Dysynergy (Dyssynergid), Asynergia (Asynergia)

Dyssynergid, Asynergia - impaired coordination of movements, manifested mainly in the performance of awkward, clumsy movements by patients with cerebellar lesions. These include:

1. Dysmetria - the implementation of movements without proportionality to their strength. When performing purposeful movements, patients either bring the limb short of the target or throw it over.

2. Intention tremor is a tremor that occurs when performing purposeful movements. As you approach the target, the amplitude of the tremor increases.

3. Dysdiadochokinesis is a violation of the ability to quickly and smoothly perform alternating movements, for example, pronation and supination of the hands. Movements become intermittent, sweeping, and irregular.

4. Unsteady shaky gait. The gait becomes scattering, shuffling, and uneven. Patients experience difficulty turning and stopping.

Thus, dyssynergia and asynergia are manifested by a complex of symptoms associated with impaired coordination and accuracy of movements when the cerebellum is damaged.

Dyssynergid and Asynergia are two neurological conditions associated with impaired motor coordination. These conditions are often observed in patients with cerebellar lesions, resulting in awkward and clumsy movements.

One of the main symptoms of dyssynergia is dysmetria. Dysmetria manifests itself in the performance of movements without proportioning their strength. For example, a patient with dyssynergia may make a movement too strong or too weak without controlling the amplitude or force of the movement. This may result in the patient being unable to perform precise and purposeful movements, such as hitting a target or manipulating objects.

Intention tremor is another characteristic symptom of dyssynergia. This type of tremor occurs when the patient attempts to perform a purposeful movement, for example, when trying to bring the hand to a certain point or trying to perform precision movements with the fingers. Instead of smooth and steady movement, the patient may experience tremors and an inability to maintain position accurately.

Dysdiadochokinesis is another symptom of dyssynergia, which is characterized by impaired ability to quickly change the direction of movements. Patients with dysdiadochokinesis may have difficulty performing consistent and rapid movements, such as swinging their arms or moving their legs. This leads to clumsiness and inconsistency in the execution of movements.

Unsteady, unsteady gait may also be associated with dyssynergia and asynergia. Patients with these conditions often have difficulty maintaining balance and coordination when walking. Their gait may be unsteady, wobbly, and ineffective. This can lead to an increased risk of falls and injuries.

Treatment of dyssynergia and asynergia is aimed at improving motor coordination and reducing symptoms. Physical therapy and rehabilitation can be helpful treatments as they help improve muscle control and strength. Other treatments may include medications to improve motor function and reduce shaking.

Dyssynergid and asynergia are conditions that significantly affect the quality of life of patients with cerebellar lesions. Understanding these conditions and developing effective treatments are important challenges for neuroscientists and rehabilitation specialists. Thanks to modern diagnostic methods and an integrated approach to treatment, patients with dyssynergia and asynergia can achieve significant improvements in their coordination of movements and increase their vital activity.

Dysynergies (Dysynergias) are a violation of voluntary movement due to the lack of simultaneous contraction of muscles acting in different directions or when the functional connection between them is disrupted. This is a group of different neurological disorders characterized by clumsiness and the inability to make precise and smooth movements. The most common among these diseases are asynergies and dissociative deviations.

Asynergia is the cessation or weakening of the selective activation of one or more muscle proprioceptors (receptors for the position and direction of movement in joints and muscles) necessary to perform precise movements with a constant inertial effect. Depending on the location of the damage to the cortical and subcortical structures, frontal, occipital (pyramidal), cerebellar (cerebellopontine), vascular and other localizations of asynergies are distinguished. Hypothalamic and specific malignant tumors can also cause asynergism.

The essence of the disorder is in the production of instinctive movements in the absence
