What should improve — and what to watch

Recovery in tendinopathy is judged by trends, not by a single session. Three things matter more than pain at rest:

• Pain behaviour: how the tendon responds during and after load, and over the following 24 hours.
• Function and participation: the activities, sport or work the tendon needs to tolerate.
• Load capacity: how much the tendon can handle before it flares — this is the real target of rehabilitation.

Function and load capacity matter more than pain alone. A tendon can still be sensitive while genuinely getting stronger; conversely, pain easing without any gain in capacity is not yet a meaningful response.

A decision framework: continue, modify, reassess, refer or discharge

The principles below come from a proposed clinical decision framework. They are decision principles, not fixed rules — the right action depends on the tendon, the load demand, chronicity, irritability, adherence and the patient’s goals.

Clinical finding	Reasonable decision
Measurable functional / load-capacity improvement	Continue and progress the plan
Pain improves but function does not	Modify the plan (load, dosage, technique)
No change after an adequate, adherent trial	Reassess the diagnosis and the plan
Red flags or consistent worsening	Refer for medical assessment
Goals met or plateau after objective gains	Discharge to self-management

Common tendinopathies (brief examples)

• Achilles tendinopathy: pain and stiffness at the back of the heel or lower calf, typically worse with the first loads of the day and with running or jumping.
• Patellar tendinopathy (“jumper’s knee”): pain at the front of the knee just below the kneecap, provoked by jumping, landing and deceleration.
• Rotator cuff (shoulder) tendinopathy: pain with overhead and loaded shoulder movements.
• Lateral elbow tendinopathy (“tennis elbow”): pain over the outer elbow with gripping and wrist extension.

The underlying logic — judge response by load capacity and function, progress when it improves, modify or reassess when it does not — is shared across these tendons, even though the specific loading plan differs.

Frequently asked questions

How long before tendon rehabilitation works?

Tendons adapt slowly. Meaningful change usually takes weeks to months, not days — tendinopathy rehabilitation is a gradual, progressive process. If there is no change at all after an adequate, adherent trial, the plan or the diagnosis should be reassessed rather than simply continued or abandoned.

Is pain during loading bad?

Not necessarily. A tolerable level of pain during loading that settles back to baseline afterwards is often acceptable in tendinopathy rehabilitation. Sharp, escalating, or pain that keeps rising over the following day is a signal to reduce or modify the load. The acceptable level should be guided individually.

When should I see a doctor?

If there was a sudden “pop”, bruising or a sudden loss of strength (possible tendon rupture), or if there are systemic or atypical non-mechanical symptoms, seek medical assessment rather than continuing rehabilitation.
