“…However, few studies have demonstrated how GRFs are affected in the anteroposterior axis during GI after stroke (Tokuno and Eng, 2006;Brunt et al, 1995;Bensoussan et al, 2006). Further, only one of these studies has demonstrated how GRFs are affected in the mediolateral axis (Brunt et al, 1995).…”

“…Using kinematics, foot drop was determined by measuring toe elevation ( Fig. 3a; Bensoussan et al, 2006;Chin et al, 2009;Weber et al, 2004). This measure was correlated with overground speed, the patients having the lowest toe elevation taking a longer time to walk 10 m (Fig.…”

“…Maximum toe elevation has been used previously [17][18][19] and is a simple measurement for culling out the effect of CST lesion on gait function. It clearly reflected CST impairment, although compensations used by the participants to overcome foot drop were probably not completely excluded from those measurements.…”

Objective: Maximum toe elevation during walking is an objective measure of foot drop and reflects the impairment of the corticospinal tract (CST) in persons with spinal cord injury (SCI). To determine if this measurement is functionally relevant to ambulatory abilities, we correlated maximum toe elevation with clinical physiotherapy tests. Setting: Cross-sectional study, laboratory and clinical settings. Methods: A total of 24 individuals with SCI (American Spinal Injury Association (ASIA) Impairment Scale D) were recruited. Maximum toe elevation during the swing phase of treadmill gait was measured with a kinematic system. CST function was assessed in a sitting position by measuring the motor-evoked potentials (MEPs) induced in tibialis anterior muscle with transcranial magnetic stimulation over the motor cortex. Clinical tests performed were 10-m and 6-min walk test (6MWT), Timed-Up and Go (TUG), Walking Index for Spinal Cord Injury, Berg Balance Scale, Lower Extremity Motor Score (LEMS) and sensory score of the L4, L5 and S1 dermatomes. Results: Participants with lower toe elevation during gait walked at a slower speed, took more time to perform the TUG test, and covered a shorter distance in the 6MWT. They also scored lower on the LEMS and showed impaired superficial sensitivity of the dermatomes around the ankles. Few correlations were observed between CST function and clinical tests, but the presence of MEP at rest was indicative of faster speed and longer distance in the 6MWT. Conclusion: These results indicate that maximum toe elevation, which is directly correlated with CST impairment, is functionally relevant as it also correlates with timed clinical tests, LEMS and sensory scores. induced by TMS reflects impaired transmission in CST. Although CST transmission is increased following specific interventions, 1,2 correlation between MEP characteristics and overall gait function is not all that clear. While motor function can remarkably improve during recovery, MEP latency remains pathologically prolonged. 3 Also, a recent study demonstrated lack of correlation between measures of MEPs and gait. 4 One reason might be that CST involvement is more prominent in discrete subtasks of the function rather than in the overall task, which requires concurrent input from many different systems. Identifying the precise role of CST within gait will enable a more specific assessment of incapacities following CST lesion. Previous studies and clinical assessment of stroke patients indicate that the CST is involved in foot elevation during swing and that its impairment induces foot drop. [5][6][7] We have recently shown that measurement of maximum toe elevation during swing can be used as a simple and objective measurement of foot drop and reflects CST impairment in persons

Kinematic and Kinetic Asymmetries in Hemiplegic Patients’ Gait Initiation Patterns

Abstract: Quantitative data obtained on the gait initiation phase suggest that hemiplegic patients develop asymmetrical adaptive posturo-motor strategies to compensate for their impairments.
