Dolphin Therapy for Down Syndrome: Evidence Review

Dolphin-assisted therapy (DAT) involves structured interactions with dolphins, claimed to improve social, communicative, and motor skills in neurodevelopmental disorders.

Current Evidence

• No high-quality RCTs demonstrate specific efficacy for Down syndrome.
• Studies are small, uncontrolled, lack blinding, and rely on parent/therapist report.
• Observed benefits (mood, engagement) may stem from novelty, water environment, therapist attention – not dolphins per se.
• Systematic reviews (e.g., Marino & Lilienfeld, 2007; Humphries et al., 2018) conclude no credible evidence for DAT as a therapeutic intervention.

Risks & Ethical Concerns

• Animal welfare: captivity stress, injury risk to dolphins and participants.
• Infection transmission (brucellosis, fungal, viral).
• High cost; diverts resources from evidence-based therapies (speech, OT, PT, ABA).
• False hope for families.

Recommendation

Major organizations (AAP, ASHA, NDSS) do not endorse DAT. Prioritize proven, individualized interventions. If families seek animal interaction, consider accredited therapy animal programs (dogs, horses) with established safety/efficacy standards.
