PMID 41948192WHAT IT FOUND
In one patient with severe post-stroke arm weakness, a three-phase program using gravity support, electrical stimulation, and orthoses to progressively release joint constraints was associated with reduced spasticity, less pain, and slight motor improvement.
This is a single case, not evidence of efficacy.
Key findings
01The patient received intensive rehabilitation including physical therapy, occupational therapy, and speech-language therapy before the specific upper limb program began.
02The upper limb program used four assistive devices concurrently: an arm support, neuromuscular electrical stimulation, a static wrist-hand-finger orthosis, and a dynamic finger extension orthosis.
03Total Fugl-Meyer Assessment motor scores improved from 12 at baseline to 17 at discharge, with spasticity reductions in multiple muscle groups.

What it does not show
This is a single case report without a control group, so it cannot establish causality. Multiple concurrent treatments (PT, OT, SLP, specific devices) were used, making it impossible to isolate the effect of the degrees-of-freedom constraint strategy alone. The intervention started in the late subacute stage, so spontaneous recovery cannot be ruled out as a contributor to the observed improvements. No objective electrophysiological measures (like EMG) were used to confirm changes in muscle activation. Long-term outcomes beyond discharge were not assessed.

The easy way to misread this
Do not conclude that the degrees-of-freedom constraint strategy caused the improvement. The patient received multiple concurrent therapies (PT, OT, SLP) and devices, and the program started in the late subacute phase where spontaneous recovery is still possible. This single case describes what happened to one person, not a proven treatment effect.
