Key Takeaway
Contrast bath therapy combined with physical therapy improves pain, stiffness, and function in knee osteoarthritis patients.
Summary
This narrative review examined the role of contrast bath therapy as an adjunct treatment for knee osteoarthritis (OA). The authors reviewed the available literature on how contrast bath therapy, combined with physical therapy, affects pain, stiffness, and functional outcomes in OA patients.
The review found that contrast bath therapy provides analgesic and anti-inflammatory effects through its vascular pumping mechanism. Alternating vasodilation and vasoconstriction helps reduce joint swelling, improve local circulation, and decrease pain perception. When combined with structured physical therapy exercises, contrast baths appeared to enhance overall treatment outcomes.
The authors noted that contrast bath therapy is particularly appealing for OA management because it is non-invasive, low-cost, and can be performed at home. The review supports its integration into multimodal rehabilitation programs for knee OA, though more high-quality randomized trials are needed to establish optimal treatment parameters.
