Effects of Shoulder Stabilization Exercises in the Office Workers With Shoulder Protraction
Condition: Work-Related Condition
Study type: Interventional

Summary: 
      Office workers continuously work with the forward head posture. Forward head posture may
      cause upper extremity problems in the office workers due to the increase in the load on the
      muscles and joints of the cervical spine. This working posture may cause scapular rotation
      downward, increase in activation of the scapular muscles, pain, limited range of motion (ROM)
      and poor proprioception, which can create a vicious circle. Especially in the office workers
      that using computer vibration sensation reduction and upper extremity problems are seen. The
      aim of this study is to investigate the effect of shoulder stabilization exercises on
      scapular dyskinesis, muscle strength, posture and proprioceptive sensory parameters in
      addition to office exercises in the office workers with shoulder protraction.
    

Detailed description: 
      The study is planned so that scapular dyskinesia, muscle strength, posture and proprioceptive
      sense measurements will be taken at 3 different times (before treatment, 8th week and 12th
      week) for two independent groups (control and experimental groups).Based on the
      proprioception sense findings in our previous pilot study, the intergroup effect size was
      predicted to be approximately 0.35 (weak to moderate). Assuming that type I error is 5%, type
      II is 20%, and the correlation between repeated measurements is 80% (high correlation), the
      total sample size obtained with the help of G Power 3.1.9.2 software is calculated as 60
      people. Individuals are randomly divided into two groups (by blocking method). Groups are
      matched by stratified random sampling/proportionate distribution by degree of shoulder
      protraction (acromion level below and above 6.5 cm) and gender.

      Study data will be analyzed using the statistical software [Statistical Package For The
      Social Sciences Software (SPSS 25.0)].Frequency and percentage for continuous data, mean,
      standard deviation, minimum and maximum value for categorical data will be reported.
      Independent sample t-test to determine the difference according to the groups in continuous
      variables, analysis of variance in repeated measures to determine the change over time,
      two-way analysis of variance in repeated measures with repetitions on a single factor to
      evaluate the group and time change together. Pearson chi-square and Fisher-Freeman-Halton
      test will be performed model to evaluate the difference according to groups in categorical
      variables. Bonferonni correction will be used for multiple comparisons, Friedman S and
      Cochran Q tests will be used to evaluate time-dependent variation, and two-way analysis of
      variance will be used for repeated measures with repetitions on a single factor to evaluate
      group and time variation together.The significance level will be accepted as 0.05.
