Brief Summary

This study investigated the relationships between core endurance, finger grip strength, fatigue, and hand function in patients with rheumatoid arthritis.

Conditions

Rheumatoid Arthritis; Healthy Control

Keywords

Rheumatoid Arthritis; Core Endurance; Pinchmeter; Grip Strength; Fatigue

Outcome Measures

Primary Outcomes (1)

• Core endurance

  Modified prone plank. This test began with a crawling position, and the participant was instructed to lift their knees off the ground and maintain that position.

  December 2022-September 2023

Secondary Outcomes (4)

• Finger grip strength

  December 2022-September 2023

• Hand function

  December 2022-September 2023

• Fatigue severity

  December 2022-September 2023

• Physical activity level

  December 2022-September 2023

Study Arms (2)

RA group

Core endurance, finger grip strength, hand function, fatigue, physical activity level, and disease activity were evaluated in patients diagnosed with RA.

Healthy controls

Core endurance, finger grip strength, hand function, fatigue, and physical activity level were evaluated in healthy control

Eligibility Criteria

• Age: 18 Years - 65 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

Patients RA diagnosis and health Controls

• Having a serious deformity or severe pain in the extremities or trunk that would prevent taking a crawling position (7 or higher on a 10-point numerical pain scale) (being present)
• Hand deformity or pain severe enough to prevent finger grip strength measurements
• History of any serious trauma or injury within the last 6 months
• Changes in medication used for RA within the last 3 months
