The Impact

Abstract Introduction: Physiotherapeutic rehabilitation is used to optimize functional recovery following a distal radial fracture. Being the most common upper limb fracture in all age groups, the DRF peaks in young men and in post-menopausal women with an incidence ratio of 1:4. To date, however, work on leap motion control based rehabilitation of patients with distal radius fracture is limited. This research aims to assess the efficacy of immersive virtual reality in patients with DRF. Methods: In an experimental study, subjects (n = 40) with DRF will be recruited. The participants will be enrolled into either an experimental or control group with 1:1 allocation ratio. Following the primary assessment and allocation, the participants in the experimental group will receive both leap motion control and conventional therapy over a period of 6-week. Participants in the conventional group would undergo only conventional therapy. Throughout the treatment duration and following 6 weeks, daily living activity performance, the hand function and mental status will be assessed in the form of questionnaires.Discussion: The goal of this experimental study is to examine the impact of leap motion control after DRF on improving the functional activity and in turn quality of life. Conclusion: To conclude, this research seeks to examine the rapid and long term effects of leap motion control in DRF patients. The study findings would help prospective patients with DRF, which may include a newly designed approach to rehabilitation.

AbstractThe conceptualisations of matrix, fracture and fissure porosity are important for understanding relative controls on storage and flow of groundwater, and the transport of solutes (and non-aqueous phase liquids) within chalk aquifers. However, these different types of porosity, rather than being entirely distinct, represent elements in a continuum of void sizes contributing to the total porosity of the aquifer. Here we define such a continuum and critically examine the selection of appropriate values of effective porosity, a widely-used parameter for mass transport modelling in aquifers. Effective porosity is a transient phenomenon, related to the porosity continuum by the timescales under which mass transport occurs. An analysis of 55 tracer tests and 20 well inflow tests in English chalk aquifers identifies spatial scaling in groundwater velocity and groundwater flow respectively, which are interpreted within the context of the wider literature on carbonate aquifers globally. We advance transport modelling in the Chalk by developing a fissure aperture velocity mapping method using transmissivity data from existing regional groundwater models, together with the identified transient and spatial scaling phenomena. The results show that chalk aquifers exhibit widespread rapid groundwater flow which may transport contaminants rapidly in almost any setting.Supplementary material at https://doi.org/10.6084/m9.figshare.c.5403807
