Muscle Synergies in Running: A Review

Published:Dec 31, 2025 06:01
1 min read
ArXiv

Analysis

This review paper provides a comprehensive overview of muscle synergy analysis in running, a crucial area for understanding neuromuscular control and lower-limb coordination. It highlights the importance of this approach, summarizes key findings across different conditions (development, fatigue, pathology), and identifies methodological limitations and future research directions. The paper's value lies in synthesizing existing knowledge and pointing towards improvements in methodology and application.
Reference

The number and basic structure of lower-limb synergies during running are relatively stable, whereas spatial muscle weightings and motor primitives are highly plastic and sensitive to task demands, fatigue, and pathology.

Analysis

This paper addresses the limitations of traditional methods (like proportional odds models) for analyzing ordinal outcomes in randomized controlled trials (RCTs). It proposes more transparent and interpretable summary measures (weighted geometric mean odds ratios, relative risks, and weighted mean risk differences) and develops efficient Bayesian estimators to calculate them. The use of Bayesian methods allows for covariate adjustment and marginalization, improving the accuracy and robustness of the analysis, especially when the proportional odds assumption is violated. The paper's focus on transparency and interpretability is crucial for clinical trials where understanding the impact of treatments is paramount.
Reference

The paper proposes 'weighted geometric mean' odds ratios and relative risks, and 'weighted mean' risk differences as transparent summary measures for ordinal outcomes.

Analysis

This paper addresses the critical challenge of reliable communication for UAVs in the rapidly growing low-altitude economy. It moves beyond static weighting in multi-modal beam prediction, which is a significant advancement.

Analysis

This paper addresses the instability of soft Fitted Q-Iteration (FQI) in offline reinforcement learning, particularly when using function approximation and facing distribution shift. It identifies a geometric mismatch in the soft Bellman operator as a key issue. The core contribution is the introduction of stationary-reweighted soft FQI, which uses the stationary distribution of the current policy to reweight regression updates. This approach is shown to improve convergence properties, offering local linear convergence guarantees under function approximation and suggesting potential for global convergence through a temperature annealing strategy.
Reference

The paper introduces stationary-reweighted soft FQI, which reweights each regression update using the stationary distribution of the current policy. It proves local linear convergence under function approximation with geometrically damped weight-estimation errors.

Analysis

This paper addresses a key limitation of Fitted Q-Evaluation (FQE), a core technique in off-policy reinforcement learning. FQE typically requires Bellman completeness, a difficult condition to satisfy. The authors identify a norm mismatch as the root cause and propose a simple reweighting strategy using the stationary density ratio. This allows for strong evaluation guarantees without the restrictive Bellman completeness assumption, improving the robustness and practicality of FQE.
Reference

The authors propose a simple fix: reweight each regression step using an estimate of the stationary density ratio, thereby aligning FQE with the norm in which the Bellman operator contracts.

Analysis
