Mathematical modeling of recovery curves

As the population of people in the globe continues to age, there will be a growing demand for health issues including treatment of Total Hip Arthroplasty (THA) and Total Knee Arthroplasty (TKA). This will result in a growth in post-operation rehabilitation services. In order to meet this growth, it will be beneficial for occupational therapists and physical therapists to have an understanding of a patient’s expected post-surgery recovery rate. Once developed these rates can be used to benchmark individual patient improvement, help estimate expected costs and lengths of therapy, and possibly help design optimal treatment session scheduling. In this paper, we consider Hierarchical Linear Model to analyze how male and female patients respond to TKA and similar surgeries.
