Study Notes
Cardiovascular System
- Hydrostatic pressure increases venous return, leading to increased atrial pressure.
- Cardiac output increases significantly, reaching 8.6 L/min at 86 bpm with increased stroke volume.
- Systemic vascular resistance decreases.
Pulmonary System
- Hydrostatic pressure reduces rib cage circumference by approximately 10%.
- Vital capacity decreases by 6-9%.
- Pulmonary blood flow increases.
- Total work of breathing increases by 60% when water reaches neck level.
Renal System
- Increased blood flow leads to enhanced creatinine clearance, sodium excretion, and potassium excretion.
- This, in turn, increases diuresis.
- Hydrotherapy with full-body immersion is recommended for edema management in nephrotic syndrome and cirrhosis patients.
Musculoskeletal System
- Resting blood flow increases by 100% to 225%.
- Enhanced muscle blood flow and oxygen delivery occur.
- Waste product removal is facilitated.
- Muscle elasticity increases.
- Buoyancy reduces joint load.
- Water's velocity allows for resistance training.
Thermotherapy
- Relieves pain.
- Enhances muscle elasticity.
- Promotes relaxation.
- Hyperemia due to increased blood flow accelerates metabolic rate, generating more heat.
Cooling Therapy
- Slows metabolic rate, decreasing metabolite production and heat generation.
- Reduces pain.
- Induces local vasoconstriction.
- Decreases cellular metabolism, minimizing edema.
- Offers deeper tissue cooling effects.
- Apply cooling therapy at least 72 hours after trauma.
Therapeutic Uses of Hydrotherapy
- Vasodilation or vasoconstriction modulation.
- Wound care (non-open wounds).
- Water-based exercise.
- Pain management.
- Edema control using hydrostatic pressure and renal function modifications.
Indications of Hydrotherapy
- Subacute or chronic soft tissue injuries.
- Muscle contractures.
- Scar formation
- Osteoarthritis.
- Subacute or chronic rheumatoid arthritis.
- Post-fracture patients.
- Open wounds.
- Burns with intact thermal sensation.
- Pressure ulcers.
- Muscle spasms.
- Tension.
- Anxiety.
- Muscle weakness due to disuse.
- Muscle weakness from central nervous system conditions (e.g., hemiplegia).
- Peripheral nervous system pathologies (e.g., polyneuropathy).
