New Measure of Hand Strength Can Assess Disease Severity, Patient Fitness
A new device that measures handgrip strength in people with fibromyalgia has the potential to overcome some of the limitations of current hand-held dynamometers, researchers in Italy that developed the device reported. The cylindrical-shape tool also confirmed weaker handgrip strength in these patients, directly correlating it with disease severity. The study, “Force-time curve features of handgrip strength in fibromyalgia syndrome,” was published in the journal Scientific Reports.   Fibromyalgia patients often see their physical fitness lessen at their disease progresses, including a loss in muscle strength, balance, and flexibility. Previous studies have reported that women with fibromyalgia have 20% to 36% less strength compared to healthy women. Handgrip strength is defined as the maximum amount of force a person can generate with each hand. In addition to assessing the status of a patient's hand, this parameter can be used as a measure of overall muscle strength, which is related to physical fitness.    "In healthy subjects, HGs [handgrip strength] is correlated to knee extension strength and can therefore be a s
