Abstract
［ Purpose］ We aimed to elucidate the relationship between an ankle selective
muscle release operation for patients with diplegic cerebral palsy and selective motor control
in the lower extremities.
［Methods］ Nine patients with diplegic cerebral palsy participated in this study. To assess
the relationship between an ankle operation and selective motor control in the lower
extremities, we compared a Selective Control Assessment of the Lower Extremity（ SCALE）,
Modified Ashworth scale（ MAS）, and ankle ROM before and after the operation. We also
examined the correlation of the degree of improvement in the SCALE and MAS. The SCALE
can assess selective motor control, while MAS can assess the feeling of resistance.
［Result］ There were meaningful improvements in the SCALE, MAS, and ankle ROM.
There were meaningful correlations between the degree of improvement in the SCALE and
MAS.
［Conclusion］ The ankle operation and postoperative physical therapy improved the
SCALE, MAS, and ankle ROM. The feeling of resistance with dorsiflexion of the ankle joints
was related to improvement of selective motor control in the lower extremities.
