Hypothesis
Can temporary selective cutaneous anaesthesia improve hand function and sensory perception in workers with vibration-induced neuropathy?
Conclusion
The study found that repeated application of EMLA® cream improved hand function and reduced disability in patients with vibration-induced neuropathy.
Supporting Evidence
- Touch thresholds improved significantly after one year of treatment.
- Eight out of nine participants continued treatment after the first year.
- The treatment also reduced nocturnal numbness in most participants.
Takeaway
This study shows that using a special cream on the arm can help people who have trouble feeling things in their hands because of using vibrating tools.
Methodology
Participants received EMLA® cream treatment on the forearm for 90 minutes, followed by a structured treatment program over eight weeks, with follow-ups for one year.
Potential Biases
Potential bias due to self-reported improvements and lack of blinding.
Limitations
The study is based on a small sample size and lacks a control group.
Participant Demographics
Nine participants, including seven in full-time employment and two retired, with a history of vibration exposure.
