To explore the occurrence of and risk factors for spasticity until six months after first-ever stroke.
Forty-nine patients were examined at day 2-10, at one month, and at six months. The Modified Ashworth Scale (MAS) was used to assess resistance to passive movements. A comprehensive clinical examination was performed to identify other positive signs of the upper motor neuron syndrome, in accordance with a broader definition of spasticity, and to evaluate if spasticity was disabling. Neurological impairments were determined by use of the National Institutes of Health Stroke Scale and global disability by use of the modified Rankin Scale.
Spasticity was present in two patients (4%) at day 2-10, in 13 patients (27%) at one month, and in 11 patients (23%) at six months. Severe paresis at day 2-10 was associated with a 10-fold higher risk for spasticity at one month (OR=10, 95% CI 2-48). Disabling spasticity was present in one patient at one month and in 6 patients (13%) at six months.
Spasticity according to MAS usually occurs within one month and disabling spasticity later in a subgroup. Severe paresis of the arm is a risk factor for spasticity.
