简要总结
Breast cancer-related lymphedema (BCRL) is a common complication affecting the upper extremity following breast cancer treatment. This study aims to investigate the relationship between lymphedema severity and shoulder joint function and muscle activation patterns in breast cancer survivors.

结局指标
主要结局
Shoulder joint mobility
时间窗: baseline
shoulder flexion, abduction, external rotation and extension range of motion measured using a digital inclinometer.
Muscle activation patterns (Amplitude)
时间窗: baseline
Surface EMG recording of muscle activation patterns (amplitude) of the biceps brachii, anterior/middle/posterior deltoid, pectoralis major and latissimus dorsi during shoulder elevation. Amplitude will be reported in units of microvolts (µV)
Muscle activation patterns (Timing)
时间窗: baseline
Surface EMG recording of muscle activation patterns (timing) of the biceps brachii, anterior/middle/posterior deltoid, pectoralis major and latissimus dorsi during shoulder elevation. Timing will be reported in units of milliseconds (ms).
次要结局
- Shoulder abductor strength(baseline)
- Self-reported upper extremity function(baseline)
- Shoulder flexors strength(baseline)
