Ageing and Proprioception

Ageing and Proprioception in the asymptomatic shoulder: an observational cohort with reliability assessment

Project group 



Laboratory site

Laboratory for Kinematics & Neuromechanics (LK&N) at the LUMC.

Start date  

March 1st, 2018



An age-related decline in proprioception may be the trigger for developing shoulder complaints such as the Subacromial Pain Syndrome (SAPS). In order to study proprioception in SAPS, we developed a non-invasive measuring protocol in cooperation with the Technical University Delft (faculty Clinical Technology). 


In preparation of future studies assessing proprioception in shoulder pathology such as SAPS, we will 1) test the hypothesis that there is an age-associated decline in proprioception in asymptomatic participants, 2) assess the reproducibility and repeatability of the newly developed measuring protocol. 

Study design

Observational cohort with assessment of proprioception in 40 to 120 asymptomatic participants. There are two study-related visits, one week after another, with two assessments per visit. 

Study population

Forty asymptomatic participants between the age of 18 through 70, without any (current or past) shoulder complaints and no interest in the findings of this research. 


No study related interventions. 

Main study parameters/endpoints

For the assessment of proprioception we will test Joint Position Reproduction (JPR) in a 3-Dimensional motion tracking device (Flock of Birds). Participants will also rate the subjective JPR acuity during all measurements. The Constant score will be obtained once and demographic characteristics will be noted.
