Relationship Between Upper Extremity' Viscoelastic Properties and Functionality in Subacute Stroke

Study Overview
=================
Brief Summary
-----------------
In stroke patients, the shoulder-upper extremity complex is affected and reduces independence and quality in activities of daily living. Investigating the relationship between the functions of the upper extremity muscles and viscoelastic properties is important in understanding the rehabilitation of individuals with stroke.

Detailed Description
-----------------
Upper extremity functions of individuals will be measured and correlated with viscoelastic properties of upper extremity muscles. The box and block test will be used for the function test. The viscoelastic properties of the muscles will be measured with the myotonPRO device. Deltoideus, Triceps, Biceps, Brachioradialis and Extansor digitorum longus were evaluated with myotonPRO. The tonus, stiffness and elasticity of muscles were recorded. Assessments will applied bilaterally and average recorded.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Stiffness | stiffness (N/m) is a biomechanical feature of the muscle that characterizes its resistance to a contraction or an external force. | through study completion, an average of one month | 
| Elasticity | The elasticity is measured as a logarithmic decrement (log) of the natural oscillations in the tissue. Logarithmic decrement describes the tissue's ability to restore its shape after being deformed | through study completion, an average of one month | 
| Tone | Oscillation frequency (Hz) refers to the tone of a muscle while resting, | through study completion, an average of one month | 
| Functionality- Box and Block Test | Te Box and Block Test (BBT) is one of the most used and recommended tools to evaluate unilateral manual dexterity. The BBT comprises a box divided into two compartments by a wooden separation and 150 small wood cubic blocks (1-inch). The BBT consists of displacing a maximum number of small blocks, one-by-one, from the compartment located on the tested side to the other using the same hand (taking care to pass over the separation). Te score is obtained by counting the number of blocks correctly displaced within 60 s. | through study completion, an average of one month |
