Most leg pain is transferred pain from our backs or hips. [1] Foot injuries including plantar fasciitis is another source of pain which is associated with-standing for long periods. [ 1 ] [ 6 ] There are three major tendons that maintain stability at the ankle joint; anterior extensors , medial flexors and lateral peroneal , these tendons ...
Striking of the patellar tendon with a reflex hammer just below the patella stretches the muscle spindle in the quadriceps muscle. [2] [3] This produces a signal which travels back to the spinal cord and synapses (without interneurons) at the level of L3 or L4 in the spinal cord, completely independent of higher centres. [4]
The stretch reflex is accomplished through several different structures. In the muscle, there are muscle spindles, whose intrafusal muscle fibers lie parallel to the muscle and sense changes in length and velocity. The afferent sensory neuron is the structure that carries the signal from the muscle to the spinal cord.
Posture can even make a difference when it comes to chronic pain, from headaches to neck, shoulder, and back stiffness and aches, maintaining proper alignment can help you move and feel better ...
Postural control refers to the maintenance of body posture in space. The central nervous system interprets sensory input to produce motor output that maintains upright posture. [ 1 ] Sensory information used for postural control largely comes from visual , proprioceptive , and vestibular systems. [ 2 ]

In physiology, medicine, and anatomy, muscle tone (residual muscle tension or tonus) is the continuous and passive partial contraction of the muscles, or the muscle's resistance to passive stretch during resting state. [1] [2] It helps to maintain posture and declines during REM sleep. [3]
A stretch reflex occurs when a muscle is stretched and then contracts protectively while opposing muscle groups relax. An example of this during gait occurs when the weight-bearing leg nears the end of the stance phase. At this point the hip extends and the hip flexors are elongated.
