Table 8: Spearman correlation coefficients (rs) for the relationship between the tipstim® parameters and the motor coordination parameters. The conducted analysis showed no correlation between the tipstim(r) parameters--median and ulnar sensation and the parameters of motor coordination, both for the measurement without stabilization and with stabilization.
