Postural deformities in Parkinson's disease

In-Home Posture Evaluation and Visual Feedback Training to Improve Posture with a Kinect-Based System in Parkinson’s Disease

“…Posture is often affected in individuals with Parkinson's disease (PD) [1]. Abnormal postures include anterior trunk bending, lateral trunk bending, and neck flexion.…”

“…Abnormal postures include anterior trunk bending, lateral trunk bending, and neck flexion. Mechanisms underlying the development of the postural abnormalities in PD are not well understood, but a number of possible mechanisms, such as dystonia, rigidity, drugs, myopathy, skeletal and soft tissue changes, and proprioceptive disintegration have been proposed [1]. There is insufficient evidence to support the effectiveness of the adjustment of antiparkinson medications [2,3], deep brain stimulation [4][5][6], botulinum toxin or Lidocaine injections [7,8], and orthosis and physiotherapy [9][10][11][12].…”

“…Misperception of the vertical position due to disintegration of proprioceptive, somatosensory and vestibular information has been suggested to be associated with the postural abnormalities such as anterior bending posture and lateral bending posture in individuals with PD [1]. A misperception of the vertical position might thus contribute to the difficulty that some PD patients with postural abnormalities have in making their posture erect.…”

Alterações Posturais na Doença de Parkinson

“…Casos de maior comprometimento clínico, representados pela síndrome da cabeça caída (dropped head), pela camptocormia e pela síndrome de Pisa, são exemplos de posturas anormais graves que podem acometer os pacientes portadores da DP. A prevalência destes sintomas na DP varia de 3 a 18%, de acordo com os estudos realizados 1,2 .…”

“…Pode resultar da fraqueza da musculatura extensora do pescoço ou do aumento do tônus da musculatura flexora. Ocorre raramente na DP, sendo mais frequentemente observada na atrofia de múltiplos sistemas 1 .…”
