Introduction: Older adults are defined by a series of characteristics that include chronological age, change in social environment and changes in functional ability. Everything that hinders physical activity contributes to the decrease of the range of motion. The most common causes of decreased motion in older adults are disorders of the musculoskeletal system and the entire nervous system. Purpose: The purpose of the diploma work was to assess the effect of age, gender and dominance on the passive range of motion of the shoulder joint in older adults. Methods: The research included 63 subjects, 48 women and 15 men, aged 65 years or over. The average age of the subjects was 80.9 (7.2) years. In order to check the correlation between the measurements of motion and the age, we calculated the correlation coefficient. We compared the measured values of passive motion according to gender and dominance. The threshold of significance was set at p < 0.05. Results: With the measurements, we also proved that the passive range of motion of the shoulder joint in older adults, aged 65 - 95 does not decreases with age in the same way with all movements in the shoulder joint. In the right shoulder girdle, we determined a statistically significant (p = 0.006) low and negative correlation (rho = -0.35) by external rotation and age. In the left shoulder girdle between age and elevation through ante flexion (p = 0.02; rho = -0.295) and elevation through abduction (p = 0.003; r = -0.264), we identified statistically significant, low and negative correlation. Between external rotation and age (p = 0.0008; rho = -0.426), we identified statistically significant, moderate and negative correlation. There was a statistically significant difference on internal rotation, according to the gender. We did not prove statistically significant differences, according to the dominance. Between pain and passive range of motion we identified statistically significant correlation in left shoulder girdle in movement elevation through ante-flexion (p = 0.04; rho = -0.340) and elevation through abduction (p = 0.01; rho = -0.37). Discussion and conclusion: Our findings have shown that age-related loss of range of mobility is quite specific for the direction of movement. The latter could be related to different patterns of routine use of the shoulder girdle in daily life and presence of pain.
