“…In clinical assessment instruments used to assess functional progress during wrist and forearm rehabilitation, forearm strength contributes up to 25% of the overall functional assessment (Souer, LozanoCalderon, & Ring, 2008). Thus, forearm pronation and supination strength are integral parts of the rehabilitation of people with elbow disorders, such as lateral epicondylitis (Alizadehkhaiyat et al, 2007;Erak, Day, & Wang, 2004;Kohia et al, 2008), rheumatoid arthritis (Shigeyama, Inoue, Hashizume, Nagashima, & Senda, 1997), forearm fractures (Dubberley, Faber, MacDermid, Patterson, & King, 2006;Droll et al, 2007;Souer et al, 2008), and nerve impairment (Rainville, Noto, Jouve, & Jenis, 2007;Rosén, Dahlin, & Lundborg, 2000) as well as the development of baseball (Szymanski, Szymanski, Molloy, & Pascoe, 2004) and tennis athletes (Alizadehkhaiyat et al, 2007;Ellenbecker, Roetert, & Riewald, 2006).…”
