Medkey Pulse Therapy
$85.00

Advanced Pulse Therapy for Horses & Riders

A targeted, non-invasive therapy used for pain relief & management of hard-to-find dysfunction in horses,

where the body has fallen into chronic compensation patterns and vet scans give no answers.

Powered by German technology at Keytec, this therapy builds on SCENAR-style neuro-adaptive systems, working directly with the nervous system, not just the muscles.

How does it work?

This therapy works by interacting directly with the nervous system, using electrical impulses that continuously adjust based on the body’s response (biofeedback).

  • It stimulates nerve pathways involved in pain and movement

  • encourages the release of neuropeptides (the body’s own regulatory chemicals)

  • it interrupts persistant pain cycles

  • and reset’s the body’s internal dialogue to begin healing & recovery from the inside.

Medkey Pulse Therapy helps horses affected by:

  • chronic or unresolved pain

  • nerve-related discomfort

  • arthritis

  • tendon and ligament injuries

  • locking stifles / poor hind-end engagement

  • kissing spine

  • TMJ and poll tension

  • performance-related soreness

  • laminitis and other ongoing conditions

How this helps horses

Pain doesn’t just hurt—it changes how a horse uses its body:

  • they avoid loading certain joints or limbs

  • they overuse other areas, leading to secondary issues

  • they can’t build strength properly because they’re not using the body correctly

By helping reduce that underlying pain response, you give the horse a chance to:

  • move more evenly

  • engage the right muscles

  • actually benefit from training or rehab work

This is why it works best alongside your exercise program—not instead of it.

What’s different comparied to other therapies…

  • PEMF → delivers a general electromagnetic field over an area
    → this is targeted and responsive, adjusting moment to moment

  • TENS → fixed electrical stimulation for pain relief
    → this changes output constantly based on the body’s feedback (biofeedback loop)

  • Equissage → mechanical vibration for circulation and muscle relaxation
    → this works through neurological pathways, not just muscle stimulation


Medkey therapy works at the level of the nervous system, where pain and movement are actually controlled.

This type of neuro-adaptive therapy has been used in human settings for decades for pain and functional rehabilitation—and is now being applied to horses across the world from the UK, Europe, New Zealand and now Australia.

Currently offered exclusively by KOlsen Equine Bodywork across the Central West and Blue Mountains.

*For best results,

an initial block of 4 weekly sessions is recommended to fully intergrate the therapy and achieve long lasting results. This will depend on your horse’s individual symptoms.

$75.00

Don’t forget to look after your body too!

If you’ve returned to horses after childbirth, surgery, injury or years away from horses, you’d notice how your body doesn’t move like it used to.

Having the best trainng, tack and bodywork will only go so far for your horse if your own body is restricted in the saddle from pain.

Medkey therapy is non invasive and doesn’t interact with medication or your PT’s plan.

If you’ve been smiling throught nerve pain, tight hips & lower back, shoulder stiffness, chronic headaches or joint pain,

its time to book yourself a Rider Medkey session so you get to enjoy your horses without feeling like you’re 100 yrs old…

  • For best results - a minimum of 4 weekly sessions is recommended for your body to intergrate the changes for longer lasting relief.

Frequently Asked Questions

About Karen…

Karen is a Key Equine Therapist based in Oberon, NSW, servicing the Blue Mountains and Central West.

She works with horses experiencing movement, behaviour, or performance challenges, with a focus on improving posture, releasing muscle tension, pain relief and helping horses return to functional soundness.

Each session includes a simple, structured plan for owners to continue at home.

After a career in emergency and community health nursing, Karen developed a strong interest in equine biomechanics through working with her own horses who developed signs of body pain and soundness issues.

Frustrated by conflicting advice, she began studying equine massage & soft tissue bodywork to better understand and support horses dealing with ongoing pain and tension.

Karen gained her certification in Key/SCENAR Equine Therapy in 2025 after experiencing the benefits of this therapy herself for stubborn nerve pain. She now incorporates it into her work to support horses with issues such as chronic pain, restriction, stringhalt, kissing spine, and soft tissue injuries.

Her approach is practical, holistic and evidence based using a variety of techniques adapted help to each horse so they get the most out their sessions.

Karen is currently completing her Equine Sports Massage Certification through Equestricare Australia and has completed Equine Functional Posture Level 1 with Dr Raquel Butler.

Fully insured through IICT.
