RESUMEN
OBJECTIVE: There is no existing standard, evidence-based, scientific model for motor ability improvement in Huntington's Disease (HD) patients aimed at maintaining independent gait for as long as possible, or performing activities of daily living, the effectiveness of which would be supported by the results of studies using objective research tools. Under these circumstances, the aim of this study was to analyze the influence of motor ability rehabilitation on the spatial-temporal parameters of gait in HD patients. DESIGN: It was an experimental trial. The studied group consisted of 30 patients (17 women and 13 men) with HD. In hospital conditions, the patients participated in the 3-week motor ability l rehabilitation programme tailored to individual needs. The study group was tested using the Vicon 250 three-dimensional gait analysis system before and after the physical exercise programme. RESULTS: Walking speed after therapy increased for the left lower limb from 1.06 (SD 0.24) [m/s] to 1.21 (SD 0.23) [m/s], and for the right lower limb from 1.07 (SD 0.25) [m/s] to 1.20 (SD 0.25) [m/s]. The cycle length increased after the applied therapy for the left lower limb from 1.17 (SD 0.20) [m] to 1.23 (SD 0.19) [m]. CONCLUSION: The three-week motor ability rehabilitation programme positively influences spatial-temporal gait parameters in HD patients.

Apart from intention tremor essential tremor (ET) patients may display other cerebellar signs, like dysmetria or tandem gait disturbances as well as parkinsonian signs like resting tremor, cogwheel sign, subtle bradykinesia. Previous reports claimed the occurrence of the eye movement abnormalities characteristic for dysfunction of cerebellar dorsal vermis in ET patients with concomitant cerebellar signs. There are no previous reports evaluating the eye movement abnormalities in ET patients with concomitant parkinsonian signs. The objective of this study was to determine the relationship between the occurrence of parkinsonian and cerebellar signs and the oculomotor abnormalities in ET patients. METHOD: Fifty ET patients including 6 (12.0%) patients with concomitant parkinsonian signs (ET-P), 20 (40.0%) patients with cerebellar signs (ET-C), 7 (14.0%) with mixed parkinsonian and cerebellar signs (ET-M), 17 (34.0%) patients with the only tremor (ET-T) together with 42 healthy controls were included to the study. Reflexive, pace-induced and cued saccades were recorded using Saccadometer Advanced. Smooth pursuit and fixation were tested using EOG. RESULTS: Latency of pace-induced saccades was significantly longer in ET-C and ET-M patients compared to ET-T and ET-P patients. Latency of cued saccades was significantly longer in ET-M patients compared to ET-T. There were no significant differences of the eye movement parameters between ET-P patients compared to ET-T patients. CONCLUSION: In ET patient with concomitant cerebellar signs prolonged volitional saccades latency was detected. There are no particular differences in the eye movements in ET patients with concomitant parkinsonian signs compared to ET patients without concomitant signs.

BACKGROUND AND PURPOSE: Huntington's disease (HD) is a neurodegenerative, progressive disorder of the central nervous system which causes significant gait and balance disturbances. This is a pilot study which aims to determine the effects of a physiotherapy programme with use of Proprioceptive Neuromuscular Facilitation (PNF) on gait and balance in HD patients. MATERIAL AND METHODS: 30 HD patients aged 21-60 with genetically confirmed diagnosis participated in the study. Participants followed a 3-week-long PNF-based physiotherapy programme. Gait and balance were evaluated twice in each participant: first at baseline and then after the course of physiotherapy. The following methods were used for gait disturbances: Tinetti Gait Assessment Tool, Up and Go Test, Timed Walking Tests for 10m and 20m (TWT10m, TWT20m). Balance was assessed with use of Berg Balance Scale, Pastor Test and Functional Reach Test. RESULTS: There was a significant improvement in all measures of balance and gait. CONCLUSION: PNF-based physiotherapy is effective and safe in HD patients.

Despite the extensive literature on stroke rehabilitation, there are few studies that comprehensively show non-ambulatory stroke patients. The aim of the study was to explore the dynamics of the change in physical activity (PA), psychological and functional outcomes, and the correlation between them in non-ambulatory patients during early in-patient post-stroke rehabilitation. Measurements were taken on 21 participants at the beginning of and 6 weeks post-conventional rehabilitation with the Barthel Index (BI), Berg Balance Scale (BBS), Trunk Control Test (TCT), Stroke Impact Scale (SIS), General Self-Efficacy Scale, Stroke Self-Efficacy Questionnaire (SSEQ), the original scale of belief in own impact on recovery (BiOIoR), Hospital Anxiety and Depression Scale, Acceptance of Illness Scale and when the patient could walkTime Up & Go and 6 Minute Walk Test. Daily PA was assessed over 6 weeks using a Caltrac accelerometer. Only outcomes for BI, BBS, TCT, SIS, and SSEQ significantly improved 6 weeks post-rehabilitation. PA energy expenditure per day significantly increased over time (p < 0.001; effect size = 0.494), but PA only increased significantly up to the third week. PA change was correlated with BiOIoR post-treatment. Self-efficacy in self-management mediated improvement in SIS. The BiOIoR and confidence in self-management could be important factors in the rehabilitation process.
RESUMEN
BACKGROUND AND PURPOSE: Gait disorders are a common symptom of Parkinson's disease (PD) and can occur in the early stage of the disease. The most characteristic gait disorders in that disease affect pace and cadence. This study was designed to assess spatiotemporal and kinematic gait parameters of patients with PD using the three-dimensional motion analysis system Vicon. MATERIAL AND METHODS: 32 patients (14 women and 18 men; age range: 50-75) treated for PD in the Department of Neurology were studied. The control group consisted of 32 healthy persons (13 women and 19 men, age range: 52-77). Gait analysis using the Vicon 3D system took place in the Biokinetics Laboratory in the Academy of Physical Education in Kraków. The Vicon 3D system enables computerized registration and analysis of motion in three-dimensional space. RESULTS: The analysis of basic spatiotemporal parameters of gait revealed that PD patients had considerably lower walking speed, stride length and cadence and longer time of double support than controls. The assessment of kinematic gait parameters showed that PD patients had decreased motion range in the joints of the lower limbs and began the double support phase earlier and delayed the swing phase when compared to healthy controls. CONCLUSION: Our study shows a difference between PD patients and healthy controls at similar age both in angle changes and in spatiotemporal parameters of gait.

BACKGROUND AND PURPOSE: Intrinsic factors are the main cause of falls in Parkinson's disease (PD). The relation between different symptoms or type of PD and frequency of falls has been unclear so far. The aim of the study was to assess the frequency and causes of falls in postural instability and gait difficulty dominant PD (PIGD) and tremor dominant PD (TD). MATERIAL AND METHODS: The study was performed in 106 patients (51% were women; mean age: 67.7+/-9.8 years; mean disease duration: 6.3+/-3.5 years). The type of the disease was defined according to subscore of UPDRS concerning postural instability, gait difficulty and tremor assessment. The two groups were compared in regard to number and causes of falls, gender, age, disease duration, age at the onset of the disease, UPDRS score, Hoehn and Yahr stage, Schwab and England score, the occurrence of dyskinesia, fluctuations, mental function (MMSE) and depressive mood. RESULTS: There were 76 patients (71.6%) in the PIGD group and 21 (19.8%) in the TD group. There were no significant differences between PIGD and TD regarding age, gender, disease duration, age at the onset of the disease, UPDRS score, Hoehn and Yahr stage, Schwab and England score, mental status and depression. Dyskinesia, fluctuations and gait disorders occurred more often in PIGD. Falls were significantly more common in PIGD-PD (57.9%) than in TD-PD (23.8%) (p=0.03). The number of falls in PIGD- -PD was significantly higher than in TD-PD (mean number of falls in PIGD-PD 3.6+/-6.0 and in T-PD 0.6+/-1.8, p=0.02). Sudden falls were the main cause of falls in both groups. CONCLUSIONS: PIGD patients are significantly more predisposed to falls.

Objective: A number of studies on gait disturbances have been conducted, however, no clear pattern of gait disorders was described. The aim of the study was to characterize the gait pattern in HD patients by conducting analysis of mean angular movement changes the lower limb joints and trunk (kinematics parameters). Methods: The study group consisted of 30 patients with HD (17 women and 13 men). The reference data include the results of 30 healthy subjects (17 women and 13 men). Registration of gait with the Vicon 250 system was performed using passive markers attached to specific anthropometric points directly on the skin, based on the Golem biomechanical model (Oxford Metrics Ltd.). The research group and the control group were tested once. Results: Statistically significant (p < 0.05) angular changes in gait cycle for HD patients were observed in: insufficient plantar flexion during Loading Response and Pre-swing phases; insufficient flexion of the knee joint during Initial Swing and Mid Swing phases; excessive flexion of the hip in Terminal Stance and Pre-swing phases and over-normative forward inclination of the trunk in all gait phases. It should be noted that the group of patients with HD obtained, for all the mean angular movement changes higher standard deviation. Conclusion: A characteristic gait disorder common to all patients with HD occurring throughout the whole duration of the gait cycle is a pathological anterior tilt of the trunk. The results will significantly contribute to programming physiotherapy for people with HD, aimed at stabilizing the trunk in a position of extension during gait.
RESUMEN
OBJECTIVE: The aim of this study was to assess the effect of physical exercise on gait pattern disorders, based on three-dimensional gait analysis in the sagittal plane in a group of people with Parkinson's disease (PD). METHODS: Thirty-two subjects with PD (14 women and 18 men; age: 50-75 years) were qualified for the study, which ran for 3 weeks and included 18 therapeutic sessions. Thirty-five control subjects were included in the research (13 women and 19 men; age: 52-77 years). Gait analysis using the Vicon 3D system took place in the Biokinetics Laboratory. The research group was tested before and after treatment, and the control group was tested once. RESULTS: Comparing the average peak angle changes and average standard time results (% gait cycle) corresponding with angles of movement in the lumbar spine, cervical spine, elbow joint, and shoulder joint, statistically significant changes were observed. The study results are indicative of differences in spatiotemporal parameters and angular changes in gait for both groups. After therapeutic treatment, we observed improvement in the angular range of changes in thorax tilting, but there were no difference between the most affected and less affected side. For the cervical spine, a significant reduction in flexion during dual support was observed. The angular range of changes in shoulder joint was significant only in less affected shoulder during the initial contact (F1), terminal stance (F4), and terminal stance (F8) phases of gait (p < 0.05). After therapeutic treatment, significant angle and setting changes in the most affected limb of the elbow joint occurred during the initial contact and terminal swing phases (F1, F8). In the terminal stance phase (F4), an increase in range of motion by about ±4° was observed (p < 0.05). CONCLUSION: Exercise therapy slightly increased the range of movement in the examined joints of PD's patients. Results of pathological walking patterns occurring prior to treatment improved after treatment and moved closer to the physiological gait pattern.
RESUMEN
Idiopathic Parkinson's Disease (PD) is a progressive condition with gait disturbance and balance disorder as the main symptoms. Previous research studies focused on the application of Rhythmic Auditory Stimulation (RAS) in PD gait rehabilitation. The key hypothesis of this pilot study, however, assumes the major role of the combination of all three Neurologic Music Therapy (NMT) sensorimotor techniques in improving spatio-temporal gait parameters, and postural stability in the course of PD. The 55 PD-diagnosed subjects invited to the study were divided into two groups: 30 in the experimental and 25 in the control group. Inclusion criteria included Hoehn and Yahr stages 2 or 3, the ability to walk independently without any aid and stable pharmacological treatment for the duration of the experiment. In order to evaluate the efficacy of the chosen therapy procedure the following measures were applied: Optoelectrical 3D Movement Analysis, System BTS Smart for gait, and Computerized Dynamic Posturography CQ Stab for stability and balance. All measures were conducted both before and after the therapy cycle. The subjects from the experimental group attended music therapy sessions four times a week for 4 weeks. Therapeutic Instrumental Music Performance (TIMP), Pattern Sensory Enhancement (PSE) and RAS were used in every 45-min session for practicing daily life activities, balance, pre-gait, and gait pattern. Percussion instruments, the metronome and rhythmic music were the basis for each session. The subjects from the control group were asked to stay active and perform daily life activities between the measures. The research showed that the combination of the three NMT sensorimotor techniques can be used to improve gait and other rhythmical activities in PD rehabilitation. The results demonstrated significant improvement in the majority of the spatiotemporal gait parameters in the experimental group in comparison to the control group. In the stability tests with eyes closed, substantial differences were revealed, indicating improvement of proprioception (the sense of body position and movement). These findings suggest a new compensatory strategy for movement and postural control through the use of the auditory system.
RESUMEN
Planning and verification of progress of efficacious physiotherapeutic effect on Parkinson's disease depends notably on the right identification of areas and scope of dysfunction of motoric systems. Biomechanical evaluation of motoric organ disability made by means of three-dimensional motion analysis using the "Vicon" system can make it considerably easier. A sample of three patients (two women and one man of average age of sixty-four) with idiopathic parkinsonism has been examined for the purpose of this evaluation. Based upon results of the three-dimensional motion analysis of these patients, dominant individual movement disorders were determined and individual therapeutic rehabilitation using the PNF method was planned. Within therapy, using the PNF method, they applied special techniques using motor patterns for the pelvis, upper and lower limbs in order to improve movement through an approach of assessed parameters to the biomechanical standard. After three weeks of therapy, specific characteristics of gait were examined again. On the basis of research results before therapy, it was found that these patients had none or limited scope of plantar flexion of feet, excessive dorsal flexion of feet, lengthened duration of stance phase, considerable excessive external rotation of shanks and excessive anteversion of the pelvis during gait cycle. Also big differences in values for spatiotemporal parameters (such as walking speed and frequency, stride length and time of single limb support) between the patients and healthy people were observed. After therapy, there has not been a marked variability in the scope of angular changes to the above-mentioned dysfunction. Only proportions between the duration of stance phase and swing phase have improved noticeably, so that they have directly resulted in better rhythm of gait. They have considerably approached the standards of frequency and speed (p = 0.05). However, stride length and duration of single limb support has not changed significantly.
