Dog-assisted physiotherapy in amyotrophic lateral sclerosis: a randomized controlled pilot study.
Manuela Vignolo, Riccardo Zuccarino, Romina Truffelli and 13 others
PMID 38743390WHAT IT FOUND
Adding a therapy dog to balance exercises for two weeks improved walking distance, balance, and mood more than standard physiotherapy alone in people with ALS.
The study was small and short, so it shows promise but does not prove long-term benefit or how to apply it in routine care.
Key findings
01The group with dog-assisted balance exercises showed significantly greater improvements in walking distance, balance, and mood than the control group after two weeks.
02Anxiety and depression scores improved significantly only in the dog-assisted group, while the control group showed no change in mood.
03Both groups received the same underlying neurorehabilitation program; the dog group replaced three morning sessions per week with dog-assisted balance training.

What it does not show
The study was a small pilot with only 60 participants, limiting the reliability of the findings. The intervention lasted only two weeks, so it is unknown if the benefits persist or if the fatigue of ALS progression would offset them over time. There was no mention of a pre-registered primary outcome, meaning the positive results could be due to chance among many measured outcomes. Generalizability is limited by the need for specialized dog handlers and the exclusion of patients with dog allergies or fear. The control group received therapist interaction, which is a strong comparator, but the lack of blinding for participants means expectations could have influenced mood and effort.
Declared interests
The authors declared no conflicts of interest with any financial organization.
The easy way to misread this
Do not interpret this as proof that dog-assisted therapy is superior to standard care for all ALS patients. The study was a small pilot with a short duration, and the positive mood effects were only seen in the dog group, which may be due to the novelty or emotional support rather than a specific therapeutic mechanism. Long-term efficacy and generalizability to more disabled patients remain unproven.
