Introduction:Parkinson's disease (PD) is a progressive neurodegenerative disease in whichdopaminergic neuron loss is seen causing motor and non-motor symptoms. “Frozen of gait(FOG), which is defined as a short-term, episodic absence or marked decrease in the progressionof the feet despite the desire to walk, is one of the gait disorders seen in PD.
Materials and Methods:Twenty individuals with idiopathic PD (10 FOG, 10 non-FOG) wereincluded in the study. Demographic and clinical information of the individuals were recordedand evaluated with the Unified Parkinson's Disease Rating Scale (UPDRS) and theComputerized Gait Evaluation System. The Mann Whitney U test was used because the datawere not normally distributed.
Results:Individuals were similar in terms of sociodemographic characteristics, duration ofdisease, and UPDRS motor examination sub-parameters (p>0.05). The UPDRS total andActivities of Daily Living sub-parameter scores were higher in the FOG group than in the non-FOG group (p<0.05). When the mean foot pressure distributions in static stance were analyzed,the amount of load transferred to the right-left and anterior-posterior feet was similar in bothgroups. In the foot pressure distributions during walking, the posterior-foot pressure distributionwere similar (p>0.05), while the anterior-foot pressure values were found to be lower in theFOG group than in the non-FOG group (p<0.05).
Discussion:The decrease in the amount of load transferred to the posterior-foot during walkingin both groups supports the decrease in heel strike in PD. When the anterior-foot pressure valueswere examined during walking, it was observed that the FOG group transferred less load. It wasobserved that the freezing phenomenon reduced the amount of load transferred to the anterior-foot during walking and the FOG group could not perform the pushing phase adequately. In theliterature, it has been shown that increasing anterior-foot load increases freezing episodes andpatients can reduce the amount of load on the anterior-foot to avoid freezing. Therefore, wethink that the FOG group may have reduced the anterior-foot load during the analysis to ensuregait continuity on the treadmill and to avoid freezing.
Conclusion:It was observed that the amount of load on the posterior-foot, that is, the heel strike,decreased in PD, while the amount of load on the anterior-foot, that is, the push-off in walking,decreased in the group FOG. Our study results will shed light on the physiotherapy programsof individuals with PH and future studies by giving important outputs for the PH clinic
