resting hand splint vs intrinsic plus
Your therapist can also provide more guidance on which hand therapy exercises and hand splints are appropriate for you. MCP joint dislocations and ulnar deviation lead to spastic intrinsics, leads to flexion of the MCP and extension of the IP joints, fails to provide balancing extension force to MCP joint, fail to provide balancing flexion force to PIP and DIP joints, differentiates intrinsic tightness and extrinsic tightness, no radiographs required in diagnosis or treatment, less severe deformities when there is some remaining function of the intrinsics (e.g., spastic intrinsics), more severe deformity involving both MCP and IP joints, dysfunctional intrinsic muscles (e.g., fibrotic), subperiosteal elevation of interossei lengthens muscle-tendon unit, resection of intrinsic tendon distal to the transverse fibers responsible for MCP joint flexion, Lunate Dislocation (Perilunate dissociation), Gymnast's Wrist (Distal Radial Physeal Stress Syndrome), Scaphoid Nonunion Advanced Collapse (SNAC), Carpal Instability Nondissociative (CIND), Constrictive Ring Syndrome (Streeter's Dysplasia), Thromboangiitis Obliterans (Buerger's disease). Burn resting hand splints typically position the wrist in 20 to 30 degrees of extension, the MCP joints in 60 to 80 degrees of flexion, the PIP and DIP joints in full extension, and the thumb midway between radial and palmar abduction (Figure 9-2). Therapists fabricate custom resting hand splints or purchase them commercially. 3Describe the antideformity or intrinsic-plus position of the wrist, thumb, and digits. The resting hand splint has three purposes: to immobilize, to position in functional alignment, and to retard further deformity [Malick 1972, Ziegler 1984]. The proximal interphalangeal (PIP) and distal interphalangeal (DIP) joints are free to move for functional tasks. An advantage of premade splints is their quick application (usually only straps require application). The antideformity position for a palmar or circumferential burn places the wrist in 30 to 40 degrees of extension and 0 degrees (i.e., neutral) for a dorsal hand burn. Metacarpal-phalangeal blocking (MCP) splints help to promote proper motion of the finger during functional hand tasks. This can be caused by trauma, arthritis or neurological deficits. This is most often accomplished by overnight wear of a static resting hand splint, in a neutral or intrinsic-plus position, or with an antispasticity splint, in the presence of hypertonicity. (Preformed Anti-Spasticity Hand Splint; courtesy North Coast Medical, Inc., Morgan Hill, California. To use other devices, discuss with your therapist as custom splints may be required. 2 types of positioning are achieved by a resting hand splint: a functional (mid-joint) position and an antideformity (intrinsic-plus/safe) position. The resting hand splint maintains the hand in a functional or antideformity position, preserves a balance between extrinsic and intrinsic muscles, and provides localized rest to the tissues of the fingers, thumb, and wrist [Tenney and Lisak 1986]. Application: 1. Splints can either bedynamic, meaning they allow movement, or they can bestaticwhich means they are in a fixed position. using a kit is the time the therapist saves by elimination of pattern making and cutting of thermoplastic material. The therapist must know the splints components to make adjustments for a correct fit. Positioning may vary, depending on the surface of the hand that is burned. Below we have listed the most effective and commonly prescribed by therapists. A new radiograph is shown in figure A. In persons who have RA, the use of splints for purposes of rest during pain and inflammation is controversial [Egan et al. A resting hand splint is a static splint that immobilizes the fingers and wrist. Therefore, the precut splint may require many adjustments to obtain a proper fit. The volarly based forearm trough at the proximal portion of the splint supports the weight of the forearm. Physicians commonly order resting hand splints, also known as hand immobilization splints [American Society of Hand Therapists 1992] or resting pan splints. Efforts must be directed at decreasing edema in the injured hand. This splint is based on a resting hand splint design and is often used for individuals with rheumatoid arthritis. 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. A resting hand splint is recommended to keep your child's hand in an open position. Many products are advertised to save time and to be effective, but few studies compare splinting materials when used by therapists with the same level of experience [Lau 1998]. Describe the functional or mid-joint position of the wrist, thumb, and digits. Several splints are designed to reduce spasticity. Kits are available according to hand size (i.e., small, medium, large, and extra large). If the web space tightens, it inhibits cylindrical grasp and prevents the thumb from fully opposing the other digits. For children, splints are removed for exercise, hygiene, and play activities [deLinde and Miles 1995]. While in a complete spinal cord injury there may be no unaffected neural pathways remaining, an incomplete spinal cord injury has potential for regaining movement during rehabilitation. If a child is age three or older, splinting should be considered. With edema reduction, serial splinting may be necessary as ROM is gained to splint toward the ideal position. The sides of the pan should be curved so that they measure approximately inch in height. The curved sides add strength to the pan and ensure that the fingers do not slide radially or ulnarly off the sides of the pan. Splints are used to support an extremity or part of an extremity to align the extremity, allowing function. Functional splints (thermoplastic) and resting splint at night for contracture risk Copely and Kuipers 1999 Eliasson and Burtner 2009 MACS V: Does not handle objects; severely limited ability to perform Diagnostic indication determines the general position used. 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. Full Recovery After Spinal Cord Injury: Is It Possible? The thumb trough supports the thumb and should extend approximately inch beyond the end of the thumb. Figure 9-4 This resting hand splint is fabricated of soft materials and includes a dorsal forearm base design. 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]. Forearm troughs can be volarly or dorsally based. ), Click to share on Twitter (Opens in new window), Click to share on Facebook (Opens in new window), Click to share on Google+ (Opens in new window). Apply knowledge about the application of the resting hand splint (hand immobilization splint) to a case study. Therapists should consider the resting hand splint as a legitimate intervention for appropriate conditions despite the lack of evidence. An advantage of premade splints is their quick application (usually only straps require application). However, individuals with complete spinal cord injuries may not have the same expectations of recovery, but can still benefit from an exercise program to move their upper extremity through full range of motion. Splints on adults should be removed for exercise, hygiene, and appropriate functional tasks. Figure 9-3 This cone splint is often used to help manage tone abnormalities. Figure 9-1 This splint is based on a resting hand splint design and is often used for individuals with rheumatoid arthritis. Therapists can order premolded commercial splints according to hand size (i.e., small, medium, large, and extra large) for the right or left hand. deLinde and Miles [1995] suggested that prefabricated splints may be appropriate for superficial burns with edema for the first three to five days. Rest through immobilization reduces symptoms. The thumb may be positioned midway between radial and palmar abduction to increase comfort. In persons who have RA, the use of splints for purposes of rest during pain and inflammation is controversial [Egan et al. The thumb may or may not be immobilized by the splint. Similar to the resting hand splint design, splints can provide rest to the wrist, thumb, and MCP joints (Figure 9-1). To increase understanding of wearing a hand splint after a spinal cord injury, below is a description of commonly used splints and their purpose. 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 However, typing splints can only be used on a regular computer keyboard. 6Explain the precautions to consider when fabricating a resting hand splint (hand immobilization splint). These joint angles are ideal. The width should be one-half the circumference of the forearm. When a spinal cord injury damages the neural pathways used for communication between the brain and spinal cord, it can impair hand function. FitMi works by encouraging you to practice rehab exercises with high repetition. For full-thickness burns with excessive edema, custom-made splints are necessary [deLinde and Miles 1995]. The volarly based forearm trough at the proximal portion of the splint supports the weight of the forearm. A new logo, messaging & imagery for a hand therapy brand that's been trusted for over 45 years. While many hand splints provide similar benefits, its important to determine the best fit for you. The width should be one-half the circumference. The dorsal skin of the hand will maintain its length in the antideformity position. Dorsally based troughs can be a helpful design for applying a resting hand splint to a person with hypertonicity. Judith Wilton, Hand Splinting: . Describe the antideformity or intrinsic-plus position of the wrist, thumb, and digits. Resting splintsgenerally used to immobilize the joints and provide a prolonged stretch to tight muscles. ), Figure 9-3 This cone splint is often used to help manage tone abnormalities. The resting hand splint may retard further deformity for some persons. . 3Describe the antideformity or intrinsic-plus position of the wrist, thumb, and digits. There are two main types of splint: splints used . Rheumatoid Arthritis 2. [1994] conducted an in-depth literature review to find a standard dorsal hand burn splint design. The phases of recovery are emergent, acute, skin grafting, and rehabilitation. Stages of burn recovery should be considered with splinting. Dorsally based forearm troughs are located on the dorsum of the forearm. Tenodesis splints are worn until the natural movement of tenodesis has been achieved to promote a functional grasp. Forearm troughs can be volarly or dorsally based. The study employed second-year occupational therapy students as splintmakers and first-year occupational therapy students as their clients. The splintmakers also responded to a questionnaire asking about measuring fit, edges, strap application, aesthetics, safety, and ease of positioning. Precuts are interchangeable for right or left extremity application. 2001]. Persons who require resting hand splints commonly have arthritis [Egan et al. deLinde and Miles [1995] suggested that prefabricated splints may be appropriate for superficial burns with edema for the first three to five days. Dorsally based forearm troughs are located on the dorsum of the forearm. The antideformity position for a palmar or circumferential burn places the wrist in 30 to 40 degrees of extension and 0 degrees (i.e., neutral) for a dorsal hand burn. The thermoplastic material was rated safer than the fiberglass material. As with most . With edema reduction, serial splinting may be necessary as ROM is gained to splint toward the ideal position. Hand splints are most effective when combined withtherapeutic exercises for spinal cord injury. Precuts are interchangeable for right or left extremity application. Rolyan's New Look. caused by imbalance between spastic intrinsics and weak extrinsics muscles of the hand. Splints are used to immobilize an extremity or part of an extremity during healing to prevent re-injury and promote correct alignment of the bones and tissues involved. 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. Conversely, Intrinsic Plus Hand is caused due to a muscle imbalance between spastic or tight intrinsics and weak extrinsics. However, if the perforated premolded or precut splint must be trimmed through the perforations a rough edge may result. A resting hand splint with the hand in a functional (mid-joint) position. Therapists must make informed decisions about whether they will fabricate or purchase a splint. The antideformity position is often used to place the hand in such a fashion as to maintain a tension/distraction of anatomic structures to avoid contracture and promote function. Therefore, to improve movement and coordination, survivors must practice high repetition ofhand exercises for spinal cord injury. Long opponens splints helpmaintain web space(area between the thumb and index finger) but are used less frequently than other splints. 2005]; and tenosynovitis [Richard et al. Short opponens splints help maintain thumb web space,prevent hyperextension, and promote functional hand position. The proximal end of the trough should be flared or rolled to avoid a pressure area. Richard et al. Short opponens splints also help facilitate tenodesis by opposing the thumb and preventing it from overstretching when performing tasks. Thus, it is a ripe area for future research. The components of a resting hand splint are the forearm trough, pan, thumb trough, and C bar. Phillips [1995] recommended that persons with acute exacerbations wear splints full-time except for short periods of gentle ROM exercise and hygiene. The intrinsic plus position is otherwise known as the safe position for hand splinting. 2005]; and tenosynovitis [Richard et al. This result decreases the range of motion of the joints in the upper limb. ), Figure 9-2 This resting hand splint positions the hand in an antideformity position for individuals with hand burns. The therapist should closely monitor the person to make necessary adjustments to the splint. (Preformed Anti-Spasticity Hand Splint; courtesy North Coast Medical, Inc., Morgan Hill, California.) 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. Fortunately, wearing proper hand splints after a spinal cord injury can help control and prevent further injury or serious deformities. Chapter Objectives Tags: Introduction to Splinting A Clinical Reasoning and Problem-Solvi Until now, therapists had only one choice. In addition to splint intervention, persons with RA benefit from a combination of management of inflammation, education in joint protection, muscle strengthening, ROM maintenance, and pain reduction [Falconer 1991, Philips 1995]. Some of the commercially sold resting hand splints are prefabricated, premolded, and ready to wear. When splinting a joint with chronic RA, the rationale is often based on biomechanical factors. When fabricating a custom splint for a person with excessive edema, a therapist should avoid forcing wrist and hand joints into the ideal position and risking ischemia from damaged capillaries [deLinde and Miles 1995]. Dorsally based troughs can be a helpful design for applying a resting hand splint to a person with hypertonicity. The yellow and blue pucks track your movement and provide feedback. These joint angles are ideal. Figure 9-9 A resting hand splint with the hand in an antideformity (intrinsic-plus) position. 4List the purposes of a resting hand splint (hand immobilization splint). Typing on a computer can be challenging after a spinal cord injury, but typing hand splints help stabilize finger positions. These joint angles are ideal. Splints can be used for joints affected by arthritis or for other conditions, such as carpal tunnel syndrome. Biese [2002] recommended that persons wear splints at night and part-time during the day. Only gold members can continue reading. Intrinsic Minus Hand is a hand deformity characterized by MCP joint hyperextension with PIP joint and DIP joint flexion caused by an imbalance between strong extrinsics and deficient intrinsics. 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).
