Lihasjäykkyys

Lihasjäykkyys, known in English as muscle stiffness or rigidity, refers to a sensation of tightness or resistance in the muscles. This condition can range from mild discomfort to severe immobility and can affect individuals of all ages. It is often experienced after periods of inactivity, such as waking up in the morning, or after strenuous physical exertion.

The causes of lihasjäykkyys are varied. In many cases, it is a normal physiological response. After exercise, microscopic tears in muscle fibers can lead to inflammation and stiffness, commonly known as delayed onset muscle soreness (DOMS). Prolonged sitting or lying down can also cause muscles to shorten and stiffen. Dehydration and electrolyte imbalances can also contribute to muscle cramps and stiffness.

Certain medical conditions can manifest with lihasjäykkyys as a symptom. Neurological disorders like Parkinson's disease and multiple sclerosis often present with spasticity, a form of muscle stiffness. Musculoskeletal conditions such as arthritis can also lead to joint and muscle stiffness. Even stress and anxiety can cause involuntary muscle tension, resulting in a feeling of rigidity.

Treatment and management of lihasjäykkyys depend on the underlying cause. For exercise-induced stiffness, rest, stretching, and hydration are often effective. Gentle massage and warm compresses can also provide relief. If lihasjäykkyys is persistent or severe, or accompanied by other symptoms like pain, swelling, or loss of function, it is advisable to consult a healthcare professional to rule out any underlying medical conditions and receive appropriate treatment.
