Compensatory Exercise with Dual-Task using Kommo® for People with Sedentary Work

Background: Sedentary work increases the risk of back pain and reduces physical capacity. Cognitive-motor (dual-task) training can influence attention, postural control, and pain perception. Objective: To evaluate the feasibility of a group compensatory exercise program using the Kommo® bar (dual-task approach) in sedentary workers and to assess its effects on spinal mobility and back pain. Methods: Fifteen participants (11 women, 4 men; aged 20–59 years, mean age 41.8; average sitting time 8.6 h/day) completed an 8-week intervention (one 60-minute group session per week). Spinal mobility was assessed using Čepoj’s distance, Ott’s distance (inclination and reclination), Schober’s distance, Stibor’s distance, and Thomayer’s test. Functional mobility was evaluated with the Five Times Sit-to-Stand test and the Timed Up and Go test (including the cognitive variant, TUGcog). Pain was assessed using the Visual Analogue Scale (VAS) and the McGill Pain Questionnaire. Data were analyzed with paired t-tests, after testing for normality with the Shapiro–Wilk test. Results: All participants completed the program without complications (0% dropout). Significant improvements were observed in thoracic spine mobility (Ott, Stibor), functional mobility (5×STS, TUG, TUGcog), and perceived back pain (VAS, McGill). Conclusion: An 8week compensatory exercise program with dual-task elements using the Kommo® bar is feasible and shows promise in reducing back pain and improving mobility in sedentary workers. Larger controlled studies are warranted.
