A single sequence of intermittent hypoxia does not alter stretch reflex excitability in able-bodied individuals

The study examined the connection between acute intermittent hypoxia (AIH) and stretch reflex pathways that could potentially lead to spasticity. It specifically looked at the effect of a single exposure to AIH on the sensitivity and excitability of the stretch reflex in muscles of healthy, able-bodied individuals. The results showed no significant change in reflex excitability, meaning there was no evidence that a single session of AIH caused any changes that would lead to spasticity.
