“…On the other hand, other studies have observed increased body sway in patients with PD [5,[7][8][9][10]. It has been observed previously that, in the absence of visual cues, the line of gravity is shifted significantly backwards in patients with PD of Hoehn and Yahr (HY) Stages 3 and 4 [7]. The increased Page 5 of 27 A c c e p t e d M a n u s c r i p t 3 mediolateral postural sway in patients with PD of HY Stages 1 to 3 with eyes closed has been shown to be a useful clinical observation to identify postural instability and increased risk of falls [11].…”

“…In later stages of the disease, the CFP position at rest shifts forward, 68,69 possibly because patients now attempt to compensate for their tendency to fall backward. Of interest, when such patients are asked to close their eyes, the CFP again shifts backward, 70 suggesting that patients use visual feedback to actively keep the CFP away from the disease-related preferential fall direction. A stooped posture is indeed biomechanically effective in protecting against backward falls, 27 but the price paid may be an increased likelihood of forward falls.…”

Falls and freezing of gait in Parkinson's disease: A review of two interconnected, episodic phenomena

et al. 2004

Falls and freezing of gait are two "episodic" phenomena that are common in Parkinson's disease. Both symptoms are often incapacitating for affected patients, as the associated physical and psychosocial consequences have a great impact on the patients' quality of life, and survival is diminished. Furthermore, the resultant loss of independence and the treatment costs of injuries add substantially to the health care expenditures associated with Parkinson's disease. In this clinically oriented review, we summarise recent insights into falls and freezing of gait and highlight their similarities, differences, and links. Topics covered include the clinical presentation, recent ideas about the underlying pathophysiology, and the possibilities for treatment. A review of the literature and the current state-of-the-art suggests that clinicians should not feel deterred by the complex nature of falls and freezing of gait; a careful clinical approach may lead to an individually tailored treatment, which can offer at least partial relief for many affected patients.

“…Individuals with PD have a reduced ability to correctly process and the use of feedback signals from proprioreceptors, which may be the result of the basal ganglia dysfunction in the brain, which are place of integration of sensory information from a variety of receptors, and produce a plan of the intended motion. These disorders are likely to be compensated by the sight [28,29]. Good visual function is also important in the rehabilitation of patients with PD.…”
