Reliability of a New Lower-Extremity Motor Coordination Test

Introduction. Motor coordination is a basic motor ability necessary for daily life, which also allows athletes to win a sports rivalry and patients to assess their recovery progress after therapy and rehabilitation. The aim of the present study was to assess the reliability of a new lower-extremity rate of movements test and testing apparatus.

Material and methods. The study sample consisted of 92 students aged 19.21 ± 3.55 years, with body height of 171.2 ± 15.11 cm and body mass of 66.01 ± 12.32 kg. The study used a test-retest method.

Results. The correlation between the test and the retest was r_s = 0.79 (p < 0.001) for the right leg, and r_s = 0.78 (p < 0.001) for the left leg. In both cases a positive linear correlation was observed (r_s > 0).

Conclusions. The results of the study showed that the new rate of movements electronic testing apparatus was highly valid and reliable. Its technical possibilities eliminate errors that might have occurred earlier during manual counting of the performed cycles of movements.
