“…However, the results were consistent with the study by Chiu & Chou (2012, 2013, which reported that decreased variability in the pattern of coordination between joints during walking appears with aging and it increases the risk of falls. In order to determine the relationship between variability and stability during exercise, additional studies that take into account various situations, such as variability variables, joints and segments, and age are needed.…”

“…Walking is a complex activity that requires multi-joint coordination and the ability to sequence joint angles and segments during motion (Rochester et al, 2008;Chiu & Chou, 2012). In healthy subjects, walking is automated and rhythmic, and limb movements are replicated from stride-to-stride while free walking (Morris, Iansek, Matyas, & Summers, 1994b).…”

This study examined the effects of concurrent walking tasks and interlocutor distance on conversational speech production in fifteen individuals with idiopathic Parkinson's disease (PD) and fourteen age-equivalent controls. Recent studies of speech in PD have demonstrated that changes in the behavioural conditions and the environmental context can have a powerful effect on the severity of speech symptoms in PD. This investigation focused on changes in speech intensity and speech rate in response to changes in walking speed and interlocutor distance. Results suggest that the introduction of a concurrent walking task significantly increased the conversational speech intensity of both controls and individuals with PD. When compared to sitting and talking or standing and talking, current walking and talking appeared to have an energizing effect on conversational speech intensity. In addition, walking faster was associated with a significant increase in conversational speech intensity relative to normal and slow walking speeds. These results provide important new information about the effect of concurrent walking on speech motor performance and speech symptom severity in PD. The potential energizing effect of concurrent walking conditions on conversational speech intensity may be an important consideration in the assessment and treatment of individuals with low speech intensity in PD.

“…Hamill et al suggested that higher gait variability at lower speeds explains how the central nervous system facilitates movement patterns to comply with changes in the walking speed (19). By comparison of gait parameters in the two groups, low to average reliability levels in some parameters at low walking speed seem to be due to the preferred walking speed.…”

“…Walking speed, as well as testing condition and the subjects characteristics are believed to affect join motion, and therefore the reliability of its kinematics (19,20). Most importantly, reliability of registered kinematic parameters is not the same in all conditions and diseases (21,22).…”

Background: Reconstruction surgery is one of the treatment methods after an anterior cruciate ligament (ACL) injury especially in athletes. Reconstructed ACL is associated with altered joint biomechanics, abnormal muscle strength, gait disorder and decreased athletic performance. Abnormal walking pattern has been shown to be one of the functional consequences of ACL reconstruction. Objectives: The aim of this study was to investigate the reliability of kinematic and spatiotemporal gait parameters after ACL reconstruction using Zebris ultrasound movement analysis system. Methods: A sample of convenience including 20 healthy athletes and 20 athletes 4 to 6 months after ACL reconstruction participated. Subjects walked on a treadmill for one minute at preferred, high and low speeds and kinematic and spatio -temporal parameters including stride time, stride length, maximum knee flexion, maximum knee flexion velocity and maximum knee extension velocity are calculated. Results: In the patient group, relative reliability measures for almost all parameters were high at low (ICC: 0.7 -0.97), preferred and high speeds (ICC: 0.75 -0.97). This was also true for the control group, were reliability for all parameters was high at low, preferred (ICC: 0.74 -0.99) and high (ICC: 0.83 -0.99) speeds, except for stride time of the left leg which showed moderate reliability. Additionally, at high speed, all parameters revealed very high reliability. Conclusions: Zebris movement analysis system is a highly reliable instrument for the measurement of gait parameters at different speeds in healthy athletes and those after ACL reconstruction surgery. This implies its use in the assessment and treatment process of gait deficits in such a clinically important population.
