Spinal manipulation vs. other treatments (sham SMT, analgesics, exercises, physical therapy, etc.) analgesics, exercises, physical therapy, etc.)
Meta-Analyses Association With Pain
Short-term pain: Mean effect of -9.95mm ( 95% CI, -15.6 to -4.3; I2= 67%) on a 0-100mm scale in favour of SMT in comparison with other treatments Immediate-term pain: Mean effect of -9.76mm (95% CI, -17.0 to -2.5) on a 0-100mm scale in favour of SMT in comparison to comparison to other treatments
Association With Function
Short-term function: Effect size of -0.39 (95%CI, -0.71 to -0.07; I2= 72%) in favour of SMT in comparison with other treatments Immediate-term function: No statistically significant effect on function (effect size -0.24mm; 95% CI, -0.55 to 0.08)
Studies Considered Separately
4 RCTs excluded from pooled analysis due to common characteristics
◦ 2 low quality RCTs reported benefits in favour of SMT ◦ 1 high quality RCT stratified patients according to a clinical prediction rule identifying patients most likely to benefit from SMT; those identified as more likely to benefit from SMT, showed benefit in function at 1 week ◦ 1 high quality RCT used the same clinical predication rule. SMT group had statistically significant benefits in pain and function, but the magnitude of benefits was smaller in comparison to the other 3 studies.
Adverse Events
8 RCTs prospectively investigated harms in patients receiving SMT using a questionnaire 50% to 67% of patients reported mild, transient harms Local discomfort or increased pain were most frequently reported
| The quality of evidence was judged as moderate that treatment with SMT was associated with improved pain and function in patients with acute low back pain” (p1457)20
“The quality of evidence was judged as high that SMT is commonly associated with transient minor musculoskeletal harms, although they may be equally common following non-SMT manual therapy.”(p1457)20
“The principal conclusion of this review was that SMT treatments for acute low back pain were associated with statistically benefit in pain and function at up to 6 weeks, that was, on average clinically modest.”(p1457)20 |

Spinal Manipulation
RCT of 240 patients
◦ Randomized into 4 groups: diclofenac 50mg, b.i.d. + sham therapy, placebo + SMT, diclofenac + SMT, and placebo + sham therapy. ◦ All patients received advice from their GP and were prescribed acetaminophen 1g q.i.d. ◦ Groups did not differ in number of days to sustained pain freedom, level of pain measured via VAS, functional impairment on ODI or patient perceptions
RCT of 104 patients
◦ Received standard care (acetaminophen, diclofenac, and dihydrocodeine) with or without spinal manipulation ◦ No statistically significant differences reported between groups for pain measured via VAS or analgesic use
Massage
| “for patients with acute or subacute, nonradicular LBP, available evidence does not support the use of spinal manipulation or exercise therapy in addition to standard medical therapy. There is insufficient evidence to determine if yoga or massage is beneficial.”(p61)11 |

Chiropractic vs. physical therapy modalities
Meta-analysis pooled patients (n= 204) from 3 RCTs on spinal manipulation, manual therapy and massage therapy demonstrated no statistically significant effects on pain, function or range of motion
◦ Pain : SMD 0.13 (95% CI, -0.72 to 0.99; I2 = 87.4%) at 2 weeks; SMD 0.02 (95% CI, -0.67 to 0.70; I2 = 80.5%) at 6 weeks ◦ Disability: SMD -0.02 (95% CI, -0.76 to 0.72; I2 83.3%) at 2 weeks ◦ Flexion range of motion : SMD 0.50 (95% CI, -0.02 to 1.02; I2 = 66.6%) at 2 weeks
| Authors report “chiropractic may have a favourable effect on self-reported pain and functional limitations on NSCLBP.”(p11)3 despite no statistically significant differences in pain, function or range of motion.
“the results should be interpreted in the context of the limitations identified, particularly in relation to the heterogeneity in the study characteristics and the low methodological quality in many of the included studies.”(p11)3 |

Manual therapy vs. usual care or standard prenatal care
Statistically significant effect of manual therapy on
◦ Pain intensity (SMD -0.70; 95% CI, -1.10 to -0.30) ◦ Pain disability (SMD-0.62; 95% CI, -0.93 to -0.31)
Manual therapy vs. relaxation
Manual therapy vs. sham
No statistically significant effect demonstrated on
◦ Pain intensity (SMD 0.05; 95%CI, -0.15 to 0.26) ◦ Pain disability (SMD -0.08; 95% CI, -0.40 to 0.25)
| “the results indicated a moderate treatment effect of manual therapies for decreasing pain intensity compared to usual care and relaxation, and a moderate effect on pain disability compared to usual care.” (p7)13
“ no positive effect on manual therapies were found for either pain intensity or pain disability when compared to sham interventions”(p7)13
“This review also found positive effects for pain disability for craniosacral technique and osteopathy compared to usual care”(p7)13
“These findings are consistent with a recent Cochrane review suggesting moderate-quality evidence from individual studies that indicate osteopathic manipulative therapy significantly reduced LBP and disability” (p7)13
“There is currently limited evidence to support the use of manual therapies including massage and osteopathic manipulative treatment as an option for managing LBP and PGP during pregnancy. Current research is associated with risk of
publication and methodological biases, and lack of robust control comparisons.”(p8)13 |

Spinal manipulation vs. sham manipulation Results from SR:
Pain: SMT group reported lower levels of pain posttreatment and at follow-up in 5 of the 6 included RCTs Function: SMT group reported improved OLBPDQ scores in 2 of the 4 included RCTs Adverse Events: 3 RCTs reported adverse events, transient local discomfort and tiredness was reported in 1 RCT and 2 reported no adverse events occurred
Results from MA:
| “results of the meta-analysis suggest a greater reduction in pain scores among participants receiving SM in comparison to those receiving an effective sham placebo. This finding remained consistent when looking at pain recorded at immediately posttreatment and follow-up”(p173)22
“In terms of clinical relevance, this is only a small to moderate effect,[53,54] and the CIs are wide. Caution is needed before drawing conclusions because most studies had some degree of RoB”(p173)22
“given the small number of studies included in this analysis, we should be cautious of making strong inferences based on these results.” (p165)22 |

Low back pain: Manual therapy + usual prenatal care vs.
1 RCT found added benefit from adding OMT to usual care on pain ( effect size -7.11; 95% CI, -10.30 to - 3.93) and functional disability ( effect size -2.25; 95% CI, -3.18 to -1.32) in comparison to usual care alone 1 RCT found no statistically significant difference in pain ( effect size 0.14; 95% CI, -0.26 to 0.53) or functional disability (effect size 0.35; 95% CI, -0.06 to 0.76) in OMT + usual care group in comparison to prenatal care + placebo ultrasound 1 RCT found OMT + usual care more effective in pain reduction in comparison to usual prenatal care ( between-group mean difference 3.5; 95% CI, 2.4 to 4.6) 1 RCT found no statistically significant difference in pain or functional disability between exercise, NET and SMT groups
