We assessed performance fatigability and recovery in people with PD compared to healthy-aging controls. Fifteen females with PD and 14 healthy-aging controls underwent neuromuscular testing of knee extensors using dynamometry. Participants then performed repeated maximal-effort isotonic knee extensions at a 20 % maximum voluntary contraction (MVC) load until peak power declined 40 %. Performance fatigability was assessed by repetitions to task failure, with recovery tracked for 10 min afterwards. Despite no baseline differences in neuromuscular performance, PD achieved ∼58 % fewer repetitions to failure. Immediately post-task failure, compared to controls, PD exhibited less fatigue-induced impairments in MVC torque, voluntary activation, and quadriceps electromyographic (EMG) activity, but similar impairment of twitch torque. For power and twitch torque, PD and controls recovered similarly, whereas PD recovered sooner for MVC torque and quadriceps EMG. Isotonic performance fatigability differs subtly between PD and healthy controls, providing novel insights into the physical manifestations of fatigue in PD and potential implications for understanding disease progression and management.</div></div>","PeriodicalId":56123,"journal":{"name":"Journal of Electromyography and Kinesiology","volume":"83 ","pages":"Article 103023"},"PeriodicalIF":2.0,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144189972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In view of new technical possibilities to measure the neuromuscular system via contactless magnetomyography (MMG) using miniaturized quantum sensors (optically pumped magnetometer, OPM), the question arises whether MMG detects similar neuromuscular adaptations compared to EMG. Therefore, we developed an experimental design and a multimodal setup for the simultaneous measurement of EMG, triaxial OPM-MMG, and vigorimetry. As a proof of concept, right biceps brachii muscle activity was recorded during maximal voluntary contraction (MVC) and a 40 % MVC muscle fatigue paradigm over 3 min in 12 healthy, untrained subjects. Measurements were taken before and after a 30-day strength training program, with six subjects undergoing training and six serving as controls. EMG and MMG showed a similar increase in RMS during MVC and fatigue after training (r > 0.9). However, the MMG increase varied by vector component, with the magnetic flux signal along the muscle fibers showing the highest RMS increase. Furthermore, these MMG findings can be visualized three-dimensionally using one OPM, which is not possible with bipolar EMG. This is the first longitudinal MMG study to demonstrate the feasibility of monitoring strength training-induced adaptations over 4 weeks, which highlights the opportunities and challenges of OPM-MMG for contactless neuromuscular monitoring.</div></div>","PeriodicalId":56123,"journal":{"name":"Journal of Electromyography and Kinesiology","volume":"82 ","pages":"Article 103012"},"PeriodicalIF":2.0,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143923622","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The MVMD technique is utilized to decompose and fuse sEMG signals, enriching signal content and improving feature representation. To further optimize gesture classification performance, the convolutional block attention module (CBAM) and CrissCross attention mechanism are integrated into the neural network, enabling superior learning of local and spatial features. The experimental results show that the MVMD-TCCA method achieves an average classification accuracy of 85.09 % on the NinaPro DB2 dataset, representing a 13.46 % improvement compared to the use of the original signal, and an average classification accuracy of 97.90 % on the dataset collected from 15 subjects, reflecting a 1.70 % improvement over the original signal.
