A stretching splint is defined as being durable medical equipment (or DME). These products are designed such that they are expected to last between 2-3 months of use, depending upon frequency. If you recently received your stretching splint and the velcro isn't holding, it may be defective. If you have had the stretching splint for 4 or more months and use it consistently, this is more of an expected wear and tear. Call our office and we can let you know whether a new splint is recommended.
