Objective:
To evaluate and compare the effectiveness of different methods used for nutritional assessment of outpatients who had hemiplegic stroke.
Methods:
A cross-section study with adult and elderly patients of both genders enrolled in a rehabilitation center. The analyzed variables were anthropometric measurements, bioelectrical impedance, hand grip strength and thickness of the adductor pollicis muscle. The Pearson χ2 test was used to check the association between variables with a significance level of α = 5%.
Results:
When evaluating the association between indicators of muscle mass, it was observed that the hand grip strength in both genders was positively correlated with arm muscle circumference (p = 0.0196) and lean mass (p = 0.0002). Fat mass measured by the bioelectrical impedance method already showed a significant inverse relationship with the grip (r = -0.3879). The thickness of the adductor pollicis muscle showed significant association with lean mass (p = 0.0052) and hand grip (p = 0.0024).
Conclusion:
In this study, the hand grip strength and thickness of the adductor pollicis muscle were well correlated with measurements determined by anthropometry and bioimpedance. The results show the applicability of grip strength and thickness of the adductor pollicis muscle in clinical practice as nutritional assessment methods for this population, especially elderly patients, since they detect functional changes not captured by other parameters in the short term and are important for early identification of risk nutrition.
