Physiotherapy in sporting dogs : Physiotherapy in sporting dogs Prof. Dominique GRANDJEAN DVM, PhD, HDR Unité de Médecine de l’Elevage et du Sport Ecole Nationale Vétérinaire d’Alfort France What is physiotherapy ? : What is physiotherapy ? Non invasive physical methodologies helping the treatment of disease or trauma Physiological benefits include  Reduction of muscle atrophy  Earlier resolution of inflammation  Improved joint hemostasis and biomechanics  Promotion of wound healing  Earlier functional return Physiotherapy methodologies : Physiotherapy methodologies  Passive range of motion  Massage  Controlled exercise  Cold and heat  Electrostimulation  Ultrasound  Laser  Electromagnetic therapy  Magnetic field therapy  Faradism …  Nutrition Therapeutic ultrasound : Therapeutic ultrasound Ultra sound Diagnosis [imaging of internal structures] Tissue destruction [surgery for tumor irradiation] Physical therapy [Deep tissue healing ; joints function restoration ] Therapeutic ultrasound : Therapeutic ultrasound Physical principles Heat 4 to 6 cm deep in tissues Compression Rarefaction Therapeutic ultrasound : Therapeutic ultrasound Physical principles Heat Ultrasound absorption by proteins  Healing  Beware : bones  pain Therapeutic ultrasound : Therapeutic ultrasound Physical principles Ultrasound wave Rarefaction Compression [Areas of decreased density and pressure] Air bubbles in blood and tissues Enter of gas in the bubbles Gas flows out of bubbles Compression Gas exchange Mechanical stress Increased chemical activity Therapeutic ultrasound : Therapeutic ultrasound Therapeutic effects 1. Increase in range of motion Facilitates stretching exercises vs stiffness and decrease in flexibility  Preheating of periarticular connective tissues Reduces size of scars (<3 months old)  Lenght of time between injury and onset of treatment increases less satisfactory results 2. Decrease in pain and muscle spasm Still unexplained effects on nerve fiber conduction  Post-operative scars (1.5Wcm-2/6 min)  Back muscles pain (0.5Wcm-2/12 min) Therapeutic ultrasound : Therapeutic ultrasound 3. Calcium deposits Stimulates resorption of calcium deposits  vs exostosis 4. Wound healing Acoustic streaming seems to play a role in tissue repair [skin temperature rise too small] Very efficient on tendons if applied at low intensities two weeks after injury / surgery Therapeutic effects Therapeutic ultrasound : Therapeutic ultrasound  Equipments .

Bacterial infections . Rapid growth tissues  Tumors  Fetuses Massage : Aims  Increase local circulation  Eliminate an exsudate  Stretch the matrix of collagen fibers of a scar  Increase muscular relaxation  Allow other exercises to begin more calmly Massage Massage : Massage Indications  Race warm-up/recovery  Limit and reduce adhesion under a scar  Maintain a maximum degree of articular mobility  Reduce muscle stiffness / contractures Massage : Massage Different methods of massage 1/ Effleurage  Effective to reduce swelling  Sedative effect Large movements Damages vein valves Massage : Massage Different methods of massage 2/ Petrissage . Small movements concentrated on one zone . Muscular body gradually pinpointed and relaxed  Improves circulation in deep zones  Effective on contractures Massage : Massage Different methods of massage 3/ Friction . Other type of deep massage . Performed along scars or accross muscle fibers  Elimination of scar tissues  Promotion of healing  Reestablishment of full mobility of a joint Massage : Massage Chronology Massage can start on the day of injury / surgery  continue throughout the rehabilitation period Massage : Massage Danger No massage when facing an acute muscle lesion  partial rupture  hematoma Mobilization : Mobilization Passive range of motion P.R.O.M. Active range of motion A.R.O.M. Passive range of motion : Passive range of motion . Manipulation that consists of mobilizing a joint through and beyoung its normal range of motion . Muscles need to be relaxed  contractures . Movement must be performed slowly Passive range of motion : Passive range of motion Aims . Maintain or increase the range of motion in one or more injured joints . Avoid formation of undesired connect tissue Methods . Slowly bring the joint to the limit of its range of motion . Hold in place for a few minutes . Bring to a new range of motion  10 to 15 movements / 3 times per day Contraindications . Unstable fracture sites . Luxations . Hypermobile joints Active range of motion : Active range of motion Active exercises  Obedience exercises [« sit », « down », « up », « stay »]  Exercises involving muscular resistance . Gradually increase weight supported by affected limb . Walking, trotting,weight-pulling, weight-bearing  Hydrotherapy [swimming] .
