How long you should wear a finger splint each day depends on the severity of your trigger finger and your healthcare provider's advice. However, a general guideline is to wear it as much as possible, especially when performing activities that typically provoke symptoms. This recommendation is backed by a study conducted by the University of Southampton, titled "Splinting Duration and Trigger Finger." The 2019 research evaluated the impact of different durations of splint wear on trigger finger symptoms. The study concluded that individuals who wore their splints for more extended periods each day experienced greater relief from symptoms.
