Pain-Reducing Effects of Physical Therapist-Delivered Interventions: A Systematic Review of Randomized Trials Among Older Adults With Dementia.

Only three randomized trials were found, limiting the certainty of the conclusions. All participants lived in nursing or residential care, so results may not apply to people with dementia living in the community. No studies tested active physical therapy interventions such as therapeutic exercise or functional training. None of the trials blinded participants or therapists, which can bias pain reporting. Studies did not account for the type of pain (e.g., nociceptive vs neuropathic), which may affect treatment response.

The paper notes support from the National Institutes of Health (Extramural) in the publication types, but the article text does not detail specific author conflicts or funding roles in the study design or writing.

Do not interpret the one positive finding for massage as general evidence that physical therapy reduces pain in dementia. The effect was inconsistent across trials, and massage did not help when added to routine care. The lack of evidence for active interventions means physical therapists should not stop using exercise for other benefits, but should be cautious about claiming pain reduction from passive modalities alone.
