HYDROTHERAPY
©2020 DR ROHIT BHASKAR PT HTTPS://WWW.PT-PEDIA.COM/

Hydrotherapy derived from the Greek
word hydro and therapy meaningwater
and healing
Hydrotherapy formerly called hydropathy
involves the use of water for pain relief .
Hydrotherapy is applied externally either by
immersion of the whole body or of parts of
the body in water or without immersion by
spraying or pouring water onto the body

PROPERTIES OF WATER
a) Buoyancy
b) Density
c) Hydrostatic pressure
d) Viscosity

BUOYANCY
Archimedes principle: when a
body is fully or partially
submerged in fluid at rest, it
experiences an upward thrust
equal to the wt. of fluid displaced.

BUOYANCY

RESISTANCE
If fluid is more viscous, more force is
required to create a movement
As temperature of water increases,
viscosity decreases, because molecules
move farther apart. This is beneficial for
small weak muscles.
Greater the speed of motion, higher the
resistance.

HYDROMECHANICS
Definition: Hydromechanics comprise the physical
properties and characteristics of fluid in motion
Laminar flow: Movement where all molecules
move parallel to each other, typically slow
movement.
Turbulent flow: Movement where molecules do
not move parallel to each other, typically faster
movements.
Turbulence creates an unstable environment
encouraging the core muscles of the body to
become stronger to maintain correct position and
posture.

PHYSIOLOGICAL EFFECTS
OF WATER
• Pressure
• Dissolved surfactant and
antimicrobials
Cleaning effects
• Decreased weight bearing
• Strengthening
• Slow bone density loss
Musculoskeletal
effects
• Increased venous circulation
• Increased cardiac output
• Decreases heart rate and Sys BP
Cardiovascular
effects

PHYSIOLOGICAL EFFECTS
OF WATER
• Decreases vital capacity
• Increases work load
• Decrease exercise induced asthma
Respiratory
effects
• Diuresis
• Increased sodium and potassium
excretion
Renal effects
• Relaxation
Psychological
effects

THERMOREGULATION
HR is increased
Increased cardiac output
Rise in core temperature
Muscle blood flow increased
Hot water Cold water
Slowed HR initially
HR returns to baseline in 10
min
Stroke volume increased
Cardiac output remains same

EQUIPMENTS
• Equipment used for aquatic running or
exercise-
Collars, Rings,Belts

INDICATION
❑The specific indication include
Facilitate ROM exercise
Initiate resistance training
Facilitate weight bearing activities
Facilitate CVS exercise
Minimize risk of injury and reinjury during rehab
Enhance patient relaxation
Post event recovery

APLLICATIONS OF HYDROTHERAPY
1)Orthopaedic disorders
Decreased weight bearing
Closed or open chain exercise
Velocity dependent resistance
2)Neurological disorders
Propioceptive input
Improved balance
3)Cardiac fitness
Cardiac conditioning in persons with poor tolerance to land
based exercises.

APLLICATIONS OF
HYDROTHERAPY
4)Exercise in water during pregnancy
Decreased weight bearing
Less elevation of heart rate
Decreased risk of maternal hyperthermia
5)Reducing Exercise induced asthma symptoms
Less exercise induced asthma than with other forms
of exercise.

PRECAUTIONS
Hydrophobic disorder
Neurological disorder
Seizures
Cardiac dysfunction

CONTRAINDICATION
Unstable angina and cardiac
failure Respiratory dysfunction
Severe peripheral vascular disease
Bleeding disorder
chronic kidney disease
Open wounds Uncontrolled
seizure Water or airborne
infection
Bowel and bladder incontinence
