Analysis identifies grip strength as an efficient assessment tool for upper limb function in rheumatic diseases, indicating potential for clinical use.
Grip strength is a key indicator of upper limb function impairment in RA and other rheumatic diseases. Given its strong association with disability and its dominance in variance explanation, grip strength measurement alone may serve as a time-efficient and reliable assessment tool, especially in resource-limited settings. Further research should validate grip strength as a primary clinical indicator and optimize assessment protocols for rheumatic patients.
