“…This resulted in a reduction of the forces the subjects applied and thereby lowered risks of suture breakage. Alternatively, haptic feedback is provided via vibrations of the master device 16 or via actuators stimulating the user's fingertips 17 . This way, the illusion of holding an object in hand is created.…”

Robot assisted surgery (RAS) provides medical practitioners with valuable tools, decreasing strain during surgery and leading to better patient outcomes. While the loss of haptic sensation is a commonly cited disadvantage of RAS, new systems aim to address this problem by providing artificial haptic feedback. N = 56 papers that compared robotic surgery systems with and without haptic feedback were analyzed to quantify the performance benefits of restoring the haptic modality. Additionally, this study identifies factors moderating the effect of restoring haptic sensation. Overall results showed haptic feedback was effective in reducing average forces (Hedges’ g = 0.83) and peak forces (Hedges’ g = 0.69) applied during surgery, as well as reducing the completion time (Hedges’ g = 0.83). Haptic feedback has also been found to lead to higher accuracy (Hedges’ g = 1.50) and success rates (Hedges’ g = 0.80) during surgical tasks. Effect sizes on several measures varied between tasks, the type of provided feedback, and the subjects’ levels of surgical expertise, with higher levels of expertise generally associated with smaller effect sizes. No significant differences were found between virtual fixtures and rendering contact forces. Implications for future research are discussed.

BACKGROUND: It is unclear how accurately students can reproduce specific forces that are often required for physical examination maneuvers. This study aimed to determine the baseline accuracy of force application for preclinical medical students, evaluate the effectiveness of a quantitative visual feedback intervention, and investigate whether certain demographics influence accuracy. MATERIALS AND METHODS: First- and second-year medical students were enrolled and demographic data were collected. Students blindly applied their estimation of 15 lbs (6.8 kg), 3 lbs (1.4 kg), 10 lbs (4.5 kg), 1.5 lbs (0.7 kg), and 6 lbs (2.7 kg) of force on a scale. Visual feedback training was then performed wherein students applied a series of additional forces unblinded five times, and then blindly administered the same five initial forces 12 minutes and one week later. Accuracy was compared at each time point and a regression analysis was evaluated for predictors of accuracy. RESULTS: Thirty-three students participated. The mean baseline accuracy was 38.3%, 41.1% immediately following intervention, and 35.6% one week later (P = 0.66). Accuracy was significantly higher at higher intended forces compared to lower forces (P < 0.05). The number of prior occupations was a positive independent predictor (P = 0.04), and the number of sports played was noted to be a negative predictor (P = 0.01), of baseline accuracy. CONCLUSIONS: Medical students’ ability to accurately reproduce clinically relevant forces is poor. There is a clear need to implement a robust training program in medical education, and students may need multiple training sessions to refine this skill.
