Individuals with an intrinsic plus hand will demonstrate difficulty gripping large objects. Diagnosis is made by clinical exam which shows MCP flexion and IP joint extension For dorsal and volar burns, the therapist should flex the MCPs into 70 to 90 degrees, fully extend the PIP joints and DIP joints, and palmarly abduct the thumb to the index and middle fingers with the thumb IP joint extended [Salisbury et al. Several splints are designed to reduce spasticity. summary. For a person who has severe deformities or exacerbations from arthritis, the resting hand splint may also position the wrist at neutral or slight extension and 5 to 10 degrees of ulnar deviation [Geisser 1984, Marx 1992]. Existing neural pathways can be strengthened and new ones created with the help ofneuroplasticity, the central nervous systems ability to repair itself. Figure 9-4 This resting hand splint is fabricated of soft materials and includes a dorsal forearm base design. summary. For children, splints are removed for exercise, hygiene, and play activities [deLinde and Miles 1995]. Table 1: Commonly Use Splints for people with Spinal Cord Injury Type of Splint Purpose Donning and Doffing Resting Splint To keep a hand in a functional position with wrist and fingers Intrinsic plus hand is a contracture of the intrinsic hand muscles characterized by excessive flexion at the metacarpophalangeal (MCP) joints and extension at the interphalangeal (IP). After a burn injury, the thumb web space is at risk for developing an adduction contracture [, The emergent phase is the first 48 to 72 postburn hours [deLinde and Miles 1995]. This can include more specific splints such as elbow extension splints, elbow pillow splints, anti-spasticity splints, and intrinsic plus or minus splints. Some of the commercially sold resting hand splints are prefabricated, premolded, and ready to wear. Functional position To compensate for weak or paralyzed muscles of the upper body, survivors can use hand splints for spinal cord injury. 1List diagnoses that benefit from resting hand splints (hand immobilization splints). Describe the functional or mid-joint position of the wrist, thumb, and digits. The more the central nervous system is stimulated, the more neuroplasticity can create and strengthen neural pathways needed to restore hand function. When the volar surface of the forearm must be avoided because of sutures, sores, rashes, or intravenous needles, a dorsally based forearm trough design is frequently used (. Ball splints implement a reflex-inhibiting posture by positioning the wrist in neutral (or slight extension) and the fingers in extension and abduction. Performance Health features professional-grade hand therapy supplies for sale. Resting Hand Splint Positioning Limb elevation is crucial, and care must be taken to avoid applying compressive dressings such as Ace wraps or restrictive circular casts. Design by Elementor, Hand Splints for Spinal Cord Injury: How to Choose the Right Fit for You, therapeutic exercises for spinal cord injury. An advantage of. The forearm trough can be used as a lever to extend the wrist in addition to extending the fingers. Complex regional pain syndrome Figure 9-6 Volar-based resting hand splint: (A) side view, (B) volar view. (Progress Dorsal Anti-Spasticity splint; courtesy North Coast Medical, Inc., Morgan Hill, California.) Static splinting is initiated during the emergent phase to support the hand and maintain the length of vulnerable structures [deLinde and Miles 1995]. Describe the antideformity or intrinsic-plus position of the wrist, thumb, and digits. Medical Therapy. When splinting a joint with chronic RA, the rationale is often based on biomechanical factors. The phases of recovery are emergent, acute, skin grafting, and rehabilitation. When fabricating a custom splint for a person with excessive edema, a therapist should avoid forcing wrist and hand joints into the, Persons with hand burns have bandages covering burn sites. After a burn injury, the thumb web space is at risk for developing an adduction contracture [Torres-Gray et al. As the patient moves into the subacute phase, static splinting should continue to prevent shortening of soft tissue, especially if tone is an issue, and . During this time frame, dorsal edema occurs and encourages wrist flexion, MCP joint hyperextension, and IP joint flexion [deLinde and Miles 1995]. Splints can aid in your spinal cord injury recovery, but require the assistance of other therapies to maximize your chances of restoring function. For persons who have hand burns, therapists do not splint in the functional position. Similar to premolded splints, precuts from perforated materials contain perforations in only the body of the splint. Cone splints combine a hand cone and a forearm trough, which maintains the wrist in neutral, inhibits the long finger flexors, and maintains the web space (, A resting hand splint positioning the hand in a functional position is also advocated for spasticity (. Joints that are receptive to proper positioning may allow for optimal maintenance of range of motion (ROM) [Ziegler 1984]. According to Lau [1998, p. 47], The exact specifications of the functional position of the hand in a resting hand splint and the recommended joint positions vary. One functional position that we suggest places the wrist in 20 to 30 degrees of extension, the thumb in 45 degrees of palmar abduction, the metacarpophalangeal (MCP) joints in 35 to 45 degrees of flexion, and all proximal interphalangeal (PIP) and distal interphalangeal (DIP) joints in slight flexion. Tenodesis splints are designed to help tighten the soft tissues of the hands that become loose when the muscles are not working properly. [1994, p. 370], As layers of bandage around the hand increase, accommodation for the increased bandage thickness must be accounted for in the splints design, if it is to fit correctly. To correct for bandage thickness on a resting hand splint, the bend corresponding to MCP flexion in the pan should be formed more proximally [Richard et al. If a child is age three or older, splinting should be considered. The antideformity position places the wrist in 30 to 40 degrees of extension, the thumb in 40 to 45 degrees of palmar abduction, the thumb IP joint in full extension, the MCPs at 70 to 90 degrees of flexion, and the PIPs and DIPs in full extension (Figure 9-9). 5Identify the components of a resting hand splint (hand immobilization splint). Precuts are interchangeable for right or left extremity application. Hand Therapy and Splinting. Additional splint data collected in 1994 from 46 international SCI rehabilitation centers indicates, resting hand splints were prescribed to promote functional positioning, maintain joint . A disadvantage is that the pattern is not customized to the person. Typical joint placement for splinting a person with RA positions the wrist in 10 degrees of extension, the thumb in palmar abduction, the MCP joints in 35 to 45 degrees of flexion, and all the PIP and DIP joints in slight flexion [Melvin 1989]. 2001]. Thus, a wide range of designs exists for splinting dorsal hand burns [Richard et al. The volarly based forearm trough at the proximal portion of the splint supports the weight of the forearm. The biomechanical rationale for splinting acutely inflamed joints is to reduce pain by relieving stress and muscle spasms. During this time frame, dorsal edema occurs and encourages wrist flexion, MCP joint hyperextension, and IP joint flexion [deLinde and Miles 1995]. These off-the-shelf splints are made in a variety of shapes and sizes and are much easier and faster to use. Although hand immobilization splints are commonly used, a paucity of literature exists on their efficacy. Your therapist can also provide more guidance on which hand therapy exercises and hand splints are appropriate for you. Design to optimally position the hand in an intrinsic-plus position after a burn injury. However, if the perforated premolded or precut splint must be trimmed through the perforations a rough edge may result. Persons who require resting hand splints commonly have arthritis [Egan et al. My occupational therapist recommended to give this a try. Until now, therapists had only one choice. Commercially available products such as the Rolyan Aquaplast UltraThin Edging Material can be applied over the rough edges to help create a smooth-edged reinforcement on splints fabricated from Aquaplast materials [Sammons Preston Rolyan 2005]. When tolerable, the resting hand splint for the person who has hand burns can be adjusted more closely to the ideal position. The therapist should apply biomechanical principles to make the trough about two-thirds the length of the forearm to distribute pressure of the hand and to allow elbow flexion when appropriate. The width and depth of the thumb trough should be one-half the circumference of the thumb, which typically should be in a palmarly abducted position. Finger spacers may be used in the pan to provide comfort and to prevent finger slippage in the splint [, In persons who have RA, the use of splints for purposes of rest during pain and inflammation is controversial [Egan et al. On average, survivors complete hundreds of repetitions per half hour session. Rolyan's New Look. Typical joint placement for splinting a person with RA positions the wrist in 10 degrees of extension, the thumb in palmar abduction, the MCP joints in 35 to 45 degrees of flexion, and all the PIP and DIP joints in slight flexion [Melvin 1989]. Based on the nature of the spinal cord injury, incomplete injuries can expect to make improvement of hand motion and strength. Clinicians customize splint position based on muscle tone, ability to perform a functional grasp, and remaining active finger motion. 7Determine a resting hand (hand immobilization) splint-wearing schedule for different diagnostic indications. For dorsal and volar burns, the therapist should flex the MCPs into 70 to 90 degrees, fully extend the PIP joints and DIP joints, and palmarly abduct the thumb to the index and middle fingers with the thumb IP joint extended [Salisbury et al. According to Richard et al. 2001]. For persons who have hand burns, therapists do not splint in the functional position. The therapist must know the splints components to make adjustments for a correct fit. The proximal end of the trough should be flared or rolled to avoid a pressure area. Figure 9-8 A resting hand splint with the hand in a functional (mid-joint) position. Resting hand splints immobilize the wrist, thumb, and metacarpophalangeal (MCP) joints to provide rest and reduce inflammation. Therapists use clinical judgment to determine what joint angles are positions of comfort for splinting. The resting hand splint has three purposes: to immobilize, to position in functional alignment, and to retard further deformity [Malick 1972, Ziegler 1984]. Any injury to the hand can lead to intrinsic contracture. The intrinsic plus position is otherwise known as the safe position for hand splinting. The proximal interphalangeal (PIP) and distal interphalangeal (DIP) joints are free to move for functional tasks. Thus, a wide range of designs exists for splinting dorsal hand burns [Richard et al. The pan should be wide enough to house the width of the index, middle, ring, and little fingers when they are in a slightly abducted position. Splints also helps maintain the normal appearance of the hands by supporting proper positioning. Charcot-Marie-Tooth disease (hereditary motor-sensory neuropathy . (Preformed Anti-Spasticity Hand Splint; courtesy North Coast Medical, Inc., Morgan Hill, California. 4List the purposes of a resting hand splint (hand immobilization splint). When a great amount of forearm support is desired, a volarly based forearm trough is the best design (Figure 9-6). Positioning may vary, depending on the surface of the hand that is burned. A resting hand splint is recommended to keep your child's hand in an open position. Persons in late stages of RA who have skeletal collapse and deformity may benefit from the support of a splint during activities and at nighttime [Biese 2002, Callinan and Mathiowetz 1996]. The therapist should apply biomechanical principles to make the trough about two-thirds the length of the forearm to distribute pressure of the hand and to allow elbow flexion when appropriate. For example, the hands of a survivor with quadriplegia may be more prone to overstretching, stiffness of joints, tightening of tissues, or developing joint contractures due to impaired motor function. Explain the precautions to consider when fabricating a resting hand splint (hand immobilization splint). The best hand splints for spinal cord injury include: 1. 2001, Ouellette 1991]; postoperative Dupuytrens contracture release [Prosser and Conolly 1996]; burn injuries to the hand, tendinitis, hemiplegic hand [Pizzi et al. However, research indicates that some persons with RA who wore their splints only at times of symptom exacerbation did not demonstrate negative outcomes in relation to ROM or deformities [Feinberg 1992]. 9Apply knowledge about the application of the resting hand splint (hand immobilization splint) to a case study. Thus, it is a ripe area for future research. 2005]. 2005]; and tenosynovitis [Richard et al. 2. A 45-year-old carpenter complains of difficult gripping a hammer, which worsens with repeated use. A disadvantage is that customization may require more of the therapists time to complete the splint and may be more costly. Studies on animals indicate that immobilization leads to decreased bone mass and strength, degeneration of cartilage, increase in joint capsule adhesions, weakness in tendon and ligament strength, and muscle atrophy [Falconer 1991]. This is the lowest region where full movement and sensation remain. 1. CHAPTER 9 Diagnosis is made clinically by observing the resting posture of the hand to assess the digital cascade and the absence of the tenodesis effect. Below we have listed the most effective and commonly prescribed by therapists. Thus, it is a ripe area for future research. For a person who has severe deformities or exacerbations from arthritis, the resting hand splint may also position the wrist at neutral or slight extension and 5 to 10 degrees of ulnar deviation [, Note that wrist extension varies from the typical 30 degrees of extension.
