segmentary mechanical work as a new instrument to postural control evaluation

Objectie: Calculate the mechanical work (W), applying the total mechanical work (Wtot) and segmental work (Wseg) as a new complementary evaluation resource of the postural control mechanisms in subjects undergoing motor and visual disturbance. Methods: Ten healthy adult male volunteers were selected with ages 25.6 (±2.26) years, whose height was 1.69 (± 0.25) m and body weight was 68.22 (± 0.25) kg. Kinematic data of trunk extension with eyes open and blindfolded were captured with a frequency of 200 Hz. This way the post perturbation interval has been selected and the Wseg (i.e. trunk, head, etc) and the total mechanical work (Wtot) calculated, which were obtained by means of total integral mechanical energy. Results: The statistical analyzing of information was done by paired-data Student's t test. There has been no significant difference (p
