Thrombolysis will continue to be the mainstay for acute stroke treatment, despite the recent revolution in neurointerventional clot retrieval. However, as there are ongoing limitations of thrombolysis of bleeding risk and reduced efficacy in large clots – what possible therapeutic advancements can complement or act as an adjuvant to thrombolysis? Neurointervention – effective, but limited […]

The concept of grouping subjects for randomization is called cluster randomized trials (CRT) – this concept is becoming increasingly common when randomizing large groups. However, when CRTs involve interventions at a cluster level, informed consent from participants may not always be possible to obtain. As informed consent is a fundamental ethical requirement for clinical trials, […]

An ongoing study in Australia is showing how computer games can help patients recovering from strokes, brain injuries, amputations and other conditions. The study is the largest trial of its kind to utilize computer gaming technology in rehabilitation. The George Institute’s Professor Cathie Sherrington is leading this study that is testing a wide range of […]
