Effects of perceptive rehabilitation on balance control in patients with Parkinson's disease

Is there any relationship between scoliosis, cervical pain and postural imbalance in Parkinson's disease? A cross-sectional pilot study

Parkinson's disease (PD) is defined by progressive worsening of gait, posture, and balance, as well as disability in daily life activities, and improvement in chronic musculoskeletal pain, particularly neck pain associated with worsening of balance. The study's goal is to look into the relationship between scoliosis, balance, and cervical pain in Parkinson's disease patients. Cross-sectional, pilot study. The study included 16 Parkinson's patients. Neck cervical pain was measured using the pain visual analogue scale and the short form McGill pain questionnaire, while dynamic balance was assessed using static balance, Tinetti, Berg Balance, and the Short Physical Performance Battery scales (SPPB). Cobb angles are measured on a whole-spine standard X-ray to assess spinal scoliosis.An observational statistical analysis was performed with patients subdivided into two groups: non-scoliosis (NS) and true scoliosis (TS) based on whether they presented a Cobb's angle below or ≥10°. Neck pain was reported by 37% (n=3) of participants in the NS group versus 50% (n=4) in the TS group. Neck pain was more prevalent in patients with a disease duration of less than 48 months (n=6; 75.0% vs n=1; 12.5%; p-value < 0.05). Scoliosis, cervical pain, and postural imbalance are all significant but often overlooked Parkinson's disease complaints.

Validation of SuPerSense, a Sensorized Surface for the Evaluation of Posture Perception in Supine Position

This study aimed to validate a sensorized version of a perceptive surface that may be used for the early assessment of misperception of body midline representation in subjects with right stroke, even when they are not yet able to stand in an upright posture. This device, called SuPerSense, allows testing of the load distribution of the body weight on the back in a supine position. The device was tested in 15 patients with stroke, 15 age-matched healthy subjects, and 15 young healthy adults, assessing three parameters analogous to those conventionally extracted by a baropodometric platform in a standing posture. Subjects were hence tested on SuPerSense in a supine position and on a baropodometric platform in an upright posture in two different conditions: with open eyes and with closed eyes. Significant correlations were found between the lengths of the center of pressure path with the two devices in the open-eyes condition (R = 0.44, p = 0.002). The parameters extracted by SuPerSense were significantly different among groups only when patients were divided into those with right versus left brain damage. This last result is conceivably related to the role of the right hemisphere of the brain in the analysis of spatial information.

Postural Abnormality in Parkinson's Disease: A Large Comparative Study With General Population

Background

Postural abnormalities in Parkinson's disease (PD) patients and unimpaired elderly are not well differentiated. Factors related to postural abnormality associated with PD are controversial.

Objective

We assessed differences in postural change between PD patients and unimpaired elderly and elucidated factors related to abnormal posture in PD patients.

Methods

We measured the dropped head angle (DHA), anterior flexion angle (AFA), and lateral flexion angle (LFA) of the thoracolumbar spine of an unprecedented 1,117 PD patients and 2,732 general population participants (GPPs) using digital photographs. Two statistical analyses were used for elucidating factors related to these angles.

Results

In GPPs, age was correlated with DHA, AFA, and LFA. DHAs, AFAs, and LFAs of PD patients and age-matched GPPs were 21.70° ± 14.40° and 13.13° ± 10.79°, 5.98° ± 12.67,°and - 3.82° ± 4.04°, and 0.86° ± 4.25° and 1.33° ± 2.16°, respectively. In PD patients, factors related to DHA were age, male sex, and H & Y stage during ON time. Factors related to AFA were age, duration of disease, H & Y stage during ON and OFF times, pain, vertebral disease, and bending to the right. A factor related to LFA was AFA.

Conclusions

DHA and AFA of GGPs correlated with age and were larger in PD patients than those with in GPPs. Some PD patients showed angles far beyond the normal distribution. Thus, factors associated with disease aggravation affected postural abnormality in PD patients.

Speed and temporal adaptations during nonmotorized treadmill walking in Parkinson disease and nondisabled individuals

Few studies have explored the potential of gait analysis and training in nonmotorized treadmill (NMT) in Parkinson's disease (PD) patients. We investigated (a) the walking strategy adopted by patients with PD on NMT and (b) how balance may influence spatiotemporal gait parameters. We enrolled 12 patients with PD of modified Hoehn and Yahr stage 2-3 and 13 nondisabled individuals as controls. All participants were evaluated using Tinetti's performance oriented mobility assessment scale, freezing of gait questionnaire, modified falls efficacy scale, and the timed up and go test. They were asked to ambulate with comfortable and maximal speeds on the NMT. The gait parameters acquired on the NMT included walking speed, cadence (CAD), step length, and vertical ground reaction force, which were calculated for intragroup and intergroup comparisons. The PD group took on with higher contribution of CAD and less contribution of step length to increase walking speed as compared with control group. The postural stability is correlated significantly positively to the CAD at the setting of maximal speed in the PD group. Moreover, a significantly lower ratio of vertical ground reaction force/body weight was noted in the PD group during both comfortable and maximal walking speeds compared with the nondisabled controls. Our study outcomes clearly support the perceived benefits of NMT to differentiate spatiotemporal gait parameters between PD and controls. NMT may potentially be useful to evaluate the recovery of physical activities in PD receiving medications and/or rehabilitation.

Impact of Mézières Rehabilitative Method in Patients with Parkinson's Disease: A Randomized Controlled Trial

The aim of this study was to assess the efficacy of Mézières method in improving trunk flexibility of the back muscles and balance in patients with Parkinson's disease (PD). Materials and Methods. Thirty-six patients were randomized into 2 groups: the Mézières treatment group and the control group (home exercise group). The primary outcome was the improvement in balance per the Berg Balance Scale (BBS) and the trunk flexibility of the back for the anterior flexion trunk test. Also, we evaluated pain, gait balance for the Functional Gait Assessment (FGA), disease-related disability for the Modified Parkinson's Activity Scale and the Unified Parkinson's Disease Rating Scale (UPDRS), the quality of life, and the functional exercise capacity. All the measures were evaluated at baseline (T0), at the end of the rehabilitative program (T1), and at the 12-week follow-up (T2). Results. In the Mézières group, the BBS (p < .001) and trunk flexion test (p < .001) improved significantly at T1 and remained the same at T2. Between groups, significant changes were reported in FGA (p = .027) and UPDRS Total (p = .007) at T1 and in FGA (p = .03) at T2. Conclusion. The Mézières approach is efficacious in improving the flexibility of the trunk and balance in PD patients.

A New Rehabilitation Tool in Fibromyalgia: The Effects of Perceptive Rehabilitation on Pain and Function in a Clinical Randomized Controlled Trial

Introduction/Objective. Fibromyalgia might benefit from a specific tactile and proprioceptive rehabilitation approach. The aim of this study was to perform a randomized controlled trial to determine the efficacy of perceptual surfaces (PS) and physical exercises with regard to chronic pain and physical function in fibromyalgia compared with a control group. Methods. Data from 54 females (18–60 years old) with a diagnosis of fibromyalgia and scoring >5 on the visual analog scale were divided into 3 groups and analyzed: group treated with perceptual surfaces (PS-group), physical exercises group (PE-group), and control group (CG). The Fibromyalgia Impact Questionnaire (FIQ), Health Assessment Questionnaire (HAQ), and Fibromyalgia Assessment Scale (FAS) were administered at baseline (T0), at the end of the treatment (T1) (after 10 rehabilitation sessions over a 5-week period), and at the 12-week follow-up (T2). Results. The PS-group experienced a statistically significant improvement versus the CG in FAS and HAQ scores. Good efficacy with respect to pain and function in the PE-group compared with the CG in terms of FAS, HAQ, and FIQ scores was observed. The adherence ratio was 86% for the PE-group and CG and 90% for the PS-group. Conclusions. According to the results, the PS are as promising as the physical exercises, since results were similar.

Tactile and proprioceptive sensory stimulation modifies estimation of walking distance but not upright gait stability: a pilot study

[Purpose] Recently, there has been growing interest in the somatosensory system, but little data exist on the interaction between dynamic postural control and the somatosensory system. The purpose of this study was to determine whether a training program, based on tactile and proprioceptive sensory stimulation of the trunk with the use of perceptual surfaces, improved the estimation of walking distance by healthy subjects, the ability to walk toward a memorized distance without vision, and whether it increases upright gait stability. [Subjects and Methods] Ten healthy subjects with a mean age of 31.9 ± 2.5 years were enrolled and participated in 10 daily sessions of perceptive training using perceptual surfaces, for 45 minutes each session. An experimental indoor test measured the subjects' ability to perceive walking distances to a memorized target in an indoor environment. [Results] After treatment, the distances that were traversed were closer to the target than before treatment. Trunk acceleration did not differ significantly between pre- and post-training and did not increase significantly after training. [Conclusion] Treatment with perceptual surfaces stimulating the trunk midline improves the estimation of walking distance and modifies proprioceptive gait patterns, allowing various corrective strategies to be implemented during ambulation.

Spinopelvic balance and body image perception in Parkinson's disease: analysis of correlation

PURPOSE

The purpose of this study was to describe the association between body image perception and sagittal balance (SB) parameters in Parkinson's Disease (PD) patients.

METHODS

77 consecutive PD patients were included: 44 males, 33 females; 68.9 ± 6.8 years; 5.3 ± 3.8 years from diagnosis (YFD); Hoehn Yahr (HY) 2.0 ± 0.8, Unified Parkinson's Disease rating Score-Motor section (UPDRS-M) 11.8 ± 9.3. Spinopelvic angles and SB were radiographically assessed. Body image perception was assessed through Trunk appearance scale (TAPS) and Stunkard Figure rating scale for BMI. Beck Depression Inventory (BDI) was used to evaluate depressive mood.

RESULTS

We detected 32 (41.5 % of cohort) Parkinson Disease patients with scoliosis ≥15° Cobb. The mean calculated BMI was 27.1 ± 3.9 kg/m(2). According to the Figure Rating Scale, the perceived BMI averaged 27.2 ± 4.5 kg/m(2), while the mean desired BMI was 24.4 ± 2.7 kg/m(2), TAPS scored 3.4 ± 0.9 points, while BDI 12.3 ± 7.9 points. TAPS had a weak negative correlation with the duration of disease (r = -0.25, p < 0.05) and a correlation with H&Y score (r = 0.28, p < 0.05). Sacral Slope was weakly correlated to the calculated BMI (r = -0.24, p < 0.05). SSA and SPA had a negative correlation with the TAPS mean score (respectively, r = -0.36 and -0.24, p < 0.05). BDI presented a weak correlation with TAPS (r = 0.27, p < 0.05) but not with self esteemed BMI values (p > 0.05).

CONCLUSIONS

Spinopelvic parameters and depression had a specific and concurrent influence on trunk deformity perception but not on BMI self-esteem.
