Study Notes
Hydrotherapy Overview
- Hydrotherapy dates back to ancient cultures as a therapeutic method for various ailments.
- It utilizes water in various forms (liquid, solid, gas) and temperatures for treatment.
- Water types used include fresh, mineral, marine, and can be infused with medicinal substances like herbs and salts.
Properties of Water in Hydrotherapy
- Chemical Properties: Water is a polar molecule (H2O) with high dissolving power, aiding in the treatment of wounds and infections.
- Physical and Mechanical Properties:
- Buoyancy: Objects immersed in water experience reduced gravity, assisting with movement and reducing stress on joints.
- Immersion up to different body levels affects weight-bearing:
- Neck: 10% body weight
- Xiphoid process: 33% body weight
- Anterior superior iliac spine: 50% body weight
- Immersion up to different body levels affects weight-bearing:
- Specific Gravity: Determines buoyancy; objects with a specific gravity <1 float, while those >1 sink.
- Human bodies generally float with a specific gravity around 0.96, influenced by lung inflation and body composition.
- Viscosity: Internal friction in water resists limb movement; faster movement increases resistance.
- Hydrostatic Pressure: Water exerts equal pressure on immersed body parts; pressure increases with depth.
- Drag Force: Resists movement in water, influenced by movement direction and surface area; faster movement leads to significantly higher drag.
- Buoyancy: Objects immersed in water experience reduced gravity, assisting with movement and reducing stress on joints.
Hydrodynamics
- Consists of:
- Streamline (Laminar Flow): Fluid flows smoothly without crossovers.
- Turbulent Flow: Erratic movement of fluid in swirling patterns, leading to greater resistance; movement creates its own turbulence.
- Movement against turbulent water increases resistance, contrasting with movement through still water.
