Abstract [sv]

Introduktion: Nacksmärta är en av de vanligaste anledningarna till funktionsnedsättning med en livstidsprevalens på ungefär 50%. Få tidigare studier har undersökt sambandet mellan upplevd smärta och muskelfunktioner och dessa har använt subjektiva skattningsskalor som mått på smärtupplevelsen. Med pain pressure threshold (PPT) som mått på smärtan fås ett kvantifierbart värde med jämna skalsteg som skulle kunna användas i kliniska sammanhang.

Syfte: Främsta syftet med den här studien är att undersöka om Trapezius PPT kan förutsäga nackmuskelfunktioner och nackrörlighet hos kvinnor med kronisk nacksmärta. Andra syften är att undersöka skillnader mellan whiplashpatienter (WAD) och idiopatiska nacksmärtpatienter (INP) samt om centralsensitisering påverkar ovan nämnda funktioner.

Metod: Testpersonerna delades upp i tre grupper; kontrollgrupp (n=29), WAD (n=28) och INP (n=36). PPTs, nackmuskelstyrka, neuromuskulär kontroll, muskeluthållighet och nackrörlighet mättes hos grupperna och regressionsanalys samt skillnadstester utfördes.

Resultat: Resultaten visar flertalet signifikanta skillnader mellan kroniska WAD och INP patienter. Regressionsanalysen visar att Trapezius PPT potentiellt kan användas för att förutsäga muskelfunktioner och nackrörlighet i WAD-gruppen. Resultaten visar också att centralsensitisering har en negativ påverkan på undersökta variabler.

Konklusion:Det finns stora skillnader mellan kroniska WAD och INP patienter och framtida studier bör kanske separera dessa patienter åt och inte benämna de som kroniska nacksmärtpatienter. Den kliniska användningen av Trapezius PPT som ensam prediktor för nackmuskelfunktioner och rörlighet behöver undersökas närmare. 

Abstract [en]

Introduction: Neck pain is one of the most common causes of disability with a lifetime prevalence of approximately 50%. Few previous studies have investigated the correlation between pain and muscle functions and they’ve all used subjective self-estimated pain-rating scales as pain measurements. Pain pressure threshold (PPT) as a pain measurement gives a definite value of the pain which could be clinically useful for therapists.

Purpose: The primary purpose of this study is to examine if Trapezius PPT can predict muscle functions and cervical range of motion (CROM) in women with chronic neck pain. Other purposes are to examine differences between patients with whiplash associated disorders (WAD) and idiopathic neck pain (INP) as well as if central sensitization affects the examined variables.

Method: The subjects were devided into three groups; healthy controls (n=29), WAD (n=28) and INP (n=36). PPTs, neck muscle strengths, neuromuscular controll, muscle endurance and CROM were measured and regression analysis as well as difference tests were performed.

Result: The results show several significant differences between the WAD and INP patients. The regression analysis shows that Trapezius PPT might be used for predicting muscle functions and CROM in the WAD group. The results also show that central sensitization negatively affects the examined variables.

Conclusion: There are major differences between chronic WAD and INP patients. One might suggest to separate these groups in future studies. The clinical usability of Trapezius PPT as a single predictor for neck muscle functions and CROM needs to be further examined.
