Manipulation + mobilization versus placebo

Acute/subacute nonspecificPain intensity (NRS 0–10)Low
Design: RCT
ROB: Medium
Consistency: NA (one trial)
Directness: yes
In one trial [153] there were nonsignificant differences in pain intensity. Immediate posttreatment: −2.0 (95% CI: −0.7, 0.3) versus −0.1 (95% CI: −0.6, 0.4); short-term posttreatment: −0.2 (95% CI: −0.7, 0.3) versus 0.0 (95% CI: −0.5, 0.4).
Roland-Morris Disability scoreLow
Design: RCT
ROB: Medium
Consistency: NA (one trial)
Directness: yes
In one trial [153] there were nonsignificant differences in disability. Immediate posttreatment: −1.0 (95% CI: −2.0, 0.1) versus −0.7 (95%CI: −1.8, 0.4); short-term: −0.5 (95% CI: −1.7, 0.7) versus −0.1 (95% CI: −1.3, 1.1).

Design: RCT
ROB: Medium
Consistency: NA (one trial)
Directness: yes
In one trial [154] the combination of manipulation and mobilization was associated with significantly greater improvements in intermediate- and long-term posttreatment pain intensity (numerical data not provided).

Mixed nonspecificPain intensity (VAS score)Low
Design: RCT
ROB: Medium
Consistency: NA (one trial)
Directness: yes
In one trial [156], the combination of manipulation and mobilization (with or without physical modalities) was not significantly different from medical care alone or medical care combined with physical modalities immediately posttreatment or in the long-term posttreatment measures of pain.

Design: RCT
ROB: Medium
Consistency: NA (one trial)
Directness: yes
In one trial [156], the combination of manipulation and mobilization (with or without physical modalities) was not significantly different from medical care alone or medical care combined with physical modalities immediately posttreatment and in the long-term posttreatment measures of disability.

Design: RCT
ROB: Medium
Consistency: NA (one trial)
Directness: yes
In one trial [212] subjects receiving manipulation plus mobilization had significantly improved long-term disability. The mean change was 1.03 in the manipulation group versus 0.67 in the hospital outpatient treatment group at short-term posttreatment followup, and 0.94 versus 0.73 at intermediate-term posttreatment followup, respectively.

Design: RCT
ROB: Medium
Consistency: NA (one trial)
Directness: yes
In one trial [158] the manual therapy group showed significantly greater improvements than the exercise therapy group on pain intensity. The immediate posttreatment means (SD) in the manual therapy and exercise group were: 22 (18.56) and 37 (25.12), respectively.
The corresponding means (SD) at short-term posttreatment followup were 22 (19.88) versus 39 (22.53).
The corresponding means (SD) at intermediate-term posttreatment followup were 21 (14.58) versus 35 (35.89).

Directness: yes
In one trial [158] the manual therapy group showed significantly greater improvements than the exercise therapy group on disability. The posttreatment mean (SD) in the manual therapy versus exercise group were:
(a) immediate followup: 18 (13.26) versus 30 (10.77)
(b) short-term followup: 18 (11.93) versus 30 (14.36)
(c) intermediate-term followup: 17 (13.25) versus 26 (14.36).
