Exploring the Diverse Types of Splints in Occupational Therapy

In occupational therapy, splints serve as essential tools for aiding in the rehabilitation of hand injuries and various musculoskeletal conditions. These devices are often custom-made to fit an individual’s specific needs, providing support, immobilization, and functional assistance. Splints play a pivotal role in the recovery process, allowing patients to regain their strength, improve mobility, and prevent further complications.

Types of Splints

Static Splints

Static splints are designed to hold a joint in a fixed position. They are commonly used to immobilize a part of the body following an injury or surgery, aiding in the healing process. These splints are particularly beneficial for conditions requiring rest and stabilization, such as fractures, ligament injuries, and post-operative care.

Dynamic Splints

Unlike static splints, dynamic splints allow for controlled movement of the affected joint. They are typically used to improve range of motion and facilitate functional use of the hand and fingers. Dynamic splints employ springs, elastic bands, or other mechanisms to provide gentle, adjustable force, making them suitable for conditions like tendon injuries and joint stiffness.

Serial Casting

Serial casting involves the application of a series of progressive casts or splints to gradually increase range of motion or correct deformities. This technique is often utilized in the management of contractures, cerebral palsy, and other conditions where gradual stretching and repositioning are necessary. Each cast is typically changed every one to two weeks until the desired outcome is achieved.

Hand-Based Splints

Hand-based splints are designed to support specific areas of the hand without extending beyond the wrist. These splints are commonly used for conditions affecting the fingers and thumb, such as arthritis, ligament injuries, and nerve compressions. They provide targeted support while allowing for greater overall hand movement compared to full wrist or arm splints.

Thumb Splints

Thumb splints are specialized devices used to immobilize and support the thumb. They are commonly employed in the treatment of conditions such as thumb arthritis, ligament injuries, and De Quervain’s tenosynovitis. These splints help reduce pain, promote healing, and prevent further damage by restricting thumb movement.

Common Splinting Techniques

Fabrication Methods

Fabricating splints often requires a high degree of skill and precision. Occupational therapists typically use materials like thermoplastic, which can be molded when heated and retain their shape upon cooling. The process involves measuring, cutting, heating, and shaping the material to create a custom fit for the patient.

Fitting Guidelines

Proper fitting of splints is crucial for their effectiveness. Occupational therapists must ensure that the splint provides adequate support without causing discomfort or restricting blood flow. Regular adjustments may be necessary to accommodate changes in swelling or to improve the fit.

Duration of Wear

The duration for which a patient should wear a splint varies based on the condition being treated and the goals of therapy. Some splints may be worn continuously for several weeks, while others might be used only during specific activities or at night. Monitoring and adjusting the wear schedule is essential to maximize the therapeutic benefits.

The Top 5 Most Used Splints in Occupational Therapy

1. Resting Hand Splint

Description: A static splint that supports the wrist, fingers, and thumb in a neutral position.

Indications for Use: Commonly used for conditions like arthritis, stroke recovery, and post-surgical immobilization.

2. Finger Splint

Description: A small splint that immobilizes one or more fingers.

Indications for Use: Ideal for treating finger fractures, tendon injuries, and dislocations.

3. Wrist Cock-up Splint

Description: A splint that supports the wrist in a slight extension.

Indications for Use: Used for carpal tunnel syndrome, wrist fractures, and tendonitis.

4. Thumb Spica Splint

Description: A splint that immobilizes the thumb while allowing movement of the other fingers.

Indications for Use: Effective for thumb arthritis, sprains, and De Quervain’s tenosynovitis.

5. Dynamic Extension Splint

Description: A splint that uses elastic bands to encourage extension of the fingers.

Indications for Use: Useful for tendon repairs and improving range of motion in stiff joints.

Benefits of Using Splints in Therapy

Pain Management

Splints help alleviate pain by providing support and immobilization to injured or inflamed areas, reducing the need for pain medications.

Enhancing Functional Abilities

By stabilizing joints and supporting proper alignment, splints enable patients to perform daily activities with greater ease and efficiency.

Preventing Deformities

Regular use of splints can prevent the development of contractures and deformities, particularly in conditions like arthritis, stroke, and cerebral palsy.

Certification for Splinting in Occupational Therapy

Do you need certification to do splinting in occupational therapy? While not always mandatory, obtaining certification in splinting techniques can enhance an occupational therapist’s skills and credibility. Many professional organizations offer specialized courses and certifications in splinting.

Considerations

It is critical to make sure to monitor skin integrity when splinting. Be sure to educate the patient and caregivers on monitoring for signs of redness or pressure sores where the splint is applied. If redness or skin breakdown occurs, the patient should discontinue use and contact their occupational therapist for potential modifications of the splint. Assure the patient understands the wear schedule for the splint and how to don and doff appropriately for maximum benefit.

Conclusion

Splints are invaluable tools in occupational therapy, offering a multitude of benefits for patients recovering from hand injuries and other musculoskeletal conditions. From pain management to enhancing functional abilities, the versatility of splints makes them a crucial component of therapeutic interventions.
