Physiotherapy alongside biologic therapy in inflammatory arthritis — timing and approach

The expansion of biologic and targeted therapies has transformed outcomes in inflammatory arthritis. A question that comes up regularly in co-management is how physiotherapy fits alongside these treatments — and the short answer is: it integrates well, and the two are genuinely complementary.

The complementary relationship

Biologic therapy targets the underlying inflammatory process; physiotherapy addresses the functional consequences — strength, mobility, conditioning, and quality of life. Neither replaces the other. In practice, better inflammatory control often enables more effective physiotherapy, because patients can engage with and progress through exercise that active disease would have limited.

Timing considerations

Coordinating the timing of physiotherapy with disease state improves results:

• During good control — the window to progress strength and conditioning more assertively
• During flares — shift to modified, gentler activity rather than ceasing entirely
• Around medication changes — awareness of disease-activity shifts helps calibrate exercise load

Communication between disciplines

Co-management works best with light-touch but real communication. Brief updates around flares, medication changes, or significant functional change help align approaches. The patient benefits from a coordinated message rather than conflicting advice from different providers.

Infection-risk awareness

Medication management for patients on biologics — including any health considerations associated with these therapies — sits with the treating medical team, not the physiotherapist. The physiotherapist's role is to stay coordinated with that team, communicate openly, and be responsive to any general signs that a patient is unwell, referring back rather than working in isolation.

What to communicate to patients

1. Exercise is part of treatment, not separate from it — and it works alongside their medication.
2. Continue all prescribed medical treatment — physiotherapy is additive.
3. Activity adjusts with disease state — they'll learn to modulate, not stop, during flares.
4. Long-term engagement delivers the functional and quality-of-life benefits.

Summary

Physiotherapy and biologic therapy are allies in inflammatory arthritis management. Coordinated timing, clear inter-disciplinary communication, and a consistent message to the patient maximise the combined benefit. Any specific clinical considerations around a patient's biologic therapy should be directed to and confirmed with the treating rheumatologist.
