Purpose: To evaluate the effectiveness of an evidence‐based 12‐week Tai Chi course designed to improve balance and physical function in a population of older veterans. Methods: Community dwelling veterans of all ages with gait and balance problems were invited to participate in the Tai Chi program. Participants completed the Berg Balance Scale (BBS), the Timed Up and Go (TUG) test, and the Falls Efficacy Scale‐International (FES‐I) at baseline and again at the end of the program. Descriptive statistics were used to summarize study participants' characteristics. The change from baseline to the end of the 12‐week program was calculated for each of the three primary outcome variables (BBS, TUG, FES‐I). Results: Twenty‐two veterans, aged 58 years and above, with perceived gait and/or balance issues were enrolled in the program with completion by 11 veterans. Veterans who completed their final assessments showed the BBS, improved significantly (p = 0.004) from baseline to the 12‐week assessment. The TUG scores improved by a median of 1.3 s (p = 0.022). There was not a significant change in the FES‐I. Conclusions: Preliminary findings provide evidence of the effectiveness of a 12‐week Tai Chi program to improve functional outcomes for older veterans with mild to moderate gait and balance problems.

Purpose: The purpose of this nurse‐led project was to increase the number of interprofessional Tai Chi instructors for veterans through a 5‐week (32 hours) training of trainers (ToT) course led by a Tai Chi master trainer. Methods: This project was designed to evaluate the effectiveness of using the ToT model to increase the availability of Tai Chi to veterans. To understand how well the ToT course met learners' needs, a two‐phase course evaluation was conducted. Results: Fifteen interprofessional employees enrolled in and completed the course. Most learners were white (67%) females (67%) with a median age of 50 years. All agreed that the training provided the skills, materials, and confidence to lead Tai Chi classes. Most (93%) indicated experiencing positive health benefits from the training and none experienced any negative effects. The 3‐month follow‐up evaluation indicated that 10 (67%) were teaching veterans in individual or group classes with two others assisting. Twelve instructors taught more than 150 veterans. Conclusions: Overall, learners evaluated this ToT course positively and indicated their needs were met and felt prepared to teach Tai Chi despite being inexperienced. The course was a success with 80% of new instructors teaching or coteaching Tai Chi to veterans. [ABSTRACT FROM AUTHOR]

Background/objective: Balance problems are common in older adults with Alzheimer's disease (AD). The objective was to study the effects of a Wii-Fit interactive video-game-led physical exercise program to a walking program on measures of balance in older adults with mild AD.Methods: A prospective randomized controlled parallel-group trial (Wii-Fit versus walking) was conducted in thirty community-dwelling older adults (73±6.2 years) with mild AD. Home-based exercises were performed under caregiver supervision for 8 weeks. Primary (Berg Balance Scale, BBS) and secondary outcomes (fear of falls and quality of life) were measured at baseline, 8 weeks (end of intervention), and 16 weeks (8-weeks post-intervention).Results: At 8 weeks, there was a significantly greater improvement (average inter-group difference [95% CI]) in the Wii-Fit group compared to the walking group in BBS (4.8 [3.3-6.2], p < 0.001), after adjusting for baseline. This improvement was sustained at 16 weeks (3.5 [2.0-5.0], p < 0.001). Analyses of the secondary outcome measures indicated that there was a significantly greater improvement in the Wii-Fit group compared to walking group in Activity-specific Balance Confidence scale (6.5 [3.6-9.4], p < 0.001) and Falls Efficacy Scale (-4.8 [-7.6 to -2.0], p = 0.002) at 8 weeks. However, this effect was not sustained at 16 weeks. Quality of life improved in both groups at 8 weeks; however, there were no inter-group differences (p = 0.445).Conclusion: Home-based, caregiver-supervised Wii-Fit exercises improve balance and may reduce fear of falling in community-dwelling older adults with mild AD.

The purpose of this study was to evaluate a multi-component method for capturing nutrient intake, which used observation, photography, and an innovative computer program. To assess reliability and accuracy, multiple responsible employees (REs) independently conducted nutrient intake assessments on simulated meals; each RE's results relating to energy intake were compared to those from the other REs and to those obtained by pre- and post-meal weighing of the food items. System efficiency was assessed by having REs perform independent assessments on the same set of simulated meals using either the new or traditional hospital method for which the REs had to document each food item served and then find the items in a computer database--steps that were automated in the new method. Interrater reliability for energy intake estimated on clinic wards was excellent (intraclass correlation coefficient = 0.975, 95% CI 0.958 to 0.992) and there was a high level of agreement between the REs' estimates and the true values determined by food weighing; per the method of Bland and Altman the mean difference between the two types of estimates was 0.3 kcal (95% CI, [ABSTRACT FROM AUTHOR]

Obtaining a detailed assessment of a hospitalized patient's nutrient intake is often critically important to ensuring the patient's successful recovery. However, this process is often laborious and prone to error. Inaccurate nutrient intake assessments result in the inability of the healthcare team to recognize patients with developing nutritional deficits that contribute to delayed recovery and prolonged lengths of stay. This paper describes an innovative, easy to use system designed to increase the precision of calorie count reports by using a combination of photography, direct observation, and a specially developed computer program. Although the system was designed specifically for use in a Department of Veterans Affairs Hospital, it has the potential to be adapted for use in other hospital environments. [ABSTRACT FROM AUTHOR]

Our work identifies subjects based on their height and the distance between their joints. Using a depth sensing camera, we obtained the position of a person's joints in 3D space relative to each other. The distances between adjacent joints and height of a subject's head are used to create a vector of eight features for an individual to use for identification. Using modified KNN, full and partial feature sets were used to identify subjects. Additionally, our classifier can be utilized to assess ambulation (such as walking's velocity and distance) of subject, when identified.

Compared to the traditional method, energy intake assessments could be completed using the multi-component method in less than a third of the time. These results indicate the multi-component method is an accurate, reliable, and efficient method of obtaining energy intake assessments for hospitalized patients., Competing Interests: The funding sponsors had no role in the design of the study; in the collection, analyses, or interpretation of data; in the writing of the manuscript, and in the decision to publish the results.
