Study Summary
The goal of this project is to test our central hypothesis that changes in sex hormone concentration result in changes to the basic elements of motor control - at multiple levels, from the musculotendinous unit to motor control circuitry. Under Aim 1 the investigator will determine the influence of sex hormone fluctuations on the muscle stretch reflex during active and passive states, and the time lag between hormone concentration changes and the reflex response. The investigator will use a technically simple assessment that could be implemented in the field. Under Aim 2 the investigator will determine the influence of sex hormone fluctuations on spinal motor neuron excitability using H-reflex as a probe and the simultaneous change in the muscle mechanics using muscle twitch response. Aims 1 \& 2 will include a focus on the differential role of oral contraceptives. In Aim 3 the investigator will use paired-pulse transcranial magnetic stimulation during active contraction to determine the influence of sex hormone fluctuation.
Primary Outcome
The conditioned motor evoked potential (MEP) at each inter-stimulus interval (ISI) was normalized to MEP obtained from unconditioned stimulation. Change was evaluated by regressing the normalized conditioned motor evoked potential amplitude at each ISI with estradiol concentration. Average and standard deviation for each ISI reported.
