Abstract

Medical and Health Sciences Psychology and Cognitive Sciences
Aim: Although it is well established that lower limb joint angles adapt to walking at various speeds, limited research has examined the modifications in joint angular velocity. To examine lower limb joint angles and angular velocities in a healthy population walking at various gait speeds. Method: Thirty-six healthy adult participants underwent three-dimensional gait analysis while walking at various speeds during habitual and slowed walking. The peak joint angles and angular velocities during important phases of the gait cycle were examined for the hip, knee and ankle in the sagittal plane. Data were grouped in 0.2m/s increments from 0.4m/s to 1.6m/s to represent the range of walking speeds reported in studies of people with gait impairments. Results: For joint angles and angular velocities, the shape of the gait data was consistent regardless of the walking speed. However as walking speed increased, so did the peak joint angles and angular velocities for the hip, knee and ankle. The largest angular velocity occurred when the knee joint extended at the terminal swing phase of gait. For the ankle and hip joint, the largest angular velocity occurred during the push-off phase. Significance of the findings to allied health: This study examined how lower limb joint angular velocities change with various walking speeds. This data can be used as a comparator for data from clinical cohorts and has the potential to be used to match clinical assessment and treatment methods to joint angular velocity during walking.
