Summary

This study was planned to evaluate the effect of psoriatic arthritis on the strength, proprioception, skill, coordination, and functional condition of the hand and to determine the correlate disease activity with these parameters.

Detailed description

Psoriatic arthritis (PsA) is a chronic, progressive, inflammatory arthritis that occurs as a condition associated with patients with psoriasis and may result in permanent joint damage and an increased risk of mortality. Synovial membrane inflammation characterized by increased vascularization and immune cell infiltration is an important feature of psoriatic arthritis. This inflamed synovial microenvironment leads to the formation of synovial pannus, entheseal inflammation, and joint damage. Although PsA is generally thought of as a benign arthropathy, structural damage has been shown with the progression of the disease, along with joint inflammation.As a result of the researches, it has been stated that tissue biomechanical stress and microtraumas that lead to the activation of abnormal natural immune responses in psoriatic arthritis can trigger joint inflammation. In parallel, inflammation is expected to be more common in peripheral joints, which are known to be more exposed to microtrauma. Studies have reported that hand joint involvement is frequently seen in patients with PsA and is an important cause of loss of function and that erosions in hand joints are associated with statistically significant loss of hand strength. Theoretically, either the mechanical effect of the fluid in the acute joint effusion or the components of the inflammatory fluid and the changing capsular compliance after chronic effusion and has been reported that problems may occur in proprioception due to causes such as pain, trauma, and fatigue. However, pain, decreased joint ROM and grip strength, muscle weakness, and hand deformities can affect hand fine hand skills and function. The hypothesis of this study is that supporting the clinical condition of the participants with parameters related to general hand function will be effective in predicting disease progression and disability. Accordingly, the aim of the researchers is to evaluate the effect of PsA on the grip and pinch strength of the hand, proprioception, skill, coordination and functional status, and to determine the relationship of disease activity with these parameters.

Conditions

• Psoriatic Arthropathy Hand
• Psoriatic Arthritis

Interventions

Type	Name	Description
OTHER	Assessment of strength, proprioception, skill and coordination of the hand	Disease Activity Score 28 was used to determine the disease activity of patients with PsA. Grip strength was measured with the help of Baseline Digital Hand Dynamometer®. Pinch strength was measured with Baseline Hydraulic Pinch Gauge®. Wrist proprioception was assessed by measuring the joint position sensation using a goniometer by actively repeating the target angle predetermined by the researcher (30 ° for flexion and extension, 15 ° for ulnar deviation, 10 ° for radial deviation. Finger skills were assessed using a mobile application called Ball Tap©. The application included the fastest contact of the participants to the balls coming from different parts of the screen for 30 seconds. Two hand coordination and skills were evaluated using the Purdue Pegboard test. The Michigan Hand Outcomes Questionnaire was used for functional evaluation of the hand, and the Health Assessment Questionnaire was used to assess the general functional condition and health-related quality of life.
