Since that initial system was created, other handheld commercial systems are being developed, such as Skulpt, for use in both neuromuscular disease assessment and for fitness monitoring, including the calculation of a muscle quality (or MQ) value. This latter value aims to provide an approximate assessment of the relative force-generating capacity of muscle for a given cross-sectional area of tissue. Muscle quality, for example, is a measure used in the assessment of sarcopenia.
