Motor Impairment in CRPS and Reflex Sympathetic Dystrophy
Motor impairment is a common occurrence in individuals suffering from CRPS (Complex Regional Pain Syndrome) and reflex sympathetic dystrophy. The most prevalent motor impairments associated with these conditions include general weakness and a decrease in range of motion. However, the impact of these conditions on the limbs can extend beyond these symptoms, leading to a loss of grip strength. In some cases, individuals with CRPS may even develop dystonia, characterized by involuntary muscle contractions and spasms.
Causes
The exact causes of CRPS (Complex Regional Pain Syndrome) or reflex sympathetic dystrophy are still unknown to doctors. However, it has been observed that the latter type often develops in individuals who have a history of immobilization, and this state tends to worsen the existing symptoms. In addition, the development of color and temperature changes, as well as swelling, suggests the possible involvement of inflammation in causing the condition. Although geneticists have not yet identified a clear genetic pattern, it is believed that reflex sympathetic dystrophy may have an inheritable component. Furthermore, psychological issues like depression and anxiety may precede or worsen the symptoms.
