The main purpose of the study was to investigate musculoskeletal disorders and movement patterns in restaurant workers. The goal was to examine possible correlation between those two. The aim of the study was to assess possible asymmetries in the upper body.
The sample consisted of 19 adult male restaurant workers with at least 6 months of work experience. First, they filled in the Nordic musculoskeletal questionnaire (2014) to give us information about pain-related symptoms. For the upper body asymmetries and spine flexibility assessment we used ‘seated rotation test’ and two tests from the UKK (Alpha-fit test battery, 2009). Movement efficiency was assessed by the FMS (Functional movement screen) system (Cook, 2010).
Statistical analysis was performed with IBM SPSS 21.0. Differences between sides (left and right hand/leg) in FMS were assessed by dependent samples t-test. Independent samples t-test was used to assess lateral differences for FMS based on the hand that carries loads most frequently. To assess correlation between FMS and pain we used Somers D correlation coefficient. The confidence interval was set to 95 percent.
We found that the main source of musculoskeletal problems originated from lower and upper back, knees, ankles/feet and shoulders. Insufficient level of movement efficiency was observed as the average total score was 13,97 ± 1,99. There is low or moderate correlation between musculoskeletal disorders (neck, arms, knees, elbows and wrists) and specific FMS tests (in-line lunge, rotary stability, trunk stability push up, active straight leg raise) score. No statistical significance was recorded in upper body side rotation; but a good spine related flexibility was recorded.
Results and findings of the research could be used as a tool for professionals that provide physical activity programs in observed population.
