De Quervain's Disease in the Acute Phase:a Study Aimed at Evaluating the Effectiveness of Standard Physiotherapy Treatment (HANDGUIDE), Compared to Experimental Treatment After Performing Ultrasound-guided Infiltrative Therapy.
The objective of the study is to compare pain reduction and disability reduction in two groups of patients diagnosed with de Quervain syndrome who will undergo ultrasound-guided infiltrative treatment with corticosteroid as per normal clinical practice:

the control group will subsequently be subjected to a standard treatment based on the European guidelines of the HANDGUIDE group,
the experimental group will subsequently carry out a program of eccentric exercises.
