noun
- The minimum time required for an electric current of twice the rheobase strength to stimulate a nerve or muscle tissue.
Usage: medical; physiology; technical
Examples
- The chronaxy of the nerve was measured to determine the optimal stimulation parameters.
- Clinicians use chronaxy values to set appropriate pulse durations for electrical stimulation therapy.
- The chronaxy test helps assess neuromuscular excitability in patients with nerve damage.
- Different tissues have different chronaxy values, which must be considered in pacemaker design.
