Hypokinesia

Hypokinesia is a medical term that means 'reduced movement'. It refers to a decrease in the amplitude or range of voluntary movements. This symptom often occurs in neurological conditions such as Parkinson's disease.

Causes of hypokinesia

The main cause of hypokinesia is a deficiency of dopamine in the brain. Dopamine is a neurotransmitter that is essential for regulating movements. In Parkinson's disease, the dopamine-producing cells in the substantia nigra, a specific area in the brain, gradually die. This leads to a reduction in automatic movements.

It is important to distinguish hypokinesia from akinesia (the inability to start movements) and bradykinesia (slowed movements). Other conditions that affect the basal ganglia (brain areas involved in motor control) can also cause hypokinesia.

Consequences of hypokinesia

Hypokinesia manifests in different ways, including:

• Reduced facial expression: A less expressive face, also called a 'masked face'.
• Less arm swing while walking: The natural movement of the arms while walking decreases.
• Reduced blinking: Less frequent blinking of the eyes, which leads to dry eyes.
• Monotonous speech: A flat, little-varied voice.

These symptoms affect daily functioning and can lead to social withdrawal or misunderstandings in communication.

Treatment of hypokinesia

Treatment of hypokinesia focuses on increasing dopamine levels in the brain and improving motor functions. This can be achieved with medication prescribed by a neurologist.

In addition, it is beneficial to stay active and improve muscle strength and mobility under the guidance of a physical therapist. An occupational therapist teaches patients to use aids that make everyday activities easier. In the case of speech problems, speech therapy is available to improve communication.

In some cases, deep brain stimulation (DBS) offers a solution. This is a surgical procedure in which electrodes are placed in specific brain areas to reduce symptoms.

Tips for coping with hypokinesia

In addition to medical treatments, the following strategies can help:

• Regular physical activity: Activities such as walking, swimming, boxing, or tai chi promote freedom of movement.
• Use of aids: Adjustments in the home and the use of special assistive devices make daily tasks easier.
• Seek support: Participating in support groups or engaging professional help provides many patients with emotional and practical support.
