Which are the symptoms of Primary Orthostatic Tremor?

Symptoms of Primary Orthostatic Tremor

Primary Orthostatic Tremor (POT) is a rare neurological disorder characterized by a rapid tremor that occurs in the legs and trunk when standing upright. This condition is often misdiagnosed or overlooked due to its unique symptoms and the lack of awareness among healthcare professionals.

Tremor: The hallmark symptom of Primary Orthostatic Tremor is a high-frequency tremor that typically affects the legs, although it can also involve the trunk and arms. The tremor is usually described as a feeling of vibration or shaking, occurring at a frequency of 13-18 Hz. It is most pronounced when standing still and diminishes or disappears when sitting down or walking. The tremor can be so severe that it causes unsteadiness and difficulty maintaining balance.

Leg Stiffness: People with Primary Orthostatic Tremor often experience a sensation of leg stiffness or tension, which can contribute to the difficulty in standing for prolonged periods. This stiffness is not related to muscle weakness but rather a result of the tremor activity.

Unsteadiness and Balance Problems: Due to the constant tremor in the legs, individuals with Primary Orthostatic Tremor may have significant difficulties with balance and coordination. They may feel unsteady or wobbly when standing, making it challenging to perform daily activities that require standing or walking for extended periods.

Anxiety and Fear of Falling: The chronic nature of Primary Orthostatic Tremor can lead to increased anxiety and fear of falling. The constant tremor and associated balance problems can significantly impact a person's quality of life, leading to social isolation and reduced participation in activities.

Relief with Walking or Sitting: One distinguishing feature of Primary Orthostatic Tremor is the relief experienced when walking or sitting down. The tremor typically diminishes or completely disappears during movement, providing temporary relief to individuals with this condition. However, the symptoms often return shortly after stopping the movement.

Difficulty with Activities of Daily Living: Primary Orthostatic Tremor can significantly impact a person's ability to perform activities of daily living. Standing in line, cooking, showering, or even brushing teeth can become challenging tasks due to the constant tremor and associated balance problems.

Progressive Nature: Primary Orthostatic Tremor is considered a progressive disorder, meaning that the symptoms tend to worsen over time. Initially, the tremor may be mild and only noticeable when standing still, but it can gradually intensify and affect other body parts, leading to increased disability.

Impact on Sleep: Many individuals with Primary Orthostatic Tremor report difficulties with sleep due to the constant tremor. The tremor can persist even during sleep, causing restless nights and daytime fatigue.

Misdiagnosis: Primary Orthostatic Tremor is often misdiagnosed or mistaken for other movement disorders, such as Parkinson's disease or essential tremor. This misdiagnosis can delay appropriate treatment and management strategies.

Lack of Awareness: Primary Orthostatic Tremor is a relatively rare condition, and there is a lack of awareness among healthcare professionals. This lack of awareness can contribute to the underdiagnosis and undertreatment of individuals with this disorder.

If you or someone you know is experiencing symptoms consistent with Primary Orthostatic Tremor, it is essential to consult with a healthcare professional who specializes in movement disorders. Early diagnosis and appropriate management can help improve quality of life and minimize the impact of this condition.
