BACKGROUND: Chronic musculoskeletal pain (CMP), Generalized Joint Hypermobility (GJH) and pain-related fear have influence on physical functioning in adolescents.AIM: to evaluate differences in physical functioning between adolescents with CMP, GJH or the combination of both, and in addition evaluate the potential contribution of pain-related fear.DESIGN: The design of this study was observational and cross-sectional.SETTING: The adolescents with CMP were recruited by a physician in rehabilitation medicine and measured in the university outpatient rehabilitation clinic (Adelante/Maastricht University Medical Center+, the Netherlands). The adolescents without CMP were recruited in the Southern area of the Netherlands and measured in the university outpatient rehabilitation clinic (Adelante/Maastricht University Medical Center+, the Netherlands).POPULATION: Four subgroups of adolescents were included; 21 adolescents with CMP without GJH, 9 adolescents with CMP and GJH, 51 adolescents without CMP without GJH, and 11 adolescents without CMP with GJH.METHODS: Outcome measures were muscle strength and endurance, motor performance, physical activity level, and pain-related fear. Hierarchical regression analyses were used to study differences in physical functioning and the contribution of pain-related fear in adolescents with/without CMP as well as with/without GJH.RESULTS: Adolescents with CMP had decreased muscle strength (P=0.01), endurance (P=0.02), and lower motor performance (P<0.01) compared to adolescents without CMP. Higher levels of pain-related fear were related to decreased muscle strength (P=0.01), endurance (P<0.01), and motor performance (P<0.01). No differences in physical functioning and pain-related fear between hypermobile and non-hypermobile adolescents with CMP were found.CONCLUSIONS: Adolescents with CMP had decreased muscle strength and motor performance associated with increased levels of pain-related fear compared to adolescents without CMP. The association of being hypermobile with physical functioning is not more pronounced in adolescents with CMP.CLINICAL REHABILITATION IMPACT: No differences were found in physical functioning and pain-related fear between hypermobile adolescents with CMP compared to non-hypermobile adolescents with CMP. Future rehabilitation treatment in hypermobile adolescents with CMP should also focus on psychological components, such as pain-related fear.
Corona en de intelligente lock down heeft grote invloed op het beweeggedrag van mensen en de daarmee samenhangende consequenties voor de fysieke en mentale gezondheid, het immuunsysteem etc. Fitbit beschrijft in een blog op haar website de wereldwijde afname van lichamelijke activiteit afgemeten aan het aantal stappen per dag: Europese landen laten eind maart 2020 een afname zien die varieert van 7% tot 38%. Uiteraard ligt in eerste instantie de hoogste prioriteit bij het bestrijden van COVID-19, maar inmiddels vragen overige nadelige gevolgen van Corona ook aandacht. Een daarvan is de afname van de dagelijkse hoeveelheid beweging als gevolg van het aan huis gekluisterd zijn

BackgroundTranscutaneous vagal nerve stimulation has analgesic potential and might be elicited by abdominally administered low-frequency vibrations. The objective was to study the safety and effect of a combination of music and abdominally administered low-frequency vibrations on pain intensity in elderly patients with chronic musculoskeletal pain.MethodsThis trial was an international multicenter, randomized controlled pilot study. Patients at age ≥ 65 years with musculoskeletal pain for ≥ 3 months and a daily pain score ≥ 4 out of 10 were recruited at three centers. They were randomized to receive either a combination of music and low-frequency (20–100 Hz) vibrations administered to the abdomen, or a combination with the same music but with higher frequency (200–300 Hz) vibrations administered to the abdomen. Low-frequency vibrations were expected to result in pain reduction measured with a numeric pain rating scale (NRS). Patients in both groups received eight treatments of the music combined with the vibrations in three weeks. Primary outcomes were safety (Serious Adverse Events) and pain intensity measured at baseline, after the last treatment and at six weeks follow-up. Multilevel linear model analyses were performed to study group and time effects.ResultsA total of 45 patients were analyzed according to intention-to-treat principle. After 344 treatments, 1 Adverse Event was found related to the intervention, while 13 Adverse Events were possibly related. A multilevel linear model showed that the interaction effect of group by time did not predict pain intensity (F[1, 45.93] = 0.002, p = 0.97) when comparing pain intensity at baseline, after the last treatment and at follow-up.ConclusionsThe combination of music and abdominally administered vibrations was found to be safe and well tolerated by the elderly patients. However, over time, neither the low-frequency treatment group nor the high-frequency treatment group provided clinically meaningful pain relief. There is no evidence that the low-frequency treatment elicited vagal nerve stimulation.
