Special Issue Information

Dear Colleagues,

Personal sensor technologies, technologies worn on or in the body, provide opportunities to examine interactions between people and the environment in free-living conditions. Several technologies make use of smartphones or dedicated body-worn sensors to monitor health, physiology, and many other aspects of the human body, as well as exposures to environmental conditions. Increasingly small sensors, novel hardware developments, and open-source software provide opportunities to collect and integrate several types of data collected from personal sensors, at a relatively low cost, with unprecedented spatial, temporal, and contextual detail. Leveraging increasingly smaller and more powerful computing hardware, ubiquitous wireless networks, and IoT devices, and integrating existing sensor technologies affords opportunities to expand our understanding of how human health and behaviours are shaped by the environment. New data sources from these personal sensors with varying degrees of precision, accuracy, and quality require advances in data science and data fusion. Big data created by these devices necessitates the development of innovative, integrated theoretical and statistical models to support the characterization of people–environment interactions and to derive useful evidence for policy and decision making. As well, given the spatial, temporal and contextual detail of the data personal sensors can collect, researchers must pay particular attention to ethical issues arising now and in the future with a view to understanding and limiting ethical challenges.

For this issue, we invite manuscripts, either original or review articles, on the theme of people–environment interactions. Submissions may choose to focus but are not limited to on one or more of the following areas:

  • Sensor development and integration;
  • Sensor validation and comparison;
  • Sensor data integration, sensor data scaling, fusion and modelling;
  • Sensor applications, particularly in health;
  • Ethical issues associated with the collection and analysis of personal sensor data.

This Special Issue aims to advance our understanding of how sensor technologies are employed in the study of people–environment interactions with the aim to support human health.

Automated wireless sensing of force dynamics during a visuomotor control task was used to rapidly assess residual motor function during finger pinch (right and left hand) and lower lip compression in a cohort of seven adult males with chronic, unilateral middle cerebral artery (MCA) stroke with infarct confirmed by anatomic magnetic resonance imaging (MRI). A matched cohort of 25 neurotypical adult males served as controls. Dependent variables were extracted from digitized records of ‘ramp-and-hold’ isometric contractions to target levels (0.25, 0.5, 1, and 2 Newtons) presented in a randomized block design; and included force reaction time, peak force, and dF/dtmax associated with force recruitment, and end-point accuracy and variability metrics during the contraction hold-phase (mean, SD, criterion percentage ‘on-target’). Maximum voluntary contraction force (MVCF) was also assessed to establish the force operating range. Results based on linear mixed modeling (LMM, adjusted for age and handedness) revealed significant patterns of dissolution in fine force regulation among MCA stroke participants, especially for the contralesional thumb-index finger followed by the ipsilesional digits, and the lower lip. For example, the contralesional thumb-index finger manifest increased reaction time, and greater overshoot in peak force during recruitment compared to controls. Impaired force regulation among MCA stroke participants during the contraction hold-phase was associated with significant increases in force SD, and dramatic reduction in the ability to regulate force output within prescribed target force window (±5% of target). Impaired force regulation during contraction hold-phase was greatest in the contralesional hand muscle group, followed by significant dissolution in ipsilateral digits, with smaller effects found for lower lip. These changes in fine force dynamics were accompanied by large reductions in the MVCF with the LMM marginal means for contralesional and ipsilesional pinch forces at just 34.77% (15.93 N vs. 45.82 N) and 66.45% (27.23 N vs. 40.98 N) of control performance, respectively. Biomechanical measures of fine force and MVCF performance in adult stroke survivors provide valuable information on the profile of residual motor function which can help inform clinical treatment strategies and quantitatively monitor the efficacy of rehabilitation or neuroprotection strategies.
