简要总结
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.Patients with Parkinson's disease (pwPD) often exhibit poor manual dexterity and decreased strength. Fine motor deficits seen in PD include an inability to control cognitive power/force, poor manual dexterity, and motor dysfunction, which includes difficulties achieving the angles, speed, and coordination required for basic movements. Anatomical strength, as detailed in activities of daily living (ADL), is an important indicator of motor characteristics and vitality.Studies have shown a strong relationship between postural control and fine motor functions. For high-quality distal movement, better proximal stabilization is necessary. During upper extremity functions, the body's center of gravity must shift with arm movements, allowing adaptation to changing gravity. Good trunk control is essential in this dynamic process of maintaining balance. Studies examining this link between trunk control, balance, and hand functions are available in the literature. Among these studies conducted in diverse populations, studies involving PD are very few. Investigating parameters such as grip strength, upper extremity dexterity, and reaction time in PD will fill the gap in the literature. Meta-analysis studies have shown that muscle strength and strength in individuals with PD are lower than in healthy individuals. Furthermore, muscle strength in PD has been shown to be related to functional capacity and disease severity. In light of all this information, our study was designed to investigate the relationship between upper body muscle strength, particularly proximal and distal, and manual dexterity in PD. In this direction, the aim of this study is to determine the relationship between proximal and distal muscle strength and upper extremity functional abilities in PD.

主要结局
Muscle Strength Measurement
时间窗: first day of assesment
The isometric strength measurement will be performed using a digital muscle strength measurement device (KFORCE KINVENT) for the bilateral serratus anterior, upper trapezius, latissimus dorsi, deltoid, supraspinatus, teres minor, subscapularis, and biceps brachii muscles of the upper extremity.
Grip Strength Measurement
时间窗: first day of assesment
A Jamar hand dynamometer (Baseline®) and a PinchMeter (Baseline Mechanical Pinch Gauge with Case, Blue, 30 lb) will be used for grip strength measurement.The isometric strength measurement will be performed using a digital muscle strength measurement device (KFORCE KINVENT) for the bilateral serratus anterior, upper trapezius, latissimus dorsi, deltoid, supraspinatus, teres minor, subscapularis, and biceps brachii muscles of the upper extremity.

The 9-Hole Peg Test (DDPT)
时间窗: first day of assesment
The 9-Hole Peg Test (DDPT) is a validated test for PD that measures manual dexterity in seconds based on performance. The test material consists of nine standard-sized small rods and a nine-hole platform. The test will be administered with the patient in a seated position. The patient will be asked to place nine rods in the round compartment of the box as quickly as possible into the holes of the box, starting from the edge farthest from the compartment. Once completed, immediately remove them from the compartment, starting from the edge closest to the compartment. The test will begin with the dominant hand, and the time will be measured with a stopwatch. The time will begin when the hand touches the rods and will end when the last rod is placed in the box. The same procedure will be applied to the other hand. In this study, the arithmetic average of the test times, repeated twice, will be recorded separately for each hand.
