Sumary of A proprioceptive control strategy for management of low back pain:
- Modern understanding on this matter dictates that low back pain, in particular, is caused due to a postural instability resulting from poor “proprioception”, which is a term for the perception of part of our body’s own position in space..
- In fact, our trunk and lower legs are key to maintaining postural stability due to the presence of “proprioceptors”–sensory receptors responding to position and movement–in those areas..
- Elderly people suffering from low back pain tend to have poorly performing proprioceptors, which is thought to affect their “proprioceptive control strategy”–a postural control strategy in response to vibratory stimulations as proprioceptive input..
- Moreover, the studies make no distinction between poor and healthy proprioceptors and do not take into account the fact that each proprioceptor has a natural vibration response frequency..
- They then generated vibration signals using a PC and amplified and output them from the vibrators as mechanical vibratory stimulations..
- Furthermore, they allowed the frequency of stimulation to vary with time, from an initial 20 Hz (cycles/second) up to 300 Hz, to gauge the postural response as a function of the applied frequency..
