Abstract
The invention belongs to the field of improvement of Parkinson patients, and particularly relates to a carpet for relieving a Parkinson patient from improving a frozen gait, which is possible to improve FOG attacks of partial patients aiming at the existing dopaminergic therapy, but is not effective for the patients who take FOG during the medicine taking period. The DBS has unsatisfactory effectiveness in the FOG, is ineffective for the FOG in the 'open period', has contraindications and risks in operation and has higher cost.
Description
Technical Field
The invention relates to the technical field of improvement of Parkinson patients, in particular to a carpet for relieving the Parkinson patients and improving frozen gait.
Background
Freezing of the gait in Parkinson's Disease (PD) patients is a common and disabling condition characterized by sudden and short attacks that do not produce an effective ante-step and cannot walk as if the feet were stuck to the ground. As a paroxysmal phenomenon, gait freeze attacks can occur in public or dangerous situations and have a large impact on the sense of safety and independence. This may result in the patient feeling alone and feeling the burden of being a caregiver or family. Furthermore, FOG increases the risk of falls, leading to an increased risk of fractures, and after 20 years of disease progression, the prevalence of FOG affects 81% of patients, a significant management challenge.
At present, there is no effective drug for treating FOG in PD. Although FOG is commonly observed in "pill break" conditions, a significant proportion of patients still experience FOG episodes during "pill break". Thus, dopaminergic therapy may improve the onset of FOG in some patients, but is not effective in those patients who develop FOG during their dosing. DBS is not satisfactorily effective in FOG, and although bilateral subthalamic DBS can improve "off-stage" FOG, it is not effective for "on-stage" FOG, and there are contraindications and risks associated with surgery, and higher costs, so we propose a carpet for alleviating parkinson's disease patients to improve frozen gait to solve the above mentioned problems.
