“…Except for the first session, a pattern emerged in which SL and gait velocity decreased on the first block of trials compared to the last block from the prior session, but reached higher levels by the last block of trials of the current session. A warm-up effect, either physiological [26] or psychological [27] could account for this initial decrease in performance evident in the first block of trials. During the first session, SL decreased from the second to the third block.…”

We examined intensive walking practice using two instructional strategies on gait in Parkinson's disease (PD) before and after training and on delayed retention tests. During four training sessions (15 practice trials of walking per session), subjects (N = 6 per group) were given either verbal instruction (VI) to "take a big step" or VI plus augmented feedback (FB). For FB, videotape performance-feedback (from prior trial) supplemented by performance-cues (for subsequent trial) was given after each trial. On pre- and posttests (1 week after training), the only instructions were to "walk as well as you can." For available subjects (N = 7), retention was tested at 3, 6, or 12 months after training. Gait parameters were derived from kinematic analysis of walking during training and testing. From pre- to posttests, stride length, walking velocity and shoulder excursion increased significantly, with no change in cadence. Improvements in stride length and gait velocity above pretest levels were maintained on retention tests. During training and testing, no effects of VI versus VI + FB were found. Although the two instructional strategies did not differ, intensive practice walking with VI improved the gait pattern of individuals with PD and these gait improvements were maintained over an extended period of time.

Background Pre-operative simulation “warm-up” has been shown to improve performance and reduce errors in novice and experienced surgeons, yet existing studies have only investigated conventional laparoscopy. We hypothesized a brief virtual reality (VR) robotic warm-up would enhance robotic task performance and reduce errors. Study Design In a two-center randomized trial, fifty-one residents and experienced minimally invasive surgery faculty in General Surgery, Urology, and Gynecology underwent a validated robotic surgery proficiency curriculum on a VR robotic simulator and on the da Vinci surgical robot. Once successfully achieving performance benchmarks, surgeons were randomized to either receive a 3-5 minute VR simulator warm-up or read a leisure book for 10 minutes prior to performing similar and dissimilar (intracorporeal suturing) robotic surgery tasks. The primary outcomes compared were task time, tool path length, economy of motion, technical and cognitive errors. Results Task time (-29.29sec, p=0.001, 95%CI-47.03,-11.56), path length (-79.87mm, p=0.014, 95%CI -144.48,-15.25), and cognitive errors were reduced in the warm-up group compared to the control group for similar tasks. Global technical errors in intracorporeal suturing (0.32, p=0.020, 95%CI 0.06,0.59) were reduced after the dissimilar VR task. When surgeons were stratified by prior robotic and laparoscopic clinical experience, the more experienced surgeons(n=17) demonstrated significant improvements from warm-up in task time (-53.5sec, p=0.001, 95%CI -83.9,-23.0) and economy of motion (0.63mm/sec, p=0.007, 95%CI 0.18,1.09), whereas improvement in these metrics was not statistically significantly appreciated in the less experienced cohort(n=34). Conclusions We observed a significant performance improvement and error reduction rate among surgeons of varying experience after VR warm-up for basic robotic surgery tasks. In addition, the VR warm-up reduced errors on a more complex task (robotic suturing) suggesting the generalizability of the warm-up.
