Proprioceptive neuromuscular facilitation in the functionality and lymphatic circulation of the upper limb of women undergoing breast cancer treatment

Abstract

Background: With the increase in survival of women treated for breast cancer, it is necessary to evaluate the effect of therapeutic resources on co-morbidities resulting from the surgical treatment of the disease. The aim of this study was to evaluate the effects of proprioceptive neuromuscular facilitation on the functionality and lymphatic circulation of the upper limb involved in the treatment of breast cancer.

Methods: The study was conducted according to randomized clinical trial design. Thirty-two women at a mean age of 52.20 (±8.32) years, submitted to breast cancer treatment, divided into two groups, control - women submitted to standard breast cancer treatment, and treated group, composed of women who underwent breast cancer treatment and rehabilitation with the proprioceptive neuromuscular facilitation technique. Palmar grip strength with dynamometer and shoulder range of motion with goniometer were evaluated. Lymphatic circulation analysis was performed in a computerized scintillation chamber, before and after therapeutic intervention.

Findings: In the results obtained, a significant increase (p < 0.05) of palmar grip strength was observed, a significant increase in range of motion of flexion (p < 0.001), extension (p < 0.0012), abduction (p < 0.0001), external rotation (p < 0.0001), internal rotation (p < 0.0001), and not significant for lymphatic flow (p > 0.05).

Interpretation: The results obtained in this study allow us to conclude that proprioceptive neuromuscular facilitation favors an increase in muscle strength, range of motion, but not in lymphatic flow, in women undergoing surgical treatment for breast cancer.
