Scapula focused excercise in crossfit athletes with subacromial pain : a single-subject study (English)
Abstract [sv]

Bakgrund: Subacromiell smärta är vanligt hos idrottare med repetitivt arbete ovan axelhöjd, vilket kan orsakas av obalans i muskulatur, förändrad position eller inskränkt rörlighet av scapula. Nedsatt funktion av scapula och dess stabilitet kan leda till minskad axelledsrörlighet och försvagad muskultur i området. Träning är förstahandsalternativet för minskad smärta, förbättrad funktion och ökad rörlighet vid subacromiell smärta. Behandling med scapulafokuserad träning har i dagsläget otillräcklig evidens. Mer studier behövs för att avgöra vilken nedsättning av scapula som den typ av träning påverkar och hur olika scapula fokuserade interventioner påverkar subacromiell smärta.

Syfte: Syftet med studien var att undersöka effekten av kombinationsövningen ”shoulder dislocations” vad gäller scapulakontroll, aktiv utåtrotation i axelled och smärta hos crossfitutövare med subacromiell smärta.

Metod: Single-subject metod med AB design användes till studien. Tre baslinjemätningar och fyra mätningar under interventionsfasen gjordes, där scapulakontrollen och aktiv utåtrotation i axeln mättes samt smärtskattning utfördes. Deltagarna var sin egen kontroll. Populationen var personer som tränade crossfit vid minst tre tillfällen per vecka med subacromiell smärta. Under interventionen utför deltagarna ”shoulder dislocation” tre gånger per vecka med doseringen tio repetitioner i tre set. Resultatet presenterades i grafer och analyserades visuellt.

Resultat: Fyra deltagare inkluderades i studien varav en med bilaterala besvär. Samtliga deltagare förbättrade scapulakontrollen, fyra av fem deltagare förbättrade den aktiva utåtrotationen i axelled. Tre av fem deltagare upplevde minskad smärta under träning och vid mättillfället.

Slutsats: ”Shoulder dislocation” tycks förbättra scapulakontrollen, aktiv utåtrotation i axelleden hos crossfitutövare med subacromiell smärta och tendens till minskad smärta.

Abstract [en]

Background: Subacromial pain is common among overhead athletes, which can lead to muscular imbalance, changed position or decreased mobility of scapula. Reduced function and stability of scapula could lead to decreased shoulder mobility and weakened musculature in the area. Exercise is first hand choice to reduce pain, improve function and increase range of motion at subacromial pain. Treatment with scapular focused exercise is today limited. More studies are needed to determine what kind of reduction of scapula this exercise influences and how different scapular focused interventions affect subacromial pain.

Aim: The purpose of the study was to examine the effect of the combination exercise ”shoulder dislocations” in terms of scapula control, active external rotation in the glenohumeral joint and pain in crossfit athletes with subacromial pain.

Method: Single-subject method with AB design was used in the study. Three baseline measurements and four measurements during the intervention phase was collected, where control of scapula, active external rotation and pain was measured. Participants were their own control. The population was individuals who trained crossfit at least three times a week and had subacromial pain. During the intervention the participants performed ”shoulder dislocations”. Performing three sets of ten repetitions three times a week. The results were presented in graphs and visually analyzed.

Results: Four participants were included in the study whereof one had bilateral disorders. All participants increased control of scapula, four out of five increased active external rotation of the glenohumeral joint. Three out of five participants experienced pain reduction during exercise and at the time of measurement.

Conclusion: ”Shoulder dislocations” seems to improve control of scapula and active external range of motion of the glenohumeral joint in crossfit athletes with subacromial pain.
