Neurorehabilitation of Sequence Effect in Parkinson's Disease
Destination Sequence Effect Modifications After a 4-week Rehabilitation Program in Parkinson's Diseases Patients
調査の概要
詳細な説明
Gait impairment and freezing of gait (FOG) represent common and disabling symptoms of Parkinson's disease (PD). The antiparkinsonian therapy positively modulates a subset of gait parameters, such as speed of gait and stride length, while its impact on FOG is limited. Growing evidence supports the efficacy of neurorehabilitation in the treatment of PD across all phases of the disease. In the last years, the advent of reliable wearable devices has prompted the widespread study of several parameters of the parkinsonian gait in both clinical and research settings.
The sequence effect (SE), defined as a reduction in amplitude of repetitive movements, is a common clinical feature of several tasks of patients affected by PD, being identifiable in early as well as advanced stages of the disease. During walking, SE manifests as a step-by-step reduction in step length when approaching a turn or gait destination (destination sequence effect - dSE). SE is specifically pronounced in PD patients affected by FOG, and it arises immediately before a FOG episode induced by a turning or a dual-task.
SE may be acutely modulated by several rehabilitative strategies such as split-belt treadmill and reinforcement of visual cues, but not by repetitive transcranial magnetic stimulation (rTMS), antiparkinsonian drugs administration, and attention strategies did not influence the SE, the evidence on the role of neurorehabilitation on gait SE improvement and retention is extremely scarce.
The investigators plan to enroll 43 subjects according to sample size calculation. Patients will be divided into two groups: patients with freezing of gait (FOG) and without FOG. The subjects will be divided into two groups: 1) patients with freezing of gait (PD+FOG), or 2) patients without freezing of gait (PD-FOG). FOG phenotype is defined as: a score between 1 and 4 at either item "2.13 Freezing" or item "3.11 Freezing of gait" of the Unified Parkinson Disease Rating Scale (UPDRS).
All patients will be treated with a standardized 4-week rehabilitation in-hospital program. At hospital admission (T0), patients who fulfill inclusion/exclusion criteria will be tested with instrumental gait analysis and administration of a set of the following clinical scales: rating of PD related motor disability with the Unified Parkinson's Disease Rating Scale - part III (UPDRS-III); rating of functional independence as measured through the Functional Independence Measure (FIM); and rating of dependence in activity of daily living according to Barthel Index.
After that, patients will be treated with 90-minute daily rehabilitative sessions, 6 days a week (Monday through Saturday) for four weeks (passive, active-assisted, and active exercises, isotonic and isometric exercises for the major muscles of the limbs and trunk, cardiovascular warm-up exercises, muscle stretching exercises for functional purposes, balance training exercises, specific motor exercise for hypokinesia, and 45 minutes of overground gait training delivered without devices or cueing). The rehabilitation program will be the same in PD+FOG and PD-FOG groups. At the end of the rehabilitation program (T1), the patients will complete the study procedure with a second instrumental gait analysis evaluation and the administration of the same set of clinical scales. No modifications of the drug regimen were allowed during the study.
The gait analysis will be performed with wearable, wireless, inertial system, secured to the back of the patients between L5 and S1 vertebrae. All subjects will be recorded in the morning (between 9:00 a.m. and 11:00 a.m.) and in the ON condition. The investigators plan to record a walk, at a comfortable pace, of 20 meters. The subjects will stop independently at the end of the 20-meter pathway, clearly marked by a straight line on the ground. Gait assessments with episodes of freezing of gait or pauses will be discrded. For each subject, three optimal performed gait assessments will be recorded. Regarding gait parameters the investigators will record: speed (m/s), cadence (steps/minute), stride length (meter), step length (meter), stride duration (second), single support, double support, swing duration, stance duration (percentage stride distribution). The destination Sequence Effect (dSE) will be computed as a regression slope (β) of step length according to a previously described and validated methodology where step length is plotted against step number. Briefly, the length of the last six steps ahead of the final stride are plotted against the step number, and the linear regression slope (β) will represent a measure of dSE. In addition, the intercept (I) of the regression curve will be used as an indirect measure of gait hypokinesia. For each group, the relationship between gait hypokinesia and sequence effect is expressed by the function of the linear regression as follow: y = β (x) + I.
