“…The highly satisfactory results of functional restoration have been shown to be temporally stable (Mayer et al, 1987), and can be generalized across different socioeconomic and medico-legal systems (Bendix et al, 1996;Corey, Koepfler, Etlin, & Day, 1996;Hildebrandt, Pfingsten, Saur, & Jansen, 1997;Jousset et al, 2004). Finally, it has been demonstrated that functional restoration, along with other interdisciplinary approaches to pain management, are more cost-effective than standard conservative treatment (Gatchel & Okifuji, 2006;Skouen, Grasdal, Haldorsen, & Ursin, 2002;Turk, 2002;Turk & Okifuji, 1997).…”
