Table 1 Summary of Included Studies

From: Brief pain re-assessment provided more accurate prognosis than baseline information for low-back or shoulder pain

Reference Setting and study design Sample Follow-up Outcome measures Absolute scores (mean (SD)) on disability outcome N(%) of participants meeting 30% improvement cut-off at long-term follow-up
Dunn & Croft 2006 [22] Primary care; Prospective cohort 430 patients with LBP (mean age 44.7 years; 47% male) Four weeks and 12 months Disability (RMDQ) – score of between 0–24 with a higher score indicating higher disability Baseline: 9.02 (6.63)
4 weeks: 7.48 (6.48)
12 months: 6.61 (6.74)
228 (24) at 12 months
Kuijpers et al. 2006 [20] Primary care; prospective cohort 512 patients with a new episode of shoulder pain (mean age 51.49 years; 49.7% male) Six weeks and six months Recovery: Two categories (1: 0 = Not recovered and 1 = Recovered; 2: Global perceived recovery based on a 7-point Likert scale (6 = very much improved to 0 = very much deteriorated))
Disability (SDQ – score of between 0–100 – higher score indicating higher disability)
Baseline: 59.89 (24.21)
6 weeks: 40.32 (30.28)
6 months: 27.30 (31.26)
354 (60) at six months
Swinkels-Meewisse et al. 2006 [23] Primary care; Prospective inception cohort 300 patients with acute LBP (less than four weeks duration) (mean age 43.01 years; 58.2% male) Six weeks and six months Disability (RMDQ, see Dunn) Baseline: 13.15 (5.02)
6 weeks: 6.15 (5.45)
6 months: 4.42 (5.17)
303 (55) at six months
van der Windt et al. 1996 [19] Primary care; Prospective cohort 300 patients with a new episode of shoulder pain (mean age 49.52 years; 44.4% male) Four weeks and 12 months Recovery: Two categories (1: 0 = Persisting symptoms and 1 = Full recovery/much improved; 2: Global perceived recovery based on a 5-point Likert scale (5 = Much improved to 0 = Much deteriorated))
Disability (SDQ, see Kuijpers)
Baseline: 66.6 (23.4)
4 weeks: 47.1 (31.3)
12 months: 29.0 (30.3)
214 (64) at 12 months
