SHOCKIS / CLINICAL APPLICATION
Tennis Elbow
Lateral epicondylitis — commonly known as tennis elbow — is characterized by chronic degeneration at the origin of the extensor carpi radialis brevis muscle at the lateral epicondyle of the humerus.
Disease Overview
Lateral epicondylitis — commonly known as tennis elbow — is characterized by chronic degeneration at the origin of the extensor carpi radialis brevis muscle at the lateral epicondyle of the humerus. It is usually caused by injury or overuse. This condition is frequently associated with repetitive gripping, wrist extension, and occupational or athletic loads involving the forearm extensor muscles.
Typical Symptoms and Associated Factors
Symptoms include pain, weakness, and stiffness on the lateral side of the elbow. Associated factors encompass repetitive manual tasks, weakness in the shoulder and wrist muscles, as well as training or occupational loads that exceed the adaptive capacity of the tendon.

Professional Evaluation
The diagnosis is based on a comprehensive clinical history, physical examination, and exclusion of alternative causes such as radial nerve entrapment or elbow osteoarthritis.

Conservative Management
Conservative treatments include rest, ice application, analgesic medications, non-steroidal anti-inflammatory drugs, orthoses, physical therapy, and eccentric training/stretching. Glucocorticoid injection is a separate intervention that may be considered for specific patients, with individualized assessment of potential benefits and risks. Treatment selection should be tailored to the individual clinical situation.

ESWT: Potential Mechanisms and Limitations of Evidence
Extracorporeal Shock Wave Therapy (ESWT) is a non-invasive treatment that uses a device to deliver acoustic shock waves through the skin to the affected area. The exact mechanisms by which this therapy may exert effects on tendinopathy have not been fully elucidated. The evidence base for ESWT in lateral epicondylitis is inconsistent.

Contact with SHOCKIS
Clinicians and procurement professionals evaluating shock wave therapy systems for lateral epicondylar tendinopathy should consider device-specific characteristics and the applicable regulatory status in their respective regions. The evidence summarized above reflects the broader ESWT literature and does not constitute validation of any specific SHOCKIS product for any particular indication. If you wish to discuss how SHOCKIS can support your clinical or procurement needs, our team is welcome to hear from you.
Clinical Workflow Checklist
- 01CLINICAL ASSESSMENT
Review patient history, symptoms, and contraindications.
- 02TARGET AREA IDENTIFICATION
Identify the treatment area through clinical examination and appropriate imaging when needed.
- 03TREATMENT SETUP
Select treatment parameters according to clinical assessment, device instructions, and patient tolerance.
- 04SHOCKWAVE APPLICATION
Apply coupling gel and deliver treatment while monitoring patient response.
- 05POST-TREATMENT CARE
Clean the treatment area and applicator, and provide appropriate aftercare guidance.
Safety Information
The information below describes conditions and reactions generally associated with extracorporeal shock wave therapy. It does not replace the instructions for use of the specific SHOCKIS device. Clinicians must verify applicability against the current device labeling and their own clinical judgment.
Contraindications & Precautions
Shock wave therapy should not be applied, or should be applied only with particular caution, in the following situations:
- Known hemorrhagic disorders or coagulation dysfunction
- Thrombosis in or adjacent to the intended treatment area
- Severe cognitive impairment or psychiatric illness
- Implanted pacemakers or other active electronic implants
- Tumors located in the treatment area
- Pregnancy, particularly the lower abdominal region
- Ruptured or severely injured tendons and fasciae, as well as regions containing the brain, spinal cord, large blood vessels, or major nerve trunks
- Regions containing abdominal organs, especially lung tissue
- Bone defects exceeding 2 cm
- Joint fluid leakage
- Growing pains in pediatric patients
Any other condition deemed unsuitable by the treating physician.
Potential Adverse Reactions
The following reactions may occur at or near the treatment site:
- Local hematoma, ecchymosis, or petechiae
- Temporary intensification of pain shortly after treatment
- Local numbness, needle-like sensation, or hypoesthesia
- High-energy extracorporeal shock wave therapy may cause local nerve or vascular injury
These reactions are generally transient and typically resolve within approximately one week without special treatment.
