“…Several studies have reported increased cadence in treadmill versus matchedspeed overground gait [12][13][14]. However, in an analysis of the accommodation phenomenon, Matsas et al [14] reported that these differences vanished after only 6 min practice of treadmill walking.…”

“…Studies before instrumented treadmills examined only the kinematics of treadmill gait. The earliest studies reported small differences in overground and treadmill gait patterns [10][11][12][13]. Later work indicated that for healthy young subjects these differences vanish after an appropriate accommodation period [14].…”

“…Moreover, the results of a comparison of walking rate between comfortable backward walking and treadmill backward walking revealed a significantly lower rate for treadmill backward walking at 0.8 km/h as well as lower exercise tolerance. It is generally said that the step rate is higher and stride is lower in treadmill walking than in over-ground walking 43,44) . This is one of the problems of the transferal of forward treadmill walking to overground walking.…”

Abstract. [Purpose] We tested the efficacy of an intervention training acute stroke patients to walk backwards on a treadmill. Subjects were randomly allocated to three groups of Partial Body Weight Support treadmill backward walking group, Partial Body Weight Support treadmill forward walking group and Control in order to compare the efficacy of the interventions among the groups.[Subjects] The subjects were 36 acute stroke patients.[Methods] They were randomly allocated to the three groups using an envelope method. After 3 weeks of intervention. We investigated by multiple comparisons among the three groups using change scores for each of the outcome measures.[Results] The Berg Balance Scale showed no significant differences. The Rivermead Mobility Index showed a significant difference between the backward walking group and the forward walking group, and between the backward walking group and the Control. Walking speed was significantly different between the backward walking group and the Control. No differences were seen for other itemes.[Conclusions] As a result of 3-week intervention, a significant improvement was observed in walking speed and the Rivermead Mobility Index, suggesting that Partial Body Weight Support treadmill backward walking training for patients in the early phase of acute stroke is effective at improving mobility.

“…In fact, although a number of comparative studies did regard TW and OW as kinesiologically equivalent actions due to their highly similar biomechanical profiles (Nymark et al 2005;Riley et al 2007;Tesio and Rota 2008;Van Ingen Schenau 1980), several reports revealed significant differences between the two of them. For instance, TW was shown to entail increased cadence (Alton et al 1998;Murray et al 1985;Nymark et al 2005;Stolze et al 1997;Strathy et al 1983;Warabi et al 2005), altered knee and ankle joint kinematics (Alton et al 1998;Murray et al 1985;Strathy et al 1983) and reduced pelvis and trunk range of motion in the transverse and frontal planes (Vogt et al 2002). Significant, and in some cases notable (Lee and Hidler 2008) changes were described also for ground reaction forces (Goldberg et al 2008;White et al 1998), lower limb joint moments and powers (Lee and Hidler 2008;Riley et al 2007) and EMG activity of thigh and leg muscles (Arsenault et al 1986; Lee and Hidler 2008;Murray et al 1985;Nymark et al 2005).…”

Coordination between upper- and lower-limb movements is different during overground and treadmill walking

et al. 2009

Locomotion studies employ either treadmill (TW) or overground walking (OW), considering that differences between them are negligible. The present study tests this notion by comparing coordination between upper- and lower-limb movements in healthy individuals during OW and TW at matched speeds. Results indicated that TW induced a higher cadence, which highly influenced interlimb coordination, in terms of frequency coupling and relative phase between arm and thigh motion. At low speed, the 2:1 pattern (double arm swing per stride) displayed lower incidence in TW compared to OW, and this was correlated with a lower sagittal acceleration at the shoulders, at twice the stride frequency, in the former condition. The low occurrence of the 2:1 coupling in TW, moreover, was correlated to a preferential adoption of a cadence exceeding 80% of the arm's resonant frequency, whereas higher incidence of this pattern in OW involved a preferential cadence below the 80% threshold. Results indicated also that the relative phase between arm and ipsilateral thigh swinging was smaller in TW, in relation to an earlier occurrence of maximum thigh extension, shortened stance phase, and increased cadence. These findings suggest that arm-leg coordination is different in OW and TW, and that difference can be mainly ascribed to condition-specific setting of central mechanisms for scaling stride frequency, for controlling dynamic axial posture (sagittal shoulder acceleration), and, possibly, for maintaining inter-limb synchrony. Awareness of a different "motor set" in TW and OW is critical if data from the two paradigms are used in physiological and patho-physiological studies.
