Testing whether sensorimotor gains transfer beyond practiced movements.
In this hypothetical example, improvement with the trunk limited supports better performance under that restriction, provided baseline used the same restriction. I'd compare that gain with a group repeating the restricted assessment without the reaching practice. A larger gain after practice would support transfer to restricted reaching alongside the changed unrestricted strategy, while leaving broader arm capacity unresolved.
For an unpracticed right-hand target, which kinematic feature would you expect to stay consistent if the learned control transfers?
Suppose practice improves adaptation during right-hand reaching. Would left-hand reaching to matched targets be a convincing transfer test, or does changing the effector also change too much of the task? I’d separate immediate performance on that untrained movement from retention after a delay, since rapid acquisition and durable transfer are different claims.
