The assessment of your neuromuscular control reveals the health of your nerves, muscles, ligaments and joint surfaces and how well these joint components coordinate to produce well-trained, stable, healthy movement. When your joints are weak, stiff, clumsy and uncoordinated, this is because one of more of your joint components are unhealthy.
Your neuromuscular control depends upon quality signaling from your central nervous system which is transmitted along your motor nerves to regulate the onset, maintenance and offset of your muscle contractions. That signal quality is determined by incoming feedback from your joints to your brain through your sensory nerves. This feedback includes information about where your limbs are in space, the alignment of the bones within your joints, the pressure within your joint capsules and how much stretch is placed upon your ligaments, tendons and muscles.
It is the condition of this mechanical feedback which determines the quality of your neuromuscular control. Incoming feedback from your normally aligned, healthy joints keys your central nervous system to full neuromuscular control. Abnormal mechanical feedback from misaligned, injured or diseased joints keys your central nervous system to attenuate or deactivate signaling communicated to your muscles through your motor neurons, thereby inhibiting control of your muscles. When neuromuscular control is lost, spinal and extremity joint weakness, stiffness and instability are the consequence.
In this example, by correcting the patient’s lumbar (low back) subluxations (miss-alignments), normal nerve feedback from these vertebral joints informs the brain to restore lumbar nerve root signaling responsible for controlling her hip and leg muscle strength and proprioception.
