Hydrotherapy Applications and Techniques

Hydrotherapy Applications

• Hydrotherapy uses various pools and techniques for treatment.
• Heating or cooling applications are used in hydrotherapy pools.
• Underwater exercises are an important part of hydrotherapy.
• Mechanical massage effects are achieved by using hydrotherapy.
• Debridement of wounds and dressings can be facilitated by hydrotherapy.

Specific Advantages of Pools and Tanks

• Effective heat transfer during treatment.
• Secure patient positioning is possible.
• Improved muscle movement compared to land-based exercises.
• Combination of heating and movement is possible simultaneously.

Disadvantages of Whirlpools

• Tank size may limit the amount and types of exercises possible.
• Requires significant space.
• Cross-infection is a concern.
• Substantial amount of water is required
• Time-consuming process, especially during filling, emptying, and cleaning

Indications for Hydrotherapy

• Muscular spasms
• Back pain
• Chronic musculoskeletal conditions
• Preliminary treatment for other modalities

Contraindications for Hydrotherapy

• Advanced peripheral vascular disease
• Arterial insufficiency
• Diabetes
• Loss of sensation
• Hydrophobia
• Fecal/urine incontinence

Different Applications and Techniques

• Pools: Whirlpool, Hubbard tank, Contrast baths, Hot packs, Paraffin
• Whirlpool bath: Local bath for extremities, rapidly circulating water, extremity tanks for upper/lower extremities, high/low boy tanks for total body immersion.
• Hubbard tank: Large, keyhole-shaped bath for total body immersion, made of plastic or stainless steel, dimensions 2m length, 1.5m width, 1m depth, includes accessories like stretchers and overhead carriers for non-ambulatory patients.
• Contrast baths: Alternating immersion in hot and cold water, improves neural activity and considered vascular exercise. Prepares with 10-minute hot application.

Hubbard Tank System

• Similar to whirlpool bath in terms of function, but allows more assisted exercises, resisted exercises, and stretching.

Bath Temperature

• Temperature range typically 36°C - 39°C
• Lower than whirlpool because total body immersion reduces sweating

Specific Hubbard Tank Advantages

• Therapist does not have to enter the tank.
• Provides space for upper/lower extremity exercises.
• Suitable for gait and walking exercises, especially for patients unable to use standard hydrotherapy pools.

Hubbard Tank Disadvantages

• No buoyancy assistance.
• Time-consuming procedures, such as filling, emptying, and cleaning.
• Large amount of water required.
• Therapists may have limited access to patients.
• The therapist's position may not be ideal, especially when leaning over the tank edge.

Application of Exercises in Hubbard Tanks

• Various exercises can be done inside the Hubbard tank, such as dipping, wrapping, and immersion

Contrast Baths

• Alternating immersion in hot and cold water
• Improvement in neural activity
• Thought of as vascular exercise
• Hot application of 10 minutes needed before contrast bath procedure

Physiological Effects of Contrast Baths

• Immediate vasodilation
• Increase in skin temperature
• Rapid increase in circulation
• Marked sedative effect
• Effects last longer than heat or cold alone

Specific Indications for Contrast Baths

• Excessive sweating (hyperhidrosis)

Hydrocollator Packs

• Equipment includes the hydrocollator unit, hot packs and towels
• Definition: Stainless-steel tank for heating hydrophilic silica gel packs.
• Features include insulated bases, wire racks to maintain spacing between packs and prevent contact with the bottom of the tank.
• Temperature range is 76°C to 80°C

Silica Gel Packs

• Used extensively in hydrocollator units

Covering (Padding) Technique

• Technique involving the use of covering materials

Commercial Towels

• Commercially produced towels used in treatment

Considerations for Hydrocollator use

• Patient positioning is critical to avoid forcing silicate gel out through the covering fabric sleeves.
• Therapist may adjust patient position, support weight, or add additional towels or pillows for support.

Paraffin Bath

• Conductive heat therapy using a mixture of paraffin and mineral oil
• Proportion of 4 units of wax to 1 unit of oil, or sometimes 6 or 7 units of wax to 1 unit of oil.
• Heated mixture is applied to a body part

Patient Tolerance for Paraffin Bath

• Well tolerated due to lower specific heat of wax compared to water.
• Wax releases less energy during cooling.
• Good insulation resulting in prolonged low-level heating.

Paraffin Bath Equipment

• Wax is placed in a bath, either small or large.
• Metal baths have electric heating elements and a large jacket around the tank.
• Lightweight machine.
• Bottom of the bath is covered with bakelite slats.
• Lid is used to cover the bath.
• Average capacity roughly 25 kg.

Paraffin Bath Advantages

• Well-tolerated.
• Easily performed.
• Suitable for home routine.

Paraffin Bath Disadvantages

• Messy; not easily applied to proximal body parts.
• Requires effort to maintain cleanliness.

Paraffin Bath Application Techniques

• Dipping, followed by wrapping.
• Dipping, followed by immersion.
• Wrapping.

Modified Paraffin Bath Techniques

• Dipping and elevation combined
• Dipping and active exercises (use paraffin to shape and exercise fingers/hands)

Using Paraffin Bath over Skin Grafts

• Graft should be stable and non-fragile.
• Treatment for skin grafts should be 10 days after grafting.
• Daily treatment for skin grafting should be 2-3 weeks.
• Temperature should be around 47°C.

Paraffin Bath Notes

• Range of motion may increase 7-10 degrees after application.
• Useful for non-flare phases to reduce pain and increase extensibility.
• Modified dipping/elevation technique suitable for edematous extremities.
