Background: Changes in load during asymmetric holding may be associated with particularly high risk of loss of balance and spinal injury. Therefore, in order to assess occupational lesions and to make preventive rehabilitation programs in such conditions like holding dynamic loads in asymmetric postures could be important.

 

Methods:  In a cross-sectional study, COP amplitude and velocity sway were studied in 14 normal male volunteers during holding static and dynamic load in symmetric and asymmetric postures.

 

Results: Similar Anterior-Posterior responses to the postures were seen, although asymmetric postures showed a larger Medial-Lateral COP amplitude and velocity sway (p<0.05). While dynamic load increased Anterior-Posterior and Medial-Lateral postural parameters in asymmetric posture (p<0.05), we observed increase only in Anterior-Posterior direction in symmetric posture (p<0.05).

 

Conclusion: The results showed that dynamic load challenges the postural stability control, with a higher effect in asymmetric posture.
