Reliabilitetstest av Biodex multi-joint system III för mätning av passiv muskelstelhet i vaden

Spasticitet, kontrakturer och muskelstelhet kan orsaka nedsatt rörlighet i leder. Ett stort antal behandlingsmetoder för att förbättra rörligheten i leder och muskler används. Resultaten av dessa behandlingsmetoder har visat skiftande verkningsgrad, vilket ökar intresset för att ta fram mer avancerade mätmetoder med ökad tillförlitlighet. Syftet med studien var att reliabilitetstesta en Biodex multijoint system III för mätning av passiv muskelstelhet i vadmuskulaturen. Åtta män (29±5) år och tolv kvinnor (24±3) år, deltog i studien.

Äldre personers attityd till styrketräning: utformning och reliabilitetstestning av en provenkät

Syftet med denna studie var att utforma och reliabilitetspröva enkätfrågor om äldre personers attityd till styrketräning. En enkät bestående av 47 frågor och påståenden delades ut till 31 äldre (60-81 år) personer som fick besvara enkäten vid två separata tillfällen. Varje enskild fråga analyserades för test-retestreliabilitet på tre olika sätt: 1/ Intraclass correlation coefficient (ICC) 2/ Absolut reliabilitet med 80% respektive 95% konfidensnivå samt 3/ Proportion of agreement (PA) med PA% och PA ±1%. Enligt gränsvärden som sattes för acceptabel reliabilitet hade 16 frågor ett värde på ICC <0,50, 11 frågor ett pa(%) <60%, 16 frågor ett värde &lt;80% på pa ±1%, nio frågor en absolut reliabilitet av =>2,0 vid 95% säkerhet och 12 frågor en absolut reliabilitet =>1,5 vid 80% säkerhet. Dessutom visade analysen av absolut reliabilitet att det för 2/3 av frågorna krävs två skalsteg för att påvisa en skillnad vid 95% säkerhet.

Förberedande läpprundning hos personer som stammar : EMG-studier av stamning och flytande tal

Vid afasi påverkas förmågan att samtala och interagera med andra människor i varierande grad. Omgivningen kan utgöra en stor skillnad för hur personen med afasi lyckas interagera med hjälp av olika slags stöd, t ex med skrivet material som förstärkning till samtalsinnehållet. Aura Kagan har inom ramen för samtalsmodellen SCA (Supported Conversation for Adults with Aphasia) utformat ett bedömningsmaterial för konversationsförmåga hos personer med afasi och deras konversationspartners. Detta bedömningsmaterial har i den här studien använts som utgångspunkt för utformningen av ett svenskt bedömningsmaterial för konversationsförmåga som är ämnat att användas vid vårdinrättningar som rehabiliterar personer med afasi. Sex logopeder använde det framtagna materialet för att bedöma konversationsförmågan dels hos tio personer med varierande karaktär och svårighetsgrad av afasi, dels hos deras konversationspartners.

Hematologiska analysinstrument för mindre djurkliniker : en utvärdering av QBC-V och Scil Vet abc för analys av prover från hund och katt

Two haematological instruments intended for small animal clinic use were evaluated at the Department of Clinical Chemistry, Swedish University of Agricultural Sciences (SLU), Uppsala, Sweden. The QBC-V and Vet abc were compared to a reference instrument, the Cell-Dyn 3500. Fresh blood samples were obtained from canine and feline patients from the University Veterinary Hospital, SLU.

Skiftarbetets påverkan på den upplevda stressen : - en undersökning inom vården

AbstractThe purpose with this study was to get knowledge if there are any possible differences in, and correlation between, experienced stress, experienced demands, experienced control and experienced social support in correlation to shiftwork.The study was made at two central hospitals in south of Sweden and had 90 participants (78 women and 12 men) that answered a questionnaire in the current variables. The result in experienced stress showed that there were no differences between shift workers. The results showed a difference between the day- and the nightshift in the correlation between control and stress. The writers speculates that the reason why the nightshift experience high stressvalues with high control can depend on the lack of presence by higher managers, compared with the dayshift. .
