Which conditions have demonstrated PT cost benefit?

• A. Asthma, dermatitis
• B. Acute heart failure
• C. Low back pain, knee OA, falls prevention, stress urinary incontinence, cancer rehab, and vascular claudication
• D. None

Answer: (C)

Understanding cost benefit in physical therapy means looking at both health outcomes and the total costs to the health system. When PT programs improve function or reduce symptoms while also lowering downstream healthcare spending, they are considered to have demonstrated cost benefit.

Several conditions have solid economic evidence showing this benefit. In chronic low back pain, targeted PT with structured exercise and manual therapy can cut the use of imaging, injections, and surgical referrals, leading to lower overall costs while patients regain function. For knee osteoarthritis, PT as a first-line approach can delay or avoid knee replacement and reduce related medical costs. Falls prevention programs delivered by PT reduce injuries, hospital admissions, and long-term care needs, producing cost savings. Pelvic floor PT for stress urinary incontinence often provides symptom relief without surgery, lowering treatment costs. Cancer rehabilitation helps patients recover function with fewer complications, which translates into lower healthcare utilization. Supervised exercise for vascular claudication improves walking and may reduce the need for invasive procedures, yielding cost benefits.

Evidence for asthma and dermatitis as PT cost beneficiaries is less consistent, and the breadth of cost-benefit findings for acute heart failure is not as strong as for the listed conditions. That combination of robust economic data across these particular conditions makes them the best-supported group for PT cost benefit.
