“You needed to accept the situation”:Resilience of nursing home residents in times of COVID-19

The restrictive measures taken by nursing homes during the COVID-19 outbreak in 2020 (e.g., quarantine) may have been important stressors for which residents needed resilience to safeguard their well-being. Based on 30 semi-structured interviews with nursing home residents and close relatives, this study explored the lived experiences with respect to the restrictive measures. The data were collected in psychogeriatric, somatic, and mixed wards in The Netherlands and Flanders, Belgium. The restrictive measures were important stressors for residents, indicated by feelings of loneliness, sadness, and powerlessness. To deal with these measures, residents used various resources, which were determined by factors in the individual (e.g., health), interactional (e.g., possibilities for social interactions) and contextual (e.g. nursing home policy) domains. Because the lived experiences with respect to the restrictive measures seemed to relate to the resilience of nursing home residents, it is crucial to reinforce resources in the individual, interactional, and contextual domains

Is maximal muscle strength and fatigability of three lower limb muscle groups associated with walking capacity and fatigability in multiple sclerosis? An exploratory study

Background: Both muscle fatigability and walking fatigability are prevalent in persons with MS (pwMS), but their associations remains unclear. The aim of this study was to examine the association of muscle strength and fatigability from both isometric and concentric protocols of three different muscle groups, and their association to walking capacity and walking fatigability.Methods: Twenty-seven pwMS and 13 Healthy Controls (HC) were included in this exploratory study. All par-ticipants performed a six-minute walking test (6MWT), where the distance walked index (DWI) was calculated to measure walking fatigability with a cut-off score of-10%. In three different muscle groups (knee extensors (KE), knee flexors (KF), ankle dorsiflexors (DF)), isometric and concentric muscle fatigability protocols (FIisometric or FIconcentric) were used to quantify maximal voluntary contraction (MVC) and muscle fatigability. Pearson or Spearman correlation coefficients and linear regression models were calculated to establish the association be-tween muscle strength/fatigability and walking capacity/fatigability.Results: Higher MVCs values for all muscle groups were found in HC compared to pwMS (mainly those having walking fatigability) (p < 0.05). FIisometric of DF was lower in pwMS having walking fatigability compared to no walking fatigability. MVC of KE, KF and DF had a low to moderate association with walking capacity (range r = 0.52-0.56; p < 0.05) and walking fatigability in pwMS (range r-r(s): 0.39-0.50; p<0.05). FIconcentric of KF and DF, but not of KE, were associated with walking fatigability (r = 0.39 and rs = 0.47, respectively; p < 0.05). In contrast, FIisometric for all muscle groups were not related to walking capacity or walking fatigability.Conclusion: MVC of KE, KF and DF are associated with walking capacity and walking fatigability, while concentric (but not isometric) muscle fatigability of KF and DF are associated with walking fatigability

Reliability and validity of the Dutch physical activity questionnaires for children (PAQ-C) and adolescents (PAQ-A)

BACKGROUND: This study was designed to validate the Dutch Physical Activity Questionnaires for Children (PAQ-C) and Adolescents (PAQ-A). METHODS: After adjustment of the original Canadian PAQ-C and PAQ-A (i.e. translation/back-translation and evaluation by expert committee), content validity of both PAQs was assessed and calculated using item-level (I-CVI) and scale-level (S-CVI) content validity indexes. Inter-item and inter-rater reliability of 196 PAQ-C and 95 PAQ-A filled in by both children or adolescents and their parent, were evaluated. Inter-item reliability was calculated by Cronbach’s alpha (α) and inter-rater reliability was examined by percent observed agreement and weighted kappa (κ). Concurrent validity of PAQ-A was examined in a subsample of 28 obese and 16 normal-weight children by comparing it with concurrently measured physical activity using a maximal cardiopulmonary exercise test for the assessment of peak oxygen uptake (VO(2) peak). RESULTS: For both PAQs, I-CVI ranged 0.67-1.00. S-CVI was 0.89 for PAQ-C and 0.90 for PAQ-A. A total of 192 PAQ-C and 94 PAQ-A were fully completed by both child and parent. Cronbach’s α was 0.777 for PAQ-C and 0.758 for PAQ-A. Percent agreement ranged 59.9-74.0% for PAQ-C and 51.1-77.7% for PAQ-A, and weighted κ ranged 0.48-0.69 for PAQ-C and 0.51-0.68 for PAQ-A. The correlation between total PAQ-A score and VO(2) peak – corrected for age, gender, height and weight – was 0.516 (p = 0.001). CONCLUSIONS: Both PAQs have an excellent content validity, an acceptable inter-item reliability and a moderate to good strength of inter-rater agreement. In addition, total PAQ-A score showed a moderate positive correlation with VO(2) peak. Both PAQs have an acceptable to good reliability and validity, however, further validity testing is recommended to provide a more complete assessment of both PAQs.
