18 Questions
What is the significance of drag in the context of movement through water?
As the speed of movement through water increases, resistance to movement increases.
What is the clinical significance of specific heat in water?
Water retains heat 1000 times more than air.
What is the center of buoyancy, and what is its significance in aquatic therapy?
It is the reference point of an immersed object on which buoyant vertical forces of fluid predictably act.
How does the principle of whirlpool bath therapy work?
It combines the effect of temperature with the mechanical effect of the water.
What is the effect of unilateral lower limb amputation on the center of buoyancy in a patient in a whirlpool bath?
The patient will lean towards the residual limb side.
What is the purpose of the stainless steel tanks in whirlpool bath therapy?
They are used to accommodate one limb or multiple limbs, depending on the size of the tank.
What is the clinical significance of buoyancy in hydrotherapy?
Buoyancy provides the patient with relative weightlessness and joint unloading, allowing performance of active motion with increased ease.
What is the primary purpose of monitoring temperature during hydrotherapy?
To avoid applying very hot or cold water to aged, weak, or children patients.
What is the concept that describes the upward thrust experienced by an immersed body equal to the volume of liquid displaced?
Archimedes' principle
What is the primary benefit of hydrotherapy in terms of muscle relaxation and fatigue relief?
It relieves fatigue and produces relaxation in muscles.
What is the primary purpose of hydrostatic pressure in hydrotherapy?
It exerts pressure on immersed objects.
What is the significance of center of buoyancy in hydrotherapy?
It is a property of water that contributes to the therapeutic effects of hydrotherapy.
How does radiation play a role in heat transfer during water therapy?
Radiation assists in the transfer of heat from the skin to the air.
What is the purpose of using inflatable cervical collars in water therapy?
To support the neck and maintain the head out of the water for supine patients.
How do flotation rings contribute to the effectiveness of water therapy?
They support the extremities in any immersed position, often at wrists and ankles.
What is the primary function of buoyancy belts in water therapy?
To position patients supine, prone, or vertically for shallow and deep water activities.
How do gloves, hand paddles, and hydro-tone balls increase resistance in water therapy?
By applying resistance to upper extremity movements, increasing drag and effort required.
What is the role of fins and hydro-tone boots in water therapy?
To generate resistance by increasing the surface area moving through the water during lower extremity motions.
