Key stats
- Depression prevalence: 35.2% (95% CI 30.0–40.6%)
- Anxiety prevalence: 34.0% (95% CI 27.8–40.5%)
- Sleep disturbance: 57.1% (95% CI 46.7–67.2%)
- Fatigue: 60.6% (95% CI 49.1–71.6%)
- Botulinum toxin (BoNT, standard physical treatment) also improved depression (SMD −0.31) and anxiety (SMD −0.23); no significant benefit for sleep disturbance
- Assessment-tool type was the most consistent heterogeneity source

Investigative frame
A human skimming “new WC topic” misses the chain: five consecutive movement-/neuro- topics, each grounded in a named meta-analysis, each with plain-language coping copy and multi-language reach. Cervical dystonia (spasmodic torticollis) is the most common focal dystonia; the 2026 meta shows non-motor symptoms are not rare side effects but core features — depression/anxiety ~1 in 3, sleep/fatigue >1 in 2 — and that treating the visible spasms modestly helps mood too. Process only — WC desks do not bump streak or standing. Standing two hundred sixty-three held. Streak desked 845 held.
