Tennis Elbow (Lateral Epicondylitis)
Outer elbow pain with gripping, typing, and lifting, not just from tennis.
What it is
Tendinopathy of the common extensor tendon at the outer elbow, driven by chronic overload of grip and wrist extensors.
Common symptoms
- Outer elbow pain with gripping
- Pain lifting a coffee cup or shaking hands
- Tender at the lateral epicondyle
Why it happens: root cause
Forearm tendon capacity vs. repetitive grip load. When load on a tissue chronically exceeds its capacity, pain shows up. My job is to close that gap, by lowering load, raising capacity, or both, so the tissue stops being overwhelmed.
A closer look
Lateral epicondylitis, tendinopathy of the common extensor tendon at the outer elbow, driven by chronic overload of grip and wrist-extensor demand. Not just from tennis: gripping, typing, lifting, and manual work are the usual culprits.
What causes it (LOAD > CAPACITY = PAIN)
- Forearm extensor tendon capacity vs repetitive grip load
- Sudden increases in gripping or manual tasks
- Poor wrist/forearm strength
- Sometimes a shoulder/scapular contribution
Why it keeps coming back
- Grip and forearm capacity not rebuilt
- Returning to heavy gripping too soon
- Ergonomic triggers unaddressed
Why rest, stretching, and passive care aren't enough
Braces and rest reduce symptoms but don't build tendon capacity, and progressive loading is the driver, and shockwave and laser both have meta-analytic support for this tendon.
Conditions that can mimic this
- Radial tunnel syndrome (nerve)
- Cervical referral
- Posterolateral elbow instability
- Referred shoulder issues
Clarius MSK ultrasound can confirm the extensor tendon and help rule other causes in or out.
How I treat it
How the ADAPT Method treats your Tennis Elbow (Lateral Epicondylitis)
- A
Assess
Confirm lateral epicondyle tendinopathy by exam (grip tests, resisted wrist extension) and screen the neck, shoulder, and grip habits feeding it. Clarius MSK ultrasound is used when it sharpens the diagnosis.
- D
Decrease Pain
Modify grip-heavy tasks short-term, then layer Focused Shockwave (ESWT), Radial Pressure Wave (EPAT), and EMTT on the lateral epicondyle and forearm extensors to calm the tendon, and laser therapy (photobiomodulation) can be added for reactive flares.
- A
Activate
Restore wrist, forearm, and shoulder mobility, and screen the cervical spine if it's contributing.
- P
Progress
Heavy-slow grip and wrist extension loading, the proven driver of tendon adaptation here.
- T
Transfer
Return-to-activity plan (sport, racquet, work tasks) with a 5-minute daily grip routine you actually keep doing.
ADAPT closes the gap between LOAD and CAPACITY, lowering what's stressing the tissue while building what the tissue can handle.
FAQ
What causes tennis elbow if I don't play tennis?+
Most cases come from grip-heavy work, typing, lifting toddlers, tools, mousing, climbing. The tendon couldn't keep up with chronic grip load.
Should I wear an elbow strap?+
It can take the edge off short-term but doesn't rebuild capacity. Useful scaffolding while I load the tendon, not a fix.
Does shockwave actually work?+
Yes. Focused Shockwave for tennis elbow is one of the better-supported uses in the literature, especially combined with progressive loading.
What about cortisone?+
Cortisone in the lateral epicondyle gives short-term relief but worse long-term outcomes than load-based care. I avoid it as a first-line.
Do I need an MRI?+
Usually no, at least not first. Most musculoskeletal issues are diagnosed by history and exam. I use Clarius MSK diagnostic ultrasound in-office when it actually changes the plan: confirming a tendon issue, ruling between two diagnoses, or guiding treatment. I refer for MRI when red flags or surgical questions warrant it.
Should I stop training?+
Modify, not stop. Pull-ups, deadlifts, and racquet sport often get dosed down for a stretch while loading rehabs the tendon.
How long does it take to recover?+
6–12 weeks of disciplined loading typically produces real change; remodeling continues for months.
Will it come back?+
Only if grip strength fades. A short maintenance set keeps it gone.
Do you take insurance?+
Form & Function is a cash-based (self-pay) practice; I don't bill insurance directly. That lets me spend more time with you and build your plan around what you actually need, not what an insurer will approve. Fees are discussed up front. On request I can provide a detailed receipt (superbill) you may submit to your insurance for possible out-of-network reimbursement, though reimbursement isn't guaranteed.
What happens at the first visit?+
I sit down and talk through your history, training, and what you've already tried. Then I go through a hands-on movement and strength assessment, look at the painful area (and the joints above and below), and use Clarius MSK ultrasound in-office when it sharpens the diagnosis. You leave with a working diagnosis and a written plan, not a vague 'come back next week.'
