Since trunk function plays a major role in propulsion in sit-skiers and athletes belonging to distinct classes have different abilities to control trunk muscles, the aim of this study is to evaluate how athletes personalized their skiing strategy to compensate their impairment and improve skiing effectiveness. Sixteen Paralympic sit-skiers belonging to different classes volunteered as participant. Each athlete executed two double poling tests on a ski ergometer at the maximal speed he/she can reach and the best, identified as the fastest, was considered in the analysis. A set of two passive reflective markers was used for kinematic analysis: the first marker was placed on the athlete shoulder, while the second was placed on the sledge in correspondence of the hip joint. A Vicon motion capture system with 8 cameras was used to collect the athlete's motion during the double poling tests. Forces were recorded by sensors attached to the pulling cables. For the analyses athletes were grouped concerning to the individual impairment level into: group A (LW10-LW10.5), group B (LW11-LW11.5), and group C (LW12). Per each athlete the trunk maximal forward and trunk maximal backward, the range of motion, the start and finish time of trunk movement with respect to the beginning of the poling phase were measured during each cycle, and the time between the start and the finish of trunk movement were calculated. The main results of this study were: 1) greater trunk flexion and range of motion for group C compared to group A; 2) group A started trunk movement earlier compared to group C; 3) no differences in range of motion timing. Since greater trunk flexion and range of motion allow generating higher propulsion force with low level of fatigue, it is possible to conclude that thanks to their ability in control trunk muscles athletes in group C can develop a skiing strategy which is more effective than athletes that cannot control abdominal and lumbar extensor muscles

Many amputees suffer from irritation and wounds as a result of poor residual limb volume management. Reasons contributing to failure to maintain volume properly include peripheral neuropathy, cognitive impairment, and social/cultural issues. Amputees commonly use socks of various thicknesses to account for diurnal limb volume loss. However, data relating to sock compliance is lacking due to an absence of a reliable way to collect usage data. A device was fabricated utilizing wireless RFID and socket-limb interface force detection technology to track sock usage and activity of an amputee. Pilot data was collected through both in-lab and out-of-lab protocols. The collected data showed encouraging results tracking interface force data, however accurate sock data collection was difficult. Suggested solutions include designing a more effective antenna and using the interface force data to detect limb presence to start a tag accumulator algorithm. Clinical applications for the Sock Monitor include intervention through alerting the amputee of a need for a sock change before tissue damage occurs and evidence for prosthetists to justify insurance reimbursement for components and socket replacements. The next step is to use a new prototype with better hardware and firmware to collect real-world usage data from a large group of amputees. A predictive model will be made and implemented to determine if intervention in sock usage improves comfort and limb tissue health.
