Introduction

When we think of physical therapy, we often think of physiotherapy or some form of occupational therapy. Still, we overlook one of the most energy-intensive exercises with minimal harm and endurance training. These are activities, including aquatic physical therapy. Aquatic physical therapy, also known as hydrotherapy, is a form of rehabilitation that takes place in water. This therapeutic approach leverages the unique properties of water to provide a low-impact, high-resistance environment for exercising. This article explores the benefits of aquatic therapy and outlines some effective exercises for various conditions.

What is aquatic physical therapy?

Description and principles

Aquatic therapy refers to the incorporation of water-based exercises in therapy to treat diverse medical conditions and improve physical mobility. This therapeutic approach leverages the unique properties of water, such as buoyancy, resistance, and hydrostatic pressure for its healing purpose.

Historical background

Historically, the use of water for therapeutic purposes dates back to ancient civilizations, where it was widely used for its healing properties. It was generally followed for its ability to treat various ailments and promote general health and well-being. The modern application of aquatic therapy has undergone tremendous evolution wherein evidence-based practices are integrated with advanced techniques to diversify the treatment benefits of hydrotherapy.

Types of aquatic therapy techniques

Aquatic therapy utilises a range of techniques that leverage hydrostatic properties to address specific patient needs. 

Watsu

Watsu is a form of hydrotherapy, in which a practitioner combines various elements of massage, joint mobilization, shiatsu, and muscle stretching in a lightly high temperature of water.
The practice of Watsu requires the active involvement of a therapist who guides the movement of the patient who is chest-deep in warm water and promotes relaxation, flexibility, and pain relief. Watsu is the go-to technique of hydrotherapy in those suffering from conditions such as chronic pain and fibromyalgia and is even used to reduce stress in individuals. The guided and limited movements make it particularly helpful for patients who have compromised mobility.

Ai Chi

Jun Konno is credited with the discovery of Ai Chi, a conglomeration of the principles of Tai Chi and Qigong. It is very similar to Watsu, incorporating slow, controlled movements combined with deep breathing exercises that are usually performed in warm, chest-deep water. Ai Chi’s primary focus is on improving balance, coordination, and relaxation. As much as this is a therapeutic intervention used in the rehabilitation of patients with stroke or multiple sclerosis, it is usually practised for recreation and promoting fitness.

Aqua running

Deep-water running or Aqua running resorts to the use of a flotation belt to mimic underwater running. It is much safer and beneficial than land-based running due to its ability to provide an intense cardiovascular workout without the wear and tear caused by muscles and joints.
It is particularly helpful in the rehabilitation of injured athletes to maintain fitness without engaging in energy-intensive exercises.

Halliwick concept

This therapy focuses on engineering movement in the water to help people with physical disabilities improve their strength, balance, and coordination. It concentrates on instructing balance control and core stability via water-based exercises. Created for people with physical disabilities, the Halliwick Concept aims to gradually improve motor skills and autonomy in the water. The program focuses on mental readjustment, detachment, and control of movement, and is appropriate for individuals with neurological disorders, like cerebral palsy or spinal cord injury wounds.

Bad Ragaz ring rethod

This is a method used to improve balance and activate leg muscles, especially in patients who suffer from chronic stroke. Patients wear floating rings around their neck, pelvis, knees, and ankles while lying horizontally in water that's 33°C. The rings support the patient's body, allowing them to perform resistive exercises that strengthen and mobilize their muscles. 

Benefits of aquatic physical therapy

The benefits of aquatic therapy are many; primarily, it is beneficial in relieving pressure on bones, joints, etc, which are usually overstrained during strenuous exercises. Along with this, hydrotherapy has been beneficial in improving cardiac health, reducing symptomology in osteoarthritic individuals, etc.
The biggest advantage of aquatic therapy is for those individuals who do not know how to swim because this is an inclusive activity which can be equally participated in by the elderly as well.

Aquatic therapy offers numerous advantages over land-based exercises

Physical benefits

1. Buoyancy: The buoyant nature of water is responsible for reducing the gravitational force that would be exerted on the body. As a result, we observe reduced stress on joints and support for the body weight.
2. Hydrostatic Pressure: Improves circulation and reduces swelling
3. Resistance: Provides natural resistance for strength training
4. Temperature: Warm water helps relax muscles and reduce pain
5. Safety: Lowers risk of falls and injuries during exercise

 Psychological benefits

1. Stress relief

Aquatic physical therapy is a beneficial way to reduce stress and thereby tackle psychosomatic illnesses.

• Enhanced mood and mental health

People performing aquatic therapy exercises find themselves in a better mood and report an improvement in their overall mental health and well-being.

Specific populations that benefit

1. Elderly

The elderly are able to perform hydrotherapy without worry of straining their joints and muscles. The supervision of these exercises by qualified practitioners makes this a safe and reliable activity for senior citizens to indulge in, whether it is for rehabilitation or general fitness.

• People with chronic pain conditions

Those suffering from a myriad of chronic pain syndromes, such as Arthritis, post-surgical rehabilitation, use aquatic therapy to alleviate pain symptoms and improve physiological mobility.

• People with neurologic conditions

Hydrotherapy has been of immense help to those diagnosed with neurological insufficiency in cases of stroke, multiple sclerosis, and even cerebral palsy. The progressive therapy focuses on improving balance, gait, and posture, thereby greatly improving mobility and quality of life.

Common aquatic therapy exercises

Water walking

• Description: Walk forward, backwards, and sideways in chest-deep water
• Benefits: Improves balance, strengthens leg muscles, and enhances cardiovascular fitness
• Variations: Increase speed or add arm movements for more intensity

 Leg swings

• Description: Hold the pool edge and swing one leg forward and back, then side to side
• Benefits: Increases hip flexibility and strengthens leg muscles
• Repetitions: 10-15 swings in each direction, per leg

Pool noodle balance

• Description: Sit on a pool noodle like a horse, maintaining balance while moving arms and legs
• Benefits: Improves core strength and balance
• Duration: Start with 30 seconds and gradually increase

Aqua jogging

• Description: Use a flotation belt to jog in place in deep water
• Benefits: Provides cardiovascular exercise without joint stress
• Duration: Begin with 5 minutes and progress to 20-30 minutes

Wall push-ups

• Description: Face the pool wall, place hands on the edge, and perform push-ups
• Benefits: Strengthens chest, shoulders, and arms
• Repetitions: Start with 5-10 and increase as strength improves

Condition-specific exercises

For arthritis

1. Gentle knee lifts: Improves knee flexibility and strength
2. Water arm circles: Enhances shoulder mobility

 Safety considerations

• Patients who have a fear of water should be acclimatised to performing exercises in water. This may require the intervention of therapists to overcome the inhibition of patients towards water.
• Always consult with a healthcare professional before starting aquatic therapy to rule out the progression of the disease
• Ensure proper water temperature (typically 83-88°F or 28-31°C)
• Use appropriate flotation devices when necessary
•  Stay hydrated, even when in the water
•  Never exercise alone; always have supervision to avoid sinking or the risk of being unattended while facing a medical emergency

Frequently asked questions
