Telerehabilitation systems have the potential to enable therapists to monitor and assist stroke patients in achieving high-intensity upper extremity exercise in the home environment. We adopted an iterative user-centred approach, including multiple data sources and meetings with end-users and stakeholders to define the user requirements for home-based upper extremity rehabilitation using wearable motion sensors for subacute stroke patients. We performed a requirement analysis consisting of the following steps: 1) context & groundwork; 2) eliciting requirements; 3) modelling & analysis; 4) agreeing requirements. During these steps, a pragmatic literature search, interviews and focus groups with stroke patients, physiotherapists and occupational therapists were performed. The results were systematically analysed and prioritised into "must-haves", "should-haves", and "could-haves". We formulated 33 functional requirements: eighteen must-have requirements related to blended care (2), exercise principles (7), exercise delivery (3), exercise evaluation (4), and usability (2); ten should-haves; and five could-haves. Six movement components, including twelve exercises and five combination exercises, are required. For each exercise, appropriate exercise measures were defined. This study provides an overview of functional requirements, required exercises, and required exercise measures for home-based upper extremity rehabilitation using wearable motion sensors for stroke patients, which can be used to develop home-based upper extremity rehabilitation interventions. Moreover, the comprehensive and systematic requirement analysis used in this study can be applied by other researchers and developers when extracting requirements for designing a system or intervention in a medical context. This study provides an extensive overview of user requirements for home-based upper extremity rehabilitation using wearable motion sensors in stroke patients. These requirements can be used as a basis for developing home-based UE telerehabilitation interventions. Including these requirements may facilitate the clinical implementation of such telerehabilitation systems. The comprehensive and systematic approach used in this sudy can be applied by other researchers and developers when extracting requirements for designing a system or intervention in a medical context.

The purpose of this study was to describe the prevalence, incidence and risk factors for climbing-related injuries of the upper extremities in recreational climbers. A total of 426 recreational climbers were recruited from indoor climbing halls. The baseline questionnaire included questions on potential risk factors for climbing injuries: personal factors, climbing-related factors and upper extremity injuries that had occurred in the previous 12 months. Follow-up questionnaires collected information on new injuries that occurred during the follow-up period. The incidence of climbing-related injuries during one-year follow-up was 42.4% with 13 injuries per 1 000h of climbing. The finger was the most frequently affected injury location (36.0%). The following risk factors were associated with the occurrence of upper extremity injuries: higher age (OR 1.03, 95%CI 1.01;1.05), performing a cooling-down (OR 2.02, 95%CI 1.28;3.18), climbing with campus board (OR 2.48, 95%CI 1.23;5.02), finger strength middle finger (OR 1.12, 95%CI 1.05;1.18) and previous injuries (OR 3.05, 95%CI 2.01 ;4.83). Climbing injuries of the upper body extremities are very common among recreational climbers in indoor halls and several risk factors can be identified that are related to a higher injury risk.

Young male soccer players have been identified as a target group for injury prevention, but studies addressing trends and determinants of injuries within this group are scarce. The goal of this study was to analyze age-specific trends in hospital-treated upper extremity fractures ( UEF) among boys playing soccer in the Netherlands and to explore associated soccer-related factors. Data were obtained from a national database for the period 1998-2009. Rates were expressed as the annual number of UEF per 1000 soccer players. Poisson's regression was used to explore the association of UEF with the number of artificial turf fields and the number of injuries by physical contact. UEF rates increased significantly by 19.4% in boys 5-10 years, 73.2% in boys 11-14 years, and 38.8% in boys 15-18 years old. The number of injuries by physical contact showed a significant univariate association with UEF in boys 15-18 years old. The number of artificial turf fields showed a significant univariate association with UEF in all age groups, and remained significant for boys aged 15-18 years in a multivariate model. This study showed an increase of UEF rates in boys playing soccer, and an independent association between artificial turf fields and UEF in the oldest boys. [ABSTRACT FROM AUTHOR]
