Validity and Reliability of iPhone Application in Internal Rotation Measurement
Condition: Shoulder Pain
MeSH terms: Shoulder Pain
Study type: Interventional

Summary: 
      The validity and reliability of active internal rotation ROM measurement of shoulder with
      smartphone in patients with shoulder pain was investigated.
    

Detailed description: 
      Eighteen patients with shoulder pain who applied to the Physical Medicine and Rehabilitation,
      shoulder subspecialty outpatient clinic who agreed to participate in the study and 18
      volunteers who had not experienced shoulder pain before enrolled in the study. Participant
      age range was determined as 40-70 years.

      The IHandy® app is a free app with a visual display similar to that of the digital
      inclinometer in terms of digital size. In this study, due to its prevalence in the literature
      and its use in clinics, manual goniometer (gold standard) was chosen to be compared with this
      iPhone application.

      The participants were asked to lie on the bed in supine position with shoulder to be measured
      at the edge of the bed. The measured shoulder was positioned at 90 degrees abduction, 90
      degrees elbow flexion and forearm at neutral position. The participant was asked to bring the
      wrist closer to the bed in the direction of the little finger, and was measured at the angle
      that the shoulder could not move without lifting the arm. In the measurement made with the
      application, the phone was held parallel to the ulna and the value displayed on the screen
      was recorded. The participant were asked to repeat the movement if his/her shoulder lift up
      of bed, straightened his/her elbow, or did anything that would disrupt her movement pattern.

      Each measurement was repeated 3 times and after 2 weeks the control measurements were made by
      repeating 3 times.

      Measurements were conducted separately in different cabinets without seeing each other for
      each participant by 1 physical medicine and rehabilitation specialist and 1 physiotherapist.
      The measurements were recorded in separate locations until all participants were completed.
    

Intervention name(s): iHandy application; Standard Goniometer
Intervention type(s): Diagnostic Test; Diagnostic Test
Intervention description(s): The IHandy® app is a free app with a visual display similar to that of the digital inclinometer in terms of digital size. In this study, due to its prevalence in the literature and its use in clinics, manual goniometer (gold standard) was chosen to be compared with this iPhone application.; While measuring with goniometer, the pivot point of the goniometer was placed on the olecranon, the immobile rod of the goniometer was kept parallel to the bed, while the moving rod was kept parallel to the ulna, the angle was recorded at the end point of the movement.
Allocation: Randomized
Intervention model: Parallel Assignment
Intervention model description: Measurements were conducted separately in different cabinets without seeing each other for each participant by 1 physical medicine and rehabilitation specialist and 1 physiotherapist. The measurements were recorded in separate locations until all participants were completed.
