In response to the problem that the traditional lower limb rehabilitation scale assessment method is time-consuming and difficult to use in exoskeleton rehabilitation training, this paper proposes a quantitative assessment method for lower limb walking ability based on lower limb exoskeleton robot training with multimodal synergistic information fusion. The method significantly improves the efficiency and reliability of the rehabilitation assessment process by introducing quantitative synergistic indicators fusing electrophysiological and kinematic level information. First, electromyographic and kinematic data of the lower extremity were collected from subjects trained to walk wearing an exoskeleton. Then, based on muscle synergy theory, a synergistic quantification algorithm was used to construct synergistic index features of electromyography and kinematics. Finally, the electrophysiological and kinematic level information was fused to build a modal feature fusion model and output the lower limb motor function score. The experimental results showed that the correlation coefficients of the constructed synergistic features of electromyography and kinematics with the clinical scale were 0.799 and 0.825, respectively. The results of the fused synergistic features in the K-nearest neighbor (KNN) model yielded higher correlation coefficients (r = 0.921, P < 0.01). This method can modify the rehabilitation training mode of the exoskeleton robot according to the assessment results, which provides a basis for the synchronized assessment-training mode of “human in the loop” and provides a potential method for remote rehabilitation training and assessment of the lower extremity.
Knee osteoarthritis (KOA) is the most common degenerative joint disease and one of the most disabling diseases in China, causing a huge economic burden to patients, families and society. Standardized KOA rehabilitation treatment is an important means to prevent and treat the disease and promote the development of high-quality medical services. This guideline was updated based on the 2016 and 2019 editions, and was initiated by the Chinese Medical Association Physical Medicine and Rehabilitation Branch and West China Hospital of Sichuan University. The guideline development was guided by domestic and international guideline development methods and principles, and 11 core clinical issues in two categories (rehabilitation assessment and treatment) were selected through clinical issue screening and deconstruction, and multiple rounds of Delphi questionnaire consultation. The International Classification of Functioning, Disability and Health (ICF) was used as the theoretical framework, and the Grading of Recommendations Assessment, Development and Evaluation (GR) was used based on the best available evidence. The International Classification of Functioning, Disability and Health (ICF) is a theoretical framework based on the best available evidence, and uses the Grading of Recommendations Assessment, Development and Evaluation (GRADE) method to grade the quality of evidence and recommendations, and reports them according to the Reporting Items for Practice Guidelines in Healthcare (RIGHT), taking into account patients' preferences and values and the needs of Chinese clinical practice, resulting in 11 key points and 28 recommendations to systematically standardize the rehabilitation of knee osteoarthritis.
Osteoporosis (OP) is one of the most serious health problems, causing a huge economic burden to patients, families and society. OP rehabilitation treatment plays an important role in pain-relieving, reducing the risk of fracture, improving the ability of daily activities, and promoting the healing of osteoporosis fractures, and has been increasingly valued and recommended by domestic and foreign guidelines. This guideline was updated based on the Chinese expert consensus on rehabilitation intervention for primary osteoporosis 2019 editions, and was initiated by Chinese Society of Physical Medicine and Rehabilitation professor HE Chengqi, Chairman of the Chinese Medical Association Physical Medicine and Rehabilitation Branch. This guideline development was guided by domestic and international guideline development methods and principles, and selected through clinical issue screening and deconstruction, and two rounds of Delphi questionnaire consultation. The International Classification of Functioning, Disability and Health (ICF) was used as the theoretical framework, and the grading of recommendations assessment, development and evaluation (GRADE) was used based on the best available evidence. The ICF is a theoretical framework based on the best available evidence, and uses the GRADE method to grade the quality of evidence and recommendations, and reports them according to the Reporting Items for Practice Guidelines in Healthcare (RIGHT), taking into account patients’ preferences and values and the needs of Chinese clinical practice, resulting in 22 recommendations in 7 aspects of rehabilitation assessment, physical agents therapy, occupational therapy, rehabilitation brace, cognitive behavior and psychological therapy, traditional Chinese medicine therapy and health education to systematically standardize the rehabilitation of osteoporosis.
