CHAPTER 9 Similar to the resting hand splint design, splints can provide rest to the wrist, thumb, and MCP joints (Figure 9-1). When tolerable, the resting hand splint for the person who has hand burns can be adjusted more closely to the ideal position. A disadvantage is that the pattern is not customized to the person. 1994]. Resting Hand Splint wrist at 20-30 deg ext, thumb at 45 deg palmer abd, MCPs at 35-45 deg flex, and PIPs/DIPs in slight flex; RA, Crush injuries, burns, spasticity due to upper motor neuron lesions, flaccidity Hand based finger splint for immobilizing MCP in extension with IP joint free trigger finger Cock-Up Splint For persons who have hand burns, therapists do not splint in the functional position. Antideformity position 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]. The initial splint provision for a person with hand burns should be applied with gauze rather than straps. Persons with hand burns have bandages covering burn sites. 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]. The more the central nervous system is stimulated, the more neuroplasticity can create and strengthen neural pathways needed to restore hand function. When a great amount of forearm support is desired, a volarly based forearm trough is the best design (Figure 9-6). List diagnoses that benefit from resting hand splints (hand immobilization splints). 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). Diagnostic Indications THERAPEUTIC OBJECTIVE However, it may prevent further deformity. However, to accomplish this, hand splints must be molded to fit the arches and creases of an individuals hands. The therapist has control over joint positioning. The C bar keeps the web space of the thumb positioned in palmar abduction. In persons who have RA, the use of splints for purposes of rest during pain and inflammation is controversial [Egan et al. Clinicians customize splint position based on muscle tone, ability to perform a functional grasp, and remaining active finger motion. Diagnosis is made clinically by physical examination and performing various provocative tests depending on the location of the injury. Tenodesis splints are designed to help tighten the soft tissues of the hands that become loose when the muscles are not working properly. Wrist/Hand Splint Examples Limb elevation is crucial, and care must be taken to avoid applying compressive dressings such as Ace wraps or restrictive circular casts. After a burn injury, the thumb web space is at risk for developing an adduction contracture [Torres-Gray et al. Periods of rest (three weeks or less) seem to be beneficial, but longer periods may cause loss of motion [Ouellette 1991]. Complex regional pain syndrome 2001]. 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]. Therapists should consider the resting hand splint as a legitimate intervention for appropriate conditions despite the lack of evidence. Splints are available in different sizes for the right and left hands. A 45-year-old carpenter complains of difficult gripping a hammer, which worsens with repeated use. Similar to premolded splints, precuts from perforated materials contain perforations in only the body of the splint. 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. 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]. 2001, Ouellette 1991]; postoperative Dupuytrens contracture release [Prosser and Conolly 1996]; burn injuries to the hand, tendinitis, hemiplegic hand [Pizzi et al. Persons who require resting hand splints commonly have arthritis [Egan et al. Note that wrist extension varies from the typical 30 degrees of extension. A splint can be recommended by a physician or a rehabilitation therapist. The dorsal skin of the hand will maintain its length in the antideformity position. Twenty-six of these splints were labeled as antideformity splints and 17 were identified as having a position of function. This can reduce the amount . The thumb may or may not be immobilized by the splint. The width should be one-half the circumference of the forearm. Figure 9-9 A resting hand splint with the hand in an antideformity (intrinsic-plus) position. Youll also receive our popular recovery emails with SCI survivor stories and other useful tips you can opt out anytime. These splints helpstabilize the fingerswhile allowing the tips to be used, such as for touch screen smartphones or tablets. 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. While you can achieve massed practice with a written sheet of exercises, it can be tough to stick with it consistently and consistency is key to recovery. 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 therapist should closely monitor the person to make necessary adjustments to the splint. This extension allows the entire thumb to rest in the trough. For children, splints are removed for exercise, hygiene, and play activities [deLinde and Miles 1995]. Hand Therapy and Splinting. Conversely, Intrinsic Plus Hand is caused due to a muscle imbalance between spastic or tight intrinsics and weak extrinsics. 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 (Figure 9-7). 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. What to Expect When Caring For an Individual with Quadriplegia at Home. Stages of burn recovery should be considered with splinting. Joints that are receptive to proper positioning may allow for optimal maintenance of range of motion (ROM) [Ziegler 1984]. Brenda M. Coppard, PhD, OTR/L The premolded splint has perforations only in the body of the splint. Phillips [1995] recommended that persons with acute exacerbations wear splints full-time except for short periods of gentle ROM exercise and hygiene. [1994] conducted an in-depth literature review to find a standard dorsal hand burn splint design. Therefore, to improve movement and coordination, survivors must practice high repetition ofhand exercises for spinal cord injury. 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]. Flexor Tendon Injuries are traumatic injuries to the flexor digitorum superficialis and flexor digitorum profundus tendons that can be caused by laceration or trauma. 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]. (Progress Dorsal Anti-Spasticity splint; courtesy North Coast Medical, Inc., Morgan Hill, California.) 1994]. A 39-year-old construction worker presents to your clinic with a complaint of decreased ability to use his right hand at work. Massed practice like this helps stimulate and rewire the nervous system. After a spinal cord injury, the upper extremities may become weak or paralyzed, specifically with regard to the hands. Additional splint data collected in 1994 from 46 international SCI rehabilitation centers indicates, resting hand splints were prescribed to promote functional positioning, maintain joint . Splints are important in the management of a burned hand, and the type of splint used depends on the location of the burn and the anticipated deformity. Richard et al. These structures are the collateral ligaments of the MCPs, the volar plates of the IPs, and the wrist capsule and ligaments. of the forearm. They help redirect, isolate, and increase active motion in weak or stiff joints. However, therapists may recommend them for specific functional activities while also reminding survivors to be mindful when using long opponens because they can interfere with wheelchair operation. If you liked this post, youll LOVE our emails and ebook. 1994]. . 2001]. 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 pan of the splint supports the fingers and the palm. 1990]. Splints or half-casts can also be custom-made, especially if an exact fit is necessary. Extensor Tendon Injuries are traumatic injuries to the extensor tendons that can be caused by laceration, trauma, or overuse. The thumb may or may not be immobilized by the splint. Typing on a computer can be challenging after a spinal cord injury, but typing hand splints help stabilize finger positions. Its really a great device that minutely takes care of each and every muscle of your affected body part. You can rate this topic again in 12 months. Static splinting is initiated during the emergent phase to support the hand and maintain the length of vulnerable structures [deLinde and Miles 1995]. If a child is age three or older, splinting should be considered. 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). However, if the pans edges are too high the positioning strap bridges over the fingers and fails to anchor them properly. When the wrist is in slight extension, the carpal tunnel is openas opposed to being narrowed, with 30 degrees of extension [Melvin 1989].

Instead, the therapist places the hand in the intrinsic-plus or antideformity position (seeFigure 9-9). This cone splint is often used to help manage tone abnormalities. Young children who have burned hands may not need splints because the bulky dressings applied to the burned hand may provide adequate support. For full-thickness burns with excessive edema, custom-made splints are necessary [deLinde and Miles 1995]. Figure 9-7 Dorsal-based resting hand splint: (A) dorsal view, (B) volar view. Figure 9-5 The components of a resting hand splint are the forearm trough, pan, thumb trough, and C bar. 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, Compliance of persons with RA in wearing resting hand splints has been estimated at approximately 50%, [Feinberg 1992]. For children with dorsal hand burns, during the emergent phase the MCP joints may not need to be flexed as far as 60 to 70 degrees. 1996]. Therefore, palmar abduction of the thumb is the position of choice for the thumb CMC joint. Diagnostic indication determines the general position used. The level of injury refers to the location along the spinal cord where damage has occurred. 2. Diagnosis is made clinically by observing the resting posture of the hand to assess the digital cascade and the absence of the tenodesis effect. Therapists should consider the resting hand splint as a legitimate intervention for appropriate conditions despite the lack of evidence. 4List the purposes of a resting hand splint (hand immobilization splint). When the wrist is in slight extension, the carpal tunnel is openas opposed to being narrowed, with 30 degrees of extension [Melvin 1989]. During this time frame, dorsal edema occurs and encourages wrist flexion, MCP joint hyperextension, and IP joint flexion [deLinde and Miles 1995]. The resting hand splint has three purposes: to immobilize, to position in functional alignment, and to retard further deformity [Malick 1972. Customized Splints 2005]; and tenosynovitis [Richard et al. Physicians commonly order resting hand splints, also known as hand immobilization splints [American Society of Hand Therapists 1992] or resting pan splints. These joint angles are ideal. Similar to premolded splints, precuts from perforated materials contain perforations in only the body of the splint. Therapists fabricate custom resting hand splints or purchase them commercially. Palmar surface burns should be positioned in . Biese [2002] recommended that persons wear splints at night and part-time during the day. If these conservative . 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. 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 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. . Because of the small sample, these results should be cautiously interpretedand further studies are warranted. Thus, a wide range of designs exists for splinting dorsal hand burns [Richard et al. Figure 9-5 The components of a resting hand splint are the forearm trough, pan, thumb trough, and C bar. 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). 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. 2Describe the functional or mid-joint position of the wrist, thumb, and digits. [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. These joint angles are ideal. The premolded splint has perforations only in the body of the splint. Stages of burn recovery should be considered with splinting. Carius BM, Canine CR, Long B. Intrinsic plus hand: Painful Finger flexion and extension . 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]. 2001]. However, it may not additionally prevent deformity [Biese 2002, Falconer 1991]. There are two main types of splint: splints used . 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. The intrinsic plus position is otherwise known as the safe position for hand splinting. Home Neurological Recovery Blog Spinal Cord Injury Hand Splints for Spinal Cord Injury: How to Choose the Right Fit for You. Design to optimally position the hand in an intrinsic-plus position after a burn injury. These off-the-shelf splints are made in a variety of shapes and sizes and are much easier and faster to use. Twenty-six of these splints were labeled as antideformity splints and 17 were identified as having a position of function. A resting hand splint is a static splint that immobilizes the fingers and wrist. Kits are available according to hand size (i.e., small, medium, large, and extra large). This reduces the risk of compromising circulation. Splinting can be a helpful treatment technique for spinal cord injury survivors that experience residual difficulty with hand function. 1996]. SoftPro Functional Resting Hand Splint treats moderate flexion contractures of wrist/hand/thumb. 1990]. 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]. 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. The degree to which a persons compliance with a splint-wearing schedule affects the disease outcome is unknown. Long opponens splints helpmaintain web space(area between the thumb and index finger) but are used less frequently than other splints. 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]. Similar to the resting hand splint design, splints can provide rest to the wrist, thumb, and MCP joints (. Biese [2002] recommended that persons wear splints at night and part-time during the day. The therapist also has control over joint positioning. 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. However after trying FitMi, I could feel that slowly and steadily I am improving. 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].
