Aquatic
Therapy:
Aquatic Therapy is an effective treatment
modality for patients who are unable, or
unready to perform land-based physical
therapy. The unweighting of painful joints
(see buoyancy below) can help your PT
address a multitude of conditions and
diseases. For instance, patients with
osteoarthritis and spondylosis can tolerate
many more movements in the water than on
land.

Applications: Some physicians
use aquatic therapy as part of their post
surgical protocol, including conditions such
as spinal surgery and joint replacement.
Other doctors, such as an OBGYN, use aquatic
therapy for pregnant women looking to
alleviate back pain. The benefits of aquatic
therapy are far reaching and are
increasingly supported by uncounted case
studies.
Heat (91-94°F): The warmth of the water assists
the body by relaxing muscles while
increasing blood flow to the injured areas.
Hydrostatic Pressure:
A perpendicular force is
applied once the water surrounds the body.
This ultimately allows for better blood
circulation which can result in a reduction
of swelling and joint tenderness. In
addition, range of motion and proprioception
can also improve.
Buoyancy:
On land, gravity is the major
force pushing on our bodies. While submerged
in water, buoyancy assists in supporting
body weight, countering the effects of
gravity. These effects include the
translation of weight through painful and/or
arthritic joints. By reducing these forces
on the involved joints, you are able to
perform many activities that you may have
otherwise avoided due to pain.
Water Resistance: The natural
resistance of the water allows for muscle
strengthening without the need for weights.
Because there is no negative phase on each
repetition, there are less stresses
translated through the joint. You will
experience improvement in balance and
strength with all muscle groups exercised.
Musculoskeletal
Benefits of Aquatic Therapy:
-
Buoyancy and
hydrostatic pressure cause the central
return of lymph and compression of soft
tissues, which mobilizes extracellular
fluid.
-
Bed rest is
not always the answer to painful
symptoms. Immersion during therapy can
rapidly reduce edema and has the
additional benefits intrinsic to
exercise.
-
Blood supply
to muscles is increased. This improves
oxygen delivery to muscles and improves
removal of muscle lactate and other
metabolic end products.
-
Increased
muscle relaxation due to improved blood
supply, neutral warmth of water and
decreased sympathetic nervous system
activity.
-
Some
inhibition of spastic muscles probably
because of decreased gamma fiber
activity, which decreases muscle spindle
activity.
-
Decreased
joint compression forces.
-
Prepares
soft tissue for mobilization.
