Perceived pain before and after three exercise programs – a controlled clinical trial of women with work-related trapezius myalgia
Abstract The effect of exercise on neck – shoulder pain was studied in 103 women with work‐related trapezius myalgia r and omized into three exercise groups and a control group . One group trained strength , the second muscular endurance and the third co‐ordination . The exercise groups met three times weekly for 10 weeks . Pain assessment was made on three visual analogue scales , indicating pain at present , pain in general and pain at worst . Pain thresholds were measured in the trapezius muscle with a pressure algometer . A pain drawing was completed . The rated pain decreased significantly ( P<0.05 ) on the VAS describing pain at worst in the strength and endurance groups . Pressure sensitivity decreased significantly ( P<0.05 ) in four triggerpoints in the exercise groups . No changes were seen in the extent of painful body area in any group . Comparison of exercisers ( n=82 ) and controls ( n=21 ) showed significantly larger pain reductions on VAS pain at present and VAS pain at worst among exercisers . All three exercise programs showed similar decreases of pain which indicates that the type of exercise is of less importance to achieve pain reduction
