About this study

Official title: The Relationship Between Thoracic Kyphosis Angle and Shoulder Pain, Range of Motion, Isokinetic Muscle Strength, and Functionality

This study aimed to investigate the correlation between increased thoracic kyphosis and these factors.

Read the detailed description

Thoracic kyphosis angle was assessed with a manual inclinometer, shoulder pain severity with a Visual Analog Scale, shoulder range of motion with a manual goniometer, shoulder isokinetic strength with an isokinetic dynamometer, and upper extremity function with the Quick Disability of the Arm, Shoulder, and Hand questionnaire.

Conditions: Shoulder Pain, Thoracic Kyphosis
Being tested: Thoracic Kyphosis isokinetic measurement
Medical subject headings: Shoulder Pain

What is being measured

The primary outcome is the main question the study is designed to answer.

Assessment of the angle of thoracic kyphosis
Participants' thoracic kyphosis angle was assessed using two gravity-dependent manual inclinometers (Isomed Inc. 975 Sandy Blvd, Portland, USA). The manual inclinometer is a valid and reliable method used to measure range of motion and postural curvatures of the spine. During the measurement process, the feet of the inclinometers were positioned on the spinal protrusions that were identified as corresponding to the first and second thoracic vertebrae (T1/2) and the twelfth thoracic and first lumbar vertebrae (T12/L1). Spinal levels were determined through palpation while the subjects were in a natural standing position.
Measured: 1 week
Visual Analog Scale
Participants' pain intensity was evaluated with the Visual Analog Scale , which consists of a 100 mm long, fixed horizontal line.Visual Analog Scale is considered one of the best available methods that are valid and reliable for estimating pain intensity. Participants were asked to mark the point representing the severity of shoulder pain in their current situation. The Visual Analog Scale score was determined by measuring the end of the line from the left beginning to the point marked by the patient, in millimeters
Measured: 1 week
