Essay / Amputation: A Phantom Limb - 1566
Amputation often causes patients to experience sensory illusions that the limb is still present. This is often called a phantom limb. This feeling of having a phantom limb is a natural and common development during amputation recovery. (1) (2) It is reported that at first the phantom limb appears normal in size and shape, but over time this illusion of the size of the phantom limb usually becomes smaller. (1) Phantom limb pain is a painful sensation experienced. in a part of the body that is no longer part of the body, often due to amputation.(3) People have also reported tingling as well as various types of pain, and these sensations may eventually disappear or persist as cramps , shooting, burning or crushing sensations.(1) (4) Various studies report that phantom limb pain occurs in 0.4 to 90 percent of cases.(1) (2) (4) (5 ) (6) Recently, it has been found that phantom limb pain occurs in approximately 50-85% of patients several months or years after amputation, rather than immediately after amputation.(1) (4) Studies have shown that phantom limb pain is closely related to the somatosensory cortex.(2) (4) There is evidence that limb amputation results in cortical reorganization and that phantom limb pain may be related to a incongruence between motor intention, somatosensation and visual feedback. (4) Cortical contributions to phantom limb pain come from various studies that show neuroplastic changes in the primary somatosensory and motor cortices after amputation. (4) Treatment of phantom limb pain is difficult, and no specific treatment method has been confirmed. (1) (4) (5) Treatment of phantom limb pain includes medications, various forms of physical treatment, nerve blockade.... ... middle of paper ...... phantom limb pain. While mirror therapy uses visuomotor stimulation and is found to be beneficial depending on the type of pain experienced, illusory touch uses visuotactile stimulation and is considered effective in patients who typically experience pain with movement. stimulation is imported into the effectiveness of the sensations experienced in the phantom limb. It is also evident that further research needs to be conducted into both treatment mechanisms and that the role of occupational therapy in the use of these treatment modalities is not well documented although it is a clear role of occupational therapy in the treatment of phantom limb. pain. Most studies document the use of mirror therapy in occupational therapy as it relates to movement of a limb rather than its use in treating sensation..
