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° and 90° of abduction, and internal rotation (IR) at 90° 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.
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 13 February 2015.
All research outputs
#31,228,668
of 34,410,798 outputs
Outputs from Physiotherapy Theory & Practice
#1,223
of 1,358 outputs
Outputs of similar age
#309,110
of 340,532 outputs
Outputs of similar age from Physiotherapy Theory & Practice
#9
of 12 outputs
Altmetric has tracked 34,410,798 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,358 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 7.0. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 340,532 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 12 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
