Consistent at-home therapy is key to making this happen. The width should be one-half the circumference of the forearm. Note that wrist extension varies from the typical 30 degrees of extension. 1List diagnoses that benefit from resting hand splints (hand immobilization splints). There are two main types of splint: splints used . Physicians commonly order resting hand splints, also known as hand immobilization splints [American Society of Hand Therapists 1992] or resting pan splints. 1. The level of injury refers to the location along the spinal cord where damage has occurred. Depending on the type of splint, they may recommend wearing it during the day, at night, or for a particular task. Contractures of the intrinsic muscles of the fingers disrupt the delicate and complex balance of the intrinsic and extrinsic muscles. Richard et al. Related ), Figure 9-3 This cone splint is often used to help manage tone abnormalities. 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). Figure 9-2 This resting hand splint positions the hand in an antideformity position for individuals with hand burns. 10Use clinical judgment to evaluate a fabricated resting hand splint (hand immobilization splint). [ 15] Early recognition is essential. Complex regional pain syndrome The proximal end of the trough should be flared or rolled to avoid a pressure area. Intrinsic Plus Splint Surgical Management Excision and grafting Split thickness 0.012in sheet graft -Optimal durability -Function: Reduced Secondary healing -Optimal aesthetics Dorsal: 0.012" Palmar: 0.015-0.018" -Full thickness glabrous if available Split Thickness Graft Full Thickness Skin Graft Local Rotation Flap 2 types of positioning are achieved by a resting hand splint: a functional (mid-joint) position and an antideformity (intrinsic-plus/safe) position. Several diagnostic categories may warrant the provision of a resting hand splint. Some persons with burns may not initially tolerate these joint positions. 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]. 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]. The emergent phase is the first 48 to 72 postburn hours [deLinde and Miles 1995]. Periods of rest (three weeks or less) seem to be beneficial, but longer periods may cause loss of motion [Ouellette 1991]. The thumb may be positioned midway between radial and palmar abduction to increase comfort. Therapists may recommendMCP splintsto block motion in an inflamed joint to help reduce pain. A resting hand splint kit typically contains strapping materials and precut thermoplastic material in the shape of a resting hand splint. The literature cited 43 splints to position the dorsally burned hand joints. 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]. Serial resting hand splints for persons with burns should conform to the person, rather than conforming the person to the splints [deLinde and Miles 1995]. Typing on a computer can be challenging after a spinal cord injury, but typing hand splints help stabilize finger positions. Purpose of the Resting Hand Splint The wrist and forearm should be positioned carefully. The clients responded to a questionnaire addressing comfort, weight, and aesthetics. What is the most likely explanation? When the wrist is in slight extension, the carpal tunnel is openas opposed to being narrowed, with 30 degrees of extension [Melvin 1989]. 2. However, when a spinal cord injury impairs the hands it may affect this natural mechanism. However, it may not additionally prevent deformity [Biese 2002, Falconer 1991]. Static splinting is initiated during the emergent phase to support the hand and maintain the length of vulnerable structures [deLinde and Miles 1995]. The pan of the splint supports the fingers and the palm. 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]. For persons who have hand burns, therapists do not splint in the functional position. Table 9-1 Dorsally based troughs can be a helpful design for applying a resting hand splint to a person with hypertonicity. A resting hand splint is a static splint that immobilizes the fingers and wrist. 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). The forearm trough can be used as a lever to extend the wrist in addition to extending the fingers. Diagnosis is made clinically by observing the resting posture of the hand to assess the digital cascade and the absence of the tenodesis effect. 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]. 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. Stages of burn recovery should be considered with splinting. Your therapist can also provide more guidance on which hand therapy exercises and hand splints are appropriate for you. After a burn injury, the thumb web space is at risk for developing an adduction contracture [Torres-Gray et al. The therapist conforms the pan to the arches of the hand, thus helping to maintain such hand functions as grasping and cupping motions. Several diagnostic categories may warrant the provision of a resting hand splint. Palmar-dorsal splints are designed to be worn regularly for extended periods of time. They also can be positioned to have the wrist bent slightly upwards (wrist extension), allowing individuals to use their hands with assistive devices and perform activities such as eating, typing, and pushing a wheelchair. A splint can be recommended by a physician or a rehabilitation therapist. [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. A disadvantage is that the pattern is not customized to the person. Forearm troughs can be volarly or dorsally based. 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. Periods of rest (three weeks or less) seem to be beneficial, but longer periods may cause loss of motion [, When splinting a joint with chronic RA, the rationale is often based on biomechanical factors. The more you exercise your hands, the higher the chances of improving mobility and overall hand function. List the purposes of a resting hand splint (hand immobilization splint). In addition, persons may find it beneficial to wear splints at night for several weeks after the acute inflammation subsides [Boozer 1993]. If the web space tightens, it inhibits cylindrical grasp and prevents the thumb from fully opposing the other digits. The components of a resting hand splint are the forearm trough, pan, thumb trough, and C bar. Forearm troughs can be volarly or dorsally based. Others are sold as precut resting hand splint kits that include the precut thermoplastic material and strapping mechanism. 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. Wrist/Hand Splint Examples 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. The advantage is an exact fit for the person, which increases the splints support and comfort. Precuts are interchangeable for right or left extremity application. Figure 9-7 Dorsal-based resting hand splint: (A) dorsal view, (B) volar view. Thats why Flint Rehab created FitMi, a motion-sensing, gamified home recovery tool designed for neurological injury like SCI. (OBQ08.238) Persons who require resting hand splints commonly have arthritis [Egan et al. Serial resting hand splints for persons with burns should conform to the person, rather than conforming the person to the splints [deLinde and Miles 1995]. Hand splints help support the integrity of the joints by maintaining their alignment and reducing any potential damage to various connecting structures, such as muscles, tendons, and connective tissues. If these conservative . It provides support to the fingers, hand, and wrist. The proximal interphalangeal (PIP) and distal interphalangeal (DIP) joints are free to move for functional tasks. When inflammation and pain are present in the hand, the joints and surrounding structures become swollen and result in improper hand alignment. However, to accomplish this, hand splints must be molded to fit the arches and creases of an individuals hands. Flexor Tendon Injuries are traumatic injuries to the flexor digitorum superficialis and flexor digitorum profundus tendons that can be caused by laceration or trauma. 2001, Ouellette 1991]; postoperative Dupuytrens contracture release [Prosser and Conolly 1996]; burn injuries to the hand, tendinitis, hemiplegic hand [Pizzi et al. Another disadvantage is that the commercial splint may not exactly fit each person. . 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]. 2001, Ouellette 1991]; postoperative Dupuytrens contracture release [Prosser and Conolly 1996]; burn injuries to the hand, tendinitis, hemiplegic hand [Pizzi et al. Describe the functional or mid-joint position of the wrist, thumb, and digits. 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 therapist has control over joint positioning. If you liked this post, youll LOVE our emails and ebook. There are many other types of splints that may be used to address individual needs - you can discuss these wi th the Spinal Occupational Therapists. When inflammation and pain are present in the hand, the joints and surrounding structures become swollen and result in improper hand alignment.
