It is important to ensure the client can return to upright after activating the dynamic component. If not, the component resistance can be changed. If this is not adequate to return the client to upright, dynamic options may not be appropriate.
It is also important to ensure the client return to an appropriate posture. For example, a client may return to upright after extending at the hips, but assume a posterior pelvic tilt. Individual manufacturer’s dynamic components work differently and may vary in ability to return the client to an optimal posture.
Some clients may experience increased extensor tone and/or postural insecurity and anxiety in response to dynamic movement. Decreasing the amount of movement may help.
