title: The effects of head movement and walking speed on gait parameters in patients with chronic neck pain.
abstract: It has been documented that neck pain can influence sensorimotor function. However, little is known about the effects of head movement and walking speed on gait characteristics in patients with neck pain. The aim of this study was to determine gait characteristics of patients with neck pain during walking with different head movements and gait speeds as compared to a control group without neck pain. Twenty women aged between 18 and 59 years with chronic neck pain (>3 months) and 20 healthy controls of similar age, weight and height were recruited into the study. Participants with neck pain completed the Neck Disability Index and Visual Analogue Pain Scale. The experiment consisted of two walking sessions. The first session included walking with head straight, head up-down, and head turns from side to side. The second session included walking at comfortable and maximum speeds. Each trial was performed twice. Gait parameters measured using GAITRite walkway system were step length, stride length, step time, stride time, step width, cadence and gait speed. Patients with chronic neck pain demonstrated a narrower step width, a shorter step length and a slower gait speed during walking with the head movements and at maximum speed compared to the control group (all p < 0.05). Maximum gait speed was moderately correlated with pain intensity and disability (p < 0.01). The results suggest that patients with chronic neck pain have gait disturbances. This supports the notion that assessment of gait should be addressed in patients with persistent neck pain.
