resting hand splint vs intrinsic plus
Note that wrist extension varies from the typical 30 degrees of extension. The biomechanical rationale for splinting acutely inflamed joints is to reduce pain by relieving stress and muscle spasms. 2. Perforations at the edges of splints are undesirable because of the discomfort they often create. 2001, Ouellette 1991]; postoperative Dupuytrens contracture release [Prosser and Conolly 1996]; burn injuries to the hand, tendinitis, hemiplegic hand [Pizzi et al. A disadvantage is that customization may require more of the therapists time to complete the splint and may be more costly. These joint angles are ideal. Splints can either bedynamic, meaning they allow movement, or they can bestaticwhich means they are in a fixed position. Diagnosis is made clinically by observing the resting posture of the hand to assess the digital cascade and the absence of the tenodesis effect. Therefore, the precut splint may require many adjustments to obtain a proper fit. During this time frame, dorsal edema occurs and encourages wrist flexion, MCP joint hyperextension, and IP joint flexion [. 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. 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 (. Short opponens splints help maintain thumb web space,prevent hyperextension, and promote functional hand position. The resting hand splint has three purposes: to immobilize, to position in functional alignment, and to retard further deformity [Malick 1972, Ziegler 1984]. 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. 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 My occupational therapist recommended to give this a try. Before reviewing the list, lets take a look at the benefits of using hand splints to treat a spinal cord injury and the process of determining the best splint option. The therapist also has control over joint positioning. 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). This is why when a hand or wrist is being casted or splinted, care is taken to put it in the position that will minimize stiffness. For persons who have hand burns, therapists do not splint in the functional position. Figure 9-7 Dorsal-based resting hand splint: (A) dorsal view, (B) volar view. The more the central nervous system is stimulated, the more neuroplasticity can create and strengthen neural pathways needed to restore hand function. 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. Therapists use clinical judgment to determine what joint angles are positions of comfort for splinting. Resting splint the shape you've trusted and the comfort that just isn't possible with hard plastics. 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]. Therapists must make informed decisions about whether they will fabricate or purchase a splint. Typing splints are designed to help survivors use a keyboard. Tenodesis splints are worn until the natural movement of tenodesis has been achieved to promote a functional grasp. Metacarpal-phalangeal blocking (MCP) splints help to promote proper motion of the finger during functional hand tasks. Antideformity position Four main components comprise the resting hand splint: the forearm trough, the pan, the thumb trough, and the C bar (Figure 9-5) [Fess et al. 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]. Therefore, the precut splint may require many adjustments to obtain a proper fit. Hand and wrist splints are designed to protect and support painful, swollen or weak joints and their surrounding structures by making sure your hand and wrist are positioned correctly. 2005]. However, to accomplish this, hand splints must be molded to fit the arches and creases of an individuals hands. SoftPro Functional Resting Hand Splint treats moderate flexion contractures of wrist/hand/thumb. 10Use clinical judgment to evaluate a fabricated resting hand splint (hand immobilization splint). After a burn injury, the thumb web space is at risk for developing an adduction contracture [Torres-Gray et al. 1994]. Resting Hand Splints. When inflammation and pain are present in the hand, the joints and surrounding structures become swollen and result in improper hand alignment. Therapists often provide resting hand splints for people with rheumatoid arthritis (RA) during periods of acute inflammation and pain [Biese 2002, Ziegler 1984] and when these people do not use their hands for activities but require support and immobilization [Leonard 1990]. When tolerable, the resting hand splint for the person who has hand burns can be adjusted more closely to the ideal position. A splint applied in the first 72 hours after a burn may not fit the person 2 hours after application because of the significant edema that usually follows a burn injury. Perforations at the edges of splints are undesirable because of the discomfort they often create. The therapist has control over joint positioning. Youll also receive our popular recovery emails with SCI survivor stories and other useful tips you can opt out anytime. The therapist should closely monitor the person to make necessary adjustments to the splint. Conversely, Intrinsic Plus Hand is caused due to a muscle imbalance between spastic or tight intrinsics and weak extrinsics. 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]. Existing neural pathways can be strengthened and new ones created with the help ofneuroplasticity, the central nervous systems ability to repair itself. [1994] conducted an in-depth literature review to find a standard dorsal hand burn splint design. The thumb trough supports the thumb and should extend approximately inch beyond the end of the thumb. This extension allows the entire thumb to rest in the trough. The thumb web space is also vulnerable to remodeling in a shortened form in the presence of inflammation and in a situation in which tension of the structure is absent. The resting hand splint may retard further deformity for some persons. The primary goal of a wrist splint is toprevent overstretching of the wristextensor muscles and provide a stable base of support for completing tasks. The yellow and blue pucks track your movement and provide feedback. Therapists fabricate custom resting hand splints or purchase them commercially. Forearm troughs can be volarly or dorsally based. However, it may prevent further deformity. With an understanding that splinting is most effective with a customized exercise program, please consult with your therapist to determine which splint option is right for you. deLinde and Knothe [2002] suggested that for children under the age of three therapists may not need to splint unless it is determined that the wrist requires support. Related This extension allows the entire thumb to rest in the trough. Kits are available according to hand size (i.e., small, medium, large, and extra large). According to Falconer [1991, p. 83], Theoretically, by realigning and redistributing the damaging internal and external forces acting on the joint, the splint may help to prevent deformity __or improve joint function and functional use of the extremity. Therapists who splint persons with chronic RA should be aware that prolonged use of a resting hand splint may also be harmful [. Prevent contractures during healing following burn or other injuries. In persons who have RA, the use of splints for purposes of rest during pain and inflammation is controversial [Egan et al. (OBQ08.238) When a spinal cord injury damages the neural pathways used for communication between the brain and spinal cord, it can impair hand function. 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). Describe splint-cleaning techniques that address infection control. After a spinal cord injury, the fingers and/or wrist may increase in tone as a result of the neurological damage. Initially I wasnt sure if it would work because of the various treatments I tried and also many physiotherapists who tried their level best, but didnt achieve any positive results. FitMi helps transform rehab exercises into an engaging, interactive experience. 1996]. A resting hand splint with the hand in an antideformity (intrinsic-plus) position. 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. 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. Finger spacers may be used in the pan to provide comfort and to prevent finger slippage in the splint [Melvin 1989]. Some have Velcro straps which make the splints easy to put on, take off, and adjust. There are a variety of hand splints that can be used to treat individuals with spinal cord injuries. The sides of the pan should be curved so that they measure approximately inch in height. The thermoplastic material was rated safer than the fiberglass material. A resting hand splint positioning the hand in a functional position is also advocated for spasticity (Figure 9-4). Some of the commercially sold resting hand splints are prefabricated, premolded, and ready to wear.Table 9-1 outlines prefabricated splints for the wrist and hand. According to Richard et al. Forearm troughs can be volarly or dorsally based. This will maintain joint integrity, decrease joint stiffness, and help to prevent pain or discomfort from immobility. A disadvantage is that customization may require more of the therapists time to complete the splint and may be more costly. Precuts are interchangeable for right or left extremity application. Figure 9-9 A resting hand splint with the hand in an antideformity (intrinsic-plus) position. 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]. When the wrist is in slight extension, the carpal tunnel is openas opposed to being narrowed, with 30 degrees of extension [Melvin 1989]. These joint angles are ideal. 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]. Persons with hand burns have bandages covering burn sites. Resting hand orthosis is usually fabricated in one of two positions: Functional position Anti-deformity/intrinsic-plus/safe position Functional Position of resting hand splint Wrist: 20-30 degrees extension Thumb: 45 degrees palmar abduction MP joints: 35-45 degrees flexion PIP & DIPs: slight flexion Functional position of hand As with most . AliLite Splints are the only prefitted splints made of featherweight AliLite. Similar to premolded splints, precuts from perforated materials contain perforations in only the body of the splint. Some of the commercially sold resting hand splints are prefabricated, premolded, and ready to wear. Share this: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) Place the forearm in the large trough. The edges are smooth because there are no perforations near the edges of the splint. In addition, persons may find it beneficial to wear splints at night for several weeks after the acute inflammation subsides [Boozer 1993]. The thumb may or may not be immobilized by the splint. Treatment may be nonoperative or operative depending on the severity of the contracture and impact on quality of life. The thumb may or may not be immobilized by the splint. Hand Immobilization Splints Splints are used to support an extremity or part of an extremity to align the extremity, allowing function. A resting hand splint with the hand in a functional (mid-joint) position. 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].
