摘要：Plantar pressure is defined as the pressure on the plantar surface on the foot that the human foot experiences during activities. Aim The purpose of this study was to determine the plantar loading during static and dynamic conditions of individuals with and without hearing impairment. METHOD: 33 individuals [hearing impaired group (HI),n=15;20.73±1.83 years;167.73±10.30 cm;BMI=22.46±3.64 kg/m2,and without hearing impairment (WHI),n=18;23.38 ± 4.86 years;164.92 ± 4.94 cm;BMI=20.66 ± 1.50 kg/m2) were participated in this research. Foot plantar pressure assessment during standing and walking were implemented using the EMED-XL (Novel GmbH,Munich,Germany) plantar pressure system. The foot was automatically divided into 19 areas: total foot,hind foot (medial-lateral),midfoot (medial-lateral),forefoot (central-medial-lateral),big toe,second toe,3rd,4th,5th,toes,and metatarsals (MH1: 1st metatarsal head,MH2: 2nd metatarsal head,MH3: 3rd metatarsal head,MH4: 4th metatarsal head,MH5: 5th metatarsal head). The following parameters were calculated for the entire foot: Peak pressure [PP in (kPa)],Mean Pressure [MP in (kPa)],Peak Mean Pressure [PMP in (kPa)],Pressure Time Integral [PTI (kPa.s/cm)],Instant of Peak Pressure [PP(% Rop)],Maximum Force [F in (N)],Maximum Force Normalize to BW [MFNBW (%)],Instant of Maximum Force [IMF (% Rop)],Force Tıme Integral [FTI (N.s/cm2)],Contact Area [CA in (cm2)] and Contact Time [CT in (ms)]. Results All of the measures were examined using independent samples t-test. According to indenpendent samples t-test results there were no significant differences of age,height,and BMI between the HI and WHI groups (p>0.05). HI groups demonstrated increased CT in the hind foot and CT and CA in the forefoot (big and second toes and metatarsals),and MF (% BW),PMP,FTI,MP in the lateral midfoot,CT,MF,MF (% BW) in the hind foot while walking compared to WHI group (p<0.05). HI groups demonstrated increased FTI,PTI,MF,PP,CA,CT,PMP in the big toe,increased CA,MF,FTI in the midfoot,and MF,PMP,FTI,PTI,MP,PP,CA in the lateral and medial midfoot,CA,MF,MP,PMP in the hindfoot while unilateral standing compared to WHI group (p<0.05). CONCLUSION: The results indicated that individuals with hearing impairment exhibit different patterns during barefoot walking and static standing than individuals without hearing impairment. The highest pressure distribution was under the big toe in the HI subjects during unilateral standing. Furthermore,a higher pressure distribution was found under lateral part of foot compared to other mask of foot during walking and unilateral standing in the HI subjects. In the WHI group,the pressure distribution was lower under all parts of foot compared to HI group. It has been suggested that a vestibular function and motor performance of individuals with hearing impairments may result in a more plantar pressure in specific areas of the foot. Therefore,exercise intervention such as that focused on enhancement of sensory integrative postural control abilities is recommended for individuals with hearing impairment who present movement and stability deficits.
