Women with fibromyalgia’s experience with three motion-controlled video game consoles and indicators of symptom severity and performance of activities of daily living

Purpose: Little is known of Motion-Controlled Video Games (MCVGs) as an intervention for people with chronic pain. The aim of this study was to explore the experience women with fibromyalgia syndrome (FMS) had, using commercially available MCVGs; and to investigate indicators of symptom severity and performance of activities of daily living (ADL). Method: Of 15 female participants diagnosed with FMS, 7 completed a program of five sessions with Nintendo Wii (Wii), five sessions with PlayStation 3 Move (PS3 Move) and five sessions with Microsoft Xbox Kinect (Xbox Kinect). Interviews were conducted at baseline and post-intervention and were supported by data from observation and self-reported assessment. Results: Participants experienced play with MCVGs as a way to get distraction from pain symptoms while doing fun and manageable exercise. They enjoyed the slow pace and familiarity of Wii, while some considered PS3 Move to be too fast paced. Xbox Kinect was reported as the best console for exercise. There were no indication of general improvement in symptom severity or performance of ADL. Conclusion: This study demonstrated MCVG as an effective healthcare intervention for the women with FMS who completed the program, with regards to temporary pain relief and enjoyable low impact exercise.

• Implications for Rehabilitation

• Exercise is recommended in the management of fibromyalgia syndrome (FMS).

• People with FMS often find it counterintuitive to exercise because of pain exacerbation, which may influence adherence to an exercise program.

• Motion-controlled video games may offer temporary pain relief and fun low impact exercise for women with FMS.

目的 为满足呼吸防护用品的适配性设计和测试需求,根据目前我国成年人头面测量数据提出2种新的分类(栏)方式:二元分栏和主成分分栏,并分析2种分栏对我国成人头面划分的适用性.方法 以近期我国3000名成年人头面尺寸测量数据为基础建立头面尺寸数据库,根据头面尺寸指标脸长-脸宽的二维分布提出我国成年人头面二元分栏.采用主成分分析对10项稳定的头面尺寸指标(最小额宽、脸宽、鄂宽、脸长、瞳孔间距、头宽、鼻突长、鼻宽、鼻梁宽、鼻长)分析后提出我国成年人头面主成分分栏.通过我国成年人头面数据在不同分栏的分布比例分析两类分栏对成人头面划分的适用性.结果 我国成年人头面二元分栏和主成分分栏分别将脸型分为10个型号和8个型号.总覆盖率分别为96.9%(男性95.4%,女性98.4%)和96.5%(男性95.1%,女性98.1%).各型号覆盖比例较为均匀,二元分栏各型号覆盖率在4.6%～21.7%之间,主成分分栏各型号覆盖率在10.4%～14.6%之间.对比分析国外头面分栏方法,美国洛斯阿拉莫斯实验室(LANL)全面罩分栏只能覆盖我国70.9%的人群,且各型号覆盖极不均匀,其中3个型号的覆盖率之和不足1%;美国国家职业安全卫生研究所(NIOSH)研制的二元分栏和主成分分栏能覆盖我国96.4%和95.9%的人群,但各型号分布不均匀,其二元分栏中5个型号仅覆盖6.3%的人群,主成分分栏中3个型号的覆盖率之和为7.2%.结论 根据我国成人头面数据提出的二元分栏和主成分分栏能代表国人头面尺寸分布,比国外分栏更适用.     

Clinical evaluation of all-ceramic crowns fabricated from intraoral digital impressions based on the principle of active wavefront sampling

Objectives

The aim of the present study was to compare the fit of all-ceramic crowns fabricated from intraoral digital impressions with the fit of all-ceramic crowns fabricated from silicone impressions.

Methods

Twenty patients agreed to take part in the study to receive two Lava™ crowns each for the same preparation. One crown was fabricated from intraoral scans using the Lava™ Chairside Oral Scanner (Lava C.O.S.), and the other crown from a two-step silicone impression. Prior to cementation the fit of both crowns was clinically evaluated by two calibrated and blinded examiners; the marginal fit was also scored from replicas. Data from the replica scores were analysed by Anderson–Darling test, Levene's test and Mann–Whitney test. All tests were performed with α-level of 0.05.

Results

Median marginal gap in the conventional impression group was 71 μm (Q1:45 μm; Q3:98 μm), and in the digital impression group 49 μm (Q1:32 μm; Q3:65 μm). Mann–Whitney test revealed a significant difference between the groups (p < 0.05). No differences were found regarding the occlusion, and there was a trend for better interproximal fit for the digitally fabricated crowns.

Conclusions

1.

Crowns from intraoral scans revealed significantly better marginal fit than crowns from silicone impressions.

2.

Marginal discrepancies in both groups were within the limits of clinical acceptability.

3.

Crowns from intraoral scans tended to show better interproximal contact area quality.

4.

Crowns from both groups performed equally well with regard to occlusion.

     

Nintendo Wii rehabilitation (“Wii-hab”) provides benefits in Parkinson's disease

Parkinson's disease (PD) impairs both activities of daily living (ADLs) and motor function and has adverse effects on mood in many patients. While dopaminergic medications are quite helpful for motor and ADLs impairments in PD, complementary therapies are also important in helping patients achieve maximum benefits and quality of life. We hypothesized that the Nintendo Wii (Wii) is a useful tool in improving motor and non-motor aspects in patients with PD, given its ability to drive functional movements and interactive nature. We enrolled twenty subjects with early to mid-stage PD in an open-label within-subjects study design where each subject was evaluated at baseline and then re-evaluated after playing the Wii three times per week for four weeks. Subjects were then re-evaluated one month later after not playing the Wii for a month to see if effects carried over. Subjects demonstrated significant improvements in the primary outcome measure (Nottingham Extended Activities of Daily Living Test (NEADL)), quality of life (PDQ-39) and motor function (UPDRS), and a trend toward improved mood (HAM-D) after four weeks of Wii therapy. Follow-up assessments one month later showed continued improvement for quality of life and UPDRS scores. The results demonstrate that Wii therapy provides short-term motor, non-motor, and quality of life benefits in PD. Further studies are needed to determine if there are long-term benefits of Wii therapy in PD.     

Lifespan data on postural balance in multiple standing positions

BackgroundMaintaining balance is important throughout life. The Nintendo Wii Balance Board (WBB) can give reliable quantitative measures of postural balance, but reference data are lacking. Furthermore, one-leg standing balance across the adult lifespan is not fully described. The aim of the study was (1) to provide reference data on postural balance in multiple standing positions using a WBB, (2) to determine an age cut-off for the ability to stand on one-leg in men and women.MethodsThis was a cross-sectional study and data was collected in two cities in Denmark (Aalborg and Odense) and Norway (Oslo and Ålesund) during spring and summer of 2016.Postural balance was assessed in individuals across the adult lifespan in three different bases of support positions (hip-wide and narrow two-legged stance, and one-legged stance) using a WBB. Reference data were analyzed and presented in 10-year intervals.ResultsA total of 354 individuals aged 20–99 years were recruited. Reference data were presented in percentiles stratified by gender for the following age categories: 20–29, 30–39, 40–49, 50–59, 60–69, 70–79, and 80+. Data showed that the difference between men and women’s balance was larger at older age with men performing worst. The cut-off ability to stand on one-leg was 72.5 years without statistical evidence of gender difference.ConclusionThis study reports reference data for postural balance across the entire adult lifespan using a WBB. More than half of the individuals over 72.5 years of age were unable to stand balanced on one-leg.

Validity of the revised Impact on Family (IOF) scale

OBJECTIVE: To assess psychometric properties of the revised 15-item Impact on Family (IOF) Scale. STUDY DESIGN: A secondary analysis of items using data collected from 252 parents during an earlier randomized clinical trial. RESULTS: Exploratory factor analysis and confirmatory factor analysis identified a single factor with factor loadings similar to that of IOF developers. The one factor accounts for 45.7% of the sample variance. An Item Response Theory analysis found that 11 of the 15 items had alpha values greater than 1.00, with good to excellent item characteristic and item information curves. The test information and measurement error curves for the entire IOF were excellent. Construct validity of the IOF also was supported. Parent IOF scores correlated in the expected directions with maternal mood (r = -0.50), sibling behavior problems (r = -0.35), and severity of illness (r = 0.31) and were associated with family socioeconomic status (t = -4.5, all P < .001). CONCLUSIONS: This study provides independent support for validity and reliability of the revised IOF scale. This scale is a promising, easy-to-use instrument for the measurement of impact of illness and disability on families of children with chronic illness or disability.
