---|---|---|---|---|
Primary | Intraoperative maximum grip strength (KgF) baseline | Maximum grip strength (KgF) will be measured using hand-held dynamometry every 2 minutes from the time the patient awakes until the end of surgery. Intraoperative maximum grip strength baseline is defined as the mean of 3 consecutive measures with <10% variability. | 1 day | |
Primary | Intraoperative maximum grip strength (KgF) variability | To validate the use of hand-held dynamometry as an adequate tool to monitor intraoperative motor function during awake craniotomies (AC), maximum grip strength (KgF) will be measured every 2 minutes from the time the patient awakes to the end of surgery. The intra-individual variability will be defined as the percent difference between sets with 10% or greater defined as substantial variability. | 1 day | |
Primary | Maximum grip strength (KgF) variability from preoperative baseline | To validate the use of hand-held dynamometry as an adequate tool to monitor intraoperative motor function during AC, each patient will be baselined (mean of 6 consecutive measurements) during the preoperative neuropsychology evaluation. Variability from preoperative baseline will be calculated as a percentile [ (Preoperative Baseline/ Intraoperative Baseline)/ Preoperative Baseline) * 100] | 1 day | |
Primary | Operative Time (Minutes) | Defined as the duration of the procedure from the initiation of skin incision to the completion of skin closure according to anesthesia records. Measured in minutes. | 1 day | |
Secondary | Correlation Coefficient (?) between hand-held dynamometry and manual motor testing during AC | Concordance between hand-held dynamometer and manual motor testing will be evaluated using Spearmans' correlation coefficient. | 1 day | |
Secondary | Postoperative Maximum Grip Strength (KgF) | Postoperative Maximum Grip strength (KgF) will be measured using hand-held dynamometer at day 1 and at 1 month follow-up. | 1 month |
