Gutke A, Betten C, Degerskär K, Pousette S , Olsén MF. Treatments for pregnancy-related lumbopelvic pain: a systematic review of physiotherapy modalities. Acta Obstet Gynecol Scand. 2015;94(11):1156-67. [169565].

Objective	To explore the effect of physiotherapeutic interventions on pregnancy-related lumbopelvic pain.
Methods	Data sources: MEDLINE, Cochrane Central Register of Controlled Trials, PEDro, CINAHL, AMED, and SCOPUS databases were searched up to December 2014 for studies written in English, French, German or Scandinavian languages that evaluated physiotherapeutic modalities for preventing and treating pregnancy-related lumbopelvic pain.
Results	For lumbopelvic pain during pregnancy, the evidence was strong for positive effects of acupuncture and pelvic belts. The evidence was low for exercise in general and for specific stabilizing exercises. The evidence was very limited for efficacy of water gymnastics, progressive muscle relaxation, a specific pelvic tilt exercise, osteopathic manual therapy, craniosacral therapy, electrotherapy and yoga. For postpartum lumbopelvic pain, the evidence was very limited for clinic-based treatment concepts, including specific stabilizing exercises, and for self-management interventions for women with severe disabilities. No specific adverse events were reported for any intervention. No meta-analysis could be performed because of study heterogeneity.
Conclusions	The levels of evidence were strong for a positive effect of acupuncture and pelvic belts, but weak for an effect of specific exercises. Caution should prevail in choosing other interventions for pregnancy-related lumbopelvic pain.

1.2. Liddle 2015 ☆

Liddle SD, Pennick V. Interventions for preventing and treating low-back and pelvic pain during pregnancy.. Cochrane Database Syst Rev. 2015. [187873].

Background	More than two-thirds of pregnant women experience low-back pain and almost one-fifth experience pelvic pain. The two conditions may occur separately or together (low-back and pelvic pain) and typically increase with advancing pregnancy, interfering with work, daily activities and sleep.
Objectives	To update the evidence assessing the effects of any intervention used to prevent and treat low-back pain, pelvic pain or both during pregnancy.
Methods	Search methods: We searched the Cochrane Pregnancy and Childbirth (to 19 January 2015), and the Cochrane Back Review Groups' (to 19 January 2015) Trials Registers, identified relevant studies and reviews and checked their reference lists. Selection criteria: Randomised controlled trials (RCTs) of any treatment, or combination of treatments, to prevent or reduce the incidence or severity of low-back pain, pelvic pain or both, related functional disability, sick leave and adverse effects during pregnancy. Data collection and analysis: Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy.
Main results	We included 34 RCTs examining 5121 pregnant women, aged 16 to 45 years and, when reported, from 12 to 38 weeks' gestation. Fifteen RCTs examined women with low-back pain (participants = 1847); six examined pelvic pain (participants = 889); and 13 examined women with both low-back and pelvic pain (participants = 2385). Two studies also investigated low-back pain prevention and four, low-back and pelvic pain prevention. Diagnoses ranged from self-reported symptoms to clinicians' interpretation of specific tests. All interventions were added to usual prenatal care and, unless noted, were compared with usual prenatal care. The quality of the evidence ranged from moderate to low, raising concerns about the confidence we could put in the estimates of effect. For low-back painResults from meta-analyses provided low-quality evidence (study design limitations, inconsistency) that any land-based exercise significantly reduced pain (standardised mean difference (SMD) -0.64; 95% confidence interval (CI) -1.03 to -0.25; participants = 645; studies = seven) and functional disability (SMD -0.56; 95% CI -0.89 to -0.23; participants = 146; studies = two). Low-quality evidence (study design limitations, imprecision) also suggested no significant differences in the number of women reporting low-back pain between group exercise, added to information about managing pain, versus usual prenatal care (risk ratio (RR) 0.97; 95% CI 0.80 to 1.17; participants = 374; studies = two). For pelvic painResults from a meta-analysis provided low-quality evidence (study design limitations, imprecision) of no significant difference in the number of women reporting pelvic pain between group exercise, added to information about managing pain, and usual prenatal care (RR 0.97; 95% CI 0.77 to 1.23; participants = 374; studies = two). For low-back and pelvic painResults from meta-analyses provided moderate-quality evidence (study design limitations) that: an eight- to 12-week exercise program reduced the number of women who reported low-back and pelvic pain (RR 0.66; 95% CI 0.45 to 0.97; participants = 1176; studies = four); land-based exercise, in a variety of formats, significantly reduced low-back and pelvic pain-related sick leave (RR 0.76; 95% CI 0.62 to 0.94; participants = 1062; studies = two).The results from a number of individual studies, incorporating various other interventions, could not be pooled due to clinical heterogeneity. There was moderate-quality evidence (study design limitations or imprecision) from individual studies suggesting that osteomanipulative therapy significantly reduced low-back pain and functional disability, and acupuncture or craniosacral therapy improved pelvic pain more than usual prenatal care. Evidence from individual studies was largely of low quality (study design limitations, imprecision), and suggested that pain and functional disability, but not sick leave, were significantly reduced following a multi-modal intervention (manual therapy, exercise and education) for low-back and pelvic pain. When reported, adverse effects were minor and transient.
Authors' conclusions	There is low-quality evidence that exercise (any exercise on land or in water), may reduce pregnancy-related low-back pain and moderate- to low-quality evidence suggesting that any exercise improves functional disability and reduces sick leave more than usual prenatal care. Evidence from single studies suggests that acupuncture or craniosacral therapy improves pregnancy-related pelvic pain, and osteomanipulative therapy or a multi-modal intervention (manual therapy, exercise and education) may also be of benefit. Clinical heterogeneity precluded pooling of results in many cases. Statistical heterogeneity was substantial in all but three meta-analyses, which did not improve following sensitivity analyses. Publication bias and selective reporting cannot be ruled out. Further evidence is very likely to have an important impact on our confidence in the estimates of effect and change the estimates. Studies would benefit from the introduction of an agreed classification system that can be used to categorise women according to their presenting symptoms, so that treatment can be tailored accordingly.

1.3. Close 2014

Close C, Sinclair M, Liddle Sd, Madden E, Mccullough Je, Hughes C. A Systematic Review Investigating The Effectiveness of Complementary and Alternative Medicine (CAM) For The Management of Low Back And/Or Pelvic Pain (LBPP) In Pregnancy. J Adv Nurs. 2014;70(8):1702-16.[160458].

Objectifs	To evaluate and summarize the current evidence on the effectiveness of complementary and alternative medicine for the management of low back pain and/or pelvic pain in pregnancy. Background: International research demonstrates that 25-30% of women use complementary and alternative medicine to manage low back and pelvic pain in pregnancy without robust evidence demonstrating its effectiveness.
Méthodes	A systematic review of randomized controlled trials to determine the effectiveness of complementary and alternative medicine for low back and/or pelvic pain in pregnancy. Data sources: Cochrane library (1898-2013), PubMed (1996-2013), MEDLINE (1946-2013), AMED (1985-2013), Embase (1974-2013), Cinahl (1937-2013), Index to Thesis (1716-2013) and Ethos (1914-2013). Review Methods: Selected studies were written in English, randomized controlled trials, a group 1 or 2 therapy and reported pain reduction as an outcome measure. Study quality was reviewed using Risk of Bias and evidence strength the Cochrane Grading of Recommendations and Development Evaluation Tool.
Résultats	Eight studies were selected for full review. Two acupuncture studies with low risk of bias showed both clinically important changes and statistically significant results. There was evidence of effectiveness for osteopathy and chiropractic. However, osteopathy and chiropractic studies scored high for risk of bias. Strength of the evidence across studies was very low.
Conclusion	There is limited evidence supporting the use of general CAM for managing pregnancy-related low back and/or pelvic pain. However, the restricted availability of high-quality studies, combined with the very low evidence strength, makes it impossible to make evidence-based recommendations for practice.

1.4. Pennick 2013 ☆☆

Pennick V, Liddle SD. interventions for preventing and treating pelvic and back pain in pregnancy. cochrane database syst rev. 2013. CD001139. [160367].

Background	More than two-thirds of pregnant women experience low-back pain (LBP) and almost one-fifth experience pelvic pain. Pain increases with advancing pregnancy and interferes with work, daily activities and sleep.
Objectives	To assess the effects of interventions for preventing and treating pelvic and back pain in pregnancy.
Methods	Search methods: We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (18 July 2012), identified related studies and reviews from the Cochrane Back Review Group search strategy to July 2012, and checked reference lists from identified reviews and studies. Selection criteria: Randomised controlled trials (RCTs) of any treatment to prevent or reduce the incidence or severity of pelvic or back pain in pregnancy. Data collection and analysis: Two review authors independently assessed risk of bias and extracted data. Quality of the evidence for outcomes was assessed using the five criteria outlined by the GRADE Working Group.
Main results	We included 26 randomised trials examining 4093 pregnant women in this updated review. Eleven trials examined LBP (N = 1312), four examined pelvic pain (N = 661), and 11 trials examined lumbo-pelvic (LBP and pelvic) pain (N = 2120). Diagnoses ranged from self-reported symptoms to the results of specific tests. All interventions were added to usual prenatal care and unless noted, were compared to usual prenatal care. For LBP, there was low-quality evidence that in general, the addition of exercise significantly reduced pain (standardised mean difference (SMD) -0.80; 95% confidence interval (CI) -1.07 to -0.53; six RCTs, N = 543), and disability (SMD -0.56; 95% CI -0.89 to -0.23; two RCTs, N = 146); and water-based exercise significantly reduced LBP-related sick leave (risk ratio (RR) 0.40; 95% CI 0.17 to 0.92; one RCT, N = 241). Low-quality evidence from single trials suggested no significant difference in pain or function between two types of pelvic support belt, between osteopathic manipulation (OMT) and usual care or sham ultrasound (sham US). Very low-quality evidence suggested that a specially-designed pillow may relieve night pain better than a regular pillow. For pelvic pain, there was moderate-quality evidence that acupuncture significantly reduced evening pain better than exercise; both were better than usual care. Low-quality evidence from single trials suggested that adding a rigid belt to exercise improved average pain but not function; acupuncture was significantly better than sham acupuncture for improving evening pain and function, but not average pain; and evening pain relief was the same following either deep or superficial acupuncture. For lumbo-pelvic pain, there was moderate-quality evidence that an eight- to 20-week exercise program reduced the risk of women reporting lumbo-pelvic pain (RR 0.85; 95% CI 0.73 to 1.00; four RCTs, N = 1344); but a 16- to 20-week training program was no more successful than usual care at preventing pelvic pain (one RCT, N = 257). Low-quality evidence suggested that exercise significantly reduced lumbo-pelvic-related sick leave (RR 0.76; 95% CI 0.62 to 0.94, two RCTs, N = 1062), and improved function. Low-quality evidence from single trials suggested that OMT significantly reduced pain and improved function; either a multi-modal intervention that included manual therapy, exercise and education (MOM) or usual care significantly reduced disability, but only MOM improved pain and physical function; acupuncture improved pain and function more than usual care or physiotherapy; pain and function improved more when acupuncture was started at 26- rather than 20- weeks' gestation; and auricular (ear) acupuncture significantly improved these outcomes more than sham acupuncture. When reported, adverse events were minor and transient.
Authors' conclusions	Moderate-quality evidence suggested that acupuncture or exercise, tailored to the stage of pregnancy, significantly reduced evening pelvic pain or lumbo-pelvic pain more than usual care alone, acupuncture was significantly more effective than exercise for reducing evening pelvic pain, and a 16- to 20-week training program was no more successful than usual prenatal care at preventing pelvic or LBP. Low-quality evidence suggested that exercise significantly reduced pain and disability from LBP. There was low-quality evidence from single trials for other outcomes because of high risk of bias and sparse data; clinical heterogeneity precluded pooling. Publication bias and selective reporting cannot be ruled out. Physiotherapy, OMT, acupuncture, a multi-modal intervention, or the addition of a rigid pelvic belt to exercise seemed to relieve pelvic or back pain more than usual care alone. Acupuncture was more effective than physiotherapy at relieving evening lumbo-pelvic pain and disability and improving pain and function when it was started at 26- rather than 20-weeks' gestation, although the effects were small. There was no significant difference in LBP and function for different support belts, exercise, neuro emotional technique or spinal manipulation (SMT), or in evening pelvic pain between deep and superficial acupuncture. Very low-quality evidence suggested a specially-designed pillow may reduce night-time LBP. Further research is very likely to have an important impact on our confidence in the estimates of effect and is likely to change the estimates. Future research would benefit from the introduction of an agreed classification system that can be used to categorise women according to presenting symptoms.

1.5. Richards 2012

Richards E, Van Kessel G, Virgara R, Harris P. Does Antenatal Physical Therapy for Pregnant Women with Low Back Pain or Pelvic Pain Improve Functional Outcomes? A Systematic Review. Acta Obstet Gynecol Scand. 2012;91(9):1038-45. (eng). [166575]

Objectifs	A systematic review was undertaken to update the understanding of the available evidence for antenatal physical therapy interventions for low back or pelvic pain in pregnant women to improve functional outcomes when compared with other treatments or no treatment. Data Sources: Seven electronic databases were systematically searched and supplemented by hand searching through reference lists.
Méthodes	Two reviewers independently selected trials for inclusion and independently assessed the internal validity of the included trials using the Clinical Appraisal Skills Program tool.
Résultats	Four trials with 566 participants were identified that met the inclusion criteria. The validity of the trials was moderate. Exercise, pelvic support garments and acupuncture were found to improve functional outcomes in pregnant women with low back or pelvic pain. No meta-analysis was performed because of the heterogeneity of functional outcome measures.
Conclusion	While there is some evidence that physical therapy using exercise, acupuncture and pelvic supports may be useful, further research needs to consider other treatment modalities used by physical therapists and establish an appropriate, reliable and valid functional outcome measure to assess low back and pelvic pain in pregnancy.

Ee Cc et al. Acupuncture for pelvic and back pain in pregnancy: a systematic review. Am J Obstet Gyn. 2008;198-3:254-9. [148279].

Purpose	The objective of our study was to review the effectiveness of needle acupuncture in treating the common and disabling problem of pelvic and back pain in pregnancy.
Methods	We used a narrative synthesis due to significant clinical heterogeneity between trials. Few and minor adverse events were reported.
Results	Acupuncture, as an adjunct to standard treatment, was superior to standard treatment alone and physiotherapy in relieving mixed pelvic/back pain. Women with well-defined pelvic pain had greater relief of pain with a combination of acupuncture and standard treatment, compared to standard treatment al one or stabilizing exercises and standard treatment.
Conclusion	We conclude that limited evidence supports acupuncture use in treating pregnancy-related pelvic and back pain..

1.7. Pennick 2007 ☆

Pennick V, Young G. Interventions for preventing and treating pelvic and back pain in pregnancy. Cochrane Database Syst Rev. 2007. [145475].

Background	More than two-thirds of pregnant women experience back pain and almost one-fifth experience pelvic pain. The pain increases with advancing pregnancy and interferes with work, daily activities and sleep.
Objectives	To assess the effects of interventions for preventing and treating back and pelvic pain in pregnancy.
Methods	Search strategy: We searched the Cochrane Pregnancy and Childbirth Review Group's Trials Register (February 2006). Selection criteria : Randomised controlled trials of any treatment to prevent or reduce the incidence or severity of back or pelvic pain in pregnancy. Data collection and analysis: Two authors independently assessed trial quality and extracted data.
Main results	We found no studies dealing specifically with prevention of back or pelvic pain. We included eight studies (1305 participants) that examined the effects of adding various pregnancy-specific exercises, physiotherapy, acupuncture and pillows to usual prenatal care. For women with low-back pain, participating in strengthening exercises, sitting pelvic tilt exercises (standardised mean difference (SMD) -5.34; 95% confidence interval (CI) -6.40 to -4.27), and water gymnastics reduced pain intensity and back pain-related sick leave (relative risk (RR) 0.40; 95% CI 0.17 to 0.92) better than usual prenatal care alone. The specially-designed Ozzlo pillow was more effective than a regular one in relieving back pain (RR 1.84; 95% CI 1.32 to 2.55), but is no longer commercially available. Both acupuncture and stabilising exercises relieved pelvic pain more than usual prenatal care. Acupuncture gave more relief from evening pain than exercises. For women with both pelvic and back pain, in one study, acupuncture was more effective than physiotherapy in reducing the intensity of their pain; stretching exercises resulted in more total pain relief (60%) than usual care (11%); and 60% of those who received acupuncture reported less intense pain, compared to 14% of those receiving usual prenatal care. Women who received usual prenatal care reported more use of analgesics, physical modalities and sacroiliac belts.
Authors' conclusions	All but one study had moderate to high potential for bias, so results must be viewed cautiously. Adding pregnancy-specific exercises, physiotherapy or acupuncture to usual prenatal care appears to relieve back or pelvic pain more than usual prenatal care alone, although the effects are small. We do not know if they actually prevent pain from starting in the first place. Water gymnastics appear to help women stay at work. Acupuncture shows better results compared to physiotherapy.

1.8. Young 2001

Young G et al. Interventions for preventing and treating pelvic and back pain in pregnancy. Cochrane Library Oxford. 2001. [101018].

Background	More than a third of women experience back pain during pregnancy. The pain can interfere with work, daily activities and sleep.
Objectives	The objective of the review was to assess the effects of preventive interventions and treatments for pelvic and back pain in pregnancy.
Methods	Search strategy: We searched the Cochrane Pregnancy and Childbirth Group trials register (October 2001) and the Cochrane Controlled Trials Register (The Cochrane Library, Issue 3, 2001). Selection criteria: Randomised trials of any treatment to reduce the incidence or severity of pelvic/back pain in pregnancy, or to prevent pelvic/back pain arising in pregnancy. Data collection and analysis: Trial quality was assessed and data were extracted independently by two reviewers.
Main results	Three trials are included in this review involving 376 women. One randomized trial compared water gymnastics from 20 weeks with no treatment. The authors report less pain in the treatment group but the data are hard to interpret; there was a difference in rates of absence from work after 32 weeks of pregnancy (odds ratio 0.38, 95% confidence intervals 0.16-0.88). In another trial, acupuncture was rated as giving 'good' or 'excellent' help more frequently than physiotherapy (odds ratio 6.58, 95% confidence intervals 1.0-43.16) but this may reflect the benefit of individual compared with group therapy. One trial of 109 women compared the use of a special shaped pillow to fit under the woman's abdomen (Ozzlo pillow) with a standard pillow. Fewer women rated the Ozzlo pillow of 'little help' compared with the standard pillow (odds ratio 0.32, 95% confidence interval 0.18 to 0.58).
Reviewers' conclusions	Water gymnastics appear to reduce back pain in pregnancy. More women are able to continue at work. Specially shaped pillows help reduce back pain in late pregnancy and improve sleep. It is a pity that the Ozzlo pillow seems no longer to be available. Both physiotherapy and acupuncture may reduce back and pelvic pain. Individual acupuncture sessions were rated as more help than group physiotherapy sessions.
