Rehabilitation of gait after stroke: a review towards a top-down approach. 16, 14–21. Front. In the Fast walker group, a stroke survivor has ~44% of a normal walking speed. We also observed GM activation beginning in the swing phase. There are also some plantarflexors contracture and spasticity to provide necessary ankle stability. 80, 26–32. Gait analysis: clinical facts. The influence of stance-phase knee flexion on the vertical displacement of the trunk during normal walking. Three pt gait pattern. gait analysis evaluation of the manner or style of walking, usually done by observing the individual walking naturally in a straight line. doi: 10.1136/jnnp.57.7.773, Burke, D., Wissel, J., and Donnan, G. A. It is usually achieved and maintained without conscious awareness and cognitive processing. doi: 10.1016/j.jbiomech.2014.02.002, McGowan, C. P., Neptune, R. R., Clark, D. J., and Kautz, S. A. doi: 10.1016/j.apmr.2013.11.008, Ting, L. H., and McKay, J. L. (2007). Botulinum toxin therapy is often used for spasticity management of leg muscles to improve gait (Esquenazi et al., 2015; Baker et al., 2016). 2016; 20(1):65-73. As stated above, increased spasticity of quadriceps is likely to be part of synergistic activation for body support and posture stabilization. Some fold. To summarize, the major contribution of this research is the neuromuscular analysis in stroke individuals during assisted gait by robotic walker and the main feature found was a longer stance phase in the walker-assisted gait compared to the free gait. Even due to the heterogeneity of stroke individuals, there are some common general characteristics in gait, such as premature onset, and prolonged duration of firing and peaks of activity that differ from normal gait (Balaban and Tok, 2014). The development of robotic devices for rehabilitation should consider patient’s residual abilities, activities they have to develop in their daily tasks and work, the device comfort and practical aspects (Helal et al., 2008). Consequently, adults with hemiparesis frequently require walking aids, such as a singlepoint cane, crutch, 4point cane, hemiwalker or rollator. Brain 130, 159–169. Trunk lateral flexion and pelvic elevation were much improved at 6 weeks after injection. (2017). Using this fundamental approach, the muscle activities are not controlled individually. The influence of locomotor rehabilitation on module quality and post-stroke hemiparetic walking performance. Pathophysiology of spasticity. Furthermore, the authors reported that the number of simplified modules was correlated to preferred walking speed, speed modulation, step length asymmetry, and propulsive asymmetry. doi: 10.1016/j.jbiomech.2009.10.009, Miller, D. M., Klein, C. S., Suresh, N. L., and Rymer, W. Z. Neurophysiol. In the opposite case, i.e., if the user is closer than the set-point, the walker moves away to make him/her catch the set-point. In contrast, the mortality rate ranges from 8 to 12% for the ischemic type, while the hemorrhagic type has more fatal outcomes with numbers varying between 33% and 45% (Ovbiagele and Nguyen-Huynh, 2011). Loading and knee flexion after stroke: Less does not equal more. J. Physiol. Stretch reflex coupling between the hip and knee: implications for impaired gait following stroke. In the mid stance, there is excessive hip and knee flexion, ankle dorsiflexion, and trunk forward leaning. PMid:20703612. http://dx.doi.org/10.1007/s10916-009-9311-8. Stroke survivors usually have decreased stance phase and prolonged swing phase of the paretic side. Gait disorders in the elderly are common and in most cases cannot be treated medically or surgically. Phys. [ Links ], Cifuentes CA, Rodriguez C, Frizera-Neto A, Bastos-Filho TF, Carelli R. Multimodal human-robot interaction for walker-assisted gait. A lesion that occurs in the anterior cerebral artery, for example, may cause motor injuries predominantly in the lower extremity of the contralateral side, which interfere in the gait and body balance (Pare and Kahn, 2012). doi: 10.1056/NEJMcp043511, Drew, T., Kalaska, J., and Krouchev, N. (2008). 9:1021. doi: 10.3389/fphys.2018.01021. Therefore, a sound knowledge of the normal gait pattern and cadence is of utmost importance in evaluating and understanding the limitations of the patient with abnormal gait patterns and in prescribing the appropriate ambulatory assistive device. GF and PZ critically revised the manuscript and contributed substantially to the manuscript development. doi: 10.1016/0966-6362(96)01063-6, Owen, E. (2010). Gait Posture 18, 114–125. She received botulinum toxin injections several times in the first 3 years after the accident. All authors read and approved the final manuscript. Hemiparetic gait following stroke. Once collected to the computer, the signals were analyzed to identify the gait phases and muscle activity. (2008). The Co-ordination and Regulation of Movements. New Jersey: John Wiley & Sons; 2008. The kind of electrodes used was Ag/AgCl discoid shape, with 10 mm diameter, pre-gelled and with inter-electrode distance of 20 mm. 2005; 63(3B):847-51. Compensatory movements and lower limb asymmetry cause changes in the gait patterns of stroke patients (Beaman et al., 2010), and the spasticity increases the oxygen demand (Lee et al., 2010; Roger et al., 2011). 45, 335–355. Both sEMG and accelerometer data were recorded simultaneously using an acquisition equipment EMG 830C (EMG System do Brasil Ltda®) with 16-bit analog/digital conversion resolution, amplifier gain up to 2000V/V, common mode rejection > 100dB, input impedance of 109Ω, and maximum sampling frequency of 2 kHz. Gard, S. A., and Childress, D. S. (1997). 2 point gait pattern: Definition. The purpose was to understand human gait in general and to explain gait abnormality after orthopedic disorders in particular, such as hip joint fusion. Curr. These recent advances in understanding the pathophysiology of spasticity and its relations to muscle weakness can help us better understand hemiplegic gait in stroke survivors. Based on decades of animal studies and recent human research (Brown, 1994; Gracies, 2005; Nielsen et al., 2007; Mukherjee and Chakravarty, 2010; Burke et al., 2013; Stecco et al., 2014; Li and Francisco, 2015), there are advances in understanding the pathophysiology of spasticity and its relation with paresis (Li and Francisco, 2015; Li, 2017). Upper extremity motor impairments and microstructural changes in bulbospinal pathways in chronic hemiparetic stroke. In addition, the results of this study regarding muscle activation during assisted gait showed statistically significant differences in VM and BF offset, and VM onset, when compared to the free walking. Primarily due to muscle strength on the paretic side, there is a hierarchy of gait impairments.
