  1. HYDROTHERAPYLECTURE 1 INTRODUCTION TO HYDROTHERAPY Hydrotherapy as a modality for rehabilitation has a long history and is as important today as it was in the past. Physiotherapists are encouraged to use water, making the most of its unique properties .Hydrotherapeutic techniques must be learnt and new ideas explored and developed.

  2. The word hydrotherapy is derived from the Greek words hydro (water) and therapeia (healing). Hydrotherapy is as old as history of mankind, and information on activity in water for both therapeutic and recreational purposes has been documented.

  3. New knowledge regarding the physiology of hydrotherapy and new techniques using patterns of movement adapted to water and more specific water-exercises are ensuring that hydrotherapy is becoming increasingly accepted as a medium for rehabilitation.

  4. LECTURE3 :-ASSESSMENT AND RECORDINGBiophysical Effects of Hydrotherapy:- A- THERMAL EFFECTS: The effect of hydrotherapy is to gain the therapeutic value of heat or cold. The same physiologic of heat and cold apply to hydrotherapy as to other thermal agents, except that a larger body surface area usually is immersed in water than that covered by a hot or cold pack. Therefore, exposure of the body to varying temperatures will have not only a local effect, but also systemic effects on the cardiovascular and other organ systems.The greater the difference in temperature between, and blood pressure is raised, as a result of peripheral vasoconstricition.The increase in peripheral resistance requires the heart to work harder to maintain adequate blood flow the periphery.

  5. The application of heat to the entire body will cause an initial increase in blood pressure, followed by a decrease in blood pressure as a result of vasodilatation.The initial rise in blood pressure may be quite marked and prolonged if the temperature of the bath is very high, above 40 c . Respiratory rate will increase with the application of heat or cold, although the increase may be less marked with the application of heat.

  6. B- MECHNICAL EFFECTS: The three main mechanical effects of water are:- 1- Buoynacy :-This is the capacity of that water to support objects in it. Buonacy may be affected by (1) Postural alingment ,(2) The surface area immersed , (3)The weight of the bones in relation to muscle and fat, and (4) Vital capacity . 2- Cohesion and Viscosity:- Water molecules are cohesive, they have the the ability to attract each other. Cohesion in a liquied is the attractive force exerted by each molecule on those surrounding it. This wil cause resistance to any object moving through the liquid. The greater the cohesion of the molecules, the greater the viscosity of the liquid.

  7. HYDROTHERAPYLECTURE 5 TECHNIQUES OF EX. IN WATER AND THERAPEUTIC SWIMMING Hydrogymnastics as a systematic form of ex. In water begain in the early part of the twentieth century.The uniqueness of water lies mainly in the presence of buoyancy. Buoyancy supports the body and diminishes the effects of gravity. An advantage accouring from that it induces relaxation and relieves pain more than on the ground where the weightlessness allows a greater freedom of movements. Other factors are cohesion, viscosity, turbulence and friction.

  8. Therapeutic Effects Of Ex. In Water:- The therapeutic effects of ex. In water have been well documented.It is recognised that an increase in muscle power and endurance, the mobilizing of joints, the reduction of spasticity, relaxation, improvements in balance and coordination, functional activity and recreation are among the most important of these effects.

  9. Techniques Of Ex. In Water:- There are a number of techniques of ex. In water available to the Ph.Th. These include :- *Buoyancy assisted, supportd, resisted, ex. *Bad Ragaz patterns. *Hold- relax techniques. *Stabilizations. *Repeated contractions. *Breathing ex. *Spinal mobilizations. *Hydrodynamic ex.

  10. LECTURE 2:-THE PHYSIOLOGICAL, THERAPEUTIC AND PSYCHOLOGICAL EFFECTS OF ACTIVITY IN WATER The uniqueness of water lies mainly in its buoyancy, which relieves stress on weight bearing joints and permits movements to take place with reduced gravitational forces, thus non- weight- bearing activities can be commenced before they are possible on land. The physiological effects of ex. Combined with those brought about by the warmth of water are one of the advantages of activity in this medium.

  11. The therapeutic effects of ex. In water relate to:- 1- The relief of pain muscle spasm. 2- The maintenance or increase in range of motion of joints. 3- The strengthening of weak muscles and an increase in their tolerance to ex. 4- The re- education of paralyzed muscles. 5- The improvement of the circulation. 6- The encouragement of functional activities. 7- The maintenance and improvement of balance, co- ordination and posture. 8- The improvement of gait pattern.

  12. In addition, water provides the potential for ex. In water in three dimensions which cannot be achieved on land. There is the possibility of considerable perceptual stimulation:- A - Visually. B – Aurally. C – Via the skin propriocepors. D - By heat.
