evaluation of motor functions in stroke patients. However, this test is a complicated scale and it takes more than one hour to complete the evaluation of the patient; Physicians without experience cannot perform the test because it is difficult. In conclusion, the Fugl-Meyer Upper Extremity Motor Rating Scale is administered by a small number of clinicians. However, evaluation of selective motor control in stroke is important both for the functional prognosis of the patient and for deciding on treatment interventions. The Upper Extremity Selective Control Scale (SCUES) was developed to evaluate selective motor control in patients with cerebral palsy, a pathology of the central nervous system such as stroke. It is a practical and short-term test with proven validity and reliability in the pediatric population with cerebral palsy. This planned study aims to demonstrate the validity and reliability of SCUES in the evaluation of selective motor control in stroke patients; thus, it aims to present SCUES to medical professionals as a practical clinical tool to be used in stroke.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Selective Control of the Upper Extremity Scale (SCUES) | The SCUES is a video-based assessment tool that evaluates selective movements of shoulder, elbow, forearm, wrist, and fingers bilaterally.The test is performed as follows. The child is seated at a table front of the camera. The examiner demonstrates the desired movements to the child, and then passively moves the joint to represent the desired movement. The child is then asked to perform the desired movement actively. The video camera is placed in front of the participant from frontal plane. Selective voluntary motor control (SVMC) is scored as normal SVMC (3 points), mildly diminished SVMC (2 points), moderately diminished SVMC (1 point), and no SVMC (0 points) for each joint. The degree of SVMC is determined by the presence of 4 characteristics (movement in joints other than target joint, mirror movements, trunk movements, observed movement less than passive range of motion).The score of each joint is summed up to a maximum of 15 points per limb. | 15 min |
