{Abstract}: <B>OBJECTIVE: </B>To present a patient with complex regional pain syndrome type 1 (CRPS-I) and improvement of contracture of hand muscles and grip strength after successful treatment with botulinum neurotoxin‑A (BoNT-A).<BR><B>METHODS: </B>A 53-year-old woman with CRPS‑I experienced severe allodynia, swelling and autonomic changes in the left hand after a distal radius fracture. Over the succeeding months, she developed contracture of the left hand muscles which was treated with injection of BoNT‑A into the hand muscles (10 points).<BR><B>RESULTS: </B>In the patient treatment with BoNT‑A an improvement was seen in the hand range of motion (ROM) and grip strength.<BR><B>CONCLUSIONS: </B>Successful results can be obtained with BoNT‑A injection in treatment-resistant CRPS‑I cases which may develop joint contracture.
