Tennis Elbow: Why It Happens, Why It Hurts, and How We Fix It (Properly)

Tennis elbow (lateral elbow tendinopathy) is one of the most common upper-limb injuries I treat as a sports physiotherapist in London. And despite its name, the condition affects far more than just tennis players — I see it regularly in boxers, recreational athletes, weightlifters, desk-based workers, and anyone experiencing a sudden or sustained overload to the elbow and forearm.

This week alone, I’ve had two new tennis elbow patients, and both developed symptoms after boxing. It’s a perfect example of how this condition is not simply an elbow problem, but often a whole-upper-limb load management problem.

Understanding why the tendon becomes irritated is the first step toward effective, long-term recovery.

Why Tennis Elbow Develops (The Load–Capacity Explanation)

1: Sudden or rapid increase in load

High-quality research on tendon pathology — particularly the Tendon Continuum Model by Cook & Purdam (2009) — shows that tendinopathy often develops when load exceeds tissue capacity.
This can occur when someone:

  • Starts boxing or hitting the bag more frequently

  • Returns to gym training after time off

  • Performs repetitive gripping or lifting tasks

  • Increases training intensity too quickly

When the forearm extensors are exposed to a spike in demand, the tendon becomes reactive and symptomatic.

2: Gradual overload without adequate recovery

Some people develop tennis elbow gradually.
Micro-loading accumulates over time, and because recovery doesn’t match training stress, the tendon slowly becomes overloaded.

This explains why some patients say:

“It just crept up on me — I can’t think of a single moment where it started.”

When Tennis Elbow Isn’t Just a Tendon Problem: The Neural Component

Several studies, including a systematic review by Clewley et al. (2014), highlight that neural sensitivity — particularly involving the radial nerve — can contribute to lateral elbow pain.

This is why SOME patients experience:

  • Sharp, shooting discomfort

  • Pain radiating down the forearm

  • Tightness that doesn’t respond to stretching alone

Ignoring the neural component can delay recovery. Addressing it accelerates progress. Having an assessment by a professional who is capable to identify if you have any neural component of your injury will be crucial to help manage the condition effectively.


Why the Elbow Takes the Hit: Poor Load Transfer in the Upper Limb

A common question patients ask is:

“Why is it my elbow that hurts, not my wrist or shoulder?”

The answer lies in biomechanics and load transfer.

If the shoulder lacks stability, or the rotator cuff and scapula aren’t controlling movement well, the elbow becomes the compensator.


Similarly, poor wrist stability during gripping or punching increases strain on the common extensor tendon.


Research by Lucado et al. (2019) supports this, showing that proximal (shoulder and scapular) strengthening plays a significant role in reducing elbow overload.

This is especially relevant in sports like boxing, where force transmission through the upper limb must be highly coordinated.


Evidence-Based Treatment Approach for Tennis Elbow

As a sports physiotherapist, my treatment framework combines hands-on therapy with targeted loading, neural intervention when required, and structured strengthening that addresses both local symptoms and global biomechanics.

1. Mobilisations With Movement (MWM)

A common treatment technique used widely by Australian and New Zealand Physiotherapists, Mobilisations with Movement (MWM) techniques aim to work immediately, and is a form of ‘Active therapy’.

I really like using MWM’s as the client feels like they’re part of the recovery, not just coming in to get a massage and needles poking into their arm.

Vicenzino et al. (2001) demonstrated that MWM techniques can:

  • Reduce pain immediately

  • Improve pain-free grip strength

  • Enhance function

In clinic, a lateral glide applied while the patient performs the painful movement often reduces symptoms by 30% or more — a reliable indicator that the technique is effective.

2. Taping to Reinforce the Lateral Glide

I often apply specific taping that mimics the MWM glide.


This supports the joint, reduces strain on the tendon, and provides short-term relief during daily activities or sport.


When applied properly, the tape usually allows our clients to continue using their arm with significantly less pain, which ends up ‘tricking’ the brain to think that it’s not painful to do the previously painful thing (eg carrying your bag, opening a bottle, lifting weights etc).


It allows your muscles to function, allowing you to take active steps toward your own recovery.

3. Dry Needling for Pain Modulation

Dry needling can effectively reduce muscular tone, decrease pain sensitivity, and improve movement tolerance — making it a helpful adjunct before beginning heavier exercise loading.

4. A Structured, Progressive Rehabilitation Plan (The Foundation of Recovery)

Research consistently shows that progressive tendon loading is the most effective long-term treatment for lateral elbow tendinopathy.

Landmark Study:

Stasinopoulos & Stasinopoulos (2006) demonstrated that isometric, eccentric, and eccentric–concentric exercises all significantly improve pain and function.

This is why exercise rehabilitation is the backbone of my approach.

Direct Tendon-Targeted Exercises

Isometric Wrist Extensions

Isometrics reduce pain and restore muscle activation.
The analgesic effect is well supported by Rio et al. (2015).

Heavy Grip Holds (e.g., kettlebell carries)

These load the entire extensor mechanism and help rebuild strength for functional gripping tasks.

Isotonic Strengthening Progressions

Including:

  • Wrist extension

  • Supination

  • Pronation

These gradually increase tendon capacity and resilience.

Wrist extension isotonic exercise for tennis elbow.

Indirect Exercises: Fixing the Root Cause

To prevent recurrence, rehab must address the proximal factors that overloaded the elbow in the first place.

My go-to exercises include:

  • Dumbbell external rotations (rotator cuff)

  • Powell raises (scapular stability)

These exercises improve shoulder mechanics, enhance force transfer, and reduce stress on the elbow — supported by Lucado et al., 2019.

The Key Principle: Treat the Upper Limb as a Biomechanical System

Long-term success comes from addressing:

  • The tendon

  • The neural component

  • The shoulder and scapular stability

  • The movement patterns that caused overload

  • The sport-specific demands (e.g., boxing, tennis, weight training)

When these components are integrated, people don’t just get pain-free — they return to sport stronger than before.
