Title: Rehabilitation of Athletic Injuries


1
Rehabilitation of Athletic Injuries
  • Aquatic Therapy

2
Benefits of Aquatic Therapy
  • Buoyancy
  • Depth
  • Hydrostatic Pressure
  • Viscosity
  • Temperature

3
Buoyancy
  • Buoyancy assists, supports, OR resists extremity
    movement.
  • Archimedes Principle any object submerged or
    floating in water is buoyed upward by a
    counterforce that helps support the submerged or
    partially submerged object against the downward
    pull of gravity.

4
Buoyancy
  • In other words
  • Buoyant force assists motion toward the waters
    surface and resists motion away from the surface.
    This allows
  • An athlete weighting 200 lbs. when submerged
    displaces nearly 95 of their body weight.

5
Water Depth
  • Depending on the depth of the water
  • Deeper water decreases the bodys weight on/to
    an extremity.
  • Less water increases the bodys weight on/to
    an extremity.

6
Water Depth
  • An athlete standing in chest-deep water will only
    weight 30 to 40 of their body weight.
  • Majority of males body weight is in the upper
    trunk and upper extremities.
  • Majority of female body weight is in the lower
    abdomen and lower extremities.

7
Hydrostatic Pressure
  • Assists in controlling edema in the extremities.

8
Viscosity
  • Make-up of the water and the forces that provide
    resistance

9
Viscosity
  • Factors that provide resistance to movement
  • Make-up of the water molecules
  • Type of water
  • Salt/Fresh

10
Temperature
  • Water that is at or below body temperature
    acts as a means of preventing heat illness.

11
Forces that Provide Resistance
  • Cohesive Force
  • Bow Force
  • Drag Force

12
Cohesive Force
The cohesive molecules of the water that are
bound together.
object
movement
Surface of the water
13
Cohesive Force
As an object moves through the water, resistance
is provided the type of water molecules the
object encounters.
14
Bow Force
A force that is generated at the front of the
object during the movement.
Bow Force
15
Bow Force
Increase in water pressure at the front of the
object.
Bow Force
16
Drag Force
The backward force created by turbuences from the
bow force.
17
Drag Force
  • As the forward motion of the body/object creates
    turbulence or eddies, there are small whirlpools
    created as the water moves from areas of high
    pressure (the bow) to areas of low pressure

High Pressure
Area of Low Pressure
Forward Motion
Area of Low Pressure
High Pressure
18
Drag Force
  • This is important to aquatic therapy.
  • the drag force on an object can be controlled
    by changing the shape of the object or the speed
    of its movement.
  • This means that the more streamlined an object,
    the less bow force is generated, the less the
    drag.

19
Drag Force
  • This means if we have an athlete reduce his bow
    force, (use of the hands to streamline the bodys
    motion in the water) we can reduce drag force.
  • The athlete doesnt have to work as hard!!!!!!

20
Drag Force
  • To decrease the resistance for a weak athlete,
    movements should be done slowly and in a
    streamlined position.
  • To increase resistance, movements should be done
    faster and in a non-streamlined position.

Advantages of Aquatic Therapy
  • Exercises in water are more easier to perform
    than on land
  • Weight bearing activities in water allow for
    better control by athlete
  • Weight bearing activities can begin sooner in
    water than on land

24
Advantages of Aquatic Therapy
  • By applying Archimedes Principle you can
    gradually increase the amount of weight bearing.
    Athletes in neck deep water are only bearing
    approx. 50 of TBW.
  • Warm water encourages increased ROM
  • Water provides a medium for accommodating
    resistance- muscles are stressed gradually over a
    period of time.

25
Advantages of Aquatic Therapy
  • Increases athletes confidence in their ability
    to perform simple tasks.
  • Energy is burned up four times faster than in
    land based activities (High calorie burn up).

26
Disadvantages
  • Cost of maintaining a rehab pool facility
  • Patients require more stabilization in water and
    may need more supervision.
  • Open wounds/Sores may be contraindicated for
    aquatic therapy. (spreading infection to other
    athletes.
  • Excessive fear of the water by the patient.

27
Disadvantages
  • You may have to get in pool w/ patient
  • Other
  • Fever
  • Urinary tract infections
  • Allergies to pool chemicals
  • Cardiac problems
  • History of uncontrolled seizures

28
Tools for Aquatic Therapy
  • Kickboard
  • Fins
  • Pull buoys
  • Paddles
  • Wet Vest
  • Rescue tube
  • Milk Containers (Jugs)

29
Aquatic Therapy
  • Should never replace traditional land based
    exercise programs.

30
Summary
  • Aquatic therapy allows the athlete to exercise in
    a reduced stress (non-weight baring) environment.
  • Aquatic therapy is meant to complement and not
    replace traditional land-based rehabilitation
    exercise programs.

31
Techniques of Aquatic Therapy
  • HOMEWORK ASSIGNMENT Look up the two terms below
    in your Prentice text.
  • Be able to describe them in LAB
  • Buoyuancy Technique
  • Bad Ragaz Technique
