Abstract:
Objective To investigate the effects of lower limb functional training on foot-ground contact area,plantar pressure and impulse in patients with diabetic foot,and provide theoretical and practical basis for the prevention and control of diabetic foot.Methods A total of 100 subjects with diabetic foot aged 50 to 80 years old and 50 healthy subjects were included.The 100 subjects with diabetic foot were divided into a lower limb functional training group(HDG group),and a no-training positive control group(HCG group),each with 50 subjects,and 50 healthy subjects as a negative control group(NCG group)to compare the effects of the lower limb functional training interventions.The HDG group received the 12-week lower limb functional training intervention 4 times/week,60 minutes/time.The NCG group and HCG group received routine care and normal life.Foot-ground contact area,plantar pressure and impulse metrics were tested and analyzed with the Intelligent Foot Detection Scanner.Results After the intervention,the foot-ground contact area at toe 1(T1),metatarsal 1(M1),mid foot(MF),heel medial(HM),and heel lateral(HL)region of the left and right foot in the HDG group was reduced,and the foot-ground contact area at toe 2-5(T2～5),metatarsal 2-3(M2～3),metatarsal 4-5(M4～5),and mid foot(MF)region of the left and right foot were significantly increased.After the intervention,plantar load,peak pressure,mean pressure,and forefoot to forefoot load ratio were significantly reduced in the left and right foot of the HDG group.After the intervention,impulses at T1,M1,M2～3,M4～5,medial,and lateral MF region of the left and right foot in the HDG group were significantly decreased in,and impulses at T2～5,HM,and HL region of the left and right foot in the HDG group were significantly increased.Conclusions After functional training of the lower limbs,the abnormalities of plantar contact area in patients with diabetic foot were improved,the peak plantar pressure was reduced,the plantar pressure impulse was redistributed,and the occurrence of foot ulcers caused by localized overloading in gait was mitigated and delayed.This study can help to provide a reference for different rehabilitation and exercise methods of lower limbs for patients with diabetic foot.
