Shockwave Therapy for Tennis Elbow in Cape Town

The moment people usually notice it is not at the gym or on a court. It is picking up a full kettle, and having to put it down again. Or lifting a laptop bag off the passenger seat and feeling a sharp catch on the outside of the elbow. Or shaking someone's hand and wincing.

Tennis elbow is a badly named condition that affects a lot of people who have never held a racquet. It is stubborn, it is frustrating, and it responds poorly to the two things most people try first, which are rest and a brace. Understanding why explains what actually works.

Why do most people with tennis elbow never play tennis?

Because the condition is about gripping and loading the wrist, not about a particular sport. The name comes from where it was first described, not from where most cases come from.

The tissue involved is the common extensor origin on the outside of the elbow, where the muscles that straighten your wrist and fingers attach to the bone. One of those muscles in particular, the extensor carpi radialis brevis, takes the brunt of it. Any activity that repeatedly loads those tendons at their attachment can produce the problem.

In the practice the groups we see most are office workers who spend long hours on a mouse and keyboard, tradespeople using hand tools, gym goers doing a lot of rowing, deadlifting, pull ups and kettlebell work, gardeners and people midway through a home renovation, new parents lifting a car seat several times a day, and yes, racquet sport players, though these days padel appears at least as often as tennis.

The other thing worth knowing is that despite the name ending in itis in older textbooks, this is not primarily an inflammatory condition. When the tissue has been examined in longer standing cases, what shows up is degeneration and failed healing rather than active inflammation. That is why lateral epicondylalgia, or lateral elbow tendinopathy, is the more accurate label, and it is also why anti inflammatory approaches so often disappoint.

What actually triggers it in everyday life?

Almost always a change rather than the activity itself. The elbow was coping with your normal week, and then something increased.

A new job with more screen time. A weekend of painting or tiling. A gym programme with more pulling volume. A different mouse or desk height. Taking up padel and playing three times a week within a month of starting. A baby who has grown heavier. It is rarely one dramatic event and almost always an accumulation that outpaced what the tendon could adapt to.

Once it has started, the aggravating list is remarkably consistent. Lifting a kettle or a mug, carrying a laptop bag or shopping in one hand, turning a key or a door handle, opening a jar, using a screwdriver, and gripping the steering wheel on a longer drive.

Why is it so painful to grip things?

This is the part that confuses people. The painful tendons belong to muscles that extend the wrist, so why does closing your hand hurt?

Because to grip firmly, your wrist has to be held stable and slightly extended. The wrist extensors contract hard to provide that stability every time you squeeze. They are working just as much during a grip as during a deliberate wrist movement, which is why a strong handshake or a full kettle finds the sore spot immediately.

A measurable drop in grip strength is common with this condition, and it is one of the more useful things to track. It gives us an objective marker that often improves before the pain fully settles, which is reassuring at the point in rehabilitation where progress feels slow.

Why does a brace help without fixing the problem?

A counterforce strap worn just below the elbow works by changing where load is transmitted, taking some of the pull off the attachment itself. For many people it takes the edge off immediately, which is genuinely useful.

What it does not do is change the tendon. Wearing a strap reduces the load reaching the irritated tissue, so symptoms improve while it is on and return when it comes off, because the tendon's capacity has not moved. Braces are a helpful tool during the period when you are loading the tendon back up. Used as the whole plan, they tend to keep people comfortable enough to avoid dealing with the underlying problem for months.

The same logic applies to rest. Stopping everything that hurts lowers the pain because it lowers the demand, and the tendon quietly detrains at the same time. Then normal life resumes and you are back where you started, sometimes worse. This is one of the reasons lateral elbow pain has a reputation for lasting a year or more. It is often a year of resting, bracing and flaring rather than a year of treatment.

How does shockwave restart the healing response in a stalled tendon?

In a tendon that has been sore for months, the repair process has effectively stopped. The tissue shows disorganised collagen, changes in the matrix, and small new blood vessels and nerve endings growing into the area, which contributes to the pain.

Shockwave therapy delivers rapid acoustic pressure waves into the tendon through a handpiece pressed against the outside of the elbow. That controlled mechanical stimulus appears to restart the repair response in tissue that has gone quiet, increase local blood flow, and change how the tendon signals pain.

Sessions take around five minutes over a fairly small area, feel like firm rapid tapping, and are distinctly tender over the sore point. Intensity is built up to what you can tolerate. Most courses run to between three and six sessions about a week apart, with no injection and no downtime. Some tenderness for a day or two afterwards is normal.

Shockwave is not a standalone treatment for tennis elbow and should not be sold as one. Its value is that it lowers the tendon's irritability enough for the loading programme to be progressed properly, instead of being wound back every time the elbow flares. The treatment and the loading plan are one plan, delivered together by the physiotherapy and biokinetics teams.

What does grip and wrist extensor loading look like?

It builds in stages, and it is deliberately unexciting.

Isometrics usually come first. Holding the wrist in extension against a fixed resistance for a sustained period loads the tendon without the movement that irritates it, and for many people it reduces pain for a while afterwards, which makes it useful before a working day.

The main phase is slow, heavy wrist extensor work. Controlled wrist extension with a weight or a resistance bar, performed with a slow lowering phase, a few times a week, gradually increasing the load. Grip strengthening runs alongside it, because grip is both the thing that hurts and the function you need back. Forearm rotation work is often added, since turning a screwdriver or a door handle loads the tendon differently again.

We also look further up the arm. Weak shoulder and shoulder blade control means the forearm works harder to do the same task, so shoulder strengthening is frequently part of an elbow programme even though it seems unrelated. Alongside that we go through the practical side: mouse and desk setup, how you carry bags, grip size on tools or a racquet, and how to spread the heavy tasks through a week rather than stacking them into a Saturday.

The biokinetics team at Peak Movement builds and progresses this programme while the physiotherapist runs the shockwave course and manages your symptoms week to week. Expect this to take a few months rather than a few weeks, and expect the strength work to continue past the point where the elbow feels fine, because that is what keeps it from coming back.

What does this look like at Peak Movement?

Peak Movement is on Strand Street in the Cape Town City Centre, with physiotherapy and biokinetics in the same practice, so the treatment and the loading programme run as one coordinated plan.

Your first appointment is an assessment. We confirm the common extensor origin is the source rather than the elbow joint, a nerve irritation in the forearm, or referred pain from the neck, which is a genuine possibility with lateral elbow pain. We test your grip, look at how your wrist, elbow and shoulder are loading, and go through what changed at work or in training before this started. If shockwave suits your presentation we explain why and what a course involves.

Payment is settled at the time of your session. You receive a full invoice including ICD-10 codes, which you then submit to your medical aid yourself.

Frequently asked questions

Can I still use my arm with tennis elbow?

Yes, and you should. Complete rest tends to leave the tendon weaker rather than better. We usually modify rather than stop, reducing the heaviest gripping tasks, spreading them out through the week, and keeping loaded work going in a form the elbow tolerates. The guide is how the elbow feels the following morning rather than during a task.

Should I wear a tennis elbow brace?

A counterforce strap can be useful for symptom relief during the working day while you build strength, and many people find it takes the edge off immediately. Treat it as a tool rather than the treatment, because it changes where load is transmitted without changing the tendon's capacity. If the pain returns every time the strap comes off, the loading programme is the missing piece.

How long does tennis elbow take to get better?

Longer than most people expect. Cases picked up early can settle within a couple of months, while elbows that have been sore for six months or more often take three months or longer of consistent loading. Grip strength frequently improves before pain does, which is why we track both rather than judging progress on pain alone.

If the outside of your elbow has been sore for more than a few weeks, book an assessment with the physiotherapy and biokinetics team at Peak Movement on Strand Street.
