Assessment of gait mechanics and muscle strength in hypermobile Ehlers Danlos Syndrome.

BACKGROUND: Hypermobile Ehlers Danlos Syndrome, a heritable connective tissue disorder, is associated with muscle dysfunction, joint subluxations and pain. The impact of hypermobile Ehlers Danlos Syndrome on musculoskeletal mechanics is understudied. Therefore, the aim of this study was to assess the effects of hypermobile Ehlers Danlos Syndrome on lower extremity gait mechanics and muscle strength. METHODS: Eleven people with hypermobile Ehlers Danlos Syndrome and 11 asymptomatic controls underwent a 3D gait analysis and isometric hip and knee muscle strength assessment. Joint subluxations were self-reported by the hypermobile Ehlers Danlos syndrome group. Independent t-tests and Mann Whitney U tests were used to analyze joint mechanics, muscle strength, and patient report outcomes (p < 0.05). FINDINGS: Both groups exhibited similar walking speeds as well as similar hip, knee, and ankle joint kinematics. The hypermobile Ehlers Danlos Syndrome group walked with a lower peak hip extensor moment (hypermobile Ehlers Danlos Syndrome: -0.52 ± 0.28 Nmˑkg-1, Control: -0.83 ± 0.26 Nmˑkg-1, p = 0.01) yet similar knee and ankle joint moments. The hypermobile Ehlers Danlos Syndrome group exhibited a 40% deficit in peak hip extensor strength (hypermobile Ehlers Danlos Syndrome:1.07 ± 0.53 Nmˑkg-1, Control: 1.77 ± 0.79 Nmˑkg-1, p = 0.04). Approximately 73%, 55% and 45% of the hypermobile Ehlers Danlos Syndrome cohort self-reported hip, knee/patella and ankle joint subluxations, respectively, at least once a week. INTERPRETATION: Patients with hypermobile Ehlers Danlos Syndrome ambulated with altered hip extensor moments and exhibit hip extensor weakness. Future work should investigate the underlying mechanisms of hip extensor weakness and corresponding effects on joint health in people with hypermobile Ehlers Danlos Syndrome.

The Development of Palliative Care in Argentina: A Mapping Study Using Latin American Association for Palliative Care Indicators.

BACKGROUND: The Latin American Association for Palliative Care (ALCP) developed 10 indicators to monitor the development of palliative care. The indicators have been applied across Latin American countries but have not been used internally. OBJECTIVE: The aims of this study were to document the development of palliative care in Argentina at the national and provincial levels by using a selection of the indicators developed by the ALCP and identify the difficulties and needs of healthcare professionals working in palliative care. This is the first study to apply the indicators intranationally. METHODS: This was a cross-sectional pilot study based on two questionnaires with representatives from each province, one workshop, and telephone conversations to corroborate the collected data. These data were used to calculate a preselection of eight ALCP indicators covering four main areas of development: education, policy, service delivery, and medication. A total of 30 participants took part in the study. RESULTS: The application of the ALCP indicators at the province level led to the identification of inequalities in the development and distribution of services across the country. The provinces in the north-west were identified as the region with the greatest need for development. The main difficulties for healthcare professionals were lack of national service registries, certified palliative care specialties, and opportunities for continuous training. DISCUSSION: The ALCP indicators are useful tools for mapping palliative care development within countries. Further work needs to be carried out to increase their specificity and integrate them in policy design and service delivery.
