Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this study is to present the author's thumb orthosis with a butonier deformity and its effect on hand function, strength, dexterity and pain levels in relation to patients wearing factory-made orthopedic supplies. It is planned to include about 60 people in the study (30 people each in the group with thermoplastic orthoses and 30 participants with factory-made orthoses)

The main questions it aims to answer are:

1\. How much improvement in dexterity will the patient wearing the orthosis get? 2. By how much will the grip strength of the whole hand and pincer grip strength improve with the orthosis? 3. How will wearing the orthosis affect the pain associated with the disease? Participants will

1. measurement of grip strength of the right and left hands with a dynamometer in an orthosis and without an orthosis, at the time of the test conducted and at the appointed times.
2. measurement of pincer grip strength with a dynamometer in an orthosis and without an orthosis, at the time of the test conducted and at the designated times.

4\. completion of the DASH questionnaire 6. assessment of the NRS pain scale in relation to the period of 6 months before the start of the study 7. Likert scale - evaluation of satisfaction with the use of the orthosis 8. the Kapandji scale Researchers will compare patients with thermoplastic orthosis and patients with fabric orthosis to see which is more functional.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Grip strength

Using a hydraulic handgrip dynamometer by Saehan according to the procedure to measure grip strength

Group Type OTHER

Thermoplastic orthosis

Intervention Type DEVICE

The use of the author's orthosis is aimed at correcting the anatomical alignment of the MP (metacarpophalangeal) joints, IP (interphalangeal) by properly tensioning the central extensor band and the lateral bands of the thumb's extensor apparatus. It should significantly increase the mobility of the hand in connection with improving hand grip and reducing pain.

DASH Questionnaire

The DASH questionnaire assesses upper limb disability and consists of 30 questions in the general section and an additional work module with 4 questions and a sport/instrument playing module with 4 questions. Assess symptoms and the inability to perform certain activities based on health status.

Group Type OTHER

Thermoplastic orthosis

Intervention Type DEVICE

The use of the author's orthosis is aimed at correcting the anatomical alignment of the MP (metacarpophalangeal) joints, IP (interphalangeal) by properly tensioning the central extensor band and the lateral bands of the thumb's extensor apparatus. It should significantly increase the mobility of the hand in connection with improving hand grip and reducing pain.

Likert scale

Measurement strategy, used in surveys to gain knowledge about the degree of acceptance of the orthosis

Group Type OTHER

Thermoplastic orthosis

Intervention Type DEVICE

The use of the author's orthosis is aimed at correcting the anatomical alignment of the MP (metacarpophalangeal) joints, IP (interphalangeal) by properly tensioning the central extensor band and the lateral bands of the thumb's extensor apparatus. It should significantly increase the mobility of the hand in connection with improving hand grip and reducing pain.

Kapandji score

Is a tool useful for assessing the opposition of the thumb

Group Type OTHER

Thermoplastic orthosis

Intervention Type DEVICE

The use of the author's orthosis is aimed at correcting the anatomical alignment of the MP (metacarpophalangeal) joints, IP (interphalangeal) by properly tensioning the central extensor band and the lateral bands of the thumb's extensor apparatus. It should significantly increase the mobility of the hand in connection with improving hand grip and reducing pain.

NRS scale

Requires the patient to rate their pain on a defined scale

Group Type OTHER

Thermoplastic orthosis

Intervention Type DEVICE

The use of the author's orthosis is aimed at correcting the anatomical alignment of the MP (metacarpophalangeal) joints, IP (interphalangeal) by properly tensioning the central extensor band and the lateral bands of the thumb's extensor apparatus. It should significantly increase the mobility of the hand in connection with improving hand grip and reducing pain.

Pinch strength
