W6: Aquatic exercise Flashcards
What is aquatic exercise? Why is this exercise useful? Who might benefit from this exercise?
Some of the benefits of aquatic exercise include, reduced spine and joint loading due to buoyancy, hydrostatic pressure and water temperature assisting with the balance, mobility and pain control, and suitability for people relatively restricted in the execution of land exercises.
conditions that benefit from hydro Therapy: Arthritis, Chronic pain especially lower back, fibromyalgia, MSK, post op surgery, neurological diseases (muscular dystrophy, cerebral palsy, MS, parkinsons), strokes and head injuries, and advanced osteoporosis.
What’s the benefit of aquatic exercise? Compare it with land-based exercise.
aquatic exercise can be helpful for many populations.
One being people with back or joint problems. This is due to the reduced loads applied onto these areas when under water due to buoyancy.
Hydrostatic pressure and water temperature could help with people with balance, mobility and pain control.
In general, aquatic exercises are very useful for people that have complications with executing movements on land.
To further examine the differences between land based exercise and water based exercise, one study investegated 15 exercise with the same pace and range of motion in land and water (Psycharakis et al., 2019). Results revealed that there was essentially no difference between groups. In terms of muscle activation, and perceive exertion there was similar results. However, when assessing pain frequency, intensity there was less in both for aquatic exercise group. Furthermore, Heart rate was higher on land and there was more asymmetry in muscle activation on land. The lower asymmetry in water was attributed to a more distributed load due to the similar drag forces applied in water.
When looking at which activities activated higher muscle activity and lower pain, there was higher activation of the gluteal muscle in both flexion/extension and abduction/adduction, higher activation of the back extensor muscle with or without shoulder and higher activation of the abdominal muscle when using the noodles as support. These activities also showed lower intensity of pain compared to land exercises. The implication for this is that it should be introduced in the early stages of rehab
What are the facility conditions for hydrotherapy?
~35 degrees celcius
Need to be a hoist or easy entry to the pool
How does buoyancy work?
Explain how the hydrostatic pressure
Buoyancy is an archimedes principle where the displacement of water. The buoyancy force is equivalent to the weight of the displaced water and the amount of water displaced depends on the density of the object. Some objects like the body aren’t aligned with equal weight along the weight therefore there will be a buoyancy point in which the mass will rotate. Hence this principle applies to the body when lying on the surface of water horizontally, the body would rotate until the centre of mass and centre of buoyancy align.
Hydrostatic pressure is pressure experienced under water. As there is more mass going deeper into water, more pressure exist in deeper water. By Pascal’s law the fluid pressure exerted on an object is equal in all areas of the surface. some implications of this are that people with lung problems may need to avoid hydrotherapy as it could influence the pressure in the lung. This could also mean that oedema and swelling could be reduced under water.
How could refraction affect the way a patient is performing
Because light bends in a different way compared to land, it could change the way objects or motions look from outside. therefore when assessing a patient, practitioners should be careful to not misinterpret the patients performance when looking above water.
Name some contra-indications for aquatic exercises
Cancer, CV diseases, pulmonary diseases, infections, open or draining wound, infections skin disesase, fever, inflammation, uncontrolled heart disease, uncontrolled hypertension, kidney problems, incontinence
What may be some conditions that benefit from aquatic exercises?
MSK (frozen shoulder, ankle disability), chronic pain especially lower back pain, fibromyalgia, post-surgery, arthritis (OA), Neurological diseases including parkinsons, stroke patients, advanced osteoporosis
