“…Grip strength has been widely and routinely evaluated for decades in rheumatology as a functional measure in patients with joint inflammation, osteoarthritis or other musculoskeletal diseases (e.g. Bijlsma et al, 1987;Pincus and Callahan, 1992;Spacek et al, 2004;Lee et al, 2013a;Donato et al, 2018;Beaudart et al, 2019), and remarkably, it has long been known to correlate with pain (Callahan et al, 1987;Fraser et al, 1999;Overend et al, 1999;Lee et al, 2013b;LoRusso et al, 2018). Grip strength assessment in experimental animals, however, was developed for a very different purpose: to assess the effects of muscle relaxants and to test drug-induced toxicity (Tilson, 1990;Nevins et al, 1993).…”
