Instead of using the feet, a tensile force can be controlled by use of the hands if both the kinematic configuration and orientation of the body are facilitated. The foot remains stationary on the ground supporting the contralateral side of the body for a dwell time, allowing the other foot to swing forward. Thus, when a heel strikes the ground, muscles must react synergically, using reflexes to maintain the body’s centre of mass inside the boundaries of the base of support. Fine equilibrium control is an elemental motor-behavior occurring especially when only one foot supports the entire body. Normally, forward walking does not require conscious control of equilibrium. Considering only the end of the stride cycle, the actor is confident that the heel will strike the ground for the upcoming stance phase. In natural coordination mode, such as walking at comfortable speed, the feet alternate between three phases: swing, heel strike and stance phases.
New & Noteworthy: There is evidence that elastic tubing can be used to simulate the vertical component of the ground reaction force. It also permits pelvic movement: a dynamic swaying of maximum amplitude to both sides, while hands and feet are held stationary (cf. In this example, the top-to-bottom arrangement of elastic tubes applies a tensile force which stabilizes the pelvis. One way to augment impedance is by using elastic tubes, its tensile force acting to pull the pelvis towards the feet (the base of support), which facilitates recalibration of the neuromuscular system. Treatment of motor disabilities, based on a learning process, demonstrates efficiency when the lower limbs’ impedance is augmented (Diederichs, 2018). Neuromodulation impacting muscle tone with long-lasting amelioration of motor Additionally, the treatment is highlighted as a Initiates a transition from the dynamics of the action system and taskĬonstraints to a default value. Treatment is able to trigger a mechanism that detects a critical value and Groups 2 and 3, the improvement in thoracic symmetry was significant.
Variables were measured: four ranges of motion, two perceived effort s, and one pain. With the dominant or the non-dominant hand, respectively, for comparison.

Indeterminacy of limb lengths, the regulation of joint rotation and theĬombination of multiple joints for performing the motor task. This reduces the burden on the CNS to deal with the The hand first reaches the target position constraining the overall degrees ofįreedom to just one. This pairing of CS with US generates a sequence of events, the conditioned response ( CR).
