Parkinson’s disease falls under the category of hypokinetic movement disorders, resulting from damage to many nerve cells in the brain, starting in the lower part of the brainstem and then spreading to the cerebrum. The four main symptoms that occur are bradykinesia, rigidity, tremor, and postural instability. The extrapyramidal system is responsible for maintaining postural tone, regulating motor skills and coordination of larger muscle groups, i.e. it controls the unconscious component of voluntary motor activity. The ability of the brain to change or adapt to new situations is called brain neuroplasticity. PD is a disease that occurs in all ethnic groups, races and both sexes, but men have a 1.5 times greater chance of developing the disease than women. The etiology of PD is still not fully explained, but the main role is played by the interaction between environmental and genetic factors. PD can be divided into three main groups: type A (tremor dominant type), type B (akinetic type) and type C (mixed type). There is still no specific method for diagnosing PD, so the diagnosis of the disease is based on a detailed clinical examination by a neurologist. There is no cure for complete recovery from PD, so treatment focuses on improving the quality of life of patients, and medication treatment is most commonly used where levodopa, amantadine, anticholinergics and dopamine agonists are most commonly used and neurosurgical treatment where deep brain stimulation (DBS), thalamotomy and pallidotomy are applied. Before planning therapy for a patient, it is important to assess his condition at the very beginning so that the physiotherapist can use the S.O.A.P. model of planning where he takes the patient’s history, performs various tests and measurements and finally analyzes the data and sets up a rehabilitation plan. The main goal is to facilitate the daily life of patients so therapeutic exercises used are stretching, breathing, strengthening and coordination exercises as well as electrotherapy, massage, Bobath, PNF and recreational activities.
