Aquatic therapy
Specialty physical therapy

Aquatic therapy refers to treatments and exercises performed in water for relaxation, fitness, physical rehabilitation, and other therapeutic benefit. Typically a qualified aquatic therapist gives constant attendance to a person receiving treatment in a heated therapy pool. Aquatic therapy techniques include Ai Chi, Aqua Running, Bad Ragaz Ring Method, Burdenko Method, Halliwick, Watsu, and other aquatic bodywork forms. Therapeutic applications include neurological disorders, spine pain, musculoskeletal pain, postoperative orthopedic rehabilitation, pediatric disabilities, pressure ulcers, and disease conditions, such as osteoporosis.

Overview

Aquatic therapy refers to water-based treatments or exercises of therapeutic intent, in particular for relaxation, fitness, and physical rehabilitation. Treatments and exercises are performed while floating, partially submerged, or fully submerged in water. Many aquatic therapy procedures require constant attendance by a trained therapist, and are performed in a specialized temperature-controlled pool. Rehabilitation commonly focuses on improving the physical function associated with illness, injury, or disability. [1] [2]

Aquatic therapy encompasses a broad set of approaches and techniques, including aquatic exercise, physical therapy, aquatic bodywork, and other movement-based therapy in water (hydrokinesiotherapy). Treatment may be passive, involving a therapist or giver and a patient or receiver, or active, involving self-generated body positions, movement, or exercise. Examples include Halliwick Aquatic Therapy, Bad Ragaz Ring Method, Watsu, and Ai chi. [1]

For orthopedic rehabilitation, aquatic therapy is considered to be synonymous with therapeutic aquatic exercise, aqua therapy, aquatic rehabilitation, water therapy, and pool therapy. Aquatic therapy can support restoration of function for many areas of orthopedics, including sports medicine, work conditioning, joint arthroplasty, and back rehabilitation programs. A strong aquatic component is especially beneficial for therapy programs where limited or non-weight bearing is desirable and where normal functioning is limited by inflammation, pain, guarding, muscle spasm, and limited range of motion (ROM). Water provides a controllable environment for reeducation of weak muscles and skill development for neurological and neuromuscular impairment, acute orthopedic or neuromuscular injury, rheumatological disease, or recovery from recent surgery. [3] :1

Various properties of water contribute to therapeutic effects, including the ability to use water for resistance in place of gravity or weights; thermal stability that permits maintenance of near-constant temperature; hydrostatic pressure that supports and stabilizes, and that influences heart and lung function; buoyancy that permits flotation and reduces the effects of gravity; and turbulence and wave propagation that allow gentle manipulation and movement. [4]

History

The use of water for therapeutic purposes first dates back to 2400 B.C. in the form of hydrotherapy, with records suggesting that ancient Egyptian, Assyrian, and Mohammedan cultures utilized mineral waters which were thought to have curative properties through the 18th century. [5]

In 1911, Dr. Charles Leroy Lowman began to use therapeutic tubs to treat cerebral palsy and spastic patients in California at Orthopedic Hospital in Los Angeles. Lowman was inspired after a visit to Spaulding School for Crippled Children in Chicago, where wooden exercise tanks were used by paralyzed patients. [6] The invention of the Hubbard Tank, developed by Leroy Hubbard, launched the evolution of modern aquatic therapy and the development of modern techniques including the Halliwick Concept and the Bad Ragaz Ring Method (BRRM). [5] Throughout the 1930s, research and literature on aquatic exercise, pool treatment, and spa therapy began to appear in professional journals. Dr. Charles Leroy Lowman's Technique of Underwater Gymnastics: A Study in Practical Application, published in 1937, introduced underwater exercises that were used to help restore muscle function lost by bodily deformities. [6] The National Foundation for Infantile Paralysis began utilizing corrective swimming pools and Lowman's techniques for treatment of poliomyelitis in the 1950s. [6]

The American Physical Therapy Association (APTA) recognized the aquatic therapy section within the APTA in 1992, after a vote within the House of Delegates of the APTA in Denver, CO after lobbying efforts spearheaded starting in 1989 by Judy Cirullo and Richard C. Ruoti. [7]

Techniques

Techniques for aquatic therapy include the following: [1] [8]

Applications and effectiveness

Applications of aquatic therapy include neurological disorders, [18] spine pain, [19] musculoskeletal pain, postoperative orthopedic rehabilitation, pediatric disabilities, pressure ulcers, [1] and other disease conditions, such as osteoporosis.

A 2006 systematic review of effects of aquatic interventions in children with neuromotor impairments found "substantial lack of evidence-based research evaluating the specific effects of aquatic interventions in this population". [20]

For musculoskeletal rehabilitation, aquatic therapy is typically used to treat acute injuries as well as subjective pain of chronic conditions, such as arthritis. Water immersion has compressive effects and reflexively regulates blood vessel tone. Muscle blood flow increases by about 225% during immersion, as increased cardiac output is distributed to skin and muscle tissue. [21] Flotation is able to counteract the effects of gravitational force on joints, creating a low impact environment for joints to perform within. The temperature changes, increase in systolic blood pressure to extremities, and overall increase in ambulation are factors which help immersion to alleviate pain. Aquatic Therapy helps with pain and stiffness, but can also improve quality of life, tone the muscles in the body, and can help with movement in the knees and hips. Protocols using a combination of strengthening, flexibility, and balance exercises resulted in the greatest improvements in Childhood Health Assessment Questionnaire scores, whereas aerobic exercise did not result in greater improvements in CHAQ scores compared to a comparison group performing Qigong. [22] Not only does aquatic therapy help with pain, but can benefit postural stability, meaning it can help to strengthen balance functions especially with people who have neurological disorders. For people diagnosed with Parkinson's disease, aquatic exercise has been proven to be more beneficial than land-based exercise for two important outcome measures. The Berg Balance Scale and Falls Efficacy Scale score were reported to have significant improvement when implementing aquatic exercise over land-based exercise. These results suggest that aquatic exercise can be extremely helpful for Parkinson's disease patients with specific balance disorders and fear of falling. [23]

Aquatic therapy in warm water has been shown to have a positive effect on the aerobic capacity of people with fibromyalgia. It is still inconclusive whether land therapy is better than aquatic therapy however it has been demonstrated that aquatic therapy is as effective as land base therapy. There are advantageous outcomes for patients with fibromyalgia resulting from aquatic therapy such as decrease of articulate load regarding an individual's biomechanics. [24]

Currently there is no standardized aquatic therapy protocol for people post stroke however it is safe to conclude that aquatic therapy can be more effective than land based therapy for improving balance and mobility. There is insufficient evidence regarding improvements in functional independence of people post stroke. [25]

From a cardiopulmonary standpoint, aquatic therapy is often used because its effects mirror land-based effects but at lower speeds. During immersion, blood is displaced upwards into heart and there is an increase in pulse pressure due to increased cardiac filling. Cardiac volume increases 27-30%. Oxygen consumption is increased with exercise, and heart rate is increased at higher temperatures, and decreased at lower temperatures. However, immersion can worsen effects in cases of valvular insufficiency due to this cardiac and stroke volume increase. The aquatic environment is also not recommended for those who experience severe or uncontrolled heart failure. [21]

Aquatic therapy can be used for younger populations or in a pediatric setting. Aquatic therapy improves the trunk structure involved in gross motor function. The role of physical therapists is early intervention to improve their physical, mental, and social recovery. There are different interventions or activity sequences that can be implemented using aquatic therapy to improve specific functions or address specific disabilities in children. In regards to children and aquatic therapy, studies show that aquatic therapy improves motor symptoms, increases physical activity levels (which can be maintained over a long period of time) in children with developmental or motor disabilities. It also has a positive influence on social interactions/behaviors, and participation in children with neurological disorders. [26] Aquatic therapy is beneficial for people with spinal cord injury or disorder. Aquatic therapy promotes physical and psychosocial benefits for patients with spinal cord injury and disorders. In a study, underwater treadmill training improved lower extremity strength, balance and gait in people who suffer from partial damage to their spinal cord. Respiratory function also improved with underwater treadmill training in these individuals. Knowledge of how to use aquatic therapy in application to people with spinal cord injuries or disorders is important because access to aquatic therapy is limited in this population even though there is evidence of significant improvement of many systems/ overall function using aquatic therapy. [27]

Multiple Sclerosis or MS, is a disabling disease that affects one's central nervous system. MS will target the protective sheath (myelin) that covers the nerves. Myelin allows for communication. The destruction of myelin would result in poor communication between the brain and the body. Those with MS will experience neurological damage that impacts physical, cognitive, and psychological and emotional functioning, as well as quality of life. [28] Aquatic therapy offers benefits for this population. By utilizing the physical properties of water such as buoyancy, turbulence, hydrostatic pressure, and hydrostatic resistance, MS patients would be able to work on balance and coordination. This being something that had been compromised with the progression of the disease. The viscosity or thickness of water, allows for MS patients to take their time with their movements. The viscous environment would result in slower more careful movement. Aquatic therapy also offers the benefit of being able to actively use your muscle in order to maintain stabilization within the water itself. Finally, another potential benefit of aquatic therapy and patients with MS is the temperature of the water creating a comfortable environment. Patients with MS experience increased body temperature. Some authors have recommended that water temperature be below 85 °F (29.4 °C) for MS patients. In the exercise program, a temperature range of 83 °F to 85 °F (28.3 °C -29.4 °C) is recommended for low-repeat and low resistance exercises. [29] The benefits of using aquatic therapy would result in a cool-down effect, that would essentially create a more optimal central temperature eventually increasing the ability to perform exercises effectively.

Exercise has been shown to decrease the number of osteoporotic fractures in postmenopausal adults. [30] However, the risk of falling along with the intense weight bearing (WB) and dynamic resistance exercises recommended to improve bone mineral density (BMD) typically conflicts with the proclivity of many older and vulnerable individuals. [31] Research shows that the properties of water utilized during Aquatic Therapy, such as buoyancy and water resistance have made statically significant improvements in the BMD of patient’s Lumbar Spine (LS) and proximal Femoral Neck (FN), the most important sites for osteoporotic fractures. Due to its safety, Aquatic Therapy is recommended for individuals unable, unmotivated, or scared to perform intense land exercises. Further research is to be completed to determine the effects of specific aquatic exercise properties, such as intensity, frequency and duration on BMD in order to provide effective aquatic program recommendations. [32]

Professional training and certification

Aquatic therapy is performed by diverse professionals with specific training and certification requirements. An aquatic therapy specialization is an add-on certification for healthcare providers, mainly including physical therapists and athletic trainers. [33]

For medical purposes, aquatic therapy, as defined by the American Medical Association (AMA), can be performed by various legally-regulated healthcare professionals who have scopes of practice that permit them to offer such services and who are permitted to use AMA Current Procedural Terminology (CPT) codes. [34] Currently, aquatic therapy certification is provided by the Aquatic Therapy and Rehab Institute (ATRI), which aims to further education for therapists and healthcare professionals working in aquatic environments. The ATRI prerequisites for certification include 15 hours of Aquatic Therapy, Rehab and/or Aquatic Therapeutic Exercise education, which can be completed hands-on or online. Once completing the prerequisites, those pursuing certification can take the Aquatic Therapy & Rehab Institutes Aquatic Therapeutic Exercise Certification exam. [35]

Hypertonia is a term sometimes used synonymously with spasticity and rigidity in the literature surrounding damage to the central nervous system, namely upper motor neuron lesions. Impaired ability of damaged motor neurons to regulate descending pathways gives rise to disordered spinal reflexes, increased excitability of muscle spindles, and decreased synaptic inhibition. These consequences result in abnormally increased muscle tone of symptomatic muscles. Some authors suggest that the current definition for spasticity, the velocity-dependent over-activity of the stretch reflex, is not sufficient as it fails to take into account patients exhibiting increased muscle tone in the absence of stretch reflex over-activity. They instead suggest that "reversible hypertonia" is more appropriate and represents a treatable condition that is responsive to various therapy modalities like drug or physical therapy.

<span class="mw-page-title-main">Telerehabilitation</span> Delivery of rehabilitation services over the internet

Telerehabilitation (or e-rehabilitation is the delivery of rehabilitation services over telecommunication networks and the internet. Telerehabilitation allows patients to interact with providers remotely and can be used both to assess patients and to deliver therapy. Fields of medicine that utilize telerehabilitation include: physical therapy, occupational therapy, speech-language pathology, audiology, and psychology. Therapy sessions can be individual or community-based. Types of therapy available include motor training exercises, speech therapy, virtual reality, robotic therapy, goal setting, and group exercise.

Virtual reality therapy (VRT), also known as virtual reality immersion therapy (VRIT), simulation for therapy (SFT), virtual reality exposure therapy (VRET), and computerized CBT (CCBT), is the use of virtual reality technology for psychological or occupational therapy and in affecting virtual rehabilitation. Patients receiving virtual reality therapy navigate through digitally created environments and complete specially designed tasks often tailored to treat a specific ailment; and is designed to isolate the user from their surrounding sensory inputs and give the illusion of immersion inside a computer-generated, interactive virtual environment. This technology has a demonstrated clinical benefit as an adjunctive analgesic during burn wound dressing and other painful medical procedures. Technology can range from a simple PC and keyboard setup, to a modern virtual reality headset. It is widely used as an alternative form of exposure therapy, in which patients interact with harmless virtual representations of traumatic stimuli in order to reduce fear responses. It has proven to be especially effective at treating PTSD, and shows considerable promise in treating a variety of neurological and physical conditions. Virtual reality therapy has also been used to help stroke patients regain muscle control, to treat other disorders such as body dysmorphia, and to improve social skills in those diagnosed with autism.

Therapeutic ultrasound refers generally to any type of ultrasonic procedure that uses ultrasound for therapeutic benefit. Physiotherapeutic ultrasound was introduced into clinical practice in the 1950s, with lithotripsy introduced in the 1980s. Others are at various stages in transitioning from research to clinical use: HIFU, targeted ultrasound drug delivery, trans-dermal ultrasound drug delivery, ultrasound hemostasis, cancer therapy, and ultrasound assisted thrombolysis It may use focused ultrasound or unfocused ultrasound.

Equine-assisted therapy (EAT) encompasses a range of treatments that involve activities with horses and other equines to promote human physical and mental health. Modern use of horses for mental health treatment dates to the 1990s. Systematic review of studies of EAT as applied to physical health date only to about 2007, and a lack of common terminology and standardization has caused problems with meta-analysis. Due to a lack of high-quality studies assessing the efficacy of equine-assisted therapies for mental health treatment, concerns have been raised that these therapies should not replace or divert resources from other evidence-based mental health therapies. The existing body of evidence does not justify the promotion and use of equine-related treatments for mental disorders.

The Halliwick Concept focuses on biophysical principles of motor control in water, in particular developing sense of balance (equilibrioception) and core stability. The Halliwick Ten-Point-Programme implements the concept in a progressive programme of mental adjustment, disengagement, and development of motor control, with an emphasis on rotational control, and applies the programme to teach physically disabled people balance control, swimming, and independence. Halliwick Aquatic Therapy, implements the concept in patient-specific aquatic therapy for application in rehabilitation of injury and disability.

<span class="mw-page-title-main">Management of cerebral palsy</span>

Over time, the approach to cerebral palsy management has shifted away from narrow attempts to fix individual physical problems – such as spasticity in a particular limb – to making such treatments part of a larger goal of maximizing the person's independence and community engagement. Much of childhood therapy is aimed at improving gait and walking. Approximately 60% of people with CP are able to walk independently or with aids at adulthood. However, the evidence base for the effectiveness of intervention programs reflecting the philosophy of independence has not yet caught up: effective interventions for body structures and functions have a strong evidence base, but evidence is lacking for effective interventions targeted toward participation, environment, or personal factors. There is also no good evidence to show that an intervention that is effective at the body-specific level will result in an improvement at the activity level, or vice versa. Although such cross-over benefit might happen, not enough high-quality studies have been done to demonstrate it.

When treating a person with a spinal cord injury, repairing the damage created by injury is the ultimate goal. By using a variety of treatments, greater improvements are achieved, and, therefore, treatment should not be limited to one method. Furthermore, increasing activity will increase his/her chances of recovery.

Watsu is a form of aquatic bodywork used for deep relaxation and passive aquatic therapy. Watsu is characterized by one-on-one sessions in which a practitioner or therapist gently cradles, moves, stretches, and massages a receiver in chest-deep warm water.

The Bad Ragaz Ring Method (BRRM) is a type of aquatic therapy used for physical rehabilitation based on proprioceptive neuromuscular facilitation (PNF). BRRM is a water-based technique in which therapist-assisted strengthening and mobilizing exercises are performed while the patient lies horizontally in the water, with support provided by rings or floats around the neck, arms, pelvis, and legs.

Video game rehabilitation is a process of using common video game consoles and methodology to target and improve physical and mental weaknesses through therapeutic processes. Video games are becoming an integral part of occupational therapy practice in acute, rehabilitation, and community settings. The design for video games in rehabilitation is focused on a number of fundamental principles, such as reward, goals, challenge, and meaningful play. 'Meaningful play' emerges from the relationship between player action and system outcome, apparent to the player through, visual, physical and aural feedback. Platforms that feature motion control, notably the Nintendo Wii, Microsoft's Xbox Kinect, Sony's Eye Toy, and virtual reality have all been effective in this field of research. Methodologies have been applied to all age groups, from toddlers to the elderly. It has been used in a variety of cases ranging from stroke rehabilitation, cerebral palsy and other neurological impairments, to tendinitis and multiple sclerosis. Researchers have promoted such technology based on the personalization of gaming systems to patients, allowing for further engagement and interaction. Additionally, gaming consoles have the ability to capture real-time data and provide instant feedback to the patients using the systems. Currently, several researchers have performed case studies to demonstrate the benefits of this technology. Repeat trials and experiments have shown that outcomes are easily replicated among various groups worldwide. Additionally, the outcomes have increased interest in the field, growing experiments beyond simple case studies to experiments with a larger participant base.

<span class="mw-page-title-main">Vestibular rehabilitation</span> Form of physical therapy for vestibular disorders

Vestibular rehabilitation (VR), also known as vestibular rehabilitation therapy (VRT), is a specialized form of physical therapy used to treat vestibular disorders or symptoms, characterized by dizziness, vertigo, and trouble with balance, posture, and vision. These primary symptoms can result in secondary symptoms such as nausea, fatigue, and lack of concentration. All symptoms of vestibular dysfunction can significantly decrease quality of life, introducing mental-emotional issues such as anxiety and depression, and greatly impair an individual, causing them to become more sedentary. Decreased mobility results in weaker muscles, less flexible joints, and worsened stamina, as well as decreased social and occupational activity. Vestibular rehabilitation therapy can be used in conjunction with cognitive behavioral therapy in order to reduce anxiety and depression resulting from an individual's change in lifestyle. However, there is often confusion about whether vestibular rehabilitation falls under physical therapy (PT) or occupational therapy (OT).

<span class="mw-page-title-main">Hydrogymnastics</span>

Hydrogymnastics is a water-based therapeutic exercise. As its name suggests, this form of aquatic therapy or aquatic rehabilitation is performed in water, and it can take place in swimming pools at aquatic leisure centres and/or in home pools. Being a form of aquatic therapy, hydrogymnastics aims to improve the physical and psychological health and well-being of an individual. Hydrogymnastics can be performed by anyone, including youths, middle-aged people, the elderly, athletes and those with disabilities. Hydrogymnastics is often assisted by a qualified aquatic therapist and/or exercise physiologist. Although the effects of hydrogymnastics may vary between individuals belonging to different age groups and genders, hydrogymnastics mainly improves one's cardiovascular fitness, strength, balance and mobility.
