Effect of low-frequency electrical stimulation therapy combined with far-infrared irradiation of cervical muscles on whole-body indefinite symptoms in patients with whiplash-associated disorders: a prospective case series - Effect of local modulation of cervical muscles on whole-body indefinite symptoms in patients with whiplash-associated disorders: a prospective case series

The number of symptoms was markedly decreased by the physical therapies during hospitalization. Almost all symptoms showed recovery rates of more than 80% at discharge as compared to those at admission. Although the percentage of patients reporting at least 4 of the representative 22 indefinite symptoms was 99.0% at admission, it decreased to 7.7% at discharge. Sixteen percent of patients recovered completely without any residual symptoms. The mean number of symptoms significantly decreased from 13.1 at admission to 2.0 at discharge. Notably, symptoms other than those in the neck or shoulder recovered to a greater extent than those in the neck or shoulder.
