Introduction[edit | edit source]
The first aim of the physiotherapy examination for a patient presenting with back pain is to classify the patient according to the diagnostic triage recommended in international back pain guidelines[1]. Serious (such as fracture, cancer, infection and ankylosing spondylitis) and specific causes of back pain with neurological deficits (such as radiculopathy, caudal equina syndrome)are rare[2] but it is important to screen for these conditions[1][3]. Serious conditions account for 1-2% of people presenting with low back pain and 5-10% present with specifics causes LBP with neurological deficits[4]. When serious and specific causes of low back pain have been ruled out individuals are said to have non-specific (or simple or mechanical) back pain.
Non-specific low back pain accounts for over 90% of patients presenting to primary care[5] and these are the majority of the individuals with low back pain that present to physiotherapy. Physiotherapy assessment aims to identify impairments that may have contributed to the onset of the pain, or increase the likelihood of developing persistent pain. These include biological factors (eg. weakness, stiffness), psychological factors (eg. depression, fear of movement and catastrophisation) and social factors (eg. work environment)[6]. The assessment does not focus on identifying anatomical structures (eg. the intervertebral disc) as the source of pain, as might be the case in peripheral joints such as the knee[6]. Previous research and international guidelines suggest it is not possible or necessary to identify the specific tissue source of pain for the effective management of mechanical back pain[1][3][7].
The subjective assessment (history taking) is by far the most important part of the assessment with the objective assessment (clinical testing) confirming or refuting hypothesis formed from the subjective.
Assessment of the lumbar spine should allow clinical reasoning to include appropriate data collection tests from those listed below.
Subjective
[edit | edit source]
The subjective examination is one of most powerful tools a clinician can utilize in the examination and treatment of patients with LBP. The questions utilized during this process can improve the clinician’s confidence in identification of sinister pathology warranting outside referral, screening for yellow flags which may interfere with PT interventions, and assist in matching PT interventions with a patient’s symptoms.
History not only is the record of past and present suffering but also constitutes the basis of future treatment, prevention and prognosis.

Patient Intake[edit | edit source]
- Self‐report (present complaint (PC), history of present compaint (HPC), past medical history (PMH), drug history (DH), social history (SH))
- Region‐specific questions
- What is the patient’s age?
- What is the patient’s occupation?
- What was the mechanism of injury?
- How long has the problem bothered the patient?
- Where are the sites and boundaries of pain?
- Is there any radiation of pain? Is the pain centralizing or peripheralizing
- Is the pain deep? Superficial? Shooting? Burning? Aching?
- Is the pain improving? Worsening? Staying the same?
- Is there any increase in pain with coughing? Sneezing? Deep breathing? Laughing?
- Are there any postures or actions that specifically increase or decrease the pain or cause difficulty?Is the pain worse in the morning or evening? Does the pain get better or worse as the day progresses? Does the pain wake you up at night?Which movements hurt? Which movements are stiff?
- Is paresthesia (a “pins and needles” feeling) or anesthesia present?
- Has the patient noticed any weakness or decrease in strength? Has the patient noticed that his/her legs have become weak while walking or climbing stairs?
- What is the patient’s usual activity or pastime? Before the injury, did the patient modify or perform any unusual repetitive or high-stress activity?
- Which activities aggravate the pain? Is there anything in the patient’s lifestyle that increases the pain?
- Which activities ease the pain?
- What is the patient’s sleeping position? Does the patient have any problems sleeping?
- Does the patient have any difficulty with micturition?
- Are there any red flags that the examiner should be aware of, such as a history of cancer, sudden weight loss for no apparent reason, immunosuppressive disorder, infection, fever, or bilateral leg weakness?
- Is the patient receiving any medication?
- Is the patient able to cope during daily activities?

tag; name cannot be a simple integer. Use a descriptive title.
- Cauda equina syndrome
- Cancer
- Ankylosing spondylitis
- Lumbar stenosis
- Lumbar disc herniations
- Vertebral fracture
- Spinal infection
- Abdominal aortic aneurysm
During the investigation you must pay attention to any ‘red flags’ that might be present indicating serious pathology. Koes et al (2006)[8] mentioned the following ‘red flags’:
- Onset age < 20 or > 55 years
- Non-mechanical pain (unrelated to time or activity)
- Thoracic pain
- Previous history of carcinoma, steroids, HIV
- Feeling unwell
- Weight loss
- Widespread neurological symptoms
- Structural spinal deformity

Other Flags[edit | edit source]
It is also important to screen for other (yellow, orange, blue and black) flags as these may interfere with physiotherpy interventions.

Outcome Measures[edit | edit source]
- Fear‐Avoidance Belief Questionnaire
- STarT Back Screening Tool
- Acute Low Back Pain Screening Questionnaire
- The Quebec Back Pain Disability Scale
- Oswestry Disability Index
- Hendler 10-Minute Screening Test for Chronic Back Pain Patients
- The Roland-Morris Disability Questionnaire
Investigations
[edit | edit source]
Has the patient had any other investigations such as radiology (Xray, MRI, CT, ultrasound) or blood tests?
Objective[edit | edit source]
The purpose of the objective examination (clinical testing) is to confirm or refute hypothesis formed from the subjective examination.
When assessing the lumbar spine, the examiner must remember that referral of symptoms or the presence of neurological symptoms often makes it necessary to “clear” or rule out lower limb pathology. Many of the symptoms that occur in the lower limb may originate in the lumbar spine. Unless there is a history of definitive trauma to a peripheral joint, a screening or scanning examination must accompany assessment of that joint to rule out problems within the lumbar spine referring symptoms to that joint.
Examination procedures should be performed from standing-sitting-lying and pain provocation movements saved until last.
Observation
[edit | edit source]
Movement Patterns
[edit | edit source]
- How does the patient enter the room?
- A posture deformity in flexion or a deformity with a lateral pelvic tilt, possibly a slight limp, may be seen.
- How does the patient sit down and how comfortably/ uncomfortably does he or she sit?
- How does the patient get up from the chair? A patient with low back pain may splint the spine in order to avoid painful movements.
Posture[edit | edit source]
Other observations[edit | edit source]
- body type
- attitude
- facial expression
- skin
- hair
- leg length discrepancy (functional, structural)
Functional Tests
[edit | edit source]
- Functional Demonstration of pain provoking movements
- Squat test - to highlight lower limb pathologies. Not be done with patients suspected of having arthritis or pathology in the lower limb joints, pregnant patients, or older patients who exhibit weakness and hypomobility. If this test is negative, there is no need to test the peripheral joints (peripheral joint scan) with the patient in the lying position[9].
Movement Testing[edit | edit source]
- AROM (flexion 40-60, extension 20-35, side flexion 15-20 - looking for willingness to move, quality of movement, where movement occurs, range, pain, painful arc, deviation)
- Overpressure (at the end of all AROM if they are pain free, normal end feel should be tissue stretch)
- Sustained positions (if indicated in subjective)
- Combined movements (if indicated in subjective)
- Repeated movements (if indicated in subjective)
- Muscle Strength (resisted isometrics in flex, ext, side flex, rotation; core stabilty, functional strength tests)

Circulatory Assessment[edit | edit source]
If indicated it may be necessary to perform a haemodynamic assessment.
Palpation[edit | edit source]
[11] |
It is crucial for a reliable diagnosis and intervention of treatment to adequately palpate the lumbar processi.
Within the scientific world there has been a debate about the palpation of the processi spinosi because scientists assumed that often different persons indicated the processi on a different place (Mckenzie et al)[12]. However, Snider et al (2011)[13] have shown that the indicated points of the different therapists lie that the distance between the indicated points of the different therapists is much smaller than it had always been claimed. Obviously there were differences because some therapists have more experience and others have more anatomical knowledge. Also the difference in personality between the therapists led to differences in locating the processi.
Furthermore, this investigation has proven that it is more useful to indicate different points instead of just 1 point. Also it has been proven that a manual examination to detect the lumbar segmental level is highly accurate when accompanied by a verbal subject response (Philips 1996).[14]
There are of course elements that hinder the palpation. For example, a BMI (body mass index) of 30kg/m2 considerably diminishes the accuracy (Ferre et al)[15]. Anatomical abnormalities might also cause problems. The abnormality of the 12th rib leads, for example, to a negative palpatory accuracy in the region L1-L4 for all therapists. [16]
- Passive Intervertebral Motion (PPIVMs, PAIVMs)
- Muscle Tone
Clear Adjacent Joints[edit | edit source]
[17] |
- Thoracic spine - seated rotation with combined movements and overpressure
- Sacroiliac joints - various tests have been described to clear the SIJ such as Gillet test, sacral clearing test, cluster tests
- Hips - PROM with overpressure
- Knees and ankles - should also be cleared for restrictions that may affect movement patterns
