Routine clinical motion analysis: comparison of a bespoke real-time protocol to current clinical methods

Abstract

Motion analysis (MA) hardware has recently become more accessible; however, protocols have not developed in conjunction. Routine clinical assessment mostly relies on unreliable observational methods. This study aimed to develop an MA protocol for routine clinical use and compare kinematics and reliability to the gold-standard. Ten participants completed 10 over ground walks with a comprehensive marker set (bespoke and gold-standard). Inter/intra-assessor reliability was also compared. Results demonstrated comparable kinematics. Reliability of the bespoke model was lower than the gold standard but higher than observational methods. The bespoke model can be recommended for routine clinical use to assess patient progress and function.

A strathclyde cluster model for gait kinematic measurement using functional methods: a study of inter-assessor reliability analysis with comparison to anatomical models

“…These markers cannot be removed using functional methods. Studies have proposed a technical cluster set attached to the sacrum where the pelvis ALs can be transferred as markers in the technical coordinate system using a calibration wand (Borhani et al 2013;Millar et al 2019). Borhani et al (2013) showed that the use of the cluster set had a higher repeatability in non-sagittal hip angles compared to the regression models, especially for the group of obese participants (BMI > 28).…”

A pilot randomised control trial of the efficacy of stability-based training with visualisation for people with chronic ankle instability

“…Body segments were determined using pointer calibration at 16 pre-determined anatomical landmarks and segment clusters (Strathclyde Cluster Model) which allowed for an avatar to be generated that showed the participants' pose in real time (Fig. 1) [29,30]. Joint coordinate systems and kinematics for this model were calculated as per International Society of Biomechanics recommendations [31,32].…”

A Practical Gait Feedback Method Based on Wearable Inertial Sensors for a Drop Foot Assistance Device

“…Each participant wore Trigno TM IM sensors (Delsys Inc., USA) attached to the shank and foot of both legs. To validate our real-time gait measurement system, the participant also wore a marker set of Strathclyde functional cluster model [35], Fig 4. A 12 camera Vicon motion capture system (Vicon MX Giganet, Oxford Metrics Ltd., UK) was used as the reference.…”
