About

This study is a randomised control trial and the purpose of this study is to compare the effects of Sub-maximal Voluntary Isometric Training vs Eccentric Training in Management of De Quervain Tenosynovitis

Full description

Participants will be recruited into their respective groups using a coin toss method. De Quervain Tenosynovitis will be assessed using the following tests:

1. Wrist hyperflexion and abduction of thumb (WHAT) test
2. Finkelstein's / Eichhoff's test
3. De Quervain Screening Tool

Enrollment: 58 estimated patients

Sex: All

Ages: 21 to 50 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Patients having history of pain, tenderness in thumb region from 3 weeks or more
• Age 21-50
• Both genders
• Individuals meeting the diagnostic criteria i.e.
• A score of 3 or more out of 7 on De Quervain screening tool.
• Positive Wrist hyperflexion and abduction of thumb (WHAT) test
• Positive Finkelstein's / Eichhoff's test

Exclusion criteria

• Diagnosed cases of Osteoarthritis of 1st CMC joint and Rheumatoid arthritis
• C6 cervical radiculopathy
• Any systemic inflammatory condition like septic arthritis
• Carpal Tunnel Syndrome
• Complex regional pain syndrome
• Previous surgery impacting the first extensor compartment of the wrist
• Corticosteroid injection in the radial wrist region within 3 months of enrolment into the study
• If patient had undergone isometric thumb exercises or any strengthening protocol lasting greater than 2 weeks for the management of their current episode of de Quervain's syndrome

58 participants in 2 patient groups

Sub-maximal Voluntary Isometric training Group

Active Comparator group

Description:

Group A will recieve ultrasound therapy for symptoms management and isometric training of thumb muscles (abducttor pollices longus and extensor pollices brevis) to gain improvement in range of motion and strength

Treatment:

Procedure: Isometric training of thumb muscles

Procedure: Ultrasound

Eccentric training Group

Experimental group

Description:

Group B will receive the ultrasound therapy similar to group A for symptoms management and eccentric training of thumb muscles to gain improvement in range of motion and strength of thumb

Treatment:

Procedure: Ultrasound

Procedure: Eccentric training for thumb muscles
