Summary

Story summary

Researchers found a sub-kilogram knee robot improved function in six children with spinal muscular atrophy.
The robot provides isokinetic resistance that rises with leg speed and falls when speed drops.
After 30 sessions over six weeks, the children’s standing-from-sitting angle improved from 111° to 104°.
Knee torque more than doubled after the training period.
Parents reported that daily tasks such as rolling out of bed became easier.
