Which home exercises are safest for unilateral paralysis after 6 months?
The evidence retrieved does not address home exercise safety for unilateral paralysis at six months. No study in this set tests a home program, compares exercise types, or follows patients past six months for adverse events like vocal strain or compensation injury.
The few studies that evaluate voice therapy at all use supervised, clinic-based protocols [1, 4]. One 12-week program improved maximum phonation time from about 7 to 23 seconds and reduced jitter from 5.78% to 1.06% [1]. Another found voice therapy matched thyroplasty on most measures at three months, but shimmer did not improve with therapy alone [2]. Neither study reports what happens when patients exercise unsupervised at home, nor do they document any harm from exercises that might force hyperadduction of the healthy fold against the paralyzed one.
The mechanism for harm is plausible. Forcing glottic closure on a poorly coapted larynx can strain the cricothyroid and interarytenoid muscles, worsen asymmetry, and entrench compensatory behaviors that become permanent. Without direct evidence, the safest approach is conservative: brief, low-effort sustained phonation on a comfortable pitch, never pushing past ease. Straw phonation, which loads the supraglottis and reduces impact stress, is a reasonable first choice, though the evidence for it in paralysis is extrapolated from other conditions [5].
My call: no home exercise protocol can be called safe for this condition at six months based on the evidence here. The safest path is supervised therapy first, then gradual home transfer under periodic laryngeal imaging. Confidence: low for safety, low for efficacy.
| Comparison | What the evidence shows |
|---|---|
| Therapy (clinic) vs thyroplasty | Equivalent on most acoustic measures at 3 months [2] |
| Shimmer improvement, therapy | Not significant [2] |
| Home exercise protocols | Not studied at any time point |
| Safety data at 6+ months | None in any study |
