Veterinary rehabilitation has evolved beyond traditional physical therapy. Today, PulseVet® shock wave therapy and Assisi LOOP® targeted pulsed electromagnetic field (tPEMF™) therapy provide evidence-based alternatives for chronic tendinopathies, osteoarthritis, and post-operative recovery.
These non-invasive modalities offer repeatable, well-tolerated interventions with objective outcome data—transforming treatment for cases where surgery carries excessive risk or owners seek conservative management.
What Is Shock Wave Therapy for Dogs?
Shock wave therapy delivers high-velocity acoustic waves that penetrate deep tissues to stimulate cellular healing. Originally developed for kidney stone treatment in humans, the technology now addresses chronic musculoskeletal conditions in veterinary patients.
Therapeutic effects include:
- Increased regional blood flow and angiogenesis
- Upregulation of growth factors (VEGF, TGF-β, BMP)
- Mechanical disruption of calcifications and fibrotic tissue
- Reduction of inflammatory mediators
- Accelerated tissue healing
Focused vs. Radial Shock Wave: Critical Differences
Focused Extracorporeal Shock Wave Therapy (ESWT) offers superior veterinary applications:
- Adjustable penetration depth (5-40mm+) for anatomical precision
- Targeted wave pattern for specific tissue planes
- 90%+ of patients tolerate awake treatment
- Patient feedback identifies exact pain localization
- Minimal noise and discomfort
Radial Pressure Wave Therapy has significant limitations:
- Cannot target specific tissue depths
- Strongest at skin surface with diverging pattern
- Louder operation requiring ear protection
- More painful for patients
- Less common in veterinary practice
Bottom line: Focused ESWT provides targeted electromagnetic pulses and keeps patients comfortable, resulting in optimal clinical outcomes.
PulseVet® Therapy: Modern Focused Technology
The PulseVet® shock wave XTrode™ system addresses limitations that previously made shock wave therapy challenging:
Key features:
- Electrohydraulic technology with broad focal zone
- Energy and pulse controls on handpiece (no foot pedals)
- Minimal acoustic amplitude and noise
- 3-5 minute treatment sessions
- 90%+ patient tolerance while awake
Clinical advantages:
- Real-time patient feedback enables precise targeting
- Equal or superior outcomes versus older sedation-requiring systems
- Improved scheduling efficiency and client acceptance
- Dogs naturally indicate exact pathology location through response
Treatment technique: Apply generous coupling gel, part hair (clipping usually unnecessary), position probe perpendicular to tissue. Start at lower energy, increase until patient shows awareness, then reduce slightly for optimal comfort and targeting.
Assisi LOOP® Targeted PEMF Therapy
Assisi LOOP® tPEMF™ therapy delivers Assisi LOOP® tPEMF™ therapy delivers targeted electromagnetic pulses that work at the cellular membrane level to promote healing. Backed by decades of FDA-cleared use in human medicine since the 1970s, PEMF technology is now transforming veterinary care—accelerating post-operative recovery and providing effective chronic pain management for pets.
Therapeutic effects:
- Enhanced nitric oxide production and vasodilation
- Improved tissue oxygenation and nutrient delivery
- Upregulation of anti-inflammatory cytokines
- Accelerated wound healing
- Modulation of pain signaling pathways
Treatment options:
The portable Assisi LOOP® device positions electromagnetic coils over treatment areas for 15-minute sessions. Home therapy capability improves owner compliance. Treatment penetrates casts, bandages, and bedding without removal—a significant advantage over cold therapy.
Assisi LOOP® Lounge beds provide continuous electromagnetic field therapy during rest, examinations, and rehabilitation exercises with integrated orthopedic support.
Evidence-Based Clinical Applications: Shock Wave and Targeted PEMF Therapy
Studies demonstrating the success of both extracorporeal shock wave therapy and targeted PEMF therapy abound.
Elbow Dysplasia and Osteoarthritis
Force plate studies document objective improvements with PulseVet shock wave therapy:
- Increased peak vertical force in treated limbs
- Improved vertical impulse measurements
- Enhanced gait symmetry indices
- Sustained improvements 8-12 weeks post-treatment
Protocol: Target entire joint in three dimensions with focus on medial compartment. Deliver 500-1,000 pulses per session at energy level E3-E5. Repeat every 2-3 weeks for 2-5 treatments. Consider maintenance every 1-3 months during competition season.
Shoulder Tendinopathies
Biceps tendinopathy, supraspinatus tears, and infraspinatus calcification respond to combined ESWT, shoulder hobbles (4-6 weeks), home Assisi LOOP therapy, optional PRP, and controlled rehabilitation.
Treatment technique: Position forelimb in external rotation to expose biceps tendon. Palpate to confirm probe placement. Awake treatment allows optimal limb positioning for precise targeting.
Surgery remains indicated for complete ruptures or cases unresponsive to 4-6 treatments.
Lumbosacral Disease
Ohio State University research demonstrated statistically significant decreases in lumbosacral pain (validated by Canine Brief Pain Inventory) and lameness using deeper penetration probes (35-40mm), higher energy flux density (0.3 mJ/mm²), and bilateral paraspinal treatment.
Working dogs, service dogs, and sporting breeds with cauda equina syndrome respond particularly well, offering valuable conservative option for extending working careers.
Chronic Tendinopathies
Performance and working dogs benefit from ESWT’s ability to stimulate tissue remodeling and restore viscoelastic properties. Common applications include Achilles tendinopathy, digital flexor injuries, iliopsoas strain, and chronic biceps inflammation.
Many agility competitors benefit from monthly “tune-up” treatments during competition seasons to maintain function.
Post-Operative Recovery with Assisi LOOP Therapy
NC State University randomized controlled trial (n=16) in dogs following thoracolumbar hemilaminectomy provided Level 2 evidence:
- Improved pain pressure thresholds (p<0.05)
- Enhanced proprioceptive placing scores
- Decreased pain assessment scores
- Zero adverse effects
Animal Medical Center study found superior wound healing in Assisi LOOP therapy group (p<0.05), with controls requiring analgesics 1.8x more frequently. Additional benefits included reduced edema and earlier ambulation.
PulseVet Shock Wave Protocol
Parameters:
- Pulse count: 500-1,000 per session
- Energy level: E1-E5 (titrated to patient response)
- Penetration depth: Select probe based on target tissue (5-40mm)
- Treatment duration: 3-5 minutes per area
- Frequency: Every 2-3 weeks
- Series: 2-5 treatments for initial response
Patient preparation: Apply generous coupling gel, part hair, position for anatomical access. Most patients tolerate awake treatment.
Post-treatment: Mild soreness possible 24-48 hours. Transient lameness occasionally seen, resolves within 24 hours.
Assisi LOOP Therapy PEMF Protocol
Post-operative (acute phase): 15-minute sessions every 2 hours for 2 weeks, then twice daily for weeks 3-6. Apply over bandages/casts.
Chronic pain management: 15-minute sessions twice daily. Pre-exercise application enhances circulation; post-exercise reduces inflammation.
Owner compliance advantage: 15-minute sessions provide structured time for passive ROM and manual therapy, improving overall program adherence.

ESWT safety profile: Excellent, with reactions in <5% of patients (mild discomfort, temporary erythema, transient soreness).
Absolute contraindications:
- Active infection at treatment site
- Known neoplasia in treatment field
- Open growth plates
- Acute inflammatory phase
- Immune-mediated polyarthropathies
