Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Parkinson's disease (PD) is the second most common neurodegenerative disease, characterized pathologically by the progressive loss of dopaminergic neurons in the substantia nigra and clinically by the presence of motor symptoms such as bradykinesia, resting tremor, and/or rigidity. Among the motor deficits frequently observed in PD, patients are known to frequently report difficulties with manual dexterity. Many upper extremity and manual dexterity deficits are present in PD. Motor imagery (MI) is the imaginal execution of motor activities or the activation of specific muscles in the absence of any explicit feedback. This area of rehabilitation has been shown to be effective in improving and developing motor skills in many neurological conditions where patients exhibit motor recognition and execution impairments. MI can be applied at all stages of recovery from PD, is highly effective in movement-related pathologies, and can be performed independently.There is sufficient evidence that MI improves motor performance and learning in individuals with neurological disorders such as multiple sclerosis, stroke, and spinal cord injury. The study was designed to investigate the immediate effects of mental imagery, which is thought to be effective in controlling difficulties in planning and initiating movements in PD, on upper extremity skills. Therefore, the aim of this study was to determine the effect of mental imagery on upper extremity skills in PD.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

1/study group

Upper extremity skill tests will be performed on individuals diagnosed with idiopathic Parkinson's disease and recorded with a mental stopwatch using mental imagery.

Group Type EXPERIMENTAL

mental imagination

Intervention Type OTHER

The Nine-Hole Peg Test (9 DPT) will be performed with a mental chronometer.the duration between actually physically performing the movement and mentally imagining the same movement will be recorded.

2/control group

Upper extremity skill tests will be performed on individuals diagnosed with idiopathic Parkinson's disease.

Group Type NO_INTERVENTION

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Healthy individuals aged 40-75 years, diagnosed with idiopathic PD according to the UK Parkinson's Disease Association Brain Bank criteria by a specialist neurologist, with a Modified Hoehn \& Yahr (m-HY) scale stage ≤4, and with a Mini Mental State Examination score of ≥24 for those with training and ≥18 for those without training, and with no known disease, volunteered to participate in the study.
* PD individuals with no other known neurological and/or systemic disease
* PD individuals without any upper extremity contractures

Exclusion Criteria

* Individuals with diagnosed and/or treated psychiatric illnesses who are considered unable to complete the tests.
* Individuals who is taking neuroleptic medications or antidepressants.
* Individuals with orthopedic conditions that interfere with manual dexterity tests, such as severe dyskinesia, carpal tunnel syndrome, tendon injuries, or finger amputations; rheumatological conditions such as rheumatoid arthritis and osteoarthritis; and individuals with any neurological condition other than PD.
