Purpose This study aimed to investigate the effects of modified lateral talar taping on gait and balance in hemiplegic patients.  Methods It was designed as a crossover study and the test was conducted with 10 subjects. To evaluate gait and balance according to the presence or absence of taping, a 10m walking test(10MWT), limits of stability test(LOST), and gait pattern test were performed.  Results In the 10MWT, the interaction effect was statistically significant in walking time when comparing the situations without taping, with fix taping, and with nonelastic taping (p<0.05). In the LOST comparison, the interaction effect was statistically significant in the plegic side, nonplegic side, anterior, posterior, and total area when comparing the situations without taping, with fix taping, and with nonelastic taping (p<0.05). In the gait patterns comparison, the interaction effect was statistically significant in the velocity, cadence, plegic step, nonplegic step, plegic stride, nonplegic stride when comparing the situations without taping, with fix taping, and with nonelastic taping (p<0.05).  Conclusion The modified lateral talar nonelastic taping was an intervention method that helped improve balance and gait in hemiplegic patients. Therefore, it can be considered one of the taping methods that is helpful for stroke patients with ankle instability in clinical practice.
