The purpose of this study was to determine the reliability
and validity of two smartphone applications: (1) GetMyROM - inclinometery-based
and (2) DrGoniometry - photo-based in the measurement of active shoulder external
rotation (ER) as compared to standard goniometry (SG). PARTICIPANTS: Ninety-four
Texas Woman's University Doctor of Physical Therapy students from the School of
Physical Therapy - Houston campus, were recruited to participate in this study.
MATERIALS/METHODS: Two iPhone applications were compared to SG using both novice
and experienced raters. Active shoulder ER range of motion was measured over two
time periods in random order by blinded novice and experienced raters. RESULTS:
Intra-rater reliability using novice raters for the two applications ranged from
an intraclass correlation coefficient (ICC) of 0.79 to 0.81 with SG at 0.82.
Inter-rater reliability (novice/expert) for the two applications ranged from an
ICC of 0.92 to 0.94 with SG at 0.91. Concurrent validity (when compared to SG)
ranged from 0.93 to 0.94. There were no significant differences between the
novice and experienced raters. CONCLUSION: Both applications were found to be
reliable and comparable to SG. A photo-based application potentially offers a
superior method of measurement as visualizing the landmarks may be simplified in
this format and it provides a record of measurement. CLINICAL RELEVANCE: Further
study using patient populations may find the two studied applications are useful
as an adjunct for clinical practice.
