Knee kinematics before and 6 and 18 weeks after BtA injection

Kinematics	Before injections		6 weeks after injections		18 weeks after injections
	Maximum angle	SD	Maximum angle	SD	Maximum angle	SD
Ankle dorsiflexion in stance phase	−3.0°	14.3°	6.2°*	14.2°	4.5°	10.4°
Ankle dorsiflexion during gait cycle	−1.9°	13.7°	7.2°*	10.7°	4.8°	9.8°
Knee recurvatum during midstance	−12.4°	9.4°	−10.2°	11.4°	−6.2°	6.0°

BtA = botulinum toxin; * significant difference (p < 0.05 in t-test) compared with the values before injection.
