What Is Tennis Elbow?

Tennis elbow — clinically known as lateral epicondylalgia — is pain and tenderness on the outer bony prominence of the elbow (lateral epicondyle). Despite its sporting name, 95% of people who develop tennis elbow have never played tennis. It affects 1–3% of the general population and is particularly common in people aged 35–55 who perform repetitive wrist and forearm movements.

In Faridabad, we commonly see tennis elbow in office workers (mouse and keyboard use), factory workers (repetitive gripping), tradespeople (screwdrivers, hammers), and recreational sports players (badminton, cricket).

Cause and Pathology

Tennis elbow is a tendinopathy — a degenerative condition of the common extensor tendon (primarily the ECRB: extensor carpi radialis brevis). The tendon undergoes a failed healing response, developing disorganised collagen fibres and increased vascularity (neovascularisation) rather than normal fibrous tissue. This is why rest alone does not resolve the condition — the tendon needs progressive loading to remodel.

Symptoms

Pain and tenderness on the outer elbow, specifically at the lateral epicondyle
Pain with gripping activities: shaking hands, turning a door handle, lifting a kettle
Weakness in the forearm and grip
Morning stiffness that improves with movement
Pain radiating down the forearm

Evidence-Based Physiotherapy Treatment

Progressive Tendon Loading (Gold Standard)

The most effective treatment for tennis elbow is progressive loading of the extensor tendon. We prescribe a systematic programme:

Week 1–2: Isometric wrist extension (pain-free, 3 sets × 45 seconds)
Week 3–4: Isotonic exercises with light resistance band (slow eccentric phase)
Week 5–8: Heavy slow resistance training (3 sets × 8–12 reps, progressive load)
Week 8+: Functional and sport-specific loading

Manual Therapy

Lateral elbow mobilisation with movement (Mulligan technique) provides immediate pain reduction during gripping. Soft tissue techniques for the forearm extensors. Cervical and thoracic spine assessment — referred pain from C6 mimics tennis elbow.

Electrotherapy

Ultrasound therapy promotes tendon healing. LASER therapy shows good evidence for reducing pain in lateral epicondylalgia.

Equipment Modification

For tennis players: grip size assessment, string tension review, technique analysis. For office workers: ergonomic mouse and keyboard setup. A forearm strap (counter-force brace) reduces load on the common extensor origin during activity.

How Long Does Recovery Take?

Tennis elbow is a tendinopathy and heals slowly. Most patients see significant improvement in 6–8 weeks with a proper loading programme. Full recovery typically takes 3–6 months. Patience and consistency with the loading programme are the key determinants of success.
