Acceleration Data

A cardinal feature of freezing of gait (FOG) is high frequency (3–8 Hz) oscillation of the legs, and this study aimed to quantify the temporal pattern of lower-body motion prior to and during FOG. Acceleration data was obtained from sensors attached to the back, thighs, shanks, and feet in 14 Parkinson’s disease patients performing timed-up-and-go tasks, and clinical assessment of FOG was performed by two experienced raters from video. A total of 23 isolated FOG events, defined as occurring at least 5 s after gait initiation and with no preceding FOG, were identified from the clinical ratings. The corresponding accelerometer records were analyzed within a 4 s window centered at the clinical onset of freezing. FOG-related high-frequency oscillation (an increase in power in the 3–8 Hz band >3 SD from baseline) followed a distal to proximal onset pattern, appearing at the feet, shanks, thighs, and then back over a period of 250 ms. Peak power tended to decrease as the focus of oscillation moved from feet to back. There was a consistent delay (mean 872 ms) between the onset of high frequency oscillation at the feet and clinical onset of FOG. We infer that FOG is characterized by high frequency oscillation at the feet, which progresses proximally and is mechanically damped at the torso.

BACKGROUND: Recent studies have suggested that cognitive-motor dual-task (DT) training might improve gait performance, locomotion automaticity, balance, and cognition in patients with Parkinson’s disease (PD). OBJECTIVE: We aimed to investigate the efficacy of cognitive-cycling DT training in patients with early-stage PD. METHODS: Participants were scheduled to perform cognitive tasks simultaneously with the cycling training twice per week for eight weeks for a total of 16 sessions during their on-states. Clinical assessments were conducted using the unified Parkinson’s disease rating scale (UPDRS), modified Hoehn and Yahr stage, Timed Up and Go (TUG) test, gait and cognitive performances under dual-task paradigm, the new freezing of gait questionnaire, Schwab and England Activities of Daily Living scale, 39-item Parkinson’s disease questionnaire, and cognitive performance. RESULTS: Thirteen eligible patients were enrolled in the study. The mean age was 60.64±5.32 years, and the mean disease duration was 7.02±3.23 years. Twelve PD patients completed 16 serial cognitive-cycling sessions for two months. After 16 sessions of training (T2), the UPDRS III scores improved significantly in both the off- and on-states, and TUG were significantly less than those at pretraining (T0). During both the single-task and the DT situations, gait performance and spatial memory cognitive performance significantly improved from T0 to T2. CONCLUSION: The present study demonstrated that cognitive-cycling DT training improves the motor functions, gait and cognitive performances of PD patients.

Freezing of gait (FoG) is among the most disabling symptoms of Parkinson’s disease (PD) patients. Recent studies showed that action observation training (AOT) with repetitive practice of the observed actions represents a strategy to induce longer-lasting effects compared with standard physiotherapy. We investigated whether AOT may improve FoG and mobility in PD, when AOT is applied in a group-based setting. Sixty-four participants with PD and FoG were assigned to the experimental (AO) or control groups and underwent a 45-minute training session, twice a week, for 5 weeks. AOT consisted in physical training combined with action observation whereas the control group executed the same physical training combined with landscape-videos observation. Outcome measures (FoG questionnaire, Timed Up and Go test, 10-meter walking test, and Berg balance scale) were evaluated before training, at the end of training, and 4 weeks later (FU-4w). Both groups showed positive changes in all outcome measures at posttraining assessment. Improvements in FoG questionnaire, Timed Up and Go test, and Berg balance scale were retained at FU-4w evaluation only in the AOT group. AOT group-based training is feasible and effective on FoG and motor performance in PD patients and may be introduced as an adjunctive option in PD rehabilitation program.

Freezing of gait (FOG) in Parkinson’s disease (PD) is a highly disabling symptom which impacts quality of life. The New FOG Questionnaire (NFOG-Q) is the most commonly used tool worldwide to characterize FOG severity in PD. This study aims to provide a German translation of the NFOG-Q and to assess its validity in people with PD. The questionnaire was translated using forward-backward translation. Validity was tested in 57 PD patients with FOG via Cronbach’s alpha for internal consistency and Spearman correlations with several clinical measures to quantify disease severity, mobility, fall risk, and cognitive state for convergent and divergent validity. The German version of the NFOG-Q shows good internal consistency (Cα = 0.84). Furthermore, the NFOG-Q score was significantly correlated with the MDS-UPDRS III, H&Y stage, Timed Up and Go test, and the subjective fear of falling (FES-I). The lack of correlation with cognition (MoCA) points towards good divergent validity. This study provides a German version of the NFOG-Q which proved to be valid for the assessment of FOG severity in individuals with PD.

Objective To evaluate the effects of body weight-supported overground gait training (BWSOGT) on motor abilities, such as gait and balance, in patients with Parkinson’s disease (PD). Design Retrospective case-controlled observational study with a 4-week follow-up. Setting Inpatient rehabilitation. Participants We selected 37 of 68 patients with PD. Inclusion criteria were (1) Hoehn & Yahr stage II–IV, (2) no medication adjustment during the study period, (3) at least 1 week since last medication adjustment, and (4) ability to walk more than 10 meters on their own. Exclusion criteria were (1) cerebrovascular disease or other complications affecting movement, (2) difficulty in measurement, (3) early discharge, (4) medication change during the study, and (5) development of complications. Interventions Patients were divided into two groups. Patients in Group I underwent 20 minutes of BWSOGT with a mobile hoist in addition to the standard exercises; Group II performed 20 minutes of gait training in place of BWSOGT. In both groups, training was performed for a total of 15 times/4 weeks. Main outcome measure(s) Participants were evaluated using the Unified Parkinson’s Disease Rating Scale total, part II, and part III; 10-m walk test; velocity; stride length; 6-minute walk test; timed up and go test; Berg Balance Scale; and freezing of gait before and after the intervention. Results There were significant decreases in the Unified Parkinson’s Disease Rating Scale total, part II, and part III in both groups; however, 6-minute walk test, timed up and go test, and freezing of gait results only improved in Group I. Conclusions BWSOGT for patients with PD improves gait ability and dynamic balance more than standard gait training.

Background. Freezing of Gait (FOG) is a disabling parkinsonian symptom. The Freezing of Gait Questionnaire (FOG-Q) reliably detects FOG in patients with Parkinson’s disease (PD).Objectives. The aim of this study was to develop a German translated version of the FOG-Q and to assess its validity.Methods. The translation was accomplished using forward-backward-translation. The construct validity of the FOG-Q was examined in twenty-seven German native speaking PD patients. Convergent validity was assessed by correlating the FOG-Q with the Movement Disorder Society-Unified Parkinson’s Disease Rating Scale (MDS-UPDRS) II-III, the Parkinson Disease Questionnaire 39 (PDQ-39), and the Timed Up and Go Test (TUG). Divergent validity was assessed by correlating the FOG-Q with the MDS-UPDRS I. The internal consistency was measured using Cronbach’s alpha (Cα).Results. A good internal structure of the FOG-Q was found (Cα=0.83). Significant moderate correlations between the FOG-Q and the MDS-UPDRS item 2.13 (freezing) (rs=0.568,P=0.002) and between the FOG-Q and the PDQ-39 subscale mobility (rs=0.516,P=0.006) were found. The lack of correlation with the MDS-UPDRS I demonstrated good divergent validity.Conclusion. The German FOG-Q is a valid tool to assess FOG in German native speaking PD patients.
