Aquatic Physical Therapy definition
evidence-based and skilled practice of physical therapy in an aquatic environment by a PT or by a PTA who is under the direction and supervision of a PT. Aquatic Physical Therapy includes but is not limited to:
treatment
rehabilitation
prevention
health
wellness
fitness
of patient/client populations in an aquatic environment with or without the use of assistive, adaptive, orthotic, protective, or supportive devices and equipment.
The buoyancy, support, accommodating resistance and other unique properties of the aquatic environment enhance interventions for patients/clients across the age span with what kind of disorders or conditions?
- musculoskeletal
- neuromuscular
- cardiovascular /pulmonary
- integumentary diseases,
Aquatic Physical Therapy interventions are designed to improve or maintain what?
- function
- aerobic capacity/endurance conditioning
- balance, coordination and agility
- body mechanics and postural stabilization
- flexibility
- gait and locomotion
- relaxation
- muscle strength, power and endurance
Interventions used in Aquatic Physical Therapy include, but are not limited to what mechanical modalities using the properties of water and techniques to the aquatic environment.
- therapeutic exercise
- functional training
- manual therapy
- breathing strategies
- electrotherapeutic modalities
- physical agents
Properties of Water
- Relative Density
- Temperature
- Buoyancy
- Surface Tension
- Turbulence /Streamlining
- Hydrodynamic Resistance/Viscosity
- Hydrostatic Pressure
- Hydrostatic Stability
- Refraction of light
Relative Density
Density is the mass of an object divided by what?
the volume
Relative Density
The relative density of water is what?
1
Relative Density
The relative density of the human body with the lungs inflated is between?
.95 and .974 with lungs fully inflated (will float)
Relative Density
The relative density of the human body without lungs inflated is between ?
1.050 and 1.084 without lung inflated (will sink)
Spastic muscles appear more dense
will they sink or float?
sink
Flaccid muscles appear less dense. will they sink or float?
float
Temperature of water
92-96 degrees desired for patients who are?
- less active.
Temperature of water 89-92 degrees desired for patients who are ?
moderately active.
Temperature of water 84-89 degrees desired for patients who are?
athletic.
Temperature of water Warmer temperatures help what 3 things?
- decrease tone
- promote relaxation
- assist in decreasing fear
Temperature of water Cooler temperatures help stimulate what 2 things?
tone and alertness
a force that works in the opposite direction of gravity
Buoyancy
what principle is this?
When a body is wholly or partially immersed in a fluid at rest it is acted upon by a buoyant or lifting force equal to the weight of the displaced fluid.
Archimedes’ Principle
Buoyancy Allows for the adjustment in weight bearing activities. What art the percentages o body weight reductions?
if
Waist deep water
Chest deep water
Neck deep water
50% reduction in body weight-Waist deep water
70% reduction in body weight-Chest deep water
80-90% reduction in body weight-Neck deep water
what are some general benefits using buoyancy of water?
- Acts as a supportive, assistive or resistive tool
- Helps of unload joints
- Ease in increased functional skills
- Ease of handling the client for the therapist.
- Force exerted between the surface molecules of a fluid and manifesting itself as an elastic skin of a fluid
- it nacts as a resistive force when a limb is submerged a must break it to move
- Work weak muscles under the surface of the water
Surface Tension
- the flow resistance is proportional to velocity (easy to move)
- the flow resistance is proportional to velocity squared (hard to move)
- can be used as resistance to exercise in the pool.
- The quicker the movement the greater this is
- The more unstreamlined to movement the greater the resistance to movement.
- When gait training the therapist should stand in front of the patient.
Turbulence /Streamlining
Hydrodynamic Resistance/Viscosity
Viscosity is the friction that occurs between the __________of a ____________?and causes _________to the flow of liquid.
- molecules of a liquid
- resistance
Hydrodynamic Resistance/Viscosity
Viscosity acts as a resistance to what?
movement
Hydrodynamic Resistance/Viscosity
Water provides 12 times the resistance of what
air.
Hydrodynamic Resistance/Viscosity
Can be used to progress strengthening exercises how?
- increase the surface area
- lengthen the lever arm
- increase the speed of movement.
Hydrodynamic Resistance/Viscosity
Allows more time to what?
correct for a loss
Hydrodynamic Resistance/Viscosity
Increases what kind of feedback ?
proprioceptive
pressure of a fluid (the compressive pressures exerted by molecules of a fluid upon an immersed body)
Hydrostatic Pressure
Hydrostatic Pressure
Pressure increases with what?
depth
Hydrostatic Pressure
what law states :Fluid pressure is exerted equally on all surfaces of an immersed body at rest at a given depth.
Pascal’s law:
Hydrostatic Pressure
Pressure increases 1mmHg/1.36 cm (.54”) or 88mmHg in how many feet of water?
4’ of water.
Hydrostatic Pressure
what are some benefits ?
- Builds muscles of respiration
- helps reduce edema
- helps decrease blood pooling in lower extremities.
