Treadmill therapy (exoskeleton assisted) for cerebral palsy

A  study using the Lokomat robotic assisted treadmill was conducted at University of Munich, Germany. The results are very exciting because they are exactly as we would have expected based on the research of BRIGHT.

The study shows that assisted gait training improves Gross Motor Skills in a very short period of time (just three weeks of periodic training).  It also shows that results improve with more intense training.

This strengthens the case of BRIGHT that a fully autonomous exoskeleton that will allow 24×7 training would be the ideal treatment approach for Children with CP.  Children that are more severely impaired would stand the most to gain because current systems like the Lokomat are bulky and require the child to exercise in a controlled environment.  This is demotivatational and impractical and therefore, only when more sophisticated exoskeleton suits which allow the child freedom to interact in a natural setting will the child be motivated to “train” intensively and thus achieve improvement through re-routing of the brain through neuroplasticity.

Robotic-assisted treadmill therapy improves walking and standing performance in children and adolescents with cerebral palsy

Abstract

Objective

Task-specific body-weight-supported treadmill therapy improves walking performance in children with central gait impairment. The aim of the study was to investigate the effect of robotic-assisted treadmill therapy on standing and walking performance in children and adolescents with cerebral palsy and to determine parameters influencing outcome.

Methods

20 Patients (mean age 11.0±5.1, 10 males and 10 females) with cerebral palsy underwent 12 sessions of robotic-assisted treadmill therapy using the driven gait orthosis Lokomat. Outcome measures were the dimensions D (standing) and E (walking) of the Gross Motor Function Measure (GMFM).

Results

Significant improvements in dimension D by 5.9% (±5.2, p=0.001) and dimension E by 5.3% (±5.6, p<0.001) of the GMFM were achieved. Improvements in the GMFM D and E were significantly greater in the mildly affected cohort (GMFCS I and II) compared to the more severely affected cohort (GMFCS III and IV). Improvement of the dimension E but not of D correlated positively with the total distance and time walked during the trial (rs=0.748, p<0.001).

Conclusions

Children and adolescents with bilateral spastic cerebral palsy showed improvements in the functional tasks of standing and walking after a 3-week trial of robotic-assisted treadmill therapy. The severity of motor impairment affects the amount of the achieved improvement.
