Clinical Trial Summary

The goal of this observational study is to compare the activity levels of the periscapular (levator scapula, serratus anterior, infraspinatus, upper, middle and lower trapezius) muscles during open and closed kinetic chain activities in individuals with stroke. It is also aimed to reveal the relationship between the timing and percentage of scapular muscle activation, the viscoelastic properties of these muscles, motor performance and capacity. The main questions it aims to answer are: - The activation timing, percentage and viscoelastic properties of the periscapular muscles of stroke individuals compared to healthy individuals; - The activation timing and percentages of periscapular muscles during closed kinetic chain and open kinetic chain activities in stroke individuals; - The relationship between muscle activation timing, muscle activation percentage, viscoelastic properties, upper extremity motor performance and capacity. The study will include both hemiplegic (n=10) and healthy (n=10) participants. All of the participants will be assessed in terms of scapular muscle activation timing and percentage (with superficial electromyography) during both open kinetic chain and closed kinetic chain activities. viscoelastic properties of muscles (Miyoton) will be evaluated. Upper extremity movement frequency and quality (MAG-28) and functional performance (Fugl-Meyer) will be evaluated to reveal the status of stroke individuals. In the study, it is also aimed to reveal the relationship between the timing and percentage of scapular muscle activation, the viscoelastic properties of these muscles, motor performance and capacity. 10 healthy and 10 hemiplegic individuals are planned to participate in the study.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Muscle activation timing and percentage	Noraxon Surface Electromyography System will be used to assess muscle activation timing and percentage of upper, middle and lower trapezius, serratus anterior, infraspinatus, levator scapulae of all participants. The placement of electrodes will be done according to SENIAM's European Recommendations for Surface Electromyography. Synchronized video capture will be used to determine the phases of the scapular motion during the open and closed kinetic chain exercises (OKC and CKC, respectively). To take the measurement during OKC, participants will be seated in a chair that will support the waist and back, with the feet in contact with the ground. They will be asked to cross the fingers of both hands and to raise both arms overhead as high as they can. For CKC, they will be asked to stand next to a table at level of SIAS and place their forearms on table with the elbows flexed. They will be asked to extend the elbow of the non-measuring arm while shifting body weight to the other side.	1 day
Primary	Viscoelastic properties	Myoton®PRO Digital Palpation Device will be used to measure the muscle tone, stiffness, and elasticity of muscles below. The patient will be seated with the flexed elbow supported by a pillow next to the body. Measurements will be repeated 3 times.; Upper Trapezius: the end-points of a line connecting the spinous process of C7 and the acromion, distally, from the mid-point of the muscle belly; Middle Trapezius: the mid-point of a line connecting T4 spinous process to the medial border of spina scapula; Lower Trapezius: The mid-point of a line connecting the spinous process of T6 to the medial border of spina scapula; Serratus anterior: a- Over the fourth rib, at the midpoint between the latissimus dorsi and the pectoralis major; b- Over the seventh rib, in the midline of the axilla; Infraspinatus: Two fingers breadth below the center spine of the scapula; Levator Scapulae: Between the posterior margin of SCM and anterior margin of the UT, at level of C4/5	1 day
Secondary	Upper extremity motor performance	The Fugl-Meyer Assessment (FMA) is a stroke-specific, performance-based impairment index. It is designed to assess motor functioning, balance, sensation and joint functioning in patients with post-stroke hemiplegia. It will be used for the participants only with hemiplegia.	1 day
