Evaluating the Reliability of Markerless Gait Analysis: Insights from Theia3D
A recent study published in PeerJ assessed the reliability of Theia3D’s markerless motion capture system under varying clothing conditions during walking. The findings indicate that both tight and loose-fitting clothing yield consistent gait analysis results, with minimal variation observed between trials and sessions.

Summary

A recent study published in the Journal of Orthopaedic & Sports Physical Therapy (JOSPT) investigates the relationship between early sports specialization and hip kinematics in ice hockey goaltenders. Using Theia3D markerless motion capture technology, researchers examined how hip movements differ between early specialized (ES) and non-early specialized (NES) goaltenders. The findings suggest that ES goaltenders demonstrate distinct hip movement patterns, potentially as a strategy to mitigate injury risk. This research provides important insights into training practices, injury prevention, and sport specialization guidelines for young athletes.

Research Overview 

‍Study Aim: To compare hip kinematics between ES and NES ice hockey goaltenders.

‍Methods: 26 goaltenders (13 ES, 13 NES) aged 16-25, who actively played at least once per week. Theia3D markerless motion capture system recorded hip kinematics during three goaltending movements on a slide board. Maximum and minimum hip flexion, adduction, and internal rotation angles were measured.

‍

Key Findings:

  • Altered Hip Kinematics: ES goaltenders exhibited greater hip internal rotation and abduction at lower flexion angles but had reduced internal rotation and abduction at higher flexion angles compared to NES goaltenders.‍
  • Avoidance or Adaptation? ES goaltenders may have developed improved movement strategies to avoid or reduce pain associated with untreated or developing femoroacetabular impingement syndrome (FAIS) or labral tears, or may be demonstrating greater hip joint control to avoid hip mechanics which could lead to hip injuries in ice hockey goaltenders.‍
  • No Extreme Hip Ranges Reached: Neither group consistently reached the extreme ranges of motion typically associated with mechanical bony impingement, suggesting other factors contribute to hip injuries. ‍
  • Potential Impact on Self-Reported Hip Function: Greater hip internal rotation at maximum flexion and increased hip abduction during certain slides were associated with poorer self-reported athletic hip function.

‍

Implications for Ice Hockey Training

Early specialization in ice hockey goaltending leads to the use of altered hip kinematics during common goaltending movements relative to non-early specialized goaltenders, however no causal relationship was established between early specialization, these kinematic differences, and hip injuries. Coaches and trainers should consider incorporating diverse training regimens that promote overall athletic development and avoid overloading specific structures, potentially mitigating the risks associated with specialized movement patterns.

The Role of Markerless Motion Capture in Sports Research

Advancements in markerless motion capture technology, such as Theia3D, have enhanced the ability to analyze complex movements in sports. These systems offer: 

  • Increased Efficiency: Streamlined data collection processes without the need for markers.
  • Improved Participant Engagement: Allowing athletes to perform naturally in their own apparel and equipment.
  • Reduced Inter-Rater Variation: Automated data analysis minimizes human errors associated with marker placement.‍
  • Increased Ecological Validity: Participants can be tested in more natural environments.

These technologies can be instrumental in assessing the impact of training practices on movement patterns and injury risks. Learn more about how markerless motion capture is transforming biomechanics research.

Future Research Directions

Further research is needed to:

  • Assess Long-Term Impacts: Evaluate how early specialization affects hip health over an athlete’s career.‍
  • Explore Preventative Measures: Identify training interventions that can mitigate the risks associated with early specialization.‍
  • Utilize Advanced Motion Capture: Employ markerless motion capture systems to gain deeper insights into movement mechanics and injury prevention strategies.
