OBJECTIVE: To evaluate the feasibility and effectiveness of a wearable robotic
device in guiding isometric torque generation and passive-active movement
training for ankle motor recovery in children with acute brain injury.
SETTING: Ten inpatient children with acute brain injury being
treated in a rehabilitation hospital. DESIGN:
Daily robot-guided ankle
passive-active movement therapy for 15 sessions, including isometric torque
generation under real-time feedback, stretch-ing, and active movement training
with motivating games using a wearable ankle rehabilitation robot. MAIN MEASURES:
Ankle biomechanical improvements induced by each training session including ankle
range of motion (ROM), muscle strength, and clinical (Fugl-Meyer Lower-Extremity
(FMLE), Pediatric Balance Scale (PBS)) and biomechanical (ankle ROM and muscle
strength) outcomes over 15 training sessions. RESULTS: As training progressed,
improvements in biomechanical performance measures followed logarithmic curves.
Each training session increased median dorsiflexion active range of motion (AROM)
2.73 degrees (standard deviation (SD) 1.14), dorsiflexion strength 0.87 Nm (SD
0.90), and plantarflexion strength 0.60 Nm (SD 1.19). After 15 training sessions
the median FMLE score had increased from 14.0 (SD 10.11) to 23.0 (SD 11.4), PBS
had increased from 33.0 (SD 19.99) to 50.0 (SD 23.13) (p < 0.05), median
dorsiflexion and plantarflexion strength had improved from 0.21 Nm (SD 4.45) to
4.0 Nm (SD 7.63) and 8.33 Nm (SD 10.18) to 18.45 Nm (SD 14.41), respectively,
median dorsiflexion AROM had improved from -10.45 degrees (SD 12.01) to 11.87
degrees (SD 20.69), and median dorsiflexion PROM increased from 20.0 degrees (SD
9.04) to 25.0 degrees (SD 8.03). CONCLUSION: Isometric torque generation with
real-time feedback, stretching and active movement training helped promote
neuroplasticity and improve motor performance in children with acute brain
injury.
