Objective:
The aim of the study was to investigate the effects of vibration therapy to home-based exercises on shoulder muscle strength, range of motion, pain-related disability, and muscles viscoelastic properties of shoulder and neck in patients with breast cancer undergoing radiotherapy.
Design:
This randomized controlled superiority trial was conducted with 38 participants who underwent breast cancer surgery. All patients were randomized into two groups: control group and vibration group. Both groups performed home-based exercises for 5 days a week for 6 wks. Vibration group received additional vibration therapy for 2 days a week for 6 wks. Shoulder range of motion, muscle strength, pain, disability, grip strength, and viscoelastic properties of the pectoralis major, upper trapezius, and sternocleidomastoid were compared before and after intervention.
Results:
Vibration group demonstrated better improvement in shoulder range of motion, muscle strength, and pain-related disability ( P < 0.05), except for internal rotation range of motion. Only tone of pectoralis major was significantly higher in vibration group according to group x time interaction ( P < 0.05), no differences were detected in terms of muscle viscoelastic properties in the control group patients ( P > 0.05).
Conclusions:
Vibration therapy provided superior improvements in muscle strength, range of motion, and pain-related disability compared to home-based exercises alone in patients with breast cancer undergoing radiotherapy in the early postoperative phase.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
