Abstract

Objective: To examine the daily life patterns of both pain and fatigue symptoms and objective physical activity (using ambulatory monitoring) in women with symptomatic lower extremity osteoarthritis (OA), and to evaluate how momentary symptoms impact physical activity levels. Methods: Sixty women age ≥55 years (40 with knee or hip OA and 20 matched controls) participated in an observational study involving 2 laboratory visits and a 5‐day home data collection period. During the home period physical activity levels were assessed continuously, and symptoms were inputted 6 times a day into an enhanced accelerometer at prespecified time points. Results: In the OA group as compared with the control group over the 5‐day period, average physical activity was significantly lower (P = 0.02) and peak physical activity tended to be lower (P = 0.06). Although pain and fatigue overall were of moderate severity in this cohort, fatigue escalated throughout each day. In a hierarchical linear model, fatigue was most strongly associated with physical activity (β = −30.1, P < 0.0001). Pain was more weakly associated with physical activity and in the direction opposite to what was hypothesized (β = 16.9, P = 0.04). Conclusion: Momentary reports of fatigue negatively predicted physical activity levels and were much more strongly related to physical activity than momentary pain. In order to help women with knee or hip OA manage symptoms and become more physically active, it may be important to emphasize fatigue management.

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

  • The single-item measures used to assess momentary symptoms have not been validated.

    “Use of single item measures that have not been validated to assess momentary symptoms is a limitation of this study.”

    From Ecological momentary assessment of pain, fatigue, depressive, and cognitive symptoms reveals significant daily variability in multiple sclerosis (2017) · cites this paper as [81]

    The ‘Subjective measures collected by the Actiwatch-S’ section describes momentary pain and fatigue ratings, supporting the use of single-item symptom measures. The Discussion identifies the 0–4 scale’s limited comparability with other studies, but does not say the symptom measures were unvalidated; it discusses Actiwatch-S validity separately. No page numbers were available in our copy. (LLM, conf=0.78)

    Experimental — accuracy not yet measured

  • There are no standard, validated ecological momentary assessment measures of the symptoms examined in this study.

    “to our knowledge there are no standard, validated EMA measures of the symptoms examined in this study.”

    From Ecological momentary assessment of pain, fatigue, depressive, and cognitive symptoms reveals significant daily variability in multiple sclerosis (2017) · cites this paper as [81]

    The Subjective measures section describes the study’s 0–4 momentary pain and fatigue ratings, and the Discussion says this scale was chosen to reduce respondent burden rather than using the more common 0–10 scale. Neither passage says that standard, validated EMA measures of these symptoms do not exist; searches for validated EMA measures and symptom-scale validity found no such statement in our copy. Page numbers were not available. (LLM, conf=0.72)

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.
