Modern science and technology have suggested incorporation of water exercises for arthritic knees due to a variety of beneficial effects, like improvement in the range of motion, muscle strengthening, increased flexibility, etc.

Commonly acknowledged benefits of aquatic therapy

Pool Exercises for Knee RehabVarious pool exercises have been proven to be beneficial, especially due to buoyancy induced low-stress environment. There are, however, a variety of benefits that have been reported as noted herewith:

  • Improved functional ability
  • Improved flexibility through working on balance, posture, swelling, and control
  • Improved muscular strength and tone
  • Improved cardiac efficiency
  • Increased sensory output

Some of the physical characteristics of water are helpful to offer multiple advantages; such as:

Water Inertia

Since water has increased resistance; easy movements in water requirethe application of more force than any other land exercises. Thus, pool exercises for knee rehab can be helpful in increasing muscle tone and strength.

Low of Acceleration

It is being identified that the acceleration potential of every move in proportion to the force applied for it is high, and is also inversely proportional to the weight of the body. Thus, the greater is the body mass, you need to apply higher force for much lesser muscular efforts.

Action and Opposite Reaction

Pool Exercises for Knee RehabAs per Newton’s third law of motion, every action is coupled with the equal and opposite reaction. The water viscosity can be helpful to either impede or assist movements. You may have noticed it multiple times that while jogging forward, your front arms come in the picture.

Water Viscosity

As per the law of viscosity, the larger surface area is always characterized by more application of resistance; on the contrary, the smaller surface area is associated with less application of resistance.

Preparation for Aquatic Therapy

Before opting for any type of pool exercises for knee rehabilitation, some of the tips shared herewith can be helpful for maximum benefits; which can be:

  • Water shoes can allow speedy traction on the pool floor
  • The water level should always be up to the waist or chest

Your strength and balance can be increased through Lag Swing

By holding the pool wall for the balance, you can stand on one leg by keeping its knee soft. The other leg is to be bent at the knee; and can be swayed in a very small range of motion, from left to right, right to left as well as front to back. Each motion can be repeated five times. Once through with one leg, switch to another.

This particular exercise is found to be helpful in improving the posture and balance. With regular implementation, people have also experienced better knee strength and pain management.
