The impact upper extremity impairments (UE) have on UE function in breast cancer
survivors (BCS) is unclear. The purpose of this study was to evaluate the
associations between upper extremity active range of motion (AROM), passive range
of motion (PROM), and strength with self-reported function in BCS. BCS (n = 24)
completed the Disabilities of Arm, Shoulder and Hand (DASH) and the Pennsylvania
Shoulder Score (PSS). AROM and PROM of shoulder flexion, extension, external
rotation (ER) at 0 degrees and 90 degrees of abduction, and internal rotation
(IR) at 90 degrees of abduction were measured using a digital inclinometer.
Strength was measured using a hand-held dynamometer for scapular abduction and
upward rotation, scapular depression and adduction, flexion, IR, ER, scaption,
and horizontal adduction. All constructs of AROM, PROM, and strength were
correlated with the DASH and PSS. DASH was moderately to highly correlated with 2
of 5 AROM, 2 of 5 PROM, and 6 of 7 shoulder strength measures. PSS was moderately
to highly correlated with 2 of 5 AROM, 2 of 5 PROM, and 4 of 7 shoulder strength
measures. Regression analysis showed that AROM explained 40% of the DASH scores
and strength explained 20% of scores on the PSS. This study characterizes the
impact that shoulder motion, flexibility, and strength losses have on shoulder
function in BCS. Deficits in AROM and shoulder strength explained the greatest
proportion of shoulder disability. Future clinical trials should consider
incorporating AROM and strengthening techniques to improve shoulder use after
breast cancer treatments.
