Summary

A total of 34 patients aged between 50-80 years, diagnosed with first carpometacarpal joint osteoarthritis based on hand radiographs taken within the last 3 months, will be included in the study from the Physical Therapy and Rehabilitation outpatient clinic. Sociodemographic data such as age, gender, height, weight, and BMI will be recorded. Based on their current radiographs, patients will be classified into two groups according to the Eaton-Littler classification: Stage 1-2 (early stage) and Stage 3-4 (advanced stage). Pain levels will be assessed using the Visual Analog Scale (VAS). Hand grip strength will be evaluated with a Jamar hand dynamometer, and pinch grip strength will be assessed with a Jamar pinch meter. The thicknesses of the abductor pollicis brevis, first dorsal interosseous, and opponens pollicis muscles will be measured using ultrasound. All assessments will be performed separately for the dominant and non-dominant hands.
