is a physical fitness system developed in the early 20th century by Joseph Pilates, after whom it was named. Pilates called his method “Contrology”. It is practiced worldwide, especially in Western countries such as Canada, the United States and the United Kingdom. As of 2005, there were 11 million people practicing the discipline regularly and 14,000 instructors in the United States.
There is only limited evidence to support the use of Pilates to alleviate low back pain, or improve balance in elderly people. Evidence from studies show that while Pilates improves balance, limited data exists on whether this impacts on falls by the elderly. Pilates has not been shown to be an effective treatment for any medical condition. There is some evidence regular Pilates sessions can help muscle conditioning in healthy adults, when compared to doing no exercise.
