Post-TKA Recovery Time Claims: Statement about getting TKA patients "walking 2 weeks sooner" aligns with the evidence. For instance, early aquatic physical therapy after orthopedic surgery improves functional outcomes without increasing wound complications.
- A 12-week progressive aquatic resistance training program increased habitual walking speed by 9% and decreased stair ascending time by 15% in patients 4-18 months post-knee replacement.
- The American Physical Therapy Association guidelines note that aquatic exercise following TKA shows positive effects on walking distance, balance, and physical function.
- Neurological Gait Training: The claim about safe gait retraining is well-supported. Aquatic therapy demonstrates statistically significant improvements over land therapy for functional reach (3.5 points better), gait speed (0.049 m/s faster), and Berg Balance Scale (2.3 points higher) in stroke rehabilitation.
- Multiple systematic reviews confirm "fair" evidence that aquatic therapy improves dynamic balance and gait speed in neurological conditions.[5-6]
Fall Risk Reduction: Your claim about cutting fall risk "in half" needs more specificity. While hydrotherapy shows moderate-quality evidence for improving balance function in Parkinson's disease patients, and reduces falls in some studies (one trial showed a reduction of 2.4 falls vs. 0.4 in controls), the 50% reduction claim requires supporting data from your specific program.
[7-9]
Cardiac Rehabilitation: The assertion about movement "without overloading the heart" is physiologically accurate. Aquatic exercise in cardiac rehabilitation patients produces similar improvements in exercise capacity and vascular function as land-based programs. [10-12] Water immersion creates favorable hemodynamic conditions without increasing myocardial oxygen requirements excessively. [13-14]
Pain Reduction: Well-supported. Aquatic therapy produces moderate improvements in pain compared to no exercise (SMD -0.31) in musculoskeletal conditions. [15] For knee osteoarthritis specifically, aquatic exercise significantly reduces pain (SMD -0.58) and improves physical function. [16-17] Low back pain patients also found relief with aquatic therapy equaling or exceeding land-based treatment [18].
