Effectiveness of Oncological Physiotherapy on Painful Shoulder Cervical Ganglion in Head and Neck Cancer

Objective: To estimate whether oncological physiotherapy treatment with neurodynamic and kinesitherapy (passive and active) in patients with "painful shoulder due to accessory spinal nerve dissection" operated on for head and neck cancer is more effective than standard therapeutic exercise therapy with strength. Design: Randomized Clinical Trial (intervention study, no drugs). Two branches of rehabilitative treatment applied by oncological physiotherapist. GROUP I: Treatment of passive and active mobilizations together with neurodynamics techniques. GROUP II (or control group) Current treatment applied as gold standard, consisting of therapeutic strength exercise, which the patient will carry out under the supervision of the physiotherapist. The frequency of both will be twice a week for two months. Study subjects: Participants who underwent cervical ganglion dissection surgery for head and neck cancer, and who have, as a surgical sequela, a painful shoulder due to accessory spinal nerve injury. Determinations: At baseline (t0), at one month (t1m) and at the end (t6m) will be measured, (1) the degree of pain of the participants through the pain scale (EVA), (2) the functionality of the shoulder, with the DASH scale and goniometry, (3) the quality of life with the QLQ H\&N35 questionnaire, (4) the strength with a hand dynamometer and (5) the degree of neurodynamics of the accessory spinal nerve with the neurodynamic test for this nerve.
