To evaluate the possible effects of sex and age on strength–duration time constant (SDTC). The SDTC of 126 healthy volunteers was measured following stimulation of right median nerve at the wrist. Variations in values were evaluated according to sex and age. The SDTC was 438.6 ± 114.5 μs in women an...
