Relaxation Training and Aquatic Exercise Flashcards
Jacobson’s progressive relaxation technique includes
a systematic distal to proximal progression of conscious contraction and relaxation of musculature
Buoyancy
The upward force of water on an immersed or partially immersed body or body part
Cohesion
The tendency of water molecules to adhere to each other
Resistance encountered while moving through water is due to cohesion - some force is needed to separate water molecules
Density
the mass per unit volume of a substance
Density of water is proportional to its depth
Hydrostatic pressure
the circumferential water pressure exerted on an immersed body part
A pressure gradient is established between the surface water and the deeper water due to inc density in deeper water
Hydrostatic pressure - Pascals law states that
the pressure exerted on an immersed body part is equal on all surfaces
Hydrostatic pressure - increased pressure counteracts
effusion and edema
enhances peripheral blood flow
Turbulence
movement of a body part through water creates a circular motion of the water near the surface of the part, producing frictional drag
Thermodynamics - cooler temp used for
higher intensity exercise
Thermodynamics - warmer temp used for
enhance mobility, flexibility, and relaxation
Thermodynamics - at temps more than 37 C (98.5 F) patients have
inc cardiovascular demands at rest and with exercise
Thermodynamics - at temps less than 25 C (77 F) patients have
difficulty maintaining core temp
Equipment - Buoyancy assistance devices
Inflatable cervical collar, flotation rings, buoyancy belt or vest, kickboard
Contraindications to aquatic therapy
B/B incontinence Kidney disease Epilepsy Severe cardiac or resp dysfunction Severe PVD Large open wounds, infections, colostomy Bleeding or hemorrhage Water and airborne infections
