resting hand splint vs intrinsic plus
. 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). With premolded splints, the therapist has little control over positioning joints into particular therapeutic angleswhich may be different from the angles already incorporated into the splints design. Anti-deformity (POSI) position i. Functional Position The proximal end of the trough should be flared or rolled to avoid a pressure area. Similar to the resting hand splint design, splints can provide rest to the wrist, thumb, and MCP joints (Figure 9-1). When a great amount of forearm support is desired, a volarly based forearm trough is the best design (Figure 9-6). Determine a resting hand (hand immobilization) splint-wearing schedule for different diagnostic indications. When the wrist is in slight extension, the carpal tunnel is openas opposed to being narrowed, with 30 degrees of extension [Melvin 1989]. 1List diagnoses that benefit from resting hand splints (hand immobilization splints). Copyright 2023 Lineage Medical, Inc. All rights reserved. Design to optimally position the hand in an intrinsic-plus position after a burn injury. Figure 9-9 A resting hand splint with the hand in an antideformity (intrinsic-plus) position. These joint angles are ideal. Below we have listed the most effective and commonly prescribed by therapists. SoftPro Functional Resting Hand Splint treats moderate flexion contractures of wrist/hand/thumb. When the wrist is in slight extension, the carpal tunnel is openas opposed to being narrowed, with 30 degrees of extension [Melvin 1989]. For persons who have hand burns, therapists do not splint in the functional position. The degree to which a persons compliance with a splint-wearing schedule affects the disease outcome is unknown. Figure 9-1 This splint is based on a resting hand splint design and is often used for individuals with rheumatoid arthritis. Therapists fabricate custom resting hand splints or purchase them commercially. ), Figure 9-4 This resting hand splint is fabricated of soft materials and includes a dorsal forearm base design. 2005]; and tenosynovitis [Richard et al. The best hand splints for spinal cord injury include: 1. Several diagnostic categories may warrant the provision of a resting hand splint. Individuals with an intrinsic plus hand will demonstrate difficulty gripping large objects. 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 On physical exam, he can passively flex the proximal interphalangeal (PIP) joint when the metacarpophalangeal (MCP) joint is flexed but not when the MCP joint is extended. (OBQ18.120) summary. Depending on the type of splint, they may recommend wearing it during the day, at night, or for a particular task. Richard et al. Undo all Velcro straps on the splint and place in front of the patient's weak arm. Consult with your therapist to see what hand splints after spinal cord injury are most suitable for your needs and overall goals. Therapists must make informed decisions about whether they will fabricate or purchase a splint. The width should be one-half the circumference. 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]. The thumb may be positioned midway between radial and palmar abduction to increase comfort. 3Describe the antideformity or intrinsic-plus position of the wrist, thumb, and digits. A splint is an orthotic device that can be used to protect, support, immobilize or position an injured hand. A spinal cord injury can impair various bodily functions, including the ability to use your hands. 2005]. Therapists can order premolded commercial splints according to hand size (i.e., small, medium, large, and extra large) for the right or left hand. The splints must be ordered for application on the right or left extremity, whereas the precut splint is universal for the right or left hand. An advantage of using a kit is the time the therapist saves by elimination of pattern making and cutting of thermoplastic material. A prefabricated resting hand splint in an antideformity position can be applied if a therapist cannot immediately construct a custom-made splint [deLinde and Miles 1995]. 1994]. A resting hand splint positioning the hand in a functional position is also advocated for spasticity (Figure 9-4). Sometimes it is called intrinsic plus hand. After a spinal cord injury, the upper extremities may become weak or paralyzed, specifically with regard to the hands. [1994] conducted an in-depth literature review to find a standard dorsal hand burn splint design. A resting hand splint with the hand in an antideformity (intrinsic-plus) position. These hand splints are usually worn at night through an alternating schedule. 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 [. The primary goal of a wrist splint is toprevent overstretching of the wristextensor muscles and provide a stable base of support for completing tasks. 2001]. An advantage of using a kit is the time the therapist saves by elimination of pattern making and cutting of thermoplastic material. Similar to premolded splints, precuts from perforated materials contain perforations in only the body of the splint. To rest the wrist and hand joints, the resting hand splint positions the hand in a functional or mid-joint position [Colditz 1995] (Figure 9-8). In persons who have RA, the use of splints for purposes of rest during pain and inflammation is controversial [Egan et al. Several diagnostic categories may warrant the provision of a resting hand splint. Additional splint data collected in 1994 from 46 international SCI rehabilitation centers indicates, resting hand splints were prescribed to promote functional positioning, maintain joint . Describe the antideformity or intrinsic-plus position of the wrist, thumb, and digits. 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. Shop our selection of braces, splinting materials, and hand strengthening devices today. This result decreases the range of motion of the joints in the upper limb. Splinting can be a helpful treatment technique for spinal cord injury survivors that experience residual difficulty with hand function. The volarly based forearm trough at the proximal portion of the splint supports the weight of the forearm. 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 (. 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. 5Identify the components of a resting hand splint (hand immobilization splint). Related 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]. 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 [Falconer 1991]. Therapists fabricate custom resting hand splints or purchase them commercially. Figure 9-3 This cone splint is often used to help manage tone abnormalities. Rest through immobilization reduces symptoms. Individuals who experience a spinal cord injury can usually remove these splints using their teeth, making them easier to remove without assistance. 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. 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). The more the central nervous system is stimulated, the more neuroplasticity can create and strengthen neural pathways needed to restore hand function. Physicians commonly order resting hand splints, also known as hand immobilization splints [American Society of Hand Therapists 1992] or resting pan splints. Based on the nature of the spinal cord injury, incomplete injuries can expect to make improvement of hand motion and strength. Complex regional pain syndrome For children, splints are removed for exercise, hygiene, and play activities [deLinde and Miles 1995]. 9Apply knowledge about the application of the resting hand splint (hand immobilization splint) to a case study. Contractures of the intrinsic muscles of the fingers disrupt the delicate and complex balance of the intrinsic and extrinsic muscles. These structures are the collateral ligaments of the MCPs, the volar plates of the IPs, and the wrist capsule and ligaments. Extensor Tendon Injuries are traumatic injuries to the extensor tendons that can be caused by laceration, trauma, or overuse. 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. Some of the commercially sold resting hand splints are prefabricated, premolded, and ready to wear. 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]. 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. Finger spacers may be used in the pan to provide comfort and to prevent finger slippage in the splint [Melvin 1989]. Log In or Register to continue This extension allows the entire thumb to rest in the trough. A resting hand splint is a static splint that immobilizes the fingers and wrist. 1994]. They are tailored to help individuals who have proper wrist extension but an imbalance between the extrinsic and intrinsic finger muscles. 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. The emergent phase is the first 48 to 72 postburn hours [deLinde and Miles 1995]. Although hand immobilization splints are commonly used, a paucity of literature exists on their efficacy. A disadvantage is that customization may require more of the therapists time to complete the splint and may be more costly. Treatment may be nonoperative or operative depending on the severity of the contracture and impact on quality of life. 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 (Figure 9-3). This can include more specific splints such as elbow extension splints, elbow pillow splints, anti-spasticity splints, and intrinsic plus or minus splints. 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 . 2 types of positioning are achieved by a resting hand splint: a functional (mid-joint) position and an antideformity (intrinsic-plus/safe) position. The emergent phase is the first 48 to 72 postburn hours [deLinde and Miles 1995]. 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]. For example, damage to the spinal cord can result in paralysis or immobility, depending on the severity andlevel of injury. When splinting a joint with chronic RA, the rationale is often based on biomechanical factors. Your therapist can also provide more guidance on which hand therapy exercises and hand splints are appropriate 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.

For persons who have hand burns, therapists do not splint in the functional position. Positioning to counteract the forces of edema includes placing the wrist in 15 to 20 degrees of extension, the MCP joints in 60 to 70 degrees of flexion, and the PIP and DIP joints in full extension, with the thumb positioned midway between palmar and radial abduction and with the IP joint slightly flexed [deLinde and Miles 1995]. The literature cited 43 splints to position the dorsally burned hand joints. 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. Emergent Phase The dorsal skin of the hand will maintain its length in the antideformity position. FitMi works by encouraging you to practice rehab exercises with high repetition. . 2Describe the functional or mid-joint position of the wrist, thumb, and digits. During this time frame, dorsal edema occurs and encourages wrist flexion, MCP joint hyperextension, and IP joint flexion [deLinde and Miles 1995]. Resting Hand Splint Positioning There is an advantage to ordering a premolded resting hand splint made from perforated material. While many hand splints provide similar benefits, its important to determine the best fit for you. [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. 8Describe splint-cleaning techniques that address infection control. The proximal interphalangeal (PIP) and distal interphalangeal (DIP) joints are free to move for functional tasks. After a burn injury, the thumb web space is at risk for developing an adduction contracture [Torres-Gray et al. 6Explain the precautions to consider when fabricating a resting hand splint (hand immobilization splint). There is an advantage to ordering a premolded resting hand splint made from perforated material. Positioning may vary, depending on the surface of the hand that is burned. Existing neural pathways can be strengthened and new ones created with the help ofneuroplasticity, the central nervous systems ability to repair itself. If left unmanaged, further complications can develop which decrease overall ability to return to a prior level of function. A new radiograph is shown in figure A. These joint angles are ideal. 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. 4List the purposes of a resting hand splint (hand immobilization splint). The therapist may provide a splint for a person with arthritis who has early signs of ulnar drift by placing the hand in a comfor table neutral position with the joints in mid-position. The therapist conforms the pan to the arches of the hand, thus helping to maintain such hand functions as grasping and cupping motions. The degree to which a persons compliance with a splint-wearing schedule affects the disease outcome is unknown. Young children who have burned hands may not need splints because the bulky dressings applied to the burned hand may provide adequate support. 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. 2. 2001. Extra long wrist strap maintains proper position while applying gentle . Thats why Flint Rehab created FitMi, a motion-sensing, gamified home recovery tool designed for neurological injury like SCI. Judith Wilton, Hand Splinting: . When the wrist is bent upwards (extended), the fingers curl up together and form a grip. Second-year occupational therapy students chosen as splint makers answered a questionnaire measuring fit, edges, strap application, aesthetics, safety, and ease of positioning. Describe splint-cleaning techniques that address infection control. Lastly, there are other hand splints for spinal cord injury that are commonly prescribed by therapists depending on the needs of every individual. Therapists use clinical judgment to determine what joint angles are positions of comfort for splinting. deLinde and Miles [1995] suggested that prefabricated splints may be appropriate for superficial burns with edema for the first three to five days. Only gold members can continue reading. An advantage of premade splints is their quick application (usually only straps require application). Short opponens splints also help facilitate tenodesis by opposing the thumb and preventing it from overstretching when performing tasks. However, neuroplasticity is best activated with high repetition of exercises, ormassed practice. caused by imbalance between spastic intrinsics and weak extrinsics muscles of the hand. Youll also receive our popular recovery emails with SCI survivor stories and other useful tips you can opt out anytime. Others are sold as precut resting hand splint kits that include the precut thermoplastic material and strapping mechanism. I believe this device will help me concentrate on making the repetitive actions needed to obtain further movement range in my wrist and hand and arm and therefore rating it with five stars. A 39-year-old construction worker presents to your clinic with a complaint of decreased ability to use his right hand at work. 1990]. For dorsal surface hand burns, the splint should position the hand in the angle of antideformity, also referred to as intrinsic plus position. After a burn injury, the thumb web space is at risk for developing an adduction contracture [Torres-Gray et al.
