Measuring progress to healing: A challenge and an opportunity.

Complete healing is problematic as an endpoint for evaluating interventions for wound healing. The great heterogeneity of wounds makes it difficult to match groups, and this is only possible with multivariate stratification and/or very large numbers of subjects. The substantial time taken for wounds to heal necessitates a very lengthy study.

Remote monitoring of sitting behavior of people with spinal cord injury.

The clinical assessment of risk factors leading to pressure sores is normally undertaken in a hospital clinic. However, knowledge of the sitting behavior of the patient outside the clinic may more realistically and comprehensively identify these factors. Many patients, for example, are thought to sit habitually with more pressure on one buttock than the other, and this may significantly increase the risk.
