Abstract

OBJECTIVES: Fibromyalgia (FM) is a chronic condition characterized by widespread musculoskeletal pain, fatigue, depression, and hypocortisolism. To date, published studies have not investigated the effects of yoga on cortisol in FM. This pilot study used a time series design to evaluate pain, psychological variables, mindfulness, and cortisol in women with FM before and after a yoga intervention. METHODS: Participants (n = 22) were recruited from the community to participate in a 75 minute yoga class twice weekly for 8 weeks. Questionnaires concerning pain (intensity, unpleasantness, quality, sum of local areas of pain, catastrophizing, acceptance, disability), anxiety, depression, and mindfulness were administered pre-, mid- and post-intervention. Salivary cortisol samples were collected three times a day for each of two days, pre- and post-intervention. RESULTS: Repeated measures analysis of variance (ANOVA) revealed that mean ± standard deviation (SD) scores improved significantly (p < 0.05) from pre- to post-intervention for continuous pain (pre: 5.18 ± 1.72; post: 4.44 ± 2.03), pain catastrophizing (pre: 25.33 ± 14.77; post: 20.40 ± 17.01), pain acceptance (pre: 60.47 ± 23.43; post: 65.50 ± 22.93), and mindfulness (pre: 120.21 ± 21.80; post: 130.63 ± 20.82). Intention-to-treat analysis showed that median AUC for post-intervention cortisol (263.69) was significantly higher (p < 0.05) than median AUC for pre-intervention levels (189.46). Mediation analysis revealed that mid-intervention mindfulness scores significantly (p < 0.05) mediated the relationship between pre- and post-intervention pain catastrophizing scores. DISCUSSION: The results suggest that a yoga intervention may reduce pain and catastrophizing, increase acceptance and mindfulness, and alter total cortisol levels in women with FM. The changes in mindfulness and cortisol levels may provide preliminary evidence for mechanisms of a yoga program for women with FM. Future studies should use an RCT design with a larger sample size.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The Describing, Acting-with-awareness, and Non-judging facets tend to show similar positive associations with psychological health.

    “The Describing, Acting-with-awareness, and Non-judging facets are often similarly associated with better psychological health.”

    From Mindfulness is associated with psychological health and moderates the impact of fibromyalgia (2019) · cites this paper as [13]

    The Five Facet Mindfulness Questionnaire section names all three facets and says that its subscales correlate with aspects of psychological functioning. It gives a positive association for Describing, but does not establish positive associations for Acting with awareness and Non-judging or show that the three are similarly associated with psychological health. The Results section reports improvement in Describing, not a comparison of those associations. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • The five facets of mindfulness have different relationships with health outcomes.

    “These facets of mindfulness differ in their associations with health outcomes.4–10,13–17”
  • The study sample had higher average total FFMQ scores than other community and clinical samples.

    “Our sample had higher average total Five Facet Mindfulness Questionnaire (FFMQ) scores than other community and clinical samples in studies that measured FFMQ5,7,10,13,15,17”
  • Yoga has been shown to reduce pain in other pain-centric conditions, such as fibromyalgia, rheumatic diseases, and multiple sclerosis.

    “In particular, yoga, which may partially exert its salubrious effects through enhanced interoceptive awareness [10], has been shown to reduce pain in other pain-centric conditions, such as fibromyalgia [11], rheumatic diseases [12], and multiple sclerosis [13].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
