INTRODUCTION

Therapeutic techniques and modalities

Therapy can start immediately after surgery using passive techniques (cold packs, electrostimulation, passive kinesiotherapy) and gradually move to active techniques depending on the speed of recovery (fig. 5).

[

Figure 5. Use of electrostimulation for analgesia.

There are two types of rehabilitation techniques: passive and active. ■■ Passive therapies (performed by the therapist) include the application of hot/cold packs, passive kinesiotherapy (joint movement), stretching, massage, electrostimulation, therapeutic ultrasound, pulsed shortwave therapy, laser, electromagnetism and hydrotherapy (fig. 6). ■■ Active therapies (performed by the patient under guidance) include active kinesiotherapy and exercises aimed at the recovery and improvement of strength, endurance, range of motion, proprioception, coordination and balance (fig. 7).

Passive therapies ■■ Application of hot or cold packs. ■■ Passive kinesiotherapy.

The therapist should have a good knowledge of certain basic concepts of veterinary medicine, such as: ■■ Anatomy. ■■ Biomechanics and exercise physiology. ■■ Pathophysiology of the lesion/inflammation. ■■ Musculoskeletal tissue response to disuse and subsequent mobilisation. ■■ Healing and functional recovery of the various tissues. ■■ Functional neurology. If the therapist is a veterinary surgeon, he or she will be able to reach a diagnosis, set objectives, draw up a treatment plan and give a prognosis. If the therapist is a veterinary nurse/technician or a qualified human physiotherapist, he or she should always apply the techniques under the supervision of a veterinary surgeon who will be responsible for the case.

■■ Stretching and traction. ■■ Massage. ■■ Electrostimulation. ■■ Ultrasound. ■■ Shortwave therapy. ■■ Laser. ■■ Magnotherapy.

Active therapies ■■ Active assisted kinesiotherapy. ■■ Active resistance kinesiotherapy. ■■ Active kinesiotherapy. ■■ Hydrotherapy.

EXERCISE PHYSIOLOGY

Flexibility and mobility Physical fitness is based on four factors:

These can be defined as “the ability to move a joint through its full range of motion”.

COMPONENTS OF PHYSICAL FITNESS

Flexibility and mobility can be restricted by any of the following factors: ■■ Muscle contractures, scars, shortened ligaments. ■■ Joint incongruence or altered biomechanics. ■■ Inflammation, oedema, effusion, adhesions or fibrosis.

■■ Cardiovascular endurance. ■■ Flexibility. ■■ Muscle strength. ■■ Muscular endurance.

Passive kinesiotherapy and stretching are used to help soft tissues recover their normal length and function and to prevent contractures and subsequent lesions (fig. 2) (see chapter on Kinesiotherapy and stretching).

Cardiovascular endurance Cardiovascular endurance is defined as “the capacity of the heart, lungs and blood vessels to carry oxygen to the muscles during activity”. To build up endurance, an exercise plan should include low-intensity, longduration exercises with little static muscle contraction (e.g. jogging rather than sprinting). This implies aerobic and endurance exercises (fig. 1).

THERAPEUTIC MASSAGE

Types of massage

Effleurage Although there are several kinds of effleurage, including stroking, this section will only describe lymphatic drainage massage (fig. 4). This massage consists of moderate-pressure strokes in a centripetal direction (towards the heart), using the palm of the hand and keeping the fingers together. It is usually applied from the most distal part of the extremities towards the trunk.

A wide range of massage techniques is available, each with its advantages and disadvantages, its indications and contraindications. There is no best technique: the therapist should make a coherent choice based on the lesion, the patient and his/her own skills. In the next section, some of the most commonly used techniques in veterinary rehabilitation are described.

The effect of the drainage technique is an increase in blood and lymph flow, which makes it particularly suitable for the treatment of, for instance, distal oedema.

Stroking This is a gentle massage that consists of rhythmic continuous strokes in a centrifugal direction (in the direction of the hair growth) using the palm of the hand with the fingers held together; contact with the patient is never lost (fig. 3). It is a superficial massage that produces a relaxing effect in the patient, thus preparing it for further manipulation. It also increases blood flow and stimulates lymph flow. This massage is commonly used to start and end a session, although it can also be used during a session. Stroking is useful to calm a patient after a massage of the deeper tissues.

Kneading or petrissage Kneading is a type of deep massage that should be applied to a relaxed animal, which means that it should be preceded by both aforementioned massage types. It consists of grasping a fold of skin, subcutaneous tissue or muscle (depending on the depth), then releasing it, and moving on to the next area (fig. 5). The movement of the hands is similar to kneading dough. It may be started in the most distal areas of the body and advance in a proximal direction. This massage is applied both parallel and perpendicular to the fibres. Previous

Classification of electrical therapies According to the type of current

Direct current: galvanic and faradic.

ELECTRICAL STIMULATION

[

Figure 4. Device for the application of electric currents with variable parameters.

Alternating current: low frequency, interferential (medium frequency), shortwave and microwave (high frequency). Electrochemical (ionic changes): galvanic.

According to the physiological effect

Electrokinetic (muscle contraction): low-frequency alternating, galvanic and interferential current. Thermal: short wave and microwave (high frequency).

Physiological effects Sensory or motor nerve fibres can be stimulated, depending on the type of therapy and the parameters used (fig. 4). 1] Motor stimulation (muscle contraction without joint movement) will help to obtain (fig. 5): ■■ Muscle strengthening. ■■ Increased muscle tone. ■■ Decreased muscle spasms. ■■ Increased venous circulation. ■■ Increased lymphatic and arterial flow. ■■ Prevention of adhesions. ■■ Stretching of fibrotic tissue. ■■ Improved quality of the connective tissue (collagen alignment).

[

Figure 5. EMS. Application of electrodes over the origin and insertion of the gluteal muscle.

2] Sensory stimulation (analgesia): ■■ Via the spinal gating mechanism (stimulates the production of enkephalins in the dorsal spinal horn). ■■ Through the production of endorphins. ■■ By stimulation of the descending inhibitory pathways (serotonin pathway).

General indications and objectives for electrical stimulation ■■ Muscle contraction: both innervated and denervated muscles. ■■ Analgesia. ■■ Myofascial pain syndrome (trigger points). ■■ Passive congestion. ■■ Consolidation and fibrosis (healing).

OSTEOARTHRITIS

OWNERS OFTEN NOTE THAT THEIR PET:

Radiography is the most common diagnostic tool in veterinary practice. Radiographic signs that can be found in a joint with any degree of OA include (figs. 4, 5 and 6): ■■ Degeneration of the joint cartilage. ■■ Formation of osteophytes. ■■ Bone remodelling. ■■ Periarticular changes. ■■ Synovial effusion.

■■ Has difficulty getting up. ■■ Shows increased lameness when it is cold. ■■ Has difficulty climbing up and/or down stairs and ramps. ■■ Has a slower and stiffer gait than before. ■■ Is less active (plays less, sleeps more).

For the diagnosis of OA, in addition to the history, a complete physical and orthopaedic examination is required (fig. 2 and 3); further investigations may be carried out, such as radiography, synovial fluid analysis, ultrasonography, MRIs or CT scans.
