What the literature leaves open

  • The study identifies a need to assess the applicability of the 2016 revised ACR fibromyalgia diagnostic criteria in an Indian tertiary-care population. There is a lack of studies evaluating the 2016 revised ACR criteria in this population.

  • There is a lack of understanding of exercise dose as a dynamic construct that is shaped by symptom fluctuations, individual responses, and real-world adaptations. The authors highlight the need for improved reporting and monitoring of exercise dose to inform and improve clinical practice. There is a gap in the literature regarding the systematic monitoring of the executed exercise dose.

  • Longitudinal studies are needed to confirm the findings. Studies should investigate the relationship between kinesiophobia and work disability in other populations. Research should focus on developing interventions to reduce kinesiophobia and improve work disability outcomes. The role of pain catastrophizing in mediating the relationship between kinesiophobia and work disability should be further explored.
