Focal dystonia is a neurological condition and is a type of dystonia. The condition causes involuntary muscular contractions and abnormal postures occurring uncontrollably. A subset of this condition occurs in musicians, also known as the musician's cramp. An example would be that fingers will either curl into the pals or extend outwards without control.
This condition is very debilitating and very tricky to treat. The mainstay of treatment is therapy under a trained hand occupational therapist. Sensory re-education and sensory-motor re-tuning are the main modalities. In some cases, a hand and wrist specialist may intervene by administering Botox injections aimed to temporarily paralyse the specific muscle or group of muscles causing the dystonia.
