There are few research studies that have assessed the hazard detection (HD) challenges of experienced, skilled drivers. This paper presents the pilot study results of an HD training program, Commercial Driver Assessment and Training System (CDATS), developed for commercial motor vehicle (CMV) drivers. The training involved simulation-based videos that highlight potential vehicle, pedestrian, and visually hidden hazards during unprotected intersection maneuvers: left-turn, right-turn, and straight-thru. Low-fidelity driving simulations were designed to reinforce video lessons and increase the expectation and detection of potential hazards. Training efficacy was assessed using a driving simulator HD task presented to short-haul CMV drivers ( N = 16) at pre-/post-assignment to CDATS training or a control condition. Results suggested that CMV drivers had highest HD task accuracy (% correct) for vehicle hazards and lowest accuracy for visually hidden hazards. Performance for pedestrian hazards was dependent on the intersection maneuver, with performance decreases for left-turn, right-turn and straight-thru intersections, respectively. Post-test results suggested overall HD improvement in the CDATS training group with no change in the control group; however, there was no significant change in relative hazard type by intersection maneuver pattern. Similar to prior research, experienced CMV drivers may also exhibit challenges in HD, particularly for visually hidden and visible pedestrian hazards, and may benefit from HD training.

Older drivers are overrepresented in intersection crashes primarily because they fail to scan for potential threat vehicles after they enter a stop-controlled intersection. Existing simulator-based older driver training programs double the frequency of secondary glances that older drivers take up to two years after training. However, the simulator sickness dropout rate for this training is 40%. Two contributing factors to simulator sickness are 1) configuration of the driving simulator, and 2) duration of continuous simulator training. In this experiment, 91 older drivers were assigned to one of five groups: 3 simulator training groups, one passive training group, and one control group. Simulator training sessions were broken into segments of only 30-45 s in length. The effectiveness of the training was evaluated in the field. The most effective training was on a 3 screen simulator which doubled the frequency of secondary glances in the field and reduced simulator drop-out rates to 14.3%.

Three tank gunnery trainers were studied to determine learning transfer over repeated trails. Devices included the TOPGUN trainer, a part-task, reduced-fidelity tank gunnery trainer; the Videodisk Gunnery Trainer (VIGS), another part-task, limited-fidelity trainer; and the Conduct-of-Fire Trainer (COFT), a full-fidelity trainer. The objective was to determine the degree of gunnery skills transfer between the part-task gunnery trainers and the full-fidelity simulator. COFT criterion performances were examined for two pretraining groups (either TOPGUN first, then VIGS, or VIGS first, then TOPGUN) and a control group in order to determine which pretraining sequence leads to better performance. Each training group, composed of 20 subjects, received two multiple-mission engagement trials on four consecutive days (2 VIGS-2 TOPGUN, or vice versa) before COFT transfer. Results showed significant Group and Trial effects for transfer between TOPGUN and VIGS and significant transfer to COFT performance regardless of the prior sequence of training.

Research consistently demonstrates that attainment of a driver’s license and access to a vehicle directly and favorably influence employment outcomes, enhance one’s ability to capitalize on quality jobs, and expand one’s access to community and independent opportunities. This study used a driving simulator to provide driving lessons to 12 young adults with intellectual disabilities (IDs). The purpose was to use a safe learning environment to screen candidates for those who showed the potential to obtain a driver’s license. Instruction was provided using a set of interactive exercises focusing on controlling the vehicle via lane keeping, speed maintenance, and obstacle avoidance tasks. Results revealed that simulator training provided a safe learning environment to identify individuals demonstrating the potential to safely operate a motor vehicle. Participants demonstrated moderate to large gains in maintaining lane position, speed, braking response, and target detection. Implications and suggestions for future research are provided.

Background: Whiplash-Associated Disorders (WAD) are common following a motor vehicle accident. The Functional Impairment Test - Hand, and Neck/Shoulder/Arm (FIT-HaNSA) assesses upper extremity physical performance. It has been validated in patients with shoulder pathology but not in those with WAD. Objectives: Establish the Intra and inter-rater reliability and the known-group and construct validity of the FIT-HaNSA in patients with Grade II WAD (WAD2). Methods: Twenty-five patients with WAD2 and 41 healthy controls were recruited. Numeric Pain Rating Scale (NPRS), Neck Disability Index (NDI), Disabilities of the Arm, Shoulder and Hand (DASH), cervical range of motion (CROM), and FIT-HaNSA were completed at two sessions conducted 2 to 7 days apart by two raters. Intraclass correlation coefficients (ICC) were used to describe Intra and inter-rater reliability. Spearman rank correlation coefficients (ρ) were used to quantify the associations between scores of the FIT-HaNSA and other measures in the WAD2 group (convergent construct validity). Results: The Intra and inter-ICCs for the FIT-HaNSA scores ranged from 0.88 to 0.89 in the control group and 0.78 to 0.85 in the WAD2 group. Statistically significant differences in FIT-HaNSA performance between the two groups suggested known group construct validity (P < 0.001). The correlations between the NPRS, NDI, DASH, CROM and FIT-HaNSA were generally poor (ρ < 0.4). Conclusion: The study results indicate that the total FIT-HaNSA score has good Intra and inter-rater reliability and the construct validity in WAD2 and healthy controls.

Abstract Background Part of patients undergoing TKA did not achieve the expected physiological function results. The purpose of this study was to investigate whether preoperative balance training can reduce pain and improve joint function after TKA.Methods 100 patients with knee osteoarthritis (OA) prepared for TKA, according to the inclusion and exclusion criteria, were randomly divided into balance training group (50 patients) and control group (50 patients). The main evaluation outcomes of the study included early functional milestones, ROM, WOMAC score, keen society score (KSS), KOOS score, and complications at 1 month (baseline) and 1 day before surgery, 6 weeks (main endpoint) and 52 weeks (1 year) after surgery.Results 4 patients lost to follow-up at 1 month before surgery, 96 received planned surgery and 86 underwent a complete postoperative evaluation. After TKA, many indicators of the two groups, including WOMAC score, KSS, KOOS score, were significantly improved compared with before surgery. At 52 weeks after TKA, no statistically significant difference between the balance training group and control group in attain early functional milestones, ROM, WOMAC score, KSS, KOOS score, and complications; however, at 6 weeks after surgery, balance training group had better early benefits in stopping all narcotics (P = 0.045), relieving pain (P = 0.037), improving function (P = 0.017) and quality of life (QOL) (P = 0.028).Conclusions Although there were no difference between preoperative balance training group and control group at the 52 weeks after surgery, however, preoperative balance training can relieve pain and improve function in the early stage (6 weeks), but adequately statistically powered trials are needed to confrm the accuracy of the study resultsTrial Registration ChiCTR2000032789.

Background: The effect of aqua training on human body composition still causes inconsistency. Objectives: This study was set to identify the effects of WATERinMOTION (WiM) as a water-based exercise on anthropometric and body composition variables without dietetic supervision in overweight/obese, sedentary elderly men. Methods: Participants (n = 70; age: 70.5 ± 4.4 years) derived by purposive and accessible selection were randomly distributed to either a one-month WiM aqua training group (n = 35, two weekly sessions each included 55 minutes on WiM aqua training) or a control group (n = 35, at the same time in sitting state). Anthropometric measures (height, weight, and waist circumference [WC]) and body composition variables (body mass index [BMI], fat mass [FM], total body water [TBW], and free fat mass [FFM]) were evaluated pre/post-study. Results: Upon analysis, statistically significant changes (P ≤ 0.05) were set on weight, BMI, and FM by comparing pre/post study for the WiM group. Furthermore, comparing groups at post disclosed a significant change in anthropometric measures (weight and WC) and body composition variables (BMI, FM, TBW, and FFM). Conclusions: A short-run, non-diet-supervised WiM program suggests supporting a loss in weight, FM, and BMI in overweight/obese, sedentary elderly men.
