Typically, elderly patients with hip fractures may have long
recovery times. At one hospital, the average amount of time that
elderly patients with hip fractures would spend in the hospital
before they could be released to home care was 15 days. A new
physiotherapy program is developed and researchers want to see if
this new program gives recovery times that are different than the
typical average amount. A random sample of 12 patients was enrolled
in the new program and...
