Skulpt is a fitness tracking company focused on muscle health. They raised finance on crowd funding platform Indiegogo. The company produce portable consumer electronic devices that measure body fat percentage and muscle quality. These devices rely on the use of electrical impedance myography (EIM) to measure muscle quality. EIM has been used to evaluate patients with neuromuscular diseases however the company is focused on marketing their products for the personal fitness market. The devices are handheld and are pressed against the skin area corresponding to a specific muscle group, an electrical current flows, impedance is measured and the output is a muscle quality score. Whereas the accuracy and validation of the device and approach has been questioned, particularly in healthy individuals, considerable data has been previously obtained showing EIM's sensitivity to muscle status in healthy individuals with aging and with muscle disuse. More recent work has also shown that the technique is sensitive to drugs that enhance muscle fiber hypertrophy.
