Hand-Arm Vibration Syndrome (HAVS), also known as Vibrating White Finger, is an occupational disease caused by long-term exposure to vibrating power tools. Vascular (Raynaud's-like blanching), neurological (numbness, tingling), and musculoskeletal symptoms develop progressively. PEMF therapy supports vascular function, nerve recovery, and inflammation reduction — directly relevant to all three HAVS symptom domains. Industries affected: construction, ground works, scaffolding, mining, forestry, dental, mechanical engineering. Reportable under RIDDOR.
Quick facts
- What it is: Occupational vascular + neurological damage from vibrating tools
- Industries: Construction, scaffolding, mining, forestry, dental, engineering
- Reportable: Yes — RIDDOR
- PEMF mechanism match: Vascular + neurological + inflammation — all 3 PEMF strengths
- Sessions: 2–3× per week for 8–12 weeks, then maintenance
Why this injury happens in this sport
HAVS symptoms develop over years of exposure. Early-stage (Stockholm score 1) shows occasional finger blanching. Late-stage shows severe blanching, persistent numbness, grip weakness, and functional impairment. Once advanced, recovery is slow and often incomplete — making early intervention critical.
Recovery and return to sport
Reduce or eliminate vibration exposure (statutory employer duty). Warming protocols. PEMF 2–3× per week directly over hands/forearms for 8 weeks. Vascular and nerve symptoms often improve significantly with consistent treatment. Late-stage recovery is slower but PEMF still supports symptom management.
Contraindications
Standard PEMF contraindications: pacemakers, defibrillators, cochlear implants, insulin pumps, electronic implants; active malignancy without specialist clearance; pregnancy (over the abdomen); active infection; epilepsy without GP clearance.
Frequently asked questions
Can PEMF reverse HAVS damage?
Early-stage HAVS often improves substantially with PEMF + exposure reduction. Late-stage damage may be permanent but PEMF still helps with symptom management.
Will my employer cover the treatment?
HAVS is reportable under RIDDOR and is an industrial disease. Some employers fund treatment; ask via your H&S department or union.
Is HAVS the same as Raynaud's?
HAVS includes Raynaud's-like vascular symptoms but also nerve and musculoskeletal involvement. HAVS is occupational; primary Raynaud's is constitutional.
Can I claim industrial injuries benefit?
Possibly — HAVS is a prescribed disease (A11). Speak to a trade union or solicitor specialising in industrial disease.
How quickly will PEMF help?
Most patients report improvement within 4–6 weeks of consistent twice-weekly sessions. Vascular symptoms often respond fastest.
