The helical nature of most tai chi movements are aimed
at strengthening the limbs and core muscles of the
abdomen and back.15 This corresponds with conventional
stroke rehabilitation techniques, which also focus on
strength exercises for the limbs and the trunk. Since tai chi
is practiced while on the feet, it is also a weight-bearing
exercise that improves balance similar to conventional
rehabilitation.14 Research by Matjacic et al demonstrated
that helical movements increase stimulation of neuronal
excitability of motor neurons in stroke patients.16 The
requirement of deep breathing and relaxation of the body
and mind when practicing tai chi is consistent with stroke
rehabilitation therapies that encourage patients to relax
and stay calm to achieve a better recovery. One of the most
important principles of tai chi is “conquering the unyielding
with the yielding,” which corresponds with physiotherapy
treatment of spasticity with gentle manipulation.
