Shoulder hand behind back (HBB) range of motion (ROM) is a useful measure of
impairment and treatment outcome. The purpose of this repeated measures study was
to identify inter- and intra-rater reliability, of a new simplified method of
measuring HBB ROM. Two experienced raters measured HBB ROM with a bubble
inclinometer on 25 people (aged 42-75 years, 14 female) with unilateral shoulder
dysfunction and 25 age- and gender-matched asymptomatic subjects on two different
occasions. Statistical analysis included calculation of intra-class correlation
coefficients (ICCs), minimal detectable change (MDC), standard error of
measurement (SEM), Pearson correlation coefficient (r), coefficient of
determination (R(2)), and the lower bound score. Mean HBB ROM was 108.6 degrees
(SD = 16.3) and 23.9 degrees (SD = 10.5) on the pain-free and symptomatic side,
respectively. Both intra-rater and inter-rater reliability were high (ICC >
0.80). For asymptomatic people the SEM was at most 3 degrees and MDC was 8
degrees with a strong correlation between the dominant and nondominant sides (r > 0.72). The mean absolute values and lower bound scores were at most 10.2 degrees
and 26.0 degrees , respectively. These results indicate that this new and novel
method of measuring HBB ROM is accurate, has good inter- and intra-rater
reliability, and provides normal values for between-limb ROM variability.
