Study 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.

Eligibility Criteria

Inclusion

Inclusion Criteria:

Stroke patients will be considered eligible for participation if they:

  • had a negative Neer impingement test;

  • could sit or stand up independently at least 10 minutes.

Healthy controls will be considered eligible for participation if they:

  • had no self-reported shoulder pain;

  • had a negative Neer impingement test.
