Sponsor's own description

Patients with head and neck cancer and undergo neck dissection often suffer from spinal accessory nerve dysfunction (e.g. shoulder droop, shoulder pain, and decreased active range of motion (AROM) of the shoulder joint and scapular muscle strength), even the spinal accessory nerve is preserved during surgery. Abnormal muscle activities of scapular muscles, including upper trapezius (UT), middle trapezius (MT), lower trapezius (LT), serratus anterior (SA) and rhomboid were reported in subsequent research articles. Particularly for the trapezius muscle, the decreased amplitudes were observed even after 9 months of neck dissection. It has been reported that conscious correction of scapular orientation during arm movement could increase trapezius muscle activities, and motor control training could change scapular kinematic such as increased posterior tilt and upward rotation during arm movement.
