Previous research has shown that people with complete
cervical spinal cord injury (quadriplegia) commonly report sleep disturbances,
have delayed REM latency and lack endogenous melatonin
production. It is unclear if these findings are related. The aim of this
study was to investigate whether nightly supplementation of 3 mg melatonin
would induce, shift the phase of and/or modify subjective sleep
for people with complete quadriplegia
