Musculoskeletal pain refers to a number of conditions that affect the locomotor system of individuals, including bones, muscles, ligaments, tendons, and nerves. 1 There are more than 200 musculoskeletal conditions ranging from disorders such as neck or back pain to autoimmune diseases like rheumatoid arthritis. 2 The pain caused by these conditions can be either acute or chronic and is characterized by a diffuse or focal painful sensation in musculoskeletal or associated neural tissues. 3 In addition to pain, common symptoms of

Introduction: Prevalence and burden of headache disorders in real-world settings is relatively unstudied. We explored the associations between passively collected activity data, headache burden, and quality of life in headache sufferers.Methods: Data from wearable activity tracking devices and daily short questionnaires were collected over 12 weeks to assess occurrence of headache, activity, quality of life and self-rated health. Variables were analyzed using a series of mixed-effects models and stratified based on headache type. Multiple linear and logistic regressions were used to analyze treatment preferences.Results: Behaviors inferred from activity tracker data suggested that individuals slept more, had reduced physical activity, and had lower maximum heart rate on days with headache. As headache-specific impact on quality of life increased, activity and maximum heart rate decreased and sleep increased. Headache days with higher self-rated health were associated with less napping, higher step count and maximum heart rate, correlating with increased activity. Migraineurs experienced greater burden in everyday life compared with tensiontype headache sufferers. Conclusion: This study adds to existing evidence that activity trackers can be used to quantify headache burden in real-world settings and aid in understanding symptom management.

El dolor de cabeza es una de las principales causas de limitación en la vida cotidiana y/o de incapacidad laboral en todo el mundo. El 50% de los afectados nunca acuden a un médico, sino que recurren a la automedicación. Un consenso de expertos publicado recientemente ha investigado este fenómeno con más detalle y lo ha asociado a un concepto científico denominado «dolor de cabeza del siglo XXI».

International guidelines are commonly integrating complementary and integrative approaches into the management of musculoskeletal pain. This improves overall well-being while concomitantly reducing the reliance on conventional pharmacological treatments and the associated risk of side effects.
