Proprioceptive Deficits in Degenerative Cervical Myelopathy

Официальное название

Early Detection of Proprioceptive Dysfunction in Degenerative Cervical Myelopathy by Proprioceptive Functional Analysis in Activities of Daily Living

Обзор

Proprioceptive deficits in degenerative cervical myelopathy (DCM) is a progressive neurological deficits in somatosensory and motor function which affects the body balance and motor control. DCM usually presents with body incoordination, hand clumsiness and gait disturbance associated with proprioceptive dysfunction that hinders the physical performance and functions. In this study, a non-invasive assessment protocol on proprioception will be developed for detecting subtle proprioceptive deficits at the early stage of disease through simple Physical Performance Tests for population older than 45. By adopting the physical performance tests as the diagnostic predictors of DCM, we aim to avoid the development of devastating consequences and disabilities.

Подробное описание

DCM is a chronic insidious disease, one of the most disabling orthopaedic conditions, which involves compression of the spinal cord by the surrounding structures in cervical spinal region. It characterizes with progressive neurological deficits in body coordination, hand clumsiness and gait disturbance as the preliminary symptom which may cause by proprioceptive dysfunction .

Physical performance and function hinder patients' hand clumsiness, gait disturbance and body imbalance. The incoordination between body, upper limbs and lower limbs will be resulted from proprioceptive deficits caused by spinal cord compression. By adopting the Proprioceptive Functional Analysis System (PFAS), proprioceptive deficits over the core body joints and peripheral joints could be tested during Activity of Daily Living (ADL) with reference to normal subjects' performance. All subjects will be tested by the PFAS and Physical Performance Tests.

The idea of regional proprioceptive deficit will be incorporated in the assessment protocol for DCM to facilitates a breakthrough from the traditional DCM functional evaluation.

In developing a non-invasive assessment protocol to assess proprioceptive deficit, we aim to detect subtle proprioceptive deficit from the tests, especially at the very early stage of disease. We target to demonstrate the validity of Physical Performance Tests are evenly high as that of the advanced technology, PFAS.

Consequently, by adopting the valid Physical Performance Tests in health screening scheme for population older than 45 within the community can serve as an early diagnostic parameter of DCM and avoid delayed treatment leading to devastating consequences and disabilities.
