Abstract

Few reliable studies have used standardized outcome measures to examine the effectiveness of sensory interventions to treat somatosensory impairment. The aim of this study is to examine the effectiveness of Frenkel’s exercise for improving lower limb sensation, balance, motor function, functional ambulation, and activities of daily living in subacute ischemic stroke patients with impaired proprioception. Methods: This retrospective cohort study enrolled 14 patients suffering subacute ischemic stroke between 7 to 30 days of onset who showed reduced proprioception in the lower limbs. They were divided into two groups: intervention group (performed Frenkel’s exercise, 15 minutes per day, 15 days over a period of 3 weeks, n=7) and control group (received conventional physical therapy instead, n=7). Outcome measurements included the kinesthetic and light touch sensation subscales of the Nottingham Sensory Assessment (NSA) for the lower limb, the Korean version of the Berg balance scale (K-BBS), the Functional Ambulation Classification (FAC), the Motricity Index (MI), and the Korean version of the Modified Barthel Index (K-MBI). Results: Patients in both groups showed significant improvements on the kinesthetic and tactile sensation subscale of the NSA for the lower limb, the K-BBS, the FAC, and the K-MBI, but not the MI, from baseline to post-intervention at 3 weeks. When compared between the two groups, significant improvements were only seen in the kinesthetic sensation subscale of the NSA for the lower limb and the K-BBS (p<0.05). Conclusions: Frenkel’s exercise improves sensory and balance recovery among subacute ischemic stroke patients with impaired proprioception and minimal lower limb motor weakness.
