Imagine a treatment that does not require pills or surgery but can trigger the body’s healing process with targeted sound waves. That is basically what Shockwave Therapy in Edmonton is all about: a developing physiotherapy method usually applied to manage persistent, long-term pain and soft tissue trauma.
But why is a shockwave therapeutic and not purely mechanical? The key lies in three fundamental aspects: pressure, pulse, and penetration. These variables determine wave penetration, cellular effects, and the body’s response. Understanding them helps patients and practitioners better assess the potential benefits of the treatment.
Understanding Shockwave Therapy in Physiotherapy
Shockwaves are pulses of acoustic energy that propagate at velocities greater than the speed of sound. In treatment, they are created by specific devices and administered externally to the body.
There are two primary forms used in physical therapy:
- Radial shockwaves: These diverge away from the skin surface in a spreading pattern. They are of lower energy content and have a more exhaustive area coverage.
- Focused shockwaves: These cut deeper with intensive energy at a particular point inside the tissue.
The general concept is to cause controlled microtrauma to the tissue, which will give rise to a regenerative response consisting of:
- Enhanced blood flow
- Stimulated cell metabolism
- Dissolution of calcified fibroblasts
- Stimulation of collagen synthesis
- Suppression of pain temporarily by nerve-ending overstimulation
Key Parameter #1: Why Pressure Matters in Shockwave Therapy
Pressure is the driving component that imparts energy into the body. Under shockwave treatment, it defines the maximum pressure each wave obtains. Pressure ordinarily lies between 10 to 100 megapascals (MPa), depending on application and device.
Effects of Different Pressure Levels
The pressure level determines the response of the tissues:
- Low pressure: appropriate for superficial tissue or sensitive tissues like tendons around joints.
- Moderate to high pressure: required for deeper tissue, e.g., hip flexors or chronic calcific tendinitis.
- High pressure releases substance: This aids in modulating pain and enhancing comfort.
- Stimulates VEGF release: stimulates new blood vessel creation for tissue repair.
- Increased circulation with deeper pressure: improves delivery of oxygen and nutrient exchange.
- May stimulate mechanoreceptors: Facilitates neuromuscular relaxation and pain control.
- Intensity should be adjusted: Depending on tissue depth, patient sensitivity, and therapeutic objectives.
Tailoring Pressure to the Condition
Physiotherapists adjust pressure levels depending on factors such as:
- Location and depth of the injury
- Chronicity of the condition
- Tissue sensitivity
- Patient comfort and tolerance
Key Parameter #2: The Role of Pulses in Therapeutic Outcomes
The frequency of the pulse, expressed in Hertz (Hz), governs the number of shockwaves administered per second. Typical frequencies are between 1 and 20 Hz, and the frequency selection influences how the treatment will be perceived and how the energy is distributed.
- Lower frequency (1–5 Hz): Facilitates deeper tissue penetration. The more leisurely rhythm allows tissues to absorb more energy per pulse.
- Higher frequency (10–20 Hz): More appropriate for large, superficial areas or when time is of the essence.
Energy Flux Density (EFD)
A key here is Energy Flux Density (EFD), a combination of pressure and frequency to indicate the proper therapeutic dose. It’s expressed in MJ/mm² and assists clinicians in measuring how much energy is being delivered to the tissues.
- Low EFD is used for acute injuries, sensitive tissues, or early-stage conditions, where excessive energy might cause discomfort or aggravation.
- High EFD is more suitable for chronic injuries, scar tissue breakdown, or when stimulation of tissue regeneration is desired.
EFD helps clinicians fine-tune treatment intensity to avoid under- or over-treating the target area, which is vital for safety and effectiveness.
Clinical Considerations
Optimal results are achieved by balancing frequency and EFD:
- Chronic injuries, like tendon issues or scar tissue, typically require lower pulse frequencies and higher EFD to penetrate deeper tissues and stimulate biological repair, including collagen synthesis, angiogenesis, and cell regeneration.
- Acute or tender tissues are improved with more pulse frequency and lower EFD, producing a less intense, more superficial action that will decrease pain, relax muscles, and increase circulation without stressing the tissues too much.
Key Parameter #3: Getting to the Root of the Problem
Penetration depth is an important consideration when employing shockwave therapy, particularly in the case of injuries deep within the body. Gluteal tendinopathy, hamstring injury, and thickened plantar fascia are some of these conditions that need enough energy to penetrate the tissues for effective therapeutic outcomes.
Depth varies with:
- Type of shockwave (focused waves penetrate deeper)
- Size and shape of the applicator
- Angle and pressure of application
Balancing Depth with Safety
Successful penetration should eschew hypersensitivity of essential structures like blood vessels and nerves. That’s why clinical accuracy is paramount, shallow waves don’t traverse to the harmed tissue, to deep, undue discomfort or irritation is a hazard. Achieving the right depth makes the shockwaves trigger biological reactions in just the right location. Such reactions are:
- Increased blood flow to the area
- Rapid tissue regeneration
- Calcific deposit or fibrotic tissue breakdown
- Modulation of pain through nerve desensitization
Matching Depth to Assessment
Various kinds of injuries necessitate particular depths of targeting
- Superficial: Patellar tendinopathy, tennis elbow
- Mid-depth: Achilles tendinopathy, medial epicondylitis
- Deep: Piriformis syndrome, high hamstring tendinopathy
Conditions That May Benefit from Shockwave Therapy
Shockwave therapy may be suggested if standard physiotherapy and rest have not settled chronic pain or inflammation. Typical conditions treated frequently include:
- Plantar fasciitis
- Achilles tendinopathy
- Rotator cuff injuries
- Tennis elbow
- Patellar tendinopathy
- Calcific shoulder tendinitis
- Myofascial trigger points
- Hip bursitis
