Introduction
Burn care or burn rehabilitation at any level or phase of recovery can be very overwhelming to the non-burn spe­cialist. In this chapter, we aim to provide education and practical approaches to burn rehabilitation for the non­burn specialist. With all of the significant advances in medi­cal care for the patients that have suffered a burn injury over the past few decades, the survival rates of patients

with large total body surface area (TBSA) burn have greatly increased. There is evidence to support early involvement of occupational therapy (OT), physical ther­apy (PT), and exercise training in helping burn survivors reach their best possible outcome and continue to lead a meaningful and productive life. Implementing a rehabilita­tion program as soon as a patient is medically stable is imperative. This applies to a patient who has suffered a large burn and is being treated in a burn unit or to a patient who has suffered a small burn and is being treated in an outpatient setting. This chapter focuses on rehabilitation including OT and PT for the burn patients.
In rehabilitation of the burn patient, the lines between OT and PT can become blurred. The occupational therapist (OTs) and physical therapist (PTs) work as burn rehabilita­tion therapists. Each discipline has their specific roles and goals, however, burn therapy as a collective has many com­mon threads. For example, goals of rehabilitation include prevention of contractures, preserving or regaining range of motion (ROM), strength, and functional abilities as well as helping patients to return to independent living. Although this is not a complete and exhaustive list, these are a few of the common threads for both OTs and PTs.
Role ofOT inCare oftheBurn Patient
OT theory is based on the belief that rehabilitation of dysfunction can occur through the use of occupations (daily activities and tasks) that have meaning for a patient. OTs assist the burn patient in engaging in and recovering the ability to perform Activities of Daily Living (ADLs)/ Instrumental Activities of Daily Living (IADLs), vocational and avocational activities, to help them return to their life roles as soon as possible. In burn care, OTs will screen or assess for potential for contractures, possible effects of scar, loss of skill performances, as well as evaluating for loss of motion, strength, edema, sensory injury or issues, cognition,

and psychological adjustment. One of the major roles for an OT is determining the need for orthoses, positioning devices, adaptive or assistive equipment, and pressure garments. Once the screen or evaluation is complete, the OTs will establish a treatment plan. The OTs will inform and collabo­rate with the burn team on their plan of care. Initiation of OT should begin within 24 h of a patient being admitted after burn injury. OT will continue through the acute care phase, as well as during an acute rehabilitation stay, and in an outpatient setting. OT and /or PT should also be part of an outpatient burn clinic and care should be initiated as soon as possible to help achieve the best possible outcomes. Function, scar, and cosmesis will be the initial goals of treat­ment at this stage. A key point will be communication between all identified health care team.

Role ofPT inCare oftheBurn Patient
PTs plays a critical role in the multidisciplinary care of a patient who has sustained burns. Burns cause multisystem medical problems causing potential for prolonged hospital­izations and lengthy recovery. In the acute phase of care for hospitalized patients, PT should be initiated as early as the first 24 h. PTs primary goals are to limit loss of ROM, reduce edema, prevent predictable contractures through positioning and splinting, and prepare the patient for dis­charge by addressing patient function. Care for the patient will continue through rehabilitation stays and home care. The primary PT goals remain the same with the addition of assisting with initial scar management through early com­pression. The PTs may also assist with helping the patient adapt to any psychosocial issues related to their burn. Some key concepts to consider with acute treatment of patients with burns are maintaining effective communication with the team, scheduling therapy sessions around pain medica­tion distribution, as well as patient and family education. As the patient progresses, outpatient services are often

warranted and should be initiated as soon as possible upon the patient returning home. The outpatient PTs must con­tinue to address any continued problem areas with ROM and edema but also progress the patient’s strength and endurance through resistive exercise and cardiovascular exercise. The PTs should also address function as it pertains to return to work and any ADL. Special education should be provided on pressure garments, and scar management, and communication with the burn team should be ongoing to provide input on any skin contractures that may need reconstructive surgery.
Acute Rehabilitation ofaBurn Injury
After a burn patient has been admitted to a hospital and has been stabilized medically, referrals for OT and PT should be placed. OT and PT begin in the acute care stage of burn patients and continue throughout the entire reha­bilitation process. These along with familiar components of rehabilitation including evaluation, assessment of ROM, strength, sensation, edema, mobility, and ADLs are para­mount to a successful initiation and plan for rehabilitation. Adaptive equipment or devices may also be used in the acute phase of treatment, and of significant importance to the progress and success in this acute stage will be position­ing and orthoses. Psychological adjustment is also impor­tant to consider when treating a person who has suffered a burn injury. Even with small burns, it can have an effect psychologically and socially. These psychosocial effects should be monitored throughout the rehabilitation process, discussed, and addressed with the entire team as needed. During this acute rehabilitation stage, pain can be a limiting factor in a patient’s participation in activities and exercise. Along with being aware of medication regimens, patient education regarding coping techniques should also be initi­ated early.

Positioning andOrthoses
Positioning
Throughout a patient’s recovery, with significant emphasis in the acute phase of hospitalization, attention to positioning and prevention of contractures should be near the top of the prior­ity after medical stability. Preventing or correcting contrac­tures is integral in helping a burn patient return to function. Positioning a patient is all health care team’s responsibility, however a rehabilitation therapist, OT, and/or PT may lead the way in determination of positioning for the best possible effect on functional performance and mitigation of possible contractures. Communication throughout the team regarding positioning will need to take place regularly. Pictures placed in the medical record or in the patient’s room along with in per­son education for the staff and families are also a good way to ensure proper positioning. Also, if a patient is able in the acute stage, reinforcement of proper positioning verbally and with visual aids with the patient will begin to allow the patient to engage in their recovery process.
Keys to remember in a positioning program include reducing edema, reducing risk of contractures, allowing proper joint alignment, allowing facilitation of wound care, and reducing risk of possible associated iatrogenic injuries such as peripheral neuropathy and pressure sores.
There are several ways to achieve a proper antideformity positioning and neutral postures as well as protection of bony prominences. Orthoses, serial casting, foam-based troughs, wedges, pillows, straps and at times surgical intervention with pins or traction may be utilized to achieve a positioning goal.
Awareness and knowledge of contracture predisposition are important to understand for positioning and splinting purposes. Below is a table of some of the most common con­tracture predispositions and their splinting or orthotic recom­mendations (Table21.1).

Orthoses
The overarching goal of splinting is to assist in reaching the best functional outcome. The use of orthoses or casting can help to prevent loss of motion, preserve or improve ROM, protect vulnerable structures (skin grafts), assist in scar man­agement and correction of contractures, support and/or assist weakened muscles as well as support, protect, and immobilize affected joints. Care should be taken so that an orthosis can allow for a reduction of edema, promotion of wound healing and maintenance of proper joint alignment. Care should also be taken that an orthosis does not cause harm in the form of pain, improper application over pressure points, and shearing of tissue or new skin grafts. An orthosis should be designed with forethought of function and ease of application and removal for dressing changes and/or exercise and function. In the acute hospital or rehabilitation stay, education for the health care team, family members and patients will be imper­ative to achieving the overall outcome for the use of an orthosis. In person demonstration of application/removal and proper positioning is vital, and adjunct education in the form of pictures or even videos in the patient’s EMR, pictures hanging on the walls of the patient’s room will assist in mak­ing sure an orthosis is utilized correctly for maximum effectiveness.
Early Mobilization
As with any critically ill patient, early mobilization is a key component of a patient’s full recovery. Prolonged immobili­zation can lead to multiple issues such as joint immobility, weakness, deep vein thrombosis, pressure ulcers, and neu­ropathies. The challenge with mobilizing burn patients early in their intensive care unit stay is often limited by the need for frequent surgeries and post-operative restrictions with splints. When a patient undergoes a skin graft procedure that crosses a joint, the area is often splinted until the first dress-

ing take down. This may limit the patient’s ability to move and ambulate. However, ambulation should be started as soon as possible. The therapist will need a complete under­standing of graft placement, ROM restrictions that may apply, as well as weight bearing precautions prior to initiating any mobility. A double layer of elastic compression should be applied starting from the toes and ending proximal to the grafted skin prior to ambulation. Initial ambulation should be limited in distance to avoid risk to the skin graft. Assistive devices should be utilized to aid the patient with stability and allow for adherence to weight bearing restrictions. In sum­mary, the key points to allow early mobilization of burn patients are good communication with a multidisciplinary team, as well as the patient, good understanding of ROM and weight bearing precautions, application of a double layer of elastic compression, and sufficient assistance to allow the patient to have a successful experience.

Early Therapeutic Intervention
“Early therapeutic intervention in the burn unit has long term implications for restoration of function” [1]. Initiating therapy in the early phase of burn care in the form of stretch­ing and exercise among other therapeutic interventions can contribute greatly to the prevention of contractures. Therapists will engage patients in either active ROM, active assisted ROM, or passive ROM depending on patients’ medical con­dition. Ideally, active ROM is the goal as it assists in reducing edema and stretches healing tissue as well as promotes strength, endurance, and function. If a patient is having diffi­culty moving through their full ROM due to strength, endur­ance, tightness, or interference of medical equipment, active assistive ROM may be performed. For those patients who are critically ill or sedated, passive ROM is appropriate for a therapist to perform to help preserve ROM and prevent con­tractures. Once a patient is actively participating in their rehabilitation program, strengthening is also introduced into

the program. Strengthening exercises can be in the form of isometric or isotonic exercises depending on the patient’s condition. Endurance will also be a factor during therapeutic exercise. Shorter treatment sessions twice (or more) a day vs. one session per day may be beneficial if a patient is inhibited by low endurance.
Scar Management, aRehabilitation Perspective
Scar is a natural part of the healing process and is defined as fibrous tissue replacing normal tissue that was destroyed by injury or disease [2]. Hypertrophic scar is characterized as having excess amounts of collagen which contributes to a red, raised scar but not to the extent of a keloid. It is also noted to not extend beyond the boundary of its original injury. It can promote scar contracture, but it can also regress with time. A keloid scar can appear as rounded pro­tuberances that can be anywhere from pink to purple in color and extend beyond the boundaries of the original wound. Scar contracture is not common with keloids, but they do not regress over time and can recur after surgical intervention. The concerns for scarring in a burn injury are functional deficits as well as the psychosocial impact of scar­ring and its effect on cosmesis. It is important to provide education to patients and families regarding scar forma­tion—the what, why, and how of development and treat­ment as well as to provide resources for psychological support for a patient and their family.
Burn patients are at risk for hypertrophic scarring. The time it takes for healing of a burn wound or skin graft (>2–3 weeks) contributes to hypertrophic scarring. Burn scars can take up to 2years for full maturation.
