Bio Mechanical Assessments




noun: bio-mechanics

1. the study of the mechanical laws relating to the movement or structure of living organisms.


Trinitas Group is proud to be the only provider of the patent pending utilisation of bio-mechanics in the personal injury sector.

Our two unique reports include

  • Bio mechanical assessments of surveillance footage: and
  • Mechanism of Injury reports


Bio mechanical assessments (BMA) of surveillance footage

Utilising both qualitative and quantitative assessments our reports “medicalise” surveillance footage providing you with a clearer understanding of surveillance footage findings.


Qualitative observational analysis

In our reports surveillance footage is used to determine the presence or absence of indicators of injury (listed below) during functional movements. Qualitative observational analysis is conducted to determine the following:

  • Reduced strength and/or Range of Motion (ROM)
  • Activity avoidance and/or modification
  • Apprehension
  • Guarding
  • Grimacing/Wincing
  • Bracing Rubbing
  • Restlessness


Quantitative motion analysis

In our BMA reports Quantitative motion analysis is conducted to determine functional range of motion for the joints of interest captured in surveillance footage. Coordinate data as per the below body markers allow for key movements to be analysed using motion analysis software

Find below an example extract from our reports that clearly indicates the claimants claimed vs assessed vs normal range of motion.

Our medicalised surveillance reports are an essential tool for all Soundly Based Liability decisions and Whole Person Impairment (WPI) assessments




Mechanism of Injury Report

Utilising the basic principles of biomechanics which include

  • Force
  • Linked segments
  • Impulse-causing momentum
  • The stretch-shorten cycle
  • Summing joint forces
  • Continuity of joint forces
  • Impulse direction
  • Rotational motion
  • Moment of inertia
  • Stress causing strain


Our MI Reports  

  • Calculate likelihood of the possibility of an alleged injury
  • Review medical literature available on the injury
  • Provide opinion on liability
