Focal Muscle Vibration and Physical Exercise in Postmastectomy Recovery: An Explorative Study

Background. Physical activity initiation and maintenance are particular challenges in the postmastectomy recovery and in particular Dragon Boat racing seems to be a useful sport activity. The aim of this study was to evaluate the role of focal muscle vibration as a proprioceptive input to improve upper limb functioning in a group of "paddlers" patients. Methods. A group of paddlers has been evaluated before vibratory treatment (T0), immediately after therapy (T1), after one week (T2), and after one month (T3) with DASH questionnaire, Body Image Scale, McGill pain questionnaire, Constant Scale, and Short Form 36 questionnaire. Results. Fourteen patients showed a significant reduction in disability score (p = 0,001) using DASH scale, an improvement of upper limb function (p = 0,001) using the Constant scale, and a reduction of pain (p = 0,007) at the McGill pain questionnaire. The Mental Composite Score of the Short Form 36 questionnaire showed significant results (p = 0,04) while no significant results had been found regarding the physical mental score (p = 0,08). Conclusion. Focal muscle vibration may be a useful treatment in a postmastectomy recovery of upper limb functionality.
