Physiological effect of hydrotherapy BY Dr. Shereen M. Said Lecturer of physical therapy MUST  Physiological effect of hydrotherapy 1-cardiovascular system -increase venous return secondary to hydrostatic pressure -increase atrial pressure -Increase cardiac out put, it increases to 8.6 L/min at 86 bpm., stroke volume - Decrease systemic vascular resistance  2-Pulmonary system 1-rib cage circumference decrease to about 10% by hydrostatic pressure 2-vital capacity decrease 6-9% 3- pulmonary blood flow increase 4-total work of breathing increase by 60%with water to the level of the neck. 3-renal system: -increase of creatinine clearance, sodium excretion, potassium excretion due to increase blood flow thus increases diuresis. -Hydrotherapy with full-body immersion has been recommended as a treatment for edema in patients with nephrotic syndrome and cirrhosis. 4- musculoskeletal system: -increase resting blood flow by 100%to 225% -increase blood flow and oxygen of muscle -remove waste products -increase elasticity of the muscle -due to bouncy there less load on the joint - Due to velocity water can be used to provide resistance from previous we can discover the effect of thermotherapy and cold therapy 1- effect of thermotherapy -relieve pain -increase elasticity of the muscle -give relaxation -hyperemia effect due to increase blood flow so increase metabolites rate so give more heat 2-effect of cooling therapy -decrease metabolic rate so decrease metabolites -decrease heat -reduce pain -local vasoconstriction -decrease cellular metabolism so decrease edema -cooling more depth in tissue N.B application of cooling therapy after any trauma at least 72 hours Therapeutic uses of hydro therapy 1- vasodilation or vasoconstriction 2- wound care (not opened ) 3-water exercise 4- pain control 5- edema control due to hydrostatic pressure and change in renal function ⚫ Indications of Hydrotherapy ⚫ Subacute/chronic soft tissue injury ⚫ Muscle contractures ⚫ Scar formation ⚫ Osteoarthritis ⚫ Subacute/chronic rheumatoid arthritis ⚫ Patients who are post fracture ⚫ Open wounds ⚫ Burns with intact thermal sensation ⚫ Pressure ulcers. ⚫ Muscle spasm. ⚫ Tension ⚫ Anxiety ⚫ Muscle weakness from disuse ⚫ Muscle weakness from central nervous system (hemiplagia) ⚫ Peripheral nervous system pathology (polyneyropathy). ⚫ Contraindications to Hydrotherapy – Cardiac dysfunction – Infectious diseases/fever – Vomiting – Urinary infections – Suprapubic catheter – Severe burns if altered or impaired thermal sensation – Bowel or bladder incontinence – Respiratory dysfunction – Severe peripheral vascular disease – Bleeding disorders – Impaired/decreased thermal sensation – Atopic eczema – Acute rheumatoid arthritis.  Precautions for Hydrotherapy – Hypersensitivity to chemicals used in pool – Multiple sclerosis (water warmer than 88° is not appropriate) – Thermoregulatory problems. – Epilepsy ⚫ --Excessive fear of water – Peripheral vascular disease – Fever – Compromised respiratory function – Unstable high or low blood pressure – Severely weakened or deconditioned state.
