A single-center, observational, prospective, single dynamic cohort study with before-after design. Treatment with 6 sessions using dry needling with DNHS® (Dry Needling for Hypertonicity and Spasticity) on the spastic muscles of the affected arm in patients with stroke. Spasticity will be assessed by Modifying Modified Ashworth Scale (MMAS), functionality with the Fugl-Meyer scale for the upper limb, motor recovery with Brunnstrom Stages Scale (BSS) and upper limb spasticity pattern (ULP), pain by 10-points Numerical Rating Scale (NRS10) and the quality of life with the Euro QoL 5D survey.
