Cold Water Immersion · Ice Baths & Plunge Tubs
Real recovery and mood signals, but skip the ice bath right after lifting if muscle is your goal.
Thermal recovery practiceNot an FDA-regulated medical treatment. Cold plunge tubs and chillers are sold as general wellness or recreational products, not cleared devices, and carry no approved disease claims.
Hyperbaric Oxygen · Pressurized O2 Therapy
Pressurized oxygen with ~14 solid medical uses; the home soft-chamber wellness boom rests on far thinner evidence
Pressurized oxygen therapyFDA clears HBOT chambers as Class II devices via 510(k). UHMS lists ~14 to 17 approved indications (decompression sickness, CO poisoning, gas gangrene, radiation injury, diabetic foot ulcers, sudden hearing loss). Anti-aging, autism, long-COVID and sports recovery are off-label; FDA has warned that unproven uses can delay real care.
TENS · Electrical Pain-Gating Therapy
Skin-surface electrical stimulation that aims to dampen pain signaling; mechanism is well grounded, clinical results vary
Electroanalgesia deviceFDA Class II under 21 CFR 882.5890; cleared via 510(k). Available both over-the-counter (general and arthritis pain) and by prescription. New units clear on substantial equivalence, usually without fresh efficacy trials.
Pneumatic Compression · Recovery Boots
Air-pumped sleeves that squeeze the limbs in waves; modest help for soreness, weak evidence for real performance gains
Mechanical recovery deviceMedical IPC pumps hold FDA 510(k) clearance for lymphedema, venous ulcers and DVT prophylaxis; consumer athletic recovery boots use the same mechanism but their faster-recovery and performance marketing claims sit outside any cleared indication.
PEMF · Pulsed Magnetic Fields
Real clearances for stubborn fractures and spinal fusion; the glowing wellness mat is a different, weakly-supported product
Electromagnetic stimulationFDA cleared/approved ONLY for narrow uses: bone-growth stimulators for fracture nonunion (Class III PMA, 1979) and as a lumbar spinal-fusion adjunct; ActiPatch 510(k)-cleared 2017 for knee OA and plantar fasciitis. Consumer wellness mats (HealthyLine, Bemer) are at most FDA-listed, which is NOT clearance and certifies no efficacy.
