How Long Does Physiotherapy Actually Take to Work?
Realistic timelines for common injuries, what determines the pace, and the three things that make recovery take twice as long as it should.
Nobody books physiotherapy hoping to be there for three months. The honest answer is that it depends on the tissue involved, how long the problem has been going on, and what you do between appointments — but that is not much use as a plan, so here are the actual numbers.
Typical timelines
These are the ranges we quote at assessment, assuming you do the home programme:
- Acute muscle strain or ligament sprain — 4 to 6 weeks, around 6 sessions
- Uncomplicated low back pain — 4 to 8 weeks, 6 to 8 sessions
- Tendinopathy (Achilles, patellar, elbow) — 10 to 14 weeks, because tendons remodel slowly
- Frozen shoulder — 3 to 9 months, largely dictated by which phase you present in
- Post-operative joint replacement — 12 to 16 weeks to functional discharge
- ACL reconstruction — 9 to 12 months to return to pivoting sport
What sets the pace
Biology you cannot rush
Muscle heals faster than tendon; tendon faster than bone in some respects; cartilage barely at all. No treatment shortcuts collagen remodelling. What good rehabilitation does is make sure the tissue heals under the right amount of load, so it ends up strong rather than merely healed.
How long it has been there
A problem you have had for three weeks generally resolves faster than the same problem at three years. Long-standing pain brings deconditioning and a more sensitised nervous system, both of which take time to reverse.
What you do between sessions
This is the biggest variable and the one you control. Two sessions a week is roughly 90 minutes of clinic time; there are another 10,000 minutes in that week. The home programme is not homework we set to look thorough — it is the treatment.
Three things that double the timeline
- 1 Boom and bust. A good day, too much activity, three bad days. Repeated weekly, this keeps a problem alive for months. Pacing is unglamorous and it works.
- 2 Stopping when the pain stops. Pain settles at roughly the halfway point of tissue capacity. Stopping there is the single most common reason people are back six months later.
- 3 Passive treatment only. Heat, ultrasound and massage feel good and relieve symptoms. None of them make tissue stronger. If your treatment plan has no loading in it, ask why.
How to tell it is working
Progress in rehabilitation is rarely a straight line, which is why we measure rather than rely on how a session felt. Range of motion, strength and function get re-tested every fourth session and charted. If those numbers are not moving by session four to six, the plan changes or we refer you on.
