Special Issue Information

Dear Colleagues,

Over the last few years, miniature and wearable human body sensors have attracted increasing attention due to their appealing applications. Wearable devices allow for a wireless, low-power-consumption, and real-time quantification of motor functions and abilities, pathological conditions, compensatory motor strategies, and improvements following pharmacological or non-pharmacological (e.g., rehabilitation) treatments and ergonomic interventions. The ongoing joint use of specific algorithms and sensors leads to an intelligent, accurate, and precise characterization of human motion.

Machine learning provides systems with the ability to automatically learn and improve from data and experience without human intervention or assistance, without being explicitly programmed to act as or better than humans. Machine learning is driven by the computational challenges of building statistical models from massive data sets and is located at the intersection of statistics, trying to find relationships based on data and computer science and create efficient computing algorithms.

Many branches of medicine, as well as robotics, ergonomics, and sports, can benefit from the use of machine learning approaches and sensors.

This Special Issue aims to collect the best scientific contributions capable of determining significant improvements on the above-described topic.

Potential topics include but are not limited to the following:

  • Human movement analysis and machine learning categorization;
  • Machine learning-based diagnostic algorithms of human movement disorders;
  • Machine learning- and movement analysis-based clinical decision in human movement disorders;
  • Machine learning for biomechanical risk classification in manual handling activities in the workplace;
  • Wearable wireless devices for movement analysis and machine learning procedures;
  • Computational models in machine learning and sensors for movement analysis;
  • Wearable wireless and machine learning communication systems in human movement biomechanics.

The purpose of the present study was to validate a new linear encoder by comparing the mean velocity (MV) and peak velocity (PV) of two linear position transducers during free-weight back squat (SQ) and bench press (BP) exercises. Barbell velocity was simultaneously recorded using GymAware (version 5.1.0; reference standard) and Velocity Matters. Fifteen male participants completed two testing sessions, each involving six repetitions (two sets of three) across five velocity ranges: >1.00 to 0.51 m·s−1 (velocity range 1: >1.00 m·s−1; velocity range 2: 0.87–0.99 m·s−1; velocity range 3: 0.75–0.86 m·s−1; velocity range 4: 0.63–0.74 m·s−1; velocity range 5: 0.51–0.62 m·s−1) in SQ and >1.02 to 0.40 m·s−1 (velocity range 1: >1.02 m·s−1; velocity range 2: 0.86–1.01 m·s−1; velocity range 3: 0.70–0.85 m·s−1; velocity range 4: 0.56–0.69 m·s−1; velocity range 5: 0.40–0.55 m·s−1) in BP. In total, 180 repetitions per velocity range were analyzed for each exercise. Validity was assessed using Pearson’s correlation (r), mean absolute error (MAE), Bland–Altman plots, the intraclass correlation coefficient (ICC), and the concordance correlation coefficient (CCC). Pearson’s r indicated good (0.5–0.7) to excellent (>0.9) correlations across all ranges and exercises. However, acceptable MAE values were found only for MV in SQ (except at >1.00 m·s−1) and for both MV and PV in BP at velocities <0.70 m·s−1. Despite an acceptable MAE in some cases, Bland–Altman analyses revealed systematic underestimation by Velocity Matters, with wide limits of agreement of up to −0.08 m·s−1 in SQ and −0.09 m·s−1 in BP, even where MAE was acceptable. ICC values were generally >0.70 but showed wide confidence intervals, indicating high uncertainty. CCC values were consistently poor (<0.90) across all velocity ranges and both exercises, except for PV in the lowest velocity range during BP. In conclusion, Velocity Matters may be cautiously used to monitor MV during SQ at velocities <0.87 m·s−1, but it does not provide sufficient accuracy for use in BP across any load. Full article
