Canine Hydrotherapy, Underwater Treadmill verses Swimming

Hydrotherapy for Dogs

What is Hydrotherapy?

Hydrotherapy is a water-based therapy that provides prescriptive exercise which is functional without being painful. It can be used as a means of supporting dogs in a non weight bearing or partially weight bearing environment to allow movements that would not be possible on land, perhaps because of weakness or injury. To facilitate rehabilitation and conditioning, hydrotherapy uses key water properties, including:

Buoyancy: reduces the weight and concussion going through the limbs and makes movement easier

Hydrostatic Pressure: increases circulation and reduces inflammation, swelling and pain

Resistance: assists in restoring muscle strength, endurance, and cardiovascular fitness

Turbulence: the movement of the water which can create a more challenging environment – ideal for fitness patients.

Specific gravity: The ratio of body weight compared to the ratio of water; this helps with buoyancy.

Temperature: The warmth of the water helps in reducing swelling, inflammation, and pain, increasing blood flow, reducing muscle tension and spasms, increasing tissue extensibility, and promoting relaxation.

Underwater Treadmill Versus Swimming

Hydrotherapy typically involves either swimming in a pool or exercising on an underwater treadmill (UWTM). Both of which can be effective for increasing strength, joint range of motion, muscular endurance, cardiovascular endurance, and flexibility as well as reducing pain and effusion, and promoting psychological well-being. The decision about whether an UWTM or pool is most suitable for your dog is an important one that should be made on a case-by-case basis by a qualified Veterinary Physiotherapist or Hydrotherapist. Here are a few reasons why we may recommend one over the other:

Advantages: Underwater Treadmill

·         Allows for earlier rehabilitation following injury or surgery

·         Ideal for gait training and speeding up gait retraining – particularly useful for neurological patients to help with gait patterning with the support of the water. Interestingly, many neurological patients walk in water before they do on land.

·         Improved balance whilst walking

·         More suitable for certain clinical conditions and injuries that require more controlled movement versus swimming.

·         Ideal for dogs that are nervous about swimming – dogs often feel more relaxed when they can touch the floor so are less likely to panic

·         More natural gait pattern

·         Joint extension is more complete compared to swimming. This can be helpful in conditions such as hip dysplasia or hip arthritis whereby limb extension is often difficult for the dog.

·         Encourages equal weight bearing

·         Functional carry over to land is often quicker

·         The water height can be adjusted to decrease/increase weight bearing and achieve movements and muscle activation that we are targeting

·         Based on Wolf’s Law, weight bearing on the UWTM may encourage increased bone strength over swimming alone.

·         Allows observation from all sides

·         We can be more hands on to aid the dog’s gait and movement patterns

·         Speed, incline, and duration can be adjusted to suit the dog

·         More targeted muscle development

Disadvantages: Underwater Treadmill

·         Can strengthen gait abnormalities if not properly corrected by the Hydrotherapist

·         Not as suitable for amputees

·         Some dogs may be unsure about the movement of the belt or being confined in a smallish space

·         The retraction of the belt may cause too much strain on certain tissues if the Hydrotherapist does not provide appropriate support

Advantages: Swimming

·         Enables the dog to be completely non weight bearing - this removes all the forces and concussion through the joints which is useful when weight bearing is painful.

·         Great for core strengthening

·         Greater cardiovascular strengthening, weight loss and increasing overall fitness

·         Potentially more suitable for amputees and dogs unable to bear any weight of their own

 Disadvantages: Swimming

·         Not suitable for fearful or nervous swimmers

·         Unsuitable for many injuries in the early stages of rehabilitation. For example, in dogs who have recently had surgery for a cranial cruciate ligament injury, swimming could place too much twisting, torque and pressure through the joint and potentially lead to further damage.

·         Not as effective for improving joint extension

·         Can cause dogs to hollow through the neck and back causing too much strain on these areas

 Most dogs will benefit greatly from hydrotherapy; however, remember it is not a stand-alone treatment and should always be combined with physiotherapy and lifestyle/environmental changes. Lastly, always get advice from your Veterinary Surgeon before taking your animal for treatment.
