Abstract

Objectives: The aim of this study was to analyze differences in affected upper limb functionality (grip strength, digital pinch, sensitivity, and manual dexterity) in women with breast cancer and to determine whether these factors can predict perceived disability. This study highlights the motor and sensory deficits resulting from breast cancer treatments and underscores the need for a comprehensive approach to addressing them. Methods: A descriptive cross-sectional study was conducted with 42 women diagnosed with breast cancer who underwent surgery and received chemotherapy, radiotherapy, or hormonal therapy. Strength, sensitivity, and manual dexterity were assessed, along with pain and disability questionnaires. Results: Significant differences were found in affected upper limb functionality according to age, employment status, and time since surgery. Grip strength, pinch strength, manual dexterity, and sensitivity were identified as predictors of perceived disability, explaining 92.15% of the variance in SPADI scores. Conclusions: Women with breast cancer experience functional deficits in the upper limb, particularly in strength, sensitivity, and manual dexterity. Age, employment status, and time since surgery influence the perceived disability. These findings emphasize the need for comprehensive upper limb evaluations to identify functional deficits and guide personalized rehabilitation strategies.
