Clinical measurements of spinal mobility, static balance, and functional performance in healthy participants: a simple biokinesiological analysis of performance

[Purpose] To explore the relationship between functional outcome measurements of spinal mobility, static balance and functional performance. [Participants and Methods] Fifty two healthy participants aged between 18–36 years participated. Spinal mobility included forward bending and side bending. Balance was tested via maintaining single-leg stance position with eyes open and with eyes closed. Functional testing included five times squat to stand, walking on heels and walking on tiptoes. [Results] Two-way mixed intraclass correlation coefficients (ICCs) consistency model average measure (ICC(3,K)) for single-leg standing with the eyes are open and closed was excellent (0.85) and very good (0.79) respectively. Mean forward spinal mobility score of the recreationally active group (M= 3.3 ± 5.7) was significantly lower (M= 9.5 ± 10.5) than inactive group. Regarding five times squat to stand, the mean score of the recreationally active group (10.4 ± 4.3) was not significantly different from the mean of the recreationally inactive group (9.5 ± 2.6). [Conclusion] Walking on heels significantly took more time and perceived with more exertion than tiptoes walking. Also, standing on one leg was harder when eyes are closed. Recreationally active had shown significant forward mobility but no difference between sidebending mobility. The relationships between different outcome measures need to be furtherly explored.
