description: Research has been done investigating plantar pressures and pain in subjects with pathologies after the application of orthoses and arch taping. To date, however, no study has been conducted investigating plantar pressures and pain in subjects with plantar fasciitis after the application of the augmented low-dye taping (ALD) in comparison to a heel-pain orthosis (HPO). Therefore, the purpose of this study was to determine the effects of the ALD in comparison to a HPO on pain, peak plantar pressure (PPP), and mean plantar pressure (MPP) under multiple areas of the foot in subjects with plantar fasciitis while walking and jogging. Seventeen subjects, five males (34.8 ± 15.3 years of age, 182 ± I 7.0 cm, 93.89 ± 22. 71 kg) and twelve females (36.8 ± 16.5 years of age, 167 ± 7.0 cm, 70.78 ± 12.51 kg) with plantar fasciitis participated in this study. Subjects had no history of lower extremity surgery and no history of back or lower extremity injury in the last three months other than the condition sought. PPP and MPP were evaluated while walking and jogging after the application of three interventions (control, ALD, HPO) under four areas of the foot: lateral rearfoot (LR), medial rearfoot (MR), lateral forefoot (LF), and medial forefoot (MF). Walking and jogging pressure measurements were recorded 3 times for 30 seconds at a speed range of 0.89-l.34m/s and 2.24-3.13m/s respectively using the PEDAR in-shoe pressure measuring system (Novel, GMBH, St Paul MN, USA). Walking and jogging pain levels were also recorded during each intervention using the Visual Analog Scale (VAS). Two separate 3x4 repeated measures ANOVA were conducted with an alpha level set a priori of p<0.05. Tukey Post Hoc HSD was used to analyze differences in the data. Main outcome measures included walking and jogging PPP and MPP under all areas of the foot as measured in kilopascals (kPa) and pain levels during each intervention while walking and jogging as measured by the VAS. The ALO produced a significant decrease in walking MPP (44.66±14.46) under the LR when compared to the control (57.92±22.18) (p<0.03) and in jogging MPP (55.05±18.27) when compared to the control (67.22±20.95) (p<0.003) and the HPO (68.51± 17 .57) (p<0.003). The HPO significantly increased jogging PPP (156.45±22.88) under the entire foot when compared to the control (134.09±20.53) (p<0.00 I) and ALO (137.85±19.06) (p<0.003). During walking, the HPO (7.12± I 0.08) (p<0.002) and ALO (6.24±5.71) (p<0.006) produced a significant decrease in VAS scores compared to the control (17.32±17.86). Jogging VAS scores also significantly decreased after the application of the HPO (12.15±15.61) (p<0.003) and ALO (10.09±8.87) (p<0.001) compared to the control (26.65±22.38). There were no significant differences between the HPO and ALO during walking and jogging. The ALO produces a significant decrease in MPP under the LR during walking and jogging. Both the HPO and ALO produced statistically and clinically significant decreases in subjects VAS scores while walking and jogging. The HPO and ALO are effective interventions for the immediate relief of plantar fasciitis pain. Future studies should consider the long term effects of these two interventions on plantar pressures, pain, function, and quality of life.
