“…Do patients with PD retain the ability to adapt locomotor trajectory in response to PK stimulation as do healthy individuals?-Our results agree with other studies indicating that people with PD retain the ability to modify movements in response to external cues and can adapt motor output in different situations (Stern et al, 1988, Fernandez-Ruiz et al, 2003, Contreras-Vidal et al, 2002, Morris et al, 1994, Zijlstra et al, 1998, Dietz et al, 1995. This is the first study that examines the capability of people with PD to adapt locomotor trajectory in response to stepping on a rotating platform, a task that requires generation of motor patterns for turning during walking.…”

Podokinetic after-rotation in Parkinson disease

2007

Walking on a rotating platform for 15 minutes causes healthy subjects to involuntarily turn when walking without vision. This adaptive response, called podokinetic after-rotation (PKAR), uses the same kinematic patterns as voluntary turning suggesting that PKAR and voluntary turning share common mechanisms. The purpose of this study is to determine whether people with Parkinson disease (PD), a condition that produces substantial disability from turning difficulties, can adapt to the rotating platform. Initial testing of people with PD revealed that most were unable to step on the rotating platform for 15 continuous minutes. We thus tested a less intense version of the paradigm in eight healthy people. On one day, subjects walked on the platform for 15 continuous minutes; on another day, they walked on the platform for three 5 minutes intervals separated by 5 minute rests. After both sessions, subjects rested for 5 min. then walked in place for 30 min. without vision, while we recorded rotational velocity of PKAR. Continuous and interval protocols effectively elicited robust PKAR. We then tested eight subjects with PD and matched controls using the 5 min. interval protocol and recorded PKAR responses for 10 min. There were no significant differences between the PD and control groups. We conclude that PD subjects can adapt to the rotating platform and develop PKAR from interval training. Future studies are needed to determine whether the rotating platform may act as a rehabilitative tool to reinforce motor patterns for turning and alleviate turning difficulties in people with PD.

“…Similar results were obtained in their research by Zijlstra et al [7] who showed signifi cant differences in the length of steps, frequency of steps and gait speed among three groups. The fi rst group consisted of patients with the Parkinson's disease who obtained the following results respectively to the aforementioned parameters: 44cm, 93 steps/min and 0.70 m/s; the second group consisting of healthy people aged 55-60: 69 cm, 106 steps/min and 1.22 m/s, and the third group consisting of young, healthy people aged 25-30: 77 cm, 102.7 steps/ min and 1.31 m/s.…”

Streszczenie:Celem pracy była ocena niektórych parametrów chodu osób z chorobą Parkinsona przy przechodzeniu odcinków prostych określonej trasy i slalomu. Badaniem objęto dwie grupy: grupę badawczą złożoną z 17 chorych na chorobę Parkinsona (średnia wieku 71 lat) i 17-osobową grupę kontrolną reprezentowaną przez osoby zdrowe (średnia wieku 70 lat). Badanie polegało na przejściu trasy, uwzględniającej odcinki proste i slalomu, wytyczonej wg pomysłu autorów pracy. Osoby z chorobą Parkinsona osiągały gorsze parametry chodu w stosunku do osób zdrowych w analogicznym przedziale wiekowym, zwłaszcza na odcinkach slalomu.Słowa kluczowe: choroba Parkinsona, parametry chodu, slalom. Abstract:The aim of the paper was to evaluate chosen gait parameters in patients with the Parkinson's disease while walking on straight sections and slalom of a chosen route. The research covered two groups: the examination group numbering 17 patients with the Parkinson's disease (average age 71 years) and the control group including 17 healthy people (average age 70 years). The examination was based on covering a route consisting of straight sections and slaloms, designed according to the idea of the authors. Patients with the Parkinson's disease achieved worse results in comparison with healthy people of similar age, especially on the slalom distances.

“…A gait pattern with reduced step length has speciWcally been observed in older people with Parkinson's disease (Morris et al 1994;Zijlstra et al 1998), older patients with osteo-arthritis (van den AkkerScheek et al 2007;Hulet et al 2000;McGibbon and Krebs 2002) and in older people with fall incidents (Richardson et al 2005), or fear of falling (Aizen 2001;Nutt 2001).…”

This study evaluated the step length-frequency relationship in physically active community-dwelling older women in order to investigate whether the relationship between these two spatio-temporal gait parameters changes with increasing age. Forty older women in four age groups, i.e. 64-69, 70-74, 75-79 and 80-85 year olds, participated in the study. Subjects walked at Wve diVerent self-selected speeds and while simultaneously performing an additional cognitive and/or upper-extremity motor task. Gait parameters were determined from forward accelerations measured by a tri-axial accelerometer on the lower back. All subjects demonstrated a strong linear relationship between step length and step frequency for walking at diVerent speeds. No evidence for a change in the step length-frequency relationship with age was found, suggesting that there are no diVerences between physically active older women of diVerent age groups regarding the adoption of a "cautious gait", i.e. a gait pattern characterized by a reduced step length.
