radial abduction group During the 3-week postoperative immobilization period, the limb was immobilized using a splint for the first postoperative week, and the limb was placed in radial abduction pos

Eligibility

Sex/Gender

Female

Inclusion criteria

Inclusion criteria: (a) Patients who are at least 18 years of age (adult) at the time of enrollment and have no cognitive impairment that would preclude their consent to participate in the study. (b) Female patients diagnosed with CM arthropathy of the thumb and scheduled for conservative treatment and surgery (plasty).

Exclusion criteria

Exclusion criteria: Patients with neurological symptoms such as complex regional pain syndrome, patients with a history of surgery on the thumb, and patients who have undergone procedures or surgery that may affect postoperative ROM such as joint fusion surgery.

Design outcomes

Primary

Measure	Time frame
Range of motion(ROM) in preoperative and postoperative evaluations (automatic or passive range of motion of thumb radial abduction, ulnar adduction, palmar abduction, palmar adduction, metacarpophalangeal(MP) joint flexion/extension, interphalangeal(IP) joint flexion/extension) difference	—

Secondary

Measure	Time frame
Preoperatively and postoperatively (a) Differences in muscle strength such as pinch strength (finger pads/flanks) and grip strength (b) Differences in thumb opposition function based on kapandji score (c) Difference in pain based on Visual Analogue Scale(VAS) (rest, exercise, and weight bearing) (d) Comparison of functional evaluation of hand pathology using Michigan Hand Outcomes Questionnaire(MHQ) (e) Differences in upper limb function based on Simple Test for Evaluating Hand Function(STEF) and modified STEF (f) Comparison of muscle activity using surface electromyogram (integral value of thenar muscle) (g) Comparison of muscle contraction during exercise using ultrasound examination (muscle thickness of thenar muscle) (h)Mini Mental State Examination (i)Purdue Pegboard Test	—
