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
- 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.

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.
