Overview
Fluidotherapy is a modality involving placing the upper extremity in a machine that contains cellulose particles (similar to grounded up dried corn husks)
When the machine is turned on, the cellulose particles are heated up (typically 115-120°F) from hot air and blown around, creating essentially a dry fluid effect
The temperature and speed of cellulose particles can be adjusted
The cellulose particles blowing around provides tactile sensory stimulation, making fluidotherapy beneficial to be used as a method for desensitization
The upper extremity is in an open space in the machine, allowing AROM, coordination, or manipulation exercises to be performed at the same time
Can help improve:
Pain
Edema
Inflammation
Stiffness
Hypersensitivity
Wound healing (if wound is closed)
Increases tissue extensibility
Warms the tissues and makes them more pliable for PROM
Typical treatment time is 10 minutes
Science of Heat
Heat causes vasodilation, increased cellular metabolism, and beginning of phagocytosis
The heat from fluidotherapy widens blood vessels and boosts cell activity, helping nutrients and oxygen reach tissues more efficiently
The immune system starts clearing out damaged cells and waste, supporting tissue healing and inflammation control
Indications
Pain
Joint stiffness/decreased range of motion
Hypersensitivity
Scar remodeling
Peripheral nerve injuries
Muscle spasms
Contraindications
Open wound(s)
Infections
Heat sensitivity
Impaired sensation (such as from neuropathy)
Impaired circulation (such as from peripheral vascular disease)
Malignancy (if there is cancer in the treatment area)
