Abstract Introduction Virtual Reality (VR) training is becoming an increasingly popular form of exercise aiding in re-education of body balance. Many reports have demonstrated its effectiveness, greater patient involvement in exercise and better outcomes compared to traditional rehabilitation [1]. The aim of this study was to assess the impact of the additional training in VR on body balance in patients after total hip replacement. Material and Methods 56 patients randomly assigned to an experimental group (30 people) and a control group (26 people) was included in the study. All patients had undergone THR within 2 to 12 weeks before the beginning of the study. The control group underwent standard post-operative rehabilitation, while a VR training programme was used in the experimental group as an additional rehabilitation tool. Balance was assessed with the VBC system and the AMTi AccuSway plate. The results were considered significant for p <0.05. Results CoP displacement in the frontal plane was reduced in both groups in tests with eyes closed (p<0.05). Other parameters in standing tests remain the same. The maximum forward deflection test has shown a significant increase in the range of forward movement in the experimental group (p <0.05). In the control group, the duration of the forward movement phase was reduced, but the range remained the same. The rhythmic sway test showed an increase in the average speed of movements in the experimental group (p <0.05). There were no changes in the control group. Conclusions 1. Postural stability training in VR primarily involves dynamic aspects of the maintenance of balance. 2. Improvement in functional tests may indicate a better clinical outcome of rehabilitation in patients who have additionally trained in VR. 3. The improvement obtained in static tests most probably results from improvement in muscle strength and static stability resulting from the rehabilitation.

AbstractThe surgical approach for total hip replacement (THR) depends on surgeon preference or the preference and experience of the surgeon with a specific approach. The aim of this study was to analyze the learning curve of the direct anterior approach (DAA) using the cumulative summation test for learning curve (LC-CUSUM). A retrospectively collected database of 400 THRs using the DAA (January 2010–September 2014) at a single center by a single surgeon. The learning curve was analyzed by determining the duration of surgery, blood loss, and number of complications. All 400 primary THRs were reviewed. Based on the LC-CUSUM, duration of surgery, and surgical failure, the learning curve plateau was achieved after the 19th surgery and the curve follows a substantially negative trend. The average duration of surgery changed significantly for the first hundred (78 minutes) to the last hundred (61 minutes). A significant decrease in blood loss was observed as well. A total of 17 (4.25%) complications occurred, with reduction of the complication rate as surgeons' experience increases. The authors' study did not show the long learning curve as previously described in the literature. The number of complications was small, and there was a significant decrease in duration of surgery, blood loss, and number of complications as surgeon's experience increases. The authors suggest that the educational environment of a teaching hospital, combined with the use of the DAA as a standard approach for all primary THRs and supervision of experienced surgeons, contribute to the favorable learning curve with a low complication rate.
