Focal dystonias involving  are commonly misdiagnosed A provider can consider to rule in or out Dopamine-responsive dystonia with a levodopa trial. Treatment
Treatment options would be based on the type of focal dystonia the patient has. If possible, incorporating rest earlier to symptom onset has shown to have greater improvement in symptoms for Writers cramp. Physical Therapy
Physical therapy is commonly used as an adjunct or main form of treatment for focal dystonia, however more studies for its benefit are needed. Bass guitarist and instructor Scott Devine said that he wears a glove while playing bass guitar because of the condition. He finds that the glove stops the involuntary finger movements. He says it works for him but does not suggest that it may work for everyone with the condition. Medications
Anticholinergics such as Artane can be prescribed for off-label use, as some patients have had success. Benzodiazepines, such as Clonazepam, can be used as a muscle relaxant. Other oral medications have been studied for different types of focal dystonia, such as baclofen, tetrabenazine, amantadine, antipsychotics, and amphetamine

Procedures
This condition is often treated with injections of botulinum neurotoxin type A (BoNT/A). BoNT/A reduces the symptoms of the disorder but it is not a cure for dystonia. Since the root of the problem is neurological, doctors have explored sensorimotor retraining activities to enable the brain to "rewire" itself and eliminate dystonic movements.
Also, synchronous afferent stimulation of peripheral muscles induces organizational changes in motor representations, characterized both by an increase in map size of stimulated muscles and a reduction in map separation, as assessed using transcranial magnetic stimulation.The cross-connectivity between areas that are normally segregated in the sensory cortex may prevent normal sensorimotor feedback and so contribute to the observed co-contraction of antagonist muscle groups, and inappropriately timed and sequenced movements that underlie the symptoms of focal dystonia. It is hypothesized that a deficit in inhibition caused by a genetically mediated loss of inhibitory interneurons may be the underlying cause of the deficits observed in dystonia.While usually painless, in some instances the sustained contraction and abnormal posturing in dystonia cause pain. Focal dystonia most typically affects people who rely on fine motor skills—musicians, writers, surgeons, etc. It is thought that the excessive motor training those skills require may contribute to the development of dystonia as their cortical maps become enlarged and begin to overlap. Focal dystonia is generally "task-specific," meaning that it is only problematic during certain activities. Diagnosis
The diagnosis of focal dystonia is highly dependent on the history of the patient, as physical exam is typically normal, and ruling out other causes of movement disorder. The main types of are blepharospasm, oromandibular dystonia, spasmodic dysphonia, spasmodic torticollis, and limb dystonia, all affecting a different region of the body. Labs and imaging may be ordered as workup to evaluate for other causes of dystonia.
