Physiotherapy for low back pain starts with a structured clinical assessment to understand symptoms and likely contributors, identify situations requiring medical referral, and create an individualized plan. Treatment may include graded therapeutic exercise, education, selected adjunctive techniques and regular progress review.
First, understand the pain and the problem
Low back pain is a symptom, not a single diagnosis. It may involve nerve irritation, muscular or joint-related factors, or be non-specific without one clearly identifiable anatomical source. Assessment explores onset, location, duration, aggravating and easing factors, and whether pain travels into the leg or is associated with numbness or weakness.
A relevant clinical examination may assess spinal movement, strength, motor control, functional capacity and neurological findings where indicated. The goal is to develop a reasoned clinical assessment rather than assume that every episode is caused by a disc.
Not every case can be attributed to one precise pain-generating structure, and imaging findings alone do not necessarily explain symptoms.
When is further medical assessment needed?
A central part of physiotherapy assessment is recognising who is suitable for rehabilitation and who needs further medical care. Significant trauma, fever with unusual back pain or progressive neurological symptoms may change the clinical pathway.
New bladder or bowel dysfunction, numbness in the saddle area, or severe/progressive weakness in the legs require urgent medical assessment.
Physiotherapy: from clinical assessment to a treatment plan
Once assessed, we set meaningful goals: reducing pain, improving movement, tolerating sitting or walking, returning to work and rebuilding confidence with activity.
Individual care may include progressive therapeutic exercise for mobility, strength and capacity; education and self-management; and gradual adjustment of activity loads. Manual therapy may be considered as an adjunct to a programme that includes exercise, not as a stand-alone replacement for active rehabilitation.
The type, dose and progression of exercises follow the assessment, the person’s abilities and response—not a fixed routine for everyone.
Two examples: same complaint, different pathways
Someone with discomfort after prolonged sitting and no clear neurological signs might benefit from gradual movement, activity pacing and progressive strengthening.
Someone else with back pain radiating into the leg and numbness needs closer neurological and movement assessment to decide whether conservative care is appropriate or medical referral is needed. Both report low back pain, but the clinical pathways differ.
How do we measure progress?
Progress is evaluated using symptoms and meaningful activities, such as walking, sitting, sleeping and working. At follow-up, the plan is adjusted based on response, functional gains and any new findings.
Prolonged complete rest is generally not helpful; many people benefit from staying appropriately active while rehabilitation is progressed. Unexpected progression or new symptoms call for reassessment and, when indicated, referral.
Key takeaway
Good physiotherapy is a process of clinical assessment, individual planning, graded treatment, follow-up and measured outcomes—not simply distributing exercise lists. It also means recognising when medical assessment beyond rehabilitation is needed.
