What would you think if I said you are much stronger than realize? Muscle recruitment is an interesting concept. Essentially, the nervous system (specifically, motor nerves) sends signals to a muscle to cause the muscle to contract. The only thing a muscle does is contract; everything else is a function of the nervous system. In other words, contraction of muscle for strength, power and endurance come from the muscle itself, while the speed and control of the muscle is a function of the nervous system.
This is an incredible concept and good news for rehabilitation, since recruitment of muscles and activation of muscle groups is under voluntary control. This means the brain can send signals to muscle fibers telling them to contract. This also means there is unused muscle that can instantly be used to create more functional strength and ability. With some education, training, and practice, huge functional gains can be made in a short time; biomechanics can be altered very quickly and can improve functional ability effectively. Application of this concept will unlock rehabilitation potential and utilize all the strength that is available to the body.
