  Purpose

The purpose of this study is to determine the test-retest and inter-rater reliability and concurrent validity of two iPhone goniometric applications in the measurement of active shoulder external rotation as compared to a standard manual goniometer. The scientific hypotheses for this study are as follows:

  1. There will be significant Pearson correlations (>.8) to demonstrate test-retest reliability for each of the tools between the 1st and 2nd round of testing as assessed by novice testers.
  2. There will be significant intra-class correlation coefficients (>.8) to demonstrate inter-rater reliability between the novice tester and the experienced tester for each of the three tools.
  3. There will be significant Pearson correlations (>.8) to demonstrate concurrent validity between the standard goniometer and the photo capture application, the standard goniometer and the accelerometer-based application and the photo capture application with the accelerometer-based app. as assessed by novice testers.

Primary Outcome Measures:
  • Active Shoulder External Rotation Range of Motion
    Range of Motion will be collected via two iPhone applications and a standard goniometer.


Enrollment: 94
Study Start Date: January 2012
Study Completion Date: March 2012
Primary Completion Date: January 2012 (Final data collection date for primary outcome measure)
Groups/Cohorts
Normals
Texas Woman's University students from the School of Physical Therapy - Houston campus will be recruited to participate in this study. The participant will be excluded if they have pain in the shoulder on the day of testing, less than 90 degrees of active or passive shoulder abduction, less than 90 degrees of active or passive elbow flexion, have had any previous surgeries or procedures to either shoulder or identify by self-report any reason that they should not perform active external rotation at the shoulder.
