The profiles of the linear envelopes of surface electromyograms of seven major muscles in adults were studied as a function of walking speed. The ensemble statistical properties of average and standard deviation were used to quantitate the characteristics of the electromyographic patterns. Analysis of variance was used to indicate periods in the gait stride that were effected by walking speed. ...

Many falls in older adults occur during walking following trips. Following a trip, older adults take longer than younger adults to recover steady-state walking. Although faster gait speed may improve interlimb coordination, it may also increase fall risk in older adults. We hypothesized that older adults would take longer than younger adults to recover from an unexpected perturbation during gai...

This study compared the kinematic and electromyographic (EMG) gait patterns of able-bodied adults at natural speed in contrast to extremely slow overground and treadmill walking speeds. Kinematic and EMG data were collected at three speeds (self-selected, 0.30 m/s, and 0.20 m/s). Eighteen subjects were evaluated for trunk and lower-limb motion and EMG of five lower-limb muscles. Significant red...

OBJECTIVE To determine the factors associated with gait parameters in female patients with rheumatoid arthritis (RA). METHODS The gait analysis was performed in a large cohort of RA patients, and three basic gait parameters (step length, cadence and gait speed) were calculated. Clinical and laboratory data were also collected. Factors associated with gait parameters were analyzed using multiv...

BACKGROUND Lack of participation in cardiac rehabilitation (CR) and slow gait speed have both been associated with poor long-term outcomes in older adults after acute myocardial infarction (AMI). Whether the effect of CR participation on outcomes after AMI differs by gait speed is unknown. METHODS AND RESULTS We examined the association between gait speed and CR participation at 1 month after...

objectives: this study was designed to evaluate the effectiveness of a modified floor reaction ankle foot orthosis (frafo) design on gait performance in children with cerebral palsy. methods: eight children with cerebral palsy wore a modified frafo bilaterally for six weeks. motion analysis was used to assess the immediate effectiveness of the orthosis on improving gait and also following six w...

BACKGROUND The relationship between executive functions (EF) and gait speed is well established. However, with the exception of dual tasking, the key components of EF that predict differences in gait performance have not been determined. Therefore, the current study was designed to determine whether processing speed, conflict resolution, and intraindividual variability in EF predicted variance ...

OBJECTIVE To compare the effects of speed-dependent treadmill training on gait and balance performance in patients with sub-acute stroke. DESIGN Single-blinded randomized controlled trial. SUBJECTS A total of 26 patients with sub-acute stroke were randomly assigned to experimental (n = 13) and control (n = 13) groups. METHODS Subjects in the experimental group underwent short interval wal...
