Tennis Elbow: Causes, Symptoms and How Physiotherapy Can Help

Despite its name, tennis elbow has little to do with tennis for most people who suffer from it. Officially known as lateral epicondylitis, this painful condition of the outer elbow affects office workers, factory employees, hawker stall operators, and home cooks across Malaysia far more often than it affects racquet sport players. If gripping a coffee mug, turning a doorknob, or shaking hands has become painful, tennis elbow may be the culprit.

What Exactly Is Tennis Elbow?

Tennis elbow involves degeneration and micro-tearing of the tendons that attach to the lateral epicondyle – the bony bump on the outside of your elbow. The primary tendon affected is the extensor carpi radialis brevis (ECRB), which helps stabilise the wrist when the elbow is straight. Rather than acute inflammation, research now shows that tennis elbow is predominantly a degenerative tendon condition (tendinopathy) involving failed healing of repetitive micro-damage.

The condition typically affects people between 30 and 50 years of age and occurs equally in men and women. It is estimated that 1-3% of the population is affected at any given time.

Root Causes and Risk Factors

Understanding what triggers tennis elbow helps guide effective treatment:

• Repetitive wrist extension and gripping – Using a mouse and keyboard for hours daily is the leading cause among Malaysian office workers in KL and Selangor
• Forceful gripping activities – Cooking with a wok, using hand tools, wringing clothes, and carrying heavy bags place significant load on the forearm extensors
• Racquet sports with poor technique – A late backhand, incorrect grip size, or excessive string tension can overload the lateral elbow
• Sudden increase in activity – Starting a new hobby, DIY renovation project, or exercise routine without gradual progression
• Neck and shoulder dysfunction – Research increasingly shows that cervical spine problems and poor shoulder blade control can contribute to lateral elbow pain

How to Identify Tennis Elbow

Tennis elbow symptoms usually develop gradually over weeks rather than appearing suddenly:

• Pain on the outer elbow that may radiate down the forearm toward the wrist
• Weakness in grip strength – difficulty holding objects, opening jars, or lifting with the palm facing down
• Pain when shaking hands, turning door handles, or pouring from a kettle
• Tenderness directly over the lateral epicondyle when pressed
• Pain that worsens with wrist extension against resistance
• Morning stiffness in the elbow that eases with gentle movement

If you recognise these symptoms, it is important to seek professional assessment rather than trying to self-diagnose. Many conditions share similar symptoms, and an accurate diagnosis is crucial for effective treatment.

Physiotherapy Treatment Approaches

Physiotherapy is the gold standard treatment for tennis elbow, with research strongly supporting its effectiveness over corticosteroid injections for long-term outcomes.

Tendon Loading Programme

The most critical component of treatment is a progressive tendon loading programme. This follows the principle that tendons need controlled stress to heal and remodel:

• Isometric exercises – Holding a contraction without movement to reduce pain and begin the loading process
• Eccentric exercises – Slowly lowering a weight with the wrist, which stimulates tendon healing and remodelling
• Heavy slow resistance training – Progressively heavier exercises through full range of motion to build tendon capacity
• Wrist and forearm strengthening – Thorough strengthening of all forearm muscles to distribute load more evenly

Manual Therapy and Adjunct Treatments

Hands-on techniques complement the exercise programme:

• Mobilisation with movement – The Mulligan technique applies a lateral glide to the elbow during gripping, often providing immediate pain relief
• Dry needling – Targeting trigger points in the forearm extensors and related muscles to reduce pain and improve muscle function
• Shockwave therapy – Effective for chronic cases that have not responded to exercise alone, stimulating a healing response in the degenerated tendon
• Cervical and thoracic spine assessment – Addressing any neck or upper back dysfunction that may be contributing to the elbow pain

Recovery Expectations

Tennis elbow typically resolves within 6-12 months with appropriate physiotherapy. Most patients experience significant improvement within 6-8 weeks of starting a structured loading programme.

However, patience is essential – tendons heal slowly and rushing the process leads to setbacks. Your physiotherapist will guide you through each phase and adjust the programme based on your response.

Workplace Modifications for Malaysian Office Workers

For the many Malaysians whose tennis elbow stems from desk work, ergonomic changes are essential:

• Use an ergonomic mouse and consider alternating hands or using a vertical mouse
• Position your keyboard so your wrists remain neutral rather than extended
• Take micro-breaks every 30 minutes to stretch your forearms
• Use a forearm brace (counterforce strap) during aggravating activities to redistribute forces away from the damaged tendon
• Adjust your desk height so your elbows rest at approximately 90 degrees

Get Expert Help for Your Elbow Pain

Tennis elbow is a frustrating condition, but it responds well to expert physiotherapy. Do not rely on rest alone – without progressive loading, the tendon does not develop the capacity to handle your daily demands.
