We are studying how the human cortex processes proprioceptive afference from the knee joint. Join our Proknee study!
We are launching a study to investigate cortical processing of proprioceptive afference from the knee joint. The study aims to quantify whether the steady volitional activation of the knee extensors affects the naturalistic proprioceptive afference arising from the knee joint using patellar tendon tap. We are looking for female and male participants aged 18-45.

We aim to investigate whether the steady volitional activation of the quadriceps muscles modulates the cortical proprioceptive processing of the knee joint by using magnetoencephalography (MEG). And the patellar tendon reflex as the real-world-naturalistic stimulation condition, is used as the proprioceptive stimulation trigger.
What we test:
- Magnetoencephalographic (MEG)/electromyographic (EMG) signal recording;
- The hammer tapping stimulation on the patellar tendon during active and passive conditions;
- The total duration is around 2 hours.
Eligibility criteria:
- Male and female participants aged 18–45;
- No any injuries in the lower limbs at recent 6 months;
- No neurological diseases, and no family history of such conditions;
- No metallic implants in the body.
Where we test:
University of Jyväskylä, MEG laboratory, in Kärki building in Mattilanniemi 6.
