Perceptions of ability among adults with upper limb absence: impacts of learning, identity, and community.

Aims: The purpose of this research was to examine the lived experiences of adults with upper limb absence, specifically the interplay of device use, ability, and quality of life through semi-structured interviews. We sought to draw insight from these experiences to improve the practice and perceptions of adults with upper limb absence, prosthetists, and technology designers.Methods: Semi-structured interviews were conducted and interpreted with phenomenological analysis for fourteen individuals with acquired or congenital limb absence. Through an interpretive phenomenological analysis approach, researchers employed an inductive approach to coding and identification of central themes.Results: Participants shared high perceptions of ability and function, regardless of prosthesis or assistive technology use. Life experiences related to three dimensions strongly influenced perceptions of ability: (1) learning to live with upper limb absence, (2) developing their identity, and (3) connecting with their community. The diversity of experiences across participants highlighted the limitations of identifying "normative" pathways of recovery or device use, emphasizing the need for flexible and adaptable systems that can creatively support personal goals and needs.Conclusions: Integration of novel platforms for professional practice, supportive communities, and technology innovation can support the evolving needs and care of individuals with upper limb absence.Implications for rehabilitationIn this study, perceptions of ability were largely independent of prosthetic use and each individual developed a unique toolkit of devices and strategies to support function in daily life.Clinicians can support perceptions of ability by promoting opportunities for community development and life-long learning.Informal communities, such as online networks, can provide novel device designs, resources for learning, and societal awareness to empower individuals with limb absence.

Design and Real-World Evaluation of Eyes-Free Yoga: An Exergame for Blind and Low-Vision Exercise.

People who are blind or low vision may have a harder time participating in exercise due to inaccessibility or lack of encouragement. To address this, we developed Eyes-Free Yoga using the Microsoft Kinect that acts as a yoga instructor and has personalized auditory feedback based on skeletal tracking. We conducted two different studies on two different versions of Eyes-Free Yoga: (1) a controlled study with 16 people who are blind or low vision to evaluate the feasibility of a proof-of-concept and (2) an 8-week in-home deployment study with 4 people who are blind or low vision, with a fully functioning exergame containing four full workouts and motivational techniques. We found that participants preferred the personalized feedback for yoga postures during the laboratory study. Therefore, the personalized feedback was used as a means to build the core components of the system used in the deployment study and was included in both study conditions. From the deployment study, we found that the participants practiced Yoga consistently throughout the 8-week period (Average hours = 17; Average days of practice = 24), almost reaching the American Heart Association recommended exercise guidelines. On average, motivational techniques increased participant's user experience and their frequency and exercise time. The findings of this work have implications for eyes-free exergame design, including engaging domain experts, piloting with inexperienced users, using musical metaphors, and designing for in-home use cases.

Nutritional composition and digestibility by ocelots (Leopardus pardalis) of whole animals and a commercial diet.

Felids are adapted to eat whole prey, but in North American zoos are usually fed processed diets based on muscle meat. We analyzed proximate nutrient composition and digestibility by ocelots of a commercial processed diet and whole animals of five species. The processed diet did not differ significantly from the whole animals in proximate composition, although it was at one end of the range of results for all nutrients. Domestic chicks were significantly lower than all other dietary items tested in digestibility of energy and fat, and lower than rabbits and quail in digestibility of dry matter. There were no other significant differences. These results suggest that the commercial diet tested provides an appropriate nutritional environment for ocelots with respect to proximate constituents. Studies of vitamin and mineral composition and digestibility and comparisons to wild prey species should be conducted to permit a full evaluation.

Awareness of genital health in young male athletes.

OBJECTIVE: To assess young male athletes' understanding of the need for a genital examination during the sports physical, their knowledge of signs and symptoms of serious testicular pathology, and the type of genital protection they wear for specific sports. Additionally, to identify common sport-specific genital injuries requiring emergency department treatment. DESIGN: Descriptive survey. SETTING: Station-based mass screening preparticipation physical exams performed in northeastern Ohio. PARTICIPANTS: A total of 755 male athletes at the junior high school, high school, and collegiate levels (age 12-25 years). MAIN OUTCOME MEASUREMENTS: Participants' answers to a 5-question survey. Male genital injury occurring in common contact and collision sports identified from the National Electronic Injury Surveillance System. RESULTS: Fifty percent did not understand why the genital examination is done. Forty-seven percent did not wear genital protection during sports. Most were unaware of the risk of testicular cancer and did not appreciate the difference in urgency of seeking medical treatment of painless versus painful testicular swelling. Approximately 20% of emergency department visits for sports-related genital trauma had a risk of permanent injury, and up to 7% resulted in hospitalization or transfer. CONCLUSIONS: Young male athletes are unaware of testicular pathology that affects their age group, and many do not wear genital protection during sports. Better education of young males regarding genital health and protection is necessary.
