The goal of this project was to investigate the clinical effectiveness of temperature-controlled prosthesis liners over the long-term. To that end, outcome data were collected at two sites over a total period of 12 months, including two 6-month intervention periods with comparable climate conditions i.e., equal amounts of cold and warm weather. Results suggest that use of temperature-controlled liners did help reduce days of non-prosthesis use by an average of more than two days per year, a 12 percent improvement. Self-reported ambulation and health outcomes saw increases of 5.5 and 4 percent respectively. However, the findings are not considered conclusive since the study had unexpected sample size limitations so that these differences did not rise to the level of statistical significance. Both participant recruitment and retention were challenged by unforeseen factors, most notably the Covid-19 pandemic in the last year of the study period. The study protocol as well as preliminary results have been disseminated in various conference abstracts and as journal manuscripts.
