“…The duration of the Si-St task (1.70s) was found to be less than the St-Si task (1.83s) in the stroke patients, consistent with previous studies (8, 12, 17) , which showed that the duration of the St-Si task was always longer than the Si-St task due to more careful control of eccentric muscle groups during the St-Si tasks (31). The difference in duration may be related to differences in the type of motor control, muscle coordination and sensory inputs associated with each task (32).…”

Background Stroke patients with hemiplegia are at increased risk of falls during sit-to-stand (Si-St) and stand-to-sit (St-Si) tasks. Maintaining bilateral lower limb symmetry during those movements can reduce the incidence of falls. This study aimed to investigate bilateral lower limb symmetries during Si-St and St-Si tasks in stroke patients compared healthy controls.Methods Thirteen stroke patients with hemiplegia and thirteen healthy controls were recruited. The subjects were asked to stand up and sit down naturally from backless and armless chairs. Five Si-St and St-Si trials were collected for each subject. Kinematics and kinetics were calculated using the inverse kinematics and inverse dynamics tools of OpenSim. The Symmetry Index (SI) was used to quantify the symmetries of both sides. The 10% of SI was set as the asymmetry threshold.Results The results showed that there were significant bilateral differences (P < 0.05) in the time to reach the maximum hip and knee moment during the Si-St task in the stroke patients. All spatial-temporal characteristics in the stroke group were greater than (P < 0.05) those in the healthy group. Bilateral ankle angle showed asymmetry during the Si-St and St-Si tasks in stroke group, and the mean ankle angle SI was greater than (P < 0.05) that of the healthy group. The stroke group showed asymmetry for bilateral hip, knee, and ankle moment, vertical ground reaction force, and medial-lateral center of pressure (ML-COP) during the entire Si-St and St-Si movements, and their average SI were significantly different (P < 0.05) from those of the healthy group except the ML-COP.Conclusions Stroke patients demonstrated significant bilateral asymmetry during Si-St and St-Si tasks, which may increase the risk of falls. Targeted lower-limb strength training, especially on the affected side, may improve symmetry and reduce the risk of falls. These findings can inform the development of rehabilitation interventions for stroke patients with hemiplegia.

“…The classification accuracy can be further improved by considering a multimodal approach. Instead of only using EMG, a combination of EMG with body kinematics may improve the classification accuracy and precision [7].…”

“…Naive-Bayes model was used to classify the four different phases of STS task. The phases were determined based upon the angular deviation of the trunk and knee [7]. The four phases were: Phase I (P1) -sitting phase, where the participant sits comfortably on the stool; Phase II (P2) -intention to stand from sitting posture; Phase III (P3) -Transition phase; and Phase IV (P4) -standing phase.…”

With the increase in disability rate as well as rise in the elderly population, there is a need for a much prompt and advance methods to deliver the rehabilitation and assistive services to the patients. One important element in this context is the robotics rehabilitation devices. The therapeutic alliance is an important factor that needs to be addressed for these robotic devices where user compliance is still a broad field to be explored. Bio-signals have shown a promising approach in improving user physical and cognitive integration with these devices. Electromyogram (EMG) is one such bio-signal, originating from the peripheral nervous system, which is capable of interpreting the motion intent of the user. In the present study, the usability of EMG is shown for its feasibility in the context of rehabilitation devices. Method for acquisition, processing and classification of EMG has been discussed.

“…Nazmi et al (2019) proposed a classification approach for the segregation of stance and swing phase (HS and TO detection) from feeding EMG signal to an artificial neural network. EMG has also been used for intent, like sit to stand detection (Rasool et al, 2012;Chorin et al, 2016;Li B. et al, 2016;Roldán Jiménez et al, 2019;Bhardwaj et al, 2021) and quantitative localized muscle fatigue estimation (Boudarham et al, 2014;Ropars et al, 2016;Roldán Jiménez et al, 2019;Parent et al, 2019) during gait. Although fatigue is considered a multidimensional concept involving both physiological and psychological implications, the former dimension of fatigue can be observed in both the central and peripheral system domains (Zwarts et al, 2008) and is a widely accepted tool for fatigue estimation (Al-Mulla et al, 2011).…”

Recent Trends and Practices Toward Assessment and Rehabilitation of Neurodegenerative Disorders: Insights From Human Gait

The study of human movement and biomechanics forms an integral part of various clinical assessments and provides valuable information toward diagnosing neurodegenerative disorders where the motor symptoms predominate. Conventional gait and postural balance analysis techniques like force platforms, motion cameras, etc., are complex, expensive equipment requiring specialist operators, thereby posing a significant challenge toward translation to the clinics. The current manuscript presents an overview and relevant literature summarizing the umbrella of factors associated with neurodegenerative disorder management: from the pathogenesis and motor symptoms of commonly occurring disorders to current alternate practices toward its quantification and mitigation. This article reviews recent advances in technologies and methodologies for managing important neurodegenerative gait and balance disorders, emphasizing assessment and rehabilitation/assistance. The review predominantly focuses on the application of inertial sensors toward various facets of gait analysis, including event detection, spatiotemporal gait parameter measurement, estimation of joint kinematics, and postural balance analysis. In addition, the use of other sensing principles such as foot-force interaction measurement, electromyography techniques, electrogoniometers, force-myography, ultrasonic, piezoelectric, and microphone sensors has also been explored. The review also examined the commercially available wearable gait analysis systems. Additionally, a summary of recent progress in therapeutic approaches, viz., wearables, virtual reality (VR), and phytochemical compounds, has also been presented, explicitly targeting the neuro-motor and functional impairments associated with these disorders. Efforts toward therapeutic and functional rehabilitation through VR, wearables, and different phytochemical compounds are presented using recent examples of research across the commonly occurring neurodegenerative conditions [viz., Parkinson’s disease (PD), Alzheimer’s disease (AD), multiple sclerosis, Huntington’s disease (HD), and amyotrophic lateral sclerosis (ALS)]. Studies exploring the potential role of Phyto compounds in mitigating commonly associated neurodegenerative pathologies such as mitochondrial dysfunction, α-synuclein accumulation, imbalance of free radicals, etc., are also discussed in breadth. Parameters such as joint angles, plantar pressure, and muscle force can be measured using portable and wearable sensors like accelerometers, gyroscopes, footswitches, force sensors, etc. Kinetic foot insoles and inertial measurement tools are widely explored for studying kinematic and kinetic parameters associated with gait. With advanced correlation algorithms and extensive RCTs, such measurement techniques can be an effective clinical and home-based monitoring and rehabilitation tool for neuro-impaired gait. As evident from the present literature, although the vast majority of works reported are not clinically and extensively validated to derive a firm conclusion about the effectiveness of such techniques, wearable sensors present a promising impact toward dealing with neurodegenerative motor disorders.
