This study compared interview and telephone surveys to select the better method for regularly estimating nationwide vaccination coverage rates in Korea. Interview surveys using multi-stage cluster sampling and telephone surveys using stratified random sampling were conducted. Nationwide coverage rates were estimated in subjects with vaccination cards in the interview survey. The interview survey relative to the telephone survey showed a higher response rate, lower missing rate, higher validity and a less difference in vaccination coverage rates between card owners and non-owners. Primary vaccination coverage rate was greater than 90% except for the fourth dose of DTaP (diphtheria/tetanus/pertussis), the third dose of polio, and the third dose of Japanese B encephalitis (JBE). The DTaP4: Polio3: MMR1 fully vaccination rate was 62.0% and BCG1:HepB3:DTaP4:Polio3:MMR1 was 59.5%. For age-appropriate vaccination, the coverage rate was 50%-80%. We concluded that the interview survey was better than the telephone survey. These results can be applied to countries with incomplete registry and decreasing rates of landline telephone coverage due to increased cell phone usage and countries. Among mandatory vaccines, efforts to increase vaccination rate for the fourth dose of DTaP, the third dose of polio, JBE and regular vaccinations at recommended periods should be conducted in Korea.

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.
