Background. The study aims to analyze the relationship between body posture and composition, as well as postural stability in Parkinson’s disease patients. Material and Methods. 32 people were evaluated. The study was conducted in the Laboratory of Posturology at Jan Kochanowski University in Kielce (Poland). Body posture was examined using the optoelectronic body posture Formetric Diers Method III 4D. Postural stability was evaluated using the Biodex Balance System platform. Body composition was assessed with the method of bioelectrical impedance analysis using the Tanita MC 780 MA analyzer. Results. 11 patients (34.37%) had hyperkyphosis, 10 (31.25%) hyperlordosis, and 3 (9.37%) hyperkyphosis-hyperlordosis posture. Scoliosis (>10°) was observed in 28 (87.5%) subjects, whereas 4 (12.5%) presented scoliotic body posture (1–9°). In the examined population, all parameters of postural stability were within normal limits. Conclusions. A significant positive correlation was observed between surface rotation (°), General Stability Index (r=0.4075, p=0.0206), and Anteroposterior Stability Index (r=0.3819, p=0.0310). There was also a significant positive correlation between surface rotation (+max) (°), General Stability Index (r=0.3526, p=0.0206), and Anteroposterior Stability Index (r=0.3873, p=0.0285). Metabolic age also presented a significant positive correlation between metabolic age and General Stability Index (r=0.4057, p=0.0212), as well as Anteroposterior Stability Index (r=0.3507, p=0.0490).
