Sonora Cryo — Ultrasound + Cryotherapy (SNR005)

The Sonora Cryo combines therapeutic ultrasound with cryotherapy delivery in a clinically powerful synergistic system. Cold ultrasound therapy is highly effective for the treatment of inflammatory and painful states — the anti-inflammatory action of ultrasound is amplified by the analgesic, anti-edema, and pain-relieving action of cryotherapy, generating thermal, mechanical, cavitation, biological, and phonophoresis effects simultaneously. Used as an anti-inflammatory, analgesic, anti-swelling agent, and to combat muscle contractures, Sonora Cryo is the most differentiated and clinically potent variant in the Sonora range.

Sonora Cryo — The Clinical Science of Cold Ultrasound Therapy

The Sonora Cryo's synergistic combination of cryotherapy and ultrasound produces a clinically compelling multi-mechanism treatment response that exceeds what either modality achieves independently:

Ultrasound Contribution:

• Mechanical cavitation effects — stable and transient acoustic cavitation producing micro-streaming and membrane permeability enhancement
• Anti-inflammatory prostaglandin synthesis inhibition
• Fibroblast stimulation and collagen synthesis acceleration
• Mast cell degranulation and histamine release modification

Cryotherapy Contribution:

• Analgesic effect via slowing of nociceptive nerve conduction velocity
• Anti-edema effect via vasoconstriction and reduced capillary permeability
• Anti-inflammatory effect via metabolic rate reduction and enzyme activity suppression
• Muscle spasm reduction via gamma fibre activity inhibition

Combined Synergistic Effect: The cryotherapy component reduces tissue temperature and metabolic demand, preventing the unwanted thermal accumulation that can limit therapeutic ultrasound intensity in sensitive acute conditions — enabling higher effective acoustic intensity delivery in acutely inflamed tissue than would be tolerated with standard warm-contact ultrasound. Meanwhile, ultrasound's cavitation and micro-streaming effects enhance the penetration of the cryo effect into deeper tissue layers beyond the superficial cooling typical of surface cryotherapy application alone.
