AB We recruited 102 breast cancer survivors at a secondary care in Malaga. Included breast cancer survivorsshowed a good upper limb functionality but a reduced forearm muscle activity. Forearm muscle activity showeda poor significant correlation with the cancer-related fatigue . Handgrip strength also showed a poor correlationwith the upper limb functionality. Both outcomes tended to lower values with higher levels of cancer-relatedfatigue.Introduction/Background: Breast cancer survivors (BCS) frequently show upper limb dysfunctions. The forearmmuscle activity measured by surface electromyography (sEMG) in this population has not been studied. This studyaimed to describe forearm muscle activity in BCS, as well as to assess its possible relationship with other variablesrelated to upper limb functionality and cancer-related fatigue (CRF). Materials and Methods: A cross-sectional studywas carried out including 102 BCS as volunteers at a secondary care in Malaga, Spain. BCS were included if theywere aged between 32 and 70 years old, without evidence of cancer recurrence at the time of recruitment. The forearmmuscle activity (microvolts, μV) was assessed by sEMG during the handgrip test. The handgrip strength was assessedby dynamometry (kg), the upper limb functionality (%) was measured by the upper limb functional index (ULFI) question-naire and the CRF was also assessed by revised Piper Fatigue Scale (0-10 points). Results: BCS reported reducedforearm muscle activity (287.88 μV) and reduced handgrip strength (21.31 Kg), a good upper limb functionality (68.85%),and a moderate cancer-related fatigue (4.74). Forearm muscle activity showed a poor significant correlation (r = –0.223,P = .038) with the CRF. Handgrip strength showed a poor correlation with the upper limb functionality (r = 0.387, P <.001) and age (r=-0.200, P = .047)...
