THE RELATIONSHIP BETWEEN ORTHO HEAD POSTURE AND HEAD POSTURE MEASUREDDURING WALKING

Murphy, Preston, and Evans recognized the dynamic nature of head postu re and developed instrumentation capable of measuring and recording th is posture in a continuous manner. The aim of the current project was to use the newly developed instrumentation to determine whether the di fference is statistically significant between the mean natural head or tho posture, measured in a controlled manner, and the mean dynamic hea d posture obtained during 5 minutes of walking activity in an experime ntal situation. The mean ortho head posture and the mean walking head posture were measured in each of 30 men. The differences between these two sets of mean head postures were statistically significant (p less than or equal to 0.05). In 23 persons,the mean walking head posture w as tipped backward relative to the mean natural head ortho position.
