Nacksmärta : Styrketräningens effekt på nacksmärta - en litteraturstudie

Sammanfattning: Background: Neck pain has a prevalence at 15-30 % in diffrent populations with diffrent causes like whiplash or tension in the muscle. It has proven a positive association between reduced pain and inhibiting the endorphin systems with physical activity. No recent review has been made since 2015, so there was a need to compile recent studies in the field.  Objective: Searches for litterature were made in the databses PubMed, PEDro and CINAHL to find randomized controlled studied that investigated strengthening training of the neck and the thoracal part of the back in persons with neckpain. All of the included articles were appraised by the PEDro-scale and the level of reliability was graded using GRADEstud.  Results: Six studies were included in this review with 382 participants. In one of six studies a significant between group diffrence was seen, the results should be discussed according to the studie's diffrent intervention/control groups. Three studies showed high quality and three showed moderate quality according to PEDro-scale. The grading in evidence showed that strengthening training of the neck and the thoracic back as treament for neckapin has a high level of evidence (++) to not reduce pain according to GRADEstud. The variation in population and time resulted in point deduction for lack of precision.  Conclusion: The results shows that strengthening training of the neck and the thoracic back does not reduce neckpain. Only one of six studied could show a significant between group diffrence. According to GRADEstud a high level of evidence is shown that the treatment dose not give effekt. The results of this study should be drawn with caution due to a low number of studies and the lack of precision in the interventions.
