Biological feedback for support reaction and changing of its depth in the rehabilitation of patients after radical mastectomy

Abstract

Objective. The study deals the influence of different biofeedback (BFB) depth for support reaction on the performance of a short course (3 sessions) for a motor-cognitive training of static and dynamic types in the rehabilitation of patients after a radical mastectomy. Subjects and methods. 21 patients between the ages of 40 and 74 years after radical mastectomy for breast cancer (BC) were examined and performed rehabilitation with the BFB depth for support reaction with a change normal sensitiveness of the force platform by 15, 30, 45 and 60 %. The 1st group included aged 40–54 patients, and the 2nd group included aged 57–74 patients. Results and conclusion. It was found that after 3 courses of the motor-cognitive training of dynamic type (“Lights”), conditionally “younger” patients showed an increase of their results from the fi rst to the third session in all four variants of the changing BFB depth (15, 30, 45, 60 %) from the normal sensitiveness of the force platform. These results weren’t found in dynamics in the 2nd group of patients. Data from static training (“Target”) shows that changing of the BFB depth in the range from 15 to 60 % don’t affect the results of exercises in both groups throughout 3 sessions. These types of training for older patients weren’t as effective as for younger patients over such a short period. Probably, these results of dynamic training depend on multitasking and learning difficulties. The obtained results should be taken into account when a training plan will be drowned up because the incorrect selection of the BFB depth and the short period of medical rehabilitation will reduce the eff ect of training.
