Proprioception doesn’t have to be restricted to the individual, nor are ideas of senses outside the classical five restricted to the modern day (The power of proprioception: how to improve your ‘sixth sense’ – and become healthier and happier, 18 July). I’m a medieval historian of education and physical training, and there are discussions of using proprioception in wrestling and longsword combat manuals from the 15th century.
The idea is to sense the opponent’s strength and intentions through physical contact. Those who want to develop their proprioception should consider martial arts that involve grappling or fencing, including historical European martial arts (Hema). It’s great fun and there are more clubs than you might think.

Proprioception is something that the Chinese have known for 2,000 years and anyone interested in the skills set out in the tests doesn’t need to jump from rooftops (AKA parkour); they just need to find a tai chi class. I am 70 and can easily do all these exercises, but then I’ve practised tai chi for 20 years. There is evidence of the benefits to health and mobility through tai chi.

I’m in my 60s but did the “rock pass” drill in the article with ease. My proprioception has no doubt been aided by years of moving with many partners to the accompaniment of Afro-Cuban music. There are clubs for it, and it’s the most fun you can have with your clothes on.
