“…FOF, unless it induces excessive activity avoidance, may indeed be helpful, because it increases caution in daily activities [6]. Fear-induced activity avoidance, when present at an excessive level, may actually lead to a deconditioning effect on muscle strength and postural control, which may further contribute to needless restrictions in participation in physical and social activities, resulting in further muscle atrophy, lower mobility, and worse balance, increasing the risk of falling, social isolation, depression, and functional decline [7,10,11]. Thus, the main problem in FOF’s negative consequences seems to be fear-induced activity avoidance and the resulting physical weakness.…”
