Objective: The aim of this study was to evaluate the effect on spasticity, muscle strength and motor performance after 8 weeks of whole-body vibration training compared with resistance training in adults with cerebral palsy.Methods: Fourteen persons with spastic diplegia (21-41 years) were randomized to intervention with either whole-body vibration training (n=7) or resistance training (n=7). Pre- and post-training measures of spasticity using the modified Ashworth scale, muscle strength using isokinetic dynamometry, walking ability using Six-Minute Walk Test, balance using Timed Up and Go test and gross motor performance using Gross Motor Function Measure were performed.Results: Spasticity decreased in knee extensors in the whole-body vibration group. Muscle strength increased in the resistance training group at the velocity 30 degrees /s and in both groups at 90 degrees /s. Six-Minute Walk Test and Timed Up and Go test did not change significantly. Gross Motor Function Measure increased in the whole-body vibration group.Conclusion: These data suggest that an 8-week intervention of whole-body vibration training or resistance training can increase muscle strength, without negative effect on spasticity, in adults with cerebral palsy.

People with physical disabilities (PD) suffer from consequences due to lack of physical activity and consequently, are at increased risk of chronic diseases. We aimed to evaluate the ability of a motorised assistive device for dynamic standing with weight-bearing in addition to standard state-of-the-art therapy to improve clinical outcome in a meta-analysis of available studies. A total of 11 studies were identified from different European countries analysing the effect of the dynamic device Innowalk. Raw data of nine studies were pooled including a total of 31 patients observed between 2009 and 2017. Standardised questionnaires and physical outcomes were examined in this exploratory meta-analysis. We recorded patients' characteristics, duration, intensity, and location of usage as well as general clinical outcomes and improvement of passive range of motion (PROM). The analysed population consisted in 90% cases of patients younger than 18 years of age. Patients were severely disabled individuals (aged 8 (6-10) years; 58% male; 67% non-ambulatory, 86% cerebral palsy). A total of 94% used the Innowalk in a home-based or day-care setting. For nearly all individuals (94%), improvements were recorded for: walking or weight-bearing transfer ( n = 13), control/strength of the trunk or head ( n = 6), joint mobility ( n = 14), sleep ( n = 4 out of 6/67%), or muscle strength ( n = 17), vital functions ( n = 16), bowel function ( n = 10), attention/orientation ( n = 2). PROM of the hip (flexion, abduction, and adduction) significantly ( p < 0.001 for multiple comparisons) increased after 1 month ( p < 0.05 flexion, adduction) and further after 5 months ( p < 0.05 each) in contrast ( p < 0.05 each) to a control group with state-of-the-art therapy. Similarly, PROM showed a trend towards improvement in dorsal extension of the ankle ( p = 0.07). In summary, this is the first report of a novel device with additional benefit to standard therapy for severe PD. These intriguing results warrant the planned prospective randomised controlled trial to prove the concept and mechanism of action of this device., Competing Interests: Caroline Schmidt-Lucke and Ana Pekanovic are employed by Medico-academic Consultings, Ulrika Skjellvik Tollefsen is employed by Municipality of Asker, Tonje Thon is employed by Municipality of Porsgrunn and Rikke Damkjær Moen is employed by Made for Movement.

Objective: This study aimed to explore the value of individualized feedback on performance, flow and self-efficacy during simulated laparoscopy. Furthermore, we wished to explore attitudes towards feedback and simulator training among medical students., Methods: Sixteen medical students were included in the study and randomized to laparoscopic simulator training with or without feedback. A teacher provided individualized feedback continuously throughout the procedures to the target group. Validated questionnaires and scales were used to evaluate self-efficacy and flow. The Mann-Whitney U test was used to evaluate differences between groups regarding laparoscopic performance (instrument path length), self-efficacy and flow. Qualitative data was collected by group interviews and interpreted using inductive thematic analyses., Results: Sixteen students completed the simulator training and questionnaires. Instrument path length was shorter in the feedback group (median 3.9 m; IQR: 3.3-4.9) as compared to the control group (median 5.9 m; IQR: 5.0-8.1), p<0.05. Self-efficacy improved in both groups. Eleven students participated in the focus interviews. Participants in the control group expressed that they had fun, whereas participants in the feedback group were more concentrated on the task and also more anxious. Both groups had high ambitions to succeed and also expressed the importance of getting feedback. The authenticity of the training scenario was important for the learning process., Conclusions: This study highlights the importance of individualized feedback during simulated laparoscopy training. The next step is to further optimize feedback and to transfer standardized and individualized feedback from the simulated setting to the operating room.

Objective: To investigate how simulator training and non-technical factors affect laparoscopic performance among residents in obstetrics and gynecology., Design: In this prospective study, trainees were randomized into three groups. The first group was allocated to proficiency-based training in the LapSimGyn(®) virtual reality simulator. The second group received additional structured mentorship during subsequent laparoscopies. The third group served as control group. At baseline an operation was performed and visuospatial ability, flow and self-efficacy were assessed. All groups subsequently performed three tubal occlusions. Self-efficacy and flow were assessed before and/or after each operation., Setting: Simulator training was conducted at the Center for Advanced Medical Simulation and Training, Karolinska University Hospital. Sterilizations were performed at each trainee's home clinic., Population: Twenty-eight trainees/residents from 21 hospitals in Sweden were included., Methods/main Outcome Measures: Visuospatial ability was tested by the Mental Rotation Test-A. Flow and self-efficacy were assessed by validated scales and questionnaires. Laparoscopic performance was measured as the duration of surgery. Visuospatial ability, self-efficacy and flow were correlated to the laparoscopic performance using Spearman's correlations. Differences between groups were analyzed by the Mann-Whitney U-test., Results: No differences across groups were detected at baseline. Self-efficacy scores before and flow scores after the third operation were significantly higher in the trained groups. Duration of surgery was significantly shorter in the trained groups. Flow and self-efficacy correlate positively with laparoscopic performance., Conclusions: Simulator training and non-technical factors appear to improve the laparoscopic performance among trainees/residents in obstetrics and gynecology., (© 2013 Nordic Federation of Societies of Obstetrics and Gynecology.)

Objective: To analyze the relationship between visuospatial ability and simulated laparoscopy performed by consultants in obstetrics and gynecology (OBGYN)., Study Design: This was a prospective cohort study carried out at two community hospitals in Sweden. Thirteen consultants in obstetrics and gynecology were included. They had previously independently performed 10-100 advanced laparoscopies. Participants were tested for visuospatial ability by the Mental Rotations Test version A (MRT-A). After a familiarization session and standardized instruction, all participants subsequently conducted three consecutive virtual tubal occlusions followed by three virtual salpingectomies. Performance in the simulator was measured by Total Time, Score and Ovarian Diathermy Damage. Linear regression was used to analyze the relationship between visuospatial ability and simulated laparoscopic performance. The learning curves in the simulator were assessed in order to interpret the relationship with the visuospatial ability., Results: Visuospatial ability correlated with Total Time (r=-0.62; p=0.03) and Score (r=0.57; p=0.05) in the medium level of the virtual tubal occlusion. In the technically more advanced virtual salpingectomy the visuospatial ability correlated with Total Time (r=-0.64; p=0.02), Ovarian Diathermy Damage (r=-0.65; p=0.02) and with overall Score (r=0.64; p=0.02)., Conclusions: Visuospatial ability appears to be related to the performance of gynecological laparoscopic procedures in a simulator. Testing visuospatial ability might be helpful when designing individual training programs., (Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.)

Background: The objective was to study fetal growth parameters in in vitro fertilization (IVF) pregnancies and to investigate the relationship between fetal growth and maternal blood pressure., Methods: We examined 64 women, pregnant after in vitro fertilization, with repeated ultrasound examinations measuring biparietal diameter, femur length, abdominal diameter and fetal weight at 24, 30, and 36 weeks of gestation. We calculated deviations in percent from expected values in regards to biparietal diameter, femur length, abdominal diameter, and fetal weight. Blood pressure was measured every second week., Results: Biparietal diameter in the study group was significantly smaller at 24 (-3.3%, 95%CI -4.4 to -2.2) and 30 (-1.4%; 95%CI -2.5% to -0.3) weeks. Femur length differed significantly on all three occasions, at 24 (-6.3%; 95%CI -7.7 to -5.1), 30 (-6.6%; 95%CI -8.0 to -5.3), and 36 (-3.9%; 95%CI; -5.0 to -2.8) weeks. Abdominal diameter demonstrated a significant deviation at 24 weeks (-1.6%; 95%CI -2.8 to -0.4). Fetal weight did not reach significant deviations at any gestational age. There was no correlation between deviation of the individual growth parameters or estimated fetal weight and elevated blood pressure., Conclusion: The growth pattern of in vitro fertilization pregnancies does not seem to differ from spontaneously conceived pregnancies to any appreciable extent. In the present material, no relationship between fetal growth and maternal blood pressure could be observed. We could not show that an impaired fetal growth predates the development of hypertension.
