UMIN ID: UMIN000054354

Registered date:09/05/2024

Basic Information

• Recruitment status: Pending
• Health condition(s) or Problem(s) studied: Thumb CM arthropathy
• Date of first enrollment: 2024/05/09
• Target sample size: 48
• Countries of recruitment: Japan
• Study type: Interventional

Intervention(s)

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 position using a splint during the first postoperative week.
palmar 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 palmar abduction position using a splint during the first postoperative week.
Conservative treatment group Surgery is not performed, and treatment includes exercise and orthotic therapy.

Outcome(s)

• Primary Outcome: 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 Outcome: 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)

Key inclusion & exclusion criteria

• Age minimum: 18years-old
• Age maximum: Not applicable
• Gender: Female
• Exclude 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.
