The Integrative Migraine Pain Alleviation through Chiropractic Therapy (IMPACT) trial: Study rationale, design and intervention validation.

INTRODUCTION: Approximately 15% of the US population experiences migraine, with women afflicted three times as often as men. While medications are often used as first-line treatments, up to 50% of people with migraine pursue complementary and integrative medicine. One promising non-pharmacological approach for migraine is chiropractic care, due to the co-occurrence of migraine disease and musculoskeletal tension and pain. To date, no large-scale trials have evaluated the impact of a comprehensive model of chiropractic care on migraine. METHODS: The Integrative Migraine Pain Alleviation through Chiropractic Therapy (IMPACT) study is a two-arm pilot pragmatic randomized clinical trial evaluating a multimodal chiropractic care intervention plus enhanced usual care (UC) vs. enhanced UC alone for adult women with episodic migraine. A total of 60 women aged 20-55 who meet criteria for episodic migraine will be randomly assigned to an evidence-informed, musculoskeletal focused multimodal chiropractic care (10 sessions over 14 weeks) plus enhanced UC vs. enhanced UC alone. Enhanced UC includes conventional care, migraine education materials, and biweekly check-in phone calls. Study specific aims include: 1) Determine safety and feasibility of the study design; 2) Provide preliminary data on the effectiveness of chiropractic care on migraine frequency, severity, duration and medication use; and 3) Provide preliminary estimates of the effects of chiropractic care on disability, health-related quality of life, and psychosocial well-being. DISCUSSION: Findings will be used to inform the design of a full-scale trial evaluating chiropractic care for women with episodic migraines.

Tai Chi and Qigong for cancer-related symptoms and quality of life: a systematic review and meta-analysis.

PURPOSE: This study aims to summarize and critically evaluate the effects of Tai Chi and Qigong (TCQ) mind-body exercises on symptoms and quality of life (QOL) in cancer survivors. METHODS: A systematic search in four electronic databases targeted randomized and non-randomized clinical studies evaluating TCQ for fatigue, sleep difficulty, depression, pain, and QOL in cancer patients, published through August 2016. Meta-analysis was used to estimate effect sizes (ES, Hedges' g) and publication bias for randomized controlled trials (RCTs). Methodological bias in RCTs was assessed. RESULTS: Our search identified 22 studies, including 15 RCTs that evaluated 1283 participants in total, 75% women. RCTs evaluated breast (n = 7), prostate (n = 2), lymphoma (n = 1), lung (n = 1), or combined (n = 4) cancers. RCT comparison groups included active intervention (n = 7), usual care (n = 5), or both (n = 3). Duration of TCQ training ranged from 3 to 12 weeks. Methodological bias was low in 12 studies and high in 3 studies. TCQ was associated with significant improvement in fatigue (ES = - 0.53, p < 0.001), sleep difficulty (ES = - 0.49, p = 0.018), depression (ES = - 0.27, p = 0.001), and overall QOL (ES = 0.33, p = 0.004); a statistically non-significant trend was observed for pain (ES = - 0.38, p = 0.136). Random effects models were used for meta-analysis based on Q test and I 2 criteria. Funnel plots suggest some degree of publication bias. Findings in non-randomized studies largely paralleled meta-analysis results. CONCLUSIONS: Larger and methodologically sound trials with longer follow-up periods and appropriate comparison groups are needed before definitive conclusions can be drawn, and cancer- and symptom-specific recommendations can be made. IMPLICATIONS FOR CANCER SURVIVORS: TCQ shows promise in addressing cancer-related symptoms and QOL in cancer survivors.

The impact of Tai Chi and Qigong mind-body exercises on motor and non-motor function and quality of life in Parkinson's disease: A systematic review and meta-analysis.

PURPOSE: To systematically evaluate and quantify the effects of Tai Chi/Qigong (TCQ) on motor (UPDRS III, balance, falls, Timed-Up-and-Go, and 6-Minute Walk) and non-motor (depression and cognition) function, and quality of life (QOL) in patients with Parkinson's disease (PD). METHODS: A systematic search in 7 electronic databases targeted clinical studies evaluating TCQ for individuals with PD published through August 2016. Meta-analysis was used to estimate effect sizes (Hedges's g) and publication bias for randomized controlled trials (RCTs). Methodological bias in RCTs was assessed by two raters. RESULTS: Our search identified 21 studies, 15 of which were RCTs with a total of 735 subjects. For RCTs, comparison groups included no treatment (n = 7, 47%) and active interventions (n = 8, 53%). Duration of TCQ ranged from 2 to 6 months. Methodological bias was low in 6 studies, moderate in 7, and high in 2. Fixed-effect models showed that TCQ was associated with significant improvement on most motor outcomes (UPDRS III [ES = -0.444, p < 0.001], balance [ES = 0.544, p < 0.001], Timed-Up-and-Go [ES = -0.341, p = 0.005], 6 MW [ES = -0.293, p = 0.06], falls [ES = -0.403, p = 0.004], as well as depression [ES = -0.457, p = 0.008] and QOL [ES = -0.393, p < 0.001], but not cognition [ES = -0.225, p = 0.477]). I2 indicated limited heterogeneity. Funnel plots suggested some degree of publication bias. CONCLUSION: Evidence to date supports a potential benefit of TCQ for improving motor function, depression and QOL for individuals with PD, and validates the need for additional large-scale trials.
