Study Notes

Hydrotherapy Overview

Hydrotherapy utilizes water to facilitate healing and exercise, enabling patients to achieve therapy goals.
Types include aquatic/pool therapy, whirlpool hydrotherapy, and contrast baths.

Hydrotherapy Objectives

Students will describe various types of hydrotherapy.
Students will describe the physical properties of water, physiological responses, and mechanical effects.
Students will describe therapeutic benefits of hydrotherapy, components and care of a therapeutic whirlpool, benefits of aquatic exercise and water activities, benefits of hydrotherapy for wound management, general technique/application, dosage and frequency for aquatic/hydro-therapy, including indications, contraindications, and precautions.

Hydrotherapy Defined

Hydrotherapy is the use of water to promote healing and enable patients to meet therapy goals through exercise.
Aquatic or pool therapy is a specific type focused on in this course.
Whirlpool hydrotherapy and contrast baths are other types.

Physical Properties of Water: Buoyancy

Buoyancy Principle: The buoyant force on a body immersed in a fluid equals the weight of the fluid displaced by the object.
Center of Buoyancy (COB) is typically at the sternum.
Center of Gravity (COG) is anterior to the sacrum.
Patients with missing limbs compensate by bending toward the remaining limb for balance.
Buoyancy-assisted (BA) movement is vertical, parallel to buoyancy forces.
Buoyancy-supported (BS) movement is horizontal, minimizing the need to support an extremity against gravity.
Buoyancy-resisted (BR) movement opposes buoyancy forces, creating drag.
Buoyancy-super resisted (BSR) increases total surface area and speed to create more drag.

Physical Principles and Properties of Water

Objects denser than water are less buoyant and sink (increased bone density).
Objects less dense than water are more buoyant and float (fully inflated lungs, obese individuals).

Depth of Body-Weight Bearing

Neck: 10% weight-bearing.
Chest: 25% weight-bearing.
Waist: 50% weight-bearing.
Just above knees: 65% weight-bearing.

Hydrotherapy Exercises

Exercises in water consider the effects of buoyancy and body weight.

Physical Properties of Water: Viscosity

Viscosity is the internal friction in liquids due to cohesive forces between molecules.
Water's viscosity resists movement; faster movement leads to higher resistance.

Physical Properties of Water: Hydrostatic Pressure

Hydrostatic pressure is the force exerted by water on a body part based on depth.
Increased pressure at greater depths may encourage venous return and lymph flow, potentially decreasing edema.
However, a dependent position may counteract this effect and may actually encourage swelling in a limb.

Hydrostatic Pressure (Diagram)

Deeper water exerts higher pressure. The larger arrows indicate greater hydrostatic pressure deeper in the water.

Physical Properties of Water: Hydrodynamics

Turbulent water creates more resistance to movement.
Exercise in turbulent water provides higher resistance compared to still water.
Frontal resistance is the resistance to initiating movement, increasing with greater surface area.
Laminar flow is the smooth, horizontal flow of water over a body part.
Drag is a pulling force from behind that inhibits forward movement.
Exercise in water requires 33-42% more energy compared to land-based exercises.

Physiological Effects of Water

Hemodynamics (cardiovascular effects)
Respiratory System
Renal System
Neurological System
Muscular System

Hemodynamics: Cardiac Function

Dive reflex: Occurs when most of the body is immersed, resulting in bradycardia (slower heart rate).
Peripheral vasoconstriction and blood shunting to vital organs also occur.
Warm/hot water increases heart rate.
Body temperature water has a neutral effect on heart rate.

Respiratory and Renal Systems

Hydrostatic pressure against the chest inhibits lung expansion.
Increased circulation to the center of the body also inhibits lung expansion.
Maximal oxygen uptake is lower in water compared to land-based exercise.
Renal function shows increased urine output, sodium excretion, and potassium excretion.

Neurological System

Warm water is generally relaxing.
Cold water can be stimulating or invigorating.

Muscular System

Warm water increases muscular blood flow.
Water agitation relaxes muscle spasms through sensory stimulation.
Exercising against water turbulence increases strength.
Cold water provides stimulation.
Analgesia (pain relief) is a benefit of both warm and cold water.

Physical Properties of Water: Thermodynamics/Heat Transfer

Physiological effects of hydrotherapy depend on water temperature, the amount of body immersed, and whether the person is at rest or moving.
Water transfers heat 25 times faster than air.

Aquatic Therapy and Water Temperature

Vary degrees for differing therapy needs based on the condition.
Specific conditions and populations require particular temperature ranges.
High-intensity aerobic exercise is best performed in lower temperatures.

Aquatic Therapy and Exercise (Special Populations)

Special populations (e.g. rheumatoid arthritis, spasticity, multiple sclerosis) may require specialized hydrotherapy approaches and considerations for temperature and duration.

Hydrotherapy: Pool/Aquatic Therapy (General Technique/Application)

Choosing the correct water temperature
Reviewing medications and precautions
Ensuring safety (clothing, shoes, changing areas)
Facilitating and assisting transfers (ramps, stairs, lifts)
Addressing fear of water, expectations
Utilizing equipment (floats, paddles, vests, flippers, weights, treadmill)

Progression of Exercises

Increasing the moving body part's surface area challenges exercises.
Exercising against turbulence or buoyancy increase challenge to the movement.
Increasing movement speed and changing direction add to the challenge.
Exercising closer to the surface involves surface tension.

Hydrotherapy: Outcomes (Measure Effects on Impairments)

Pain
Range of motion (ROM) improvements
Strength improvement
Edema reduction
Balance & coordination improvements
Functional capacity improvements, measured using various tools such as the Functional Independence Measure (FIM), Oswestry Disability Index, or other related assessments.

Aquatic Therapy Documentation

Water temperature
Treatment duration
Therapy goals
Exercises/movements used
Equipment used
Patient tolerance and response, including vital signs
Means of entry/exit
Adverse reactions
Post-therapy changes

Hydrotherapy: Evidence

Hydrotherapy can improve exercise capacity, muscle strength, and quality of life in patients with heart failure.
Hydrotherapy can be effective in the management of rheumatoid arthritis, reducing pain.

Clinical Controversy

High cost of resources compared to land-based programs.
Chronic nature of some conditions necessitates long-term aquatic programs.
Determining the effectiveness and sufficiency of land-based programs compared to aquatic programs.
Determining optimal session frequency.
Determining appropriate times for progression from PT to community-based programs.

Whirlpool Hydrotherapy

Water agitation with an electric motor is used.
Concerns regarding wound infection and costs have led to decreased use, in some areas.

Whirlpool Hydrotherapy: Indications

Wound debridement and preparation for debridement.
Treatment of Stage III or IV pressure ulcers with less than 50% necrotic tissue.
Cleaning wounds with excess exudate, loose debris, or foreign bodies, or localized infection.
Venous and arterial ulcers.

Whirlpool Hydrotherapy: Precautions

Healing wounds with granulation tissue.
Edematous extremities.
Patient sensitivity or allergies to additives in the water.
Presence of catheters.
Seizure disorders.
Tracheostomy.

Whirlpool Hydrotherapy: Contraindications

Split or full thickness grafts.
IV lines.
Colostomy.
Incontinence
Fever

Hydrotherapy: Hubbard Tanks

Large, full-body immersion tanks, similar to a large whirlpool.

Hydrotherapy: Whirlpool Turbine

Hydrotherapy: Whirlpools (Responses/Modifications)

Dependent position can cause edema.
Using padding or towels to support while minimizing constriction of circulatory/lymphatic systems.
Normal response includes pink, wrinkled skin, and mild perspiration.

Whirlpool Cleaning

Drain and clean whirlpool after each use.
Spray tank with disinfectant.
Let disinfectant sit for 5 minutes.
Wash with wet cloth and rinse.
Wipe the outside of the tank with a stainless-steel cleaner.
Use Material Safety Data Sheets for all cleaning products.

Turbine Disinfecting

Disinfecting the turbine requires use of a bucket filled with water and disinfectant, running the turbine for 5 minutes. The turbine is set at its lowest speed, and fills the bucket ensuring that the lowest air hole is covered.

Whirlpool Effectiveness

Effects are seen on the inflammatory phase of a wound.
Warm water leads to vasodilation of superficial vessels, increasing oxygen and nutrient delivery while removing cellular waste.
Fluid shifting leads to potential edema.
Water softens and loosens necrotic tissue, removes wound exudate, and stimulates granulation tissue formation.
Warm water induces sedation and analgesia.

Hydrotherapy: Pulsed Lavage

Delivers wound irrigation under controlled pressure.
Irrigating wounds with saline or tap water using pulsatile pressure.

Hydrotherapy: Pulsed Lavage (Purpose and Effects)

Decreasing bacteria and infection.
Promoting granulation and epithelialization.

Hydrotherapy: Pulsed Lavage (Indications)

Wounds resulting from arterial or venous insufficiency, diabetes, pressure sores, small burns, surgery, or trauma.

Hydrotherapy: Pulsed Lavage (Precautions and Contraindications)

Precautions for bleeding wounds, sensitive tissue, or anticoagulant use, insensate patients.
Contraindications for injuries (recent tissue grafts, flaps, surgical procedures, exposed vessels, tendons, joints, or deep-cavity wounds).
Appropriate dosages (15-30 minutes; 4-15 psi; daily- 3x/week)

Hydrotherapy: Pulsed Lavage (Responses/Modifications)

Dosage modifications may be required for pain management.
Topical Lidocaine might be used prior to treatment to reduce discomfort .

Contrast Baths

Alternating immersion in hot and cold baths.
Vascular pumping stimulated by vasodilation and vasoconstriction, locally improving superficial circulation.
Indications include pain relief and desensitization, specifically for CPRS or DOMS (delayed onset muscle soreness).
Precautions include awareness of heat/cold sensitivities, and potential exacerbation of edema in acute injuries.

Contrast Baths (Technique)

Two tubs or whirlpools are used, one for cold water (55-65°F) and one for hot water (100-110°F).
Hot-to-cold immersion ratios range from 3:1 to 4:2, and treatment times are 25-30 minutes, with the last immersion typically in hot water (for chronic conditions) or cold for edema reduction.
