BEHAVIOURAL TESTING OF SENSORI-MOTOR FUNCTION IN AWAKE CRANIOTOMY; A LITERATURE REVIEW

Abstract AIMS Evaluate how sensori-motor (SM) testing is performed in awake craniotomy (AC) the literature. Compare SM methods and their related outcomes. METHOD Literature search from 1995- 2019 OVID Medline, Embase, PsychInfo, CINAHL Web Of Science using all permutations of MESH terms “brain tumour” “awake craniotomy” “sensory” “motor” “testing”. 11671 articles were screened 28 included based on suffcient detail tasks intraoperative processes that would allow for evaluation. RESULTS used to preserve function AC when tumours involve or neighbour eloquent cortical structures sub serving movement. It also identify subcortical tracts such as corticospinal frontostriatal, well negative motor network. There broad variation conducted different centres, with no standardisation. The most common strategies were: •Simple gross movement contralateral limbs (n= 17) e.g., hand open/closing. •Functional (n=5) grasping object •Standardised tests 3) including Hand Manipulation Task Sensory-Motor Profile •Patient at rest observed positive responses patient reported sensory changes 2). CONCLUSIONS Multiple intra-operative exist preservation craniotomy. Benefits over-arching strategy frequently demonstrated. However, comparison optimisation between hindered by heterogenous study objectives outcomes reported. A core outcome set may be useful standardise, optimise compare so maximal benefit functional can achieved.
