概括
阿舍尔综合征 (USH) 患者表现出平衡障碍,特别是在不稳定的表面上,更多地依赖于自身感知而不是视力. 活动特定平衡信心 (ABC) 尺度将USH患者与对照患者区分开来,而不是亚型.
科学领域:
- 神经学 神经学
- 眼科医生 眼科 眼科
- 听力学 听力学是指听力学.
背景情况:
- 阿舍氏综合征 (USH) 是遗传性聋盲的主要原因.
- 了解USH中的平衡控制对于管理功能赤字至关重要.
研究的目的:
- 为了研究USH患者的姿势控制,使用姿势图.
- 阐明聋盲个体的感官补偿策略.
- 为了将特定活动的余额信心 (ABC) 尺度与余额参数相关联.
主要方法:
- 压力中心 (CoP) 的时间性泌尿后分析 (古典和波形) .
- 研究包括34名USH患者 (USH1,USH2,USH4) 和35名对照.
- 使用静态/动态平台,可变视觉条件和ABC尺度评估平衡.
主要成果:
- 与对照组相比,USH患者在不稳定的表面上显著增加了姿势摇摆和角度速度.
- 视力障碍是影响姿势缺陷的主要因素;前体和体感系统没有显著差异.
- USH患者的视觉依赖性减少,这表明他们依赖其他感官输入来保持平衡.
结论:
- USH患者,特别是USH1患者,平衡控制较差,特别是在不稳定的表面上开眼睛时.
- 患者似乎抑制视觉输入,更多地依赖自身感知.
- USH2患者可能会采用不同的多感官平衡策略,这些策略在ABC尺度上没有完全捕捉到.

Disorders of the Urinary System
275
The urinary system is responsible for eliminating waste and excess fluids from the body. However, disorders of the urinary system can arise due to various reasons like infections, stress, age, congenital abnormalities, and lifestyle.
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...

Imbalances in Cardiac Output
1.4K
The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send...

Disorders of the Autonomic Nervous System
594
The autonomic nervous system (ANS) is an intricate network of nerves that controls functions such as the regulation of heart rate, digestion, and blood pressure regulation. When this system malfunctions, it can lead to various disorders that affect multiple bodily functions. One common feature of many autonomic disorders is the involvement of smooth blood vessels, which play a crucial role in regulating blood flow throughout the body.

Disorders of Acid-Base Balance
171
The human body maintains a precise pH range of arterial blood between 7.35 and 7.45. Deviations result in either acidosis (pH < 7.35) or alkalosis (pH > 7.45). These conditions are further classified as respiratory or metabolic disorders based on their underlying cause.
Respiratory Acidosis and Alkalosis
Respiratory acidosis occurs due to an increase in the partial pressure of carbon dioxide PCO2 in the blood. It often arises from shallow breathing or impaired gas exchange caused by...

Homeostatic Imbalance
22.4K
Homeostasis is the maintenance of a stable internal environment within the body, which is crucial for the proper functioning of cells, tissues, organs, and organ systems. The body has various control mechanisms that work together to regulate various physiological parameters such as temperature, blood pressure, pH balance, and fluid balance, to name a few. These control mechanisms are based on feedback loops that can be either positive or negative.
However, sometimes these feedback loops fail,...
