Profile: Healthcare Fitness Products specializes in providing hand dynamometers, cryotherapy machines, treatment tables, chest dynamometers, ultrasound therapy products, heart rate monitors, and braces. We offer products for hospitals, physical therapy clinics, and chiropractors. Hand dynamometers are used for hand grip strength tests to give physical therapists, occupational therapists and other medical professionals quantitative assesment that can then be used to track rehabilitation progress. Grip strength tests can be used in cases of nerve injury, carpal tunnel syndrome, hand tendon injuries, and neormuscular disorders. In addition to medical clinics, grip strength tests are used in sports medicine and ergonomics. Hydraulic hand dynamometers use hydraulic technology to measure hand-grip strength for individuals who have hand trauma or dysfunction. Pneumatic hand dynamometers use air pressure to measure grip strength. This air pressure measurement technology is used in squeeze bulb dynamometers, which have many benefits. They cost less than other dynamometers. They are small and easy to use, measurements are based on air pressure and calibration is in Pounds Per Square Inch (PSI), maximum measurements on the analog dial remain in place until unit is reset.
