    The use of SHIMMER to detect stride time in running gait
    Wireless sensing solutions that provide for accurate long term monitoring of walking and running stride characteristics in a real world environment would be an excellent tool for biomechanics researchers. SHIMMER™ is a small, wireless, low-power inertial sensor with a large storage capacity that facilitates wearable wireless sensing in both connected and disconnected modes. It is a very flexible, multi-sensing device, consisting of a tri-axial accelerometer, with options of add-on daughter boards such as tri-axial gyropscopes, or ECG/EMG sensors. The purpose of this study was to compare the performance of the SHIMMER wireless sensor platform for the determination of heel-strike and stride times, across a range of speeds, to a marker-based motion capture system (CODA, Charnwood Dynamics, UK). Previous studies have shown that the SHIMMER sensor and associated algorithms can successfully calculate these parameters in slow to fast walking speeds, but it has not yet been applied to running.

    A common awareness and knowledge platform for studying and enabling independent living – CAPSIL
    The population of the world is growing older, and the balance of old to young is shifting so that by 2050 over 30% of the population is expected to be over 60 years old, with particularly high ratios of old to young in the EU, USA and Japan. CAPSIL is an FP7 Coordinating Support Action that incorporates a strategic international coalition of University and Industrial partners that already have extensive teams developing hardware/software/knowledge solutions to independent living based on user requirements. CAPSIL has two fundamental goals: 1. To carry out an analysis of the state of the art with regards to technology, healthcare and public policy in the EU, US and Japan for enabling independent living for older adults. Based on this analysis, develop a detailed roadmap for EU research to achieve effective and sustainable solutions for independent living 2. To support aging research by proposing procedures to incorporate all of these diverse solutions into WiKi entries (CAPSIL WiKi). It is our hope that these CAPSIL WiKi’s will enable researchers and the ICT industry to get the information they need to quickly and easily test solutions for prolonging independent living within the many and various heterogeneous communities. In this paper we will summarise the principal findings of the CAPSIL Roadmap and present an overview of the main research gaps and recommendations for policy and research development. Finally, we will introduce the CAPSIL WiKi infrastructure.

    Investigating normal day to day variations of postural control in a healthy young population using Wii balance boards
    The quantification of postural control (PC) provides the opportunity to understand the function and integration of the sensorimotor subsystem. The increased availability of portable sensing technology, such as Wii Balance Boards (WBB), has afforded the capacity to capture data pertaining to motor function, outside of the laboratory and clinical setting. However, prior to its use in long-term monitoring, it is crucial to understand natural daily PC variation. Twenty-four young adults conducted repeated static PC assessments over 20 consecutive weekdays, using WBBs. 16/24 participants (eyes open) and 11/24 participants (eyes closed) exhibited statistically significant differences (p <0.05) between their initial ‘once-off’ measure and their daily measures of PC. This study showed that variations in PC exist in a healthy population, a once-off measure may not be representative of true performance and this inherent variation should be considered when implementing long-term monitoring protocols.

    Fatigue : a case for single subject analysis
    Neuromuscular fatigue is relative to the physical capabilities of an individual at a given point in time, and is brought about by a complex combination of central and peripheral factors. Fatigue protocols used in biomechanical research cannot, therefore, be expected to elicit a homogenous response in all research participants. Attempts to establish generalized models for movement outcomes and strategies due to fatigue through descriptive group statistics may therefore be an impractical approach. An alternative approach, single-subject (SS) analysis, may be more appropriate. SS analysis does not imply “case-study” investigation. Rather, it involves an in-depth analysis of individuals to better understand what unique responses, if any, they have in common (Bates, 1996). The aim of this study was to carry out both group and SS analyses on pre- and post- fatigue outcome measures in order to establish how the selected statistical methodology might influence conclusions drawn.

    Validation of a functional fatigue protocol
    Neuromuscular fatigue is believed to be a contributing factor to injury in athletic situations. To examine this idea, it is necessary to establish functional fatigue models that are representative of the type of physical activity that takes place in athletic training and competition. The purpose of this study was to validate a novel functional fatigue protocol (FFP) that reproduces the demands of a sporting situation i.e. accelerating and decelerating the body, changing direction, jumping, landing, and metabolic stress.
