“…This may have affected our results to some extent but the differences are likely to be very small. Indeed, the limited number of EMG studies that have compared treadmill walking and floor walking failed to show clear differences in the underlying patterns of muscle activity, other than minor changes in the amplitude of muscle activity [16,17]. While these studies did not extend to the very low speed range it is unlikely that major differences would appear.…”

Speed related changes in muscle activity from normal to very slow walking speeds den Otter, Rob; Mulder, T.; Duysens, J.

For technical reasons the number of authors shown on this cover page is limited to 10 maximum. AbstractThe study of neuromuscular activity at very slow walking speeds may lead to a better understanding of the mechanisms underlying speed regulation during walking, and may aid the interpretation of gait data in patients who walk slowly. Extreme reductions in walking speed will cause changes in locomotor task demands that may eventually result in modifications of the patterning of muscle activity that underlies walking. The aim of the present study was to investigate patterns of lower limb muscle activity during very slow walking (< 0.28 m s −1 ), and to study the neuromuscular gain functions that reflect the phase dependent effects of walking speed on electromyographic (EMG) amplitude. Nine healthy young adults walked at seven different walking speeds (1.39, 0.83, 0.28, 0.22, 0.17, 0.11, and 0.06 m s −1 ) while EMG was recorded from eight lower extremity muscles. Results showed that the phasing of muscle activity remained relatively stable over walking speeds despite substantial changes in its amplitude. However, between 1.39 and 0.28 m s −1 , epochs of Rectus femoris, Biceps femoris and Tibialis anterior activities were found that were typical for specific speed ranges. When walking speed decreased further to almost standing still (0.06 m s −1 ), negative gain values were found in Peroneus longus during midstance and Rectus femoris in late swing, indicating the emergence of new bursts of activity with decreasing walking speed. It is proposed that these extra activities may be attributed to increased demands on postural stability, and the altered dynamics of the swinging limb at very slow speeds.

“…This pattern can adapt easily to different speeds, 15,17 inclines, [30][31] surfaces such as overground versus treadmill [32][33][34][35] and uneven surfaces. 36 The main objective of the present study was to measure how SCI subjects adapt to changes in the walking speed.…”

Treadmill walking in incomplete spinal-cord-injured subjects: 1. Adaptation to changes in speed

2003

Walking in spinal-cord-injured (SCI) subjects is usually achieved at a lower speed than in normal subjects. Study design/methods: Time and distance parameters, angular displacements of lower limbs and electromyographic (EMG) activity were measured for seven normal and seven SCI subjects at several walking speeds. Analyses of variance were used for comparing groups and speeds. Objectives: First, to measure the adaptability of SCI subjects' walking pattern to different speeds (0.1-1.0 m/s), and to compare it to that of normal subjects. Second, to characterize SCI subjects' walking pattern as compared to that of normal subjects at a matched treadmill speed (0.3 m/s). Setting: University-Based Human Gait Laboratory, Montreal, Canada. Results: SCI subjects' pattern adapted to a limited range of speeds. Longer cycle duration, flexed knee at foot contact, increased hip joint flexion at foot contact and during swing, and altered coordination of hip and knee joints were found for the SCI group. At all speeds, duration of muscle activity was longer in the SCI group and the increase in amplitude of soleus EMG activity at higher speeds was not specific to push-off. The importance of matching the walking speed of SCI and normal subjects in order to differentiate the features that are a consequence of SCI subjects' reduced walking speed rather than a direct consequence of the injury is demonstrated. Conclusions: All SCI subjects could adapt to a narrow range of speeds and only three could reach the maximal tested speed. This limited maximal speed seems to be a consequence of SCI subjects having reached their limit in increasing stride length and not being able to increase stride frequency further. This limitation in increasing stride frequency is likely because of the altered neural drive. Sponsorship: Neuroscience Network of the Canadian Centre of Excellence.

“…While Ralston [39] reports that TJ and floor walking are metabolically the same, no consensus exists with regard to whether the results from treadmill walking accurately represent overground walking. Some studies reported that walking on a treadmill versus a floor differ kinematically [40] and metabolically [41,42]. The current study is a comparison between SJT and TJ with different floor conditions, and TJ may not be synonymous with jogging on the floor (slow jogging).…”
