Another important aspect to consider when promoting T’ai Chi (and those comparable) exercise programs, is their cost-effectiveness, particularly at the population level.
We conducted an epidemiological cost modelling of population-wide T’ai Chi delivery for community dwelling older people in Australia (Day et al, Injury Prevention, 2010 16: 321-326).
Whilst we agree that there are likely to be many individual and other benefits to T’ai Chi, we also concluded that “Substantial investment in, and high population uptake of, T’ai-chi would be required to have a large effect on falls and fall-related hospitalisation rates.” Some specific delivery and uptake factors that could be addressed to ensure that T’ai Chi programs could provide good value for limited falls prevention resources are:
1. Reducing the program cost delivery per participant
2. Ensuring higher population uptake than was able to be modelled in the 4 T’ai Chi programs reviewed in our paper.
