Pain Perception of Children and Youth Receiving Non-sedated Botulinum Toxin-A Injections Using the Buzzy®

The use of Botulinum toxin injections (BoNT-A) has become a standard therapy for children and youth who suffer from stiffness of their muscles due to a neurological problem. These injections are given into each muscles which require treatment, which often means receiving multiple injections in one session. Intramuscular injections are typically painful. Treatment can be provided unsedated and then should incorporate distraction and relaxation techniques, or can be alternatively be provided with the use of sedation. To improve the pain experience the investigators want to assess the feasibility and impact on the pain perception when using a vibration device called the Buzzy during BoNT-A injections. The Buzzy creates a vibration that is applied over the injection site for 30 seconds before the injection and will be continued just above the injection site during the injection. The Buzzy has been shown to help reduce pain in procedures such as i.v. insertions and immunizations, but has not been tested in children and youth receiving multiple BoNT-A injections.
