Objective. To evaluate musele function of patients on hemodialysis before and after HD sessions also compare to subjective global assessment and bioelectrical impedance parameters.
Material and methods. 37 patients on hemodialysis were studied. Handgrip strength was measured three times with a dynamometer before and after hemodialysis sessions on the non-fistula side and the highest value was used for analysis. Handgrip values were compared with norms and data were divided into groups (normal, weak and very strong muscle strength). We studied the relationship between handgrip strength and nutritional assessment. Bioelectrical impedance parameters (BMI, skeletal muscle mass, lean body mass, protein levels, body cell mass, percentage of body fat mass and waist circumference) were also examined. SPSS was used for statistics.
Results. Before hemodialysis 22 patients (59.46%) demonstrated normal muscle strength, very strong - 4 (10.81%), weak - 11 (29.73%) patients; after hemodialysis normal force showed 20 patients (54.04%), very strong - 2 (5.41%), weak - 15 (40.45%). No relationship between nutritional status and handgrip strength before hemodialysis, but there was a significant correlation (p<0.05) between nutritional status and handgrip strength after hemodialysis. Positive correlation between skeletal muscle mass, lean body mass, protein level, body cell mass and handgrip strength and no connection between BMI, percentage of body fat mass and waist circumference.
Conclusions. Muscle function decreased after hemodialysis. Handgrip strength may be used as a reliable nutritional marker in hemodialysis patients, measured after HD sessions. We observed relationship between handgrip strength and nutritional status, bioelectrical impedance parameters too.
