The elderly population is growing, and with it, the demand for healthcare services that cater to their unique needs. Physiotherapists have traditionally worked with older persons after an injury (e.g., a fall-related hip fracture) or event (e.g., a stroke). However, in order for our profession to make a substantial contribution to the healthy aging agenda, we must use our knowledge in movement and exercise prescription, as well as our counseling skills, to encourage our clients throughout the health continuum to be physically active in their daily lives. To summarize, we must incorporate physical activity promotion into our work with older people in order to prevent chronic illnesses that impair their functional capacity, quality of life, and well-being.
