Physiological evaluation of the Calgary adapted aRm ergometer (CARE) concussion exertion test in adolescent athletes: A repeated‐measures observational study

Experimental Physiology, EarlyView.
Abstract Exertion testing helps inform exercise prescription during concussion recovery. The Calgary Adapted aRm Ergometer (CARE) test, developed as the first upper‐body specific exertion test, aims to improve accessibility and inclusivity in concussion care.

Cerebrovascular regulation during heat stress

Experimental Physiology, EarlyView.
Abstract Given that the brain is a highly metabolic organ and is enclosed by the skull, effective regulation of cerebral blood flow (CBF), not only for oxygen and nutrients supply but also as a means of convective heat exchange, is critical for preventing excessive elevations in brain temperature.

The effectiveness and cost-effectiveness of ultrasound locating devices for central venous access: a systematic review and economic evaluation [PDF]

, 2003
Background: Approximately 200,000 central venous access (CVA) procedures are performed annually in the NHS. CVA has traditionally been achieved by the landmark method of passing the needle along the anticipated line of the relevant vein using ...

Cerebral blood flow regulation, central arterial stiffness and traumatic brain injury: Effects of aerobic exercise training

Experimental Physiology, EarlyView.
Abstract Advanced age is the strongest risk factor for Alzheimer's disease and related dementias (ADRDs). Traumatic brain injury (TBI) has also been recognized as a risk factor for ADRD, potentially contributing to an earlier onset of the disease. Thus, elucidating the mechanisms underlying brain ageing and TBI is critical for developing strategies to ...
