Backed by Real Research — Not Hype
We'd rather show you what the science actually says than sell you a miracle. Here's the real research behind the three therapies inside RescueKnee and RescueAnkle.
Infrared Heat
Widely recommended
Applying heat to a stiff, sore joint is one of the most widely recommended home self-care steps used by physical therapists to relax muscles and improve blood flow before movement.

Vibration Massage
Up to 40% less perceived pain
Gentle, non-painful vibration is thought to work through the body's own “pain gate” pathways — giving the nervous system a competing signal that can turn down how intensely pain is felt.

Compression
Most consistent evidence of the three
Systematic reviews and a 2025 network meta-analysis found that soft compression sleeves and braces provide immediate, moderate improvements in pain and function by improving joint stability and proprioception.

The honest bottom line: no heat, vibration, or compression device — including ours — reverses arthritis, rebuilds cartilage, or cures joint pain permanently. What the research supports is temporary, meaningful relief from day-to-day stiffness and soreness.
