A within-subject biomechanical comparison of stepping and non-stepping responses to identical unexpected perturbations (under review)
- Compares stepping and non-stepping responses within the same participants.
- Uses identical unexpected perturbations to distinguish response strategy from perturbation conditions.
- Examines the biomechanical differences between the two response types.

Effects of Biomechanical Improvements in Manual Handling Equipment on Users’ Muscle Activations
- Compares trunk and lower-limb muscle activation in 28 healthy adults who performed pushing, pulling, and lifting tasks with a 20-kg load.
- Finds that the long adjustable handle reduced T7 erector spinae activation across all tasks and soleus activation during pulling compared with the short handle.
- Indicates that an extended adjustable handle may reduce muscular and musculoskeletal demands during industrial manual handling.

Muscle Synergy Analysis for Identifying Muscle Coordination Patterns: A Non-negative Matrix Factorization (NMF)-Based Case Study
- Presents a practical framework that uses non-negative matrix factorization to decompose EMG signals into muscle synergies and variance accounted for to select the number of synergies.
- Demonstrates the framework with simulated two-channel EMG data under a single-synergy assumption.
- Uses five proportional, inverse, and independent signal patterns to illustrate muscle coordination in sports and clinical settings.
