Pain/side-flexion group:
Group 1 (low-pain-good-motion): Back+leg pain ≤32 & side-flexion ≥13.5 cm
Group 2 (intermediate group): Back+leg pain ≤32 & side-flexion <13.5 cm
or back+leg pain >32 & side-flexion ≥13.5 cm
Group 3 (high-pain-restricted-motion): Back+leg pain >32 & side-flexion <13.5 cm
Number of risk factors (0-4):
‘Not convinced about return to work within 6 months’, ‘blaming the work for pain’, ‘drinking alcohol less than once/month’, ‘no home owner ship’.
Number of bodily distress symptoms the last 4 weeks (0-11).
‘Headaches?’, ‘Dizziness or faintness?’, ‘Pains in heart or chest?’, ‘Nausea or upset stomach?’, ‘Soreness of your muscles?’, ‘Trouble getting your breath?’, ‘Hot or cold spells?’, ‘Numbness or tingling in parts of your body?’, ‘A lump in your throat?’, ‘Feeling weak in
