“…Other structural factors (i.e., chest tightness and lymphedema; Baran et al, 2021; Haddad et al, 2013; Lee et al, 2019; Levy et al, 2012), psychological factors (i.e., pain catastrophizing, negative affect; Akbas et al, 2021; Boquiren et al, 2016), and functional factors (i.e., the presence of subacromial pain; Galiano‐Castillo et al, 2011; Lang et al, 2019, 2022; Lang, Kim, et al, 2020; Lang, Milosavljevic, et al, 2020; Prieto‐Gómez et al, 2020; Rasmussen et al, 2021; Shamley et al, 2009) are currently only cross‐sectionally related to motor behavioral outcomes, without further assessment of moderating mechanisms explaining their relationship. Since only prospective research can clarify the role of these factors on the development of altered motor behavior, there is a clear gap in current knowledge around their effective contribution to upper limb motor behavior.…”
