Guided Self-rehabilitation Contracts Combined With AbobotulinumtoxinA in Adults With Spastic Paresis.
Jean-Michel Gracies, Gerard E Francisco, Robert Jech and 3 others
PMID 34039905WHAT IT FOUND
Adults with chronic spastic paresis who performed guided self-stretching diaries alongside botulinum toxin injections showed significant gains in voluntary movement range and walking speed.
This open-label study cannot prove the exercises added benefit beyond the injections alone, but suggests high compliance with home programs is feasible.
Key findings
0172.1% of participants were classified as responders for the primary outcome of composite active motion at week 6 of the second treatment cycle.
02Participants improved on average by 0.12 meters per second in walking speed and 0.55 points on the Modified Frenchay Scale for arm function after two cycles.
03Adherence to the self-rehabilitation diary was high, with participants completing a mean of 92.8% of prescribed diary days.

What it does not show
The study was open-label and single-arm, meaning there was no control group receiving injections alone or exercises alone. Therefore, it is impossible to determine if the observed benefits were due to the combination of treatments or if the self-rehabilitation exercises added any value beyond the botulinum toxin. Assessments were performed by the same physicians who administered the injections, introducing potential bias. GSC monitoring was conducted via telephone rather than in-person, which differs from the standard GSC protocol and may affect generalizability. The Modified Frenchay Scale and 10-meter walk test were not validated in the specific languages used across the four countries.
Declared interests
Several authors received consulting fees, research grants, or honoraria from Ipsen (the manufacturer of abobotulinumtoxinA/Dysport), Allergan, and Merz. One author was an employee of Ipsen at the time of manuscript development.
The easy way to misread this
Do not conclude that guided self-rehabilitation contracts are superior to, or necessary for, effective botulinum toxin treatment. This was a single-arm study with no control group, so the contribution of the exercises to the observed improvements cannot be separated from the effect of the injections alone.
