In making this consensus recommendation, the work group is issuing a recommendation consistent with current practice. However, the work group also acknowledges the paucity of evidence on the effectiveness of physical therapy, including its effects on either the duration or severity of these impairments (none of the eight studies included in this guideline that reported that their patients received post-operative physical therapy.42, 44-46, 51, 52, 56, 57 evaluated the effects of that therapy), or whether supervised therapy and unsupervised therapy yield different outcomes. Accordingly, it is not possible to determine whether patients should be offered supervised or unsupervised therapy.
The work group also notes that there are minimal risks associated with physical therapy, which, given its potential benefits, also argues for offering it to patients. These patients should be offered sufficient information to allow them to choose between supervised and unsupervised therapy, given their own, unique circumstances.
