Brief summary
Postural abnormalities (PA) are drug refractory complications in patients with Parkinson's disease (PD) leading to pain, imbalance, gait disorders and fall-related injuries. It ultimately affects the quality of life and the hospitalisation risk. the literature on treatment outcomes is scant. Rehabilitation is the cornerstone in the management of PD patients, especially for drug-refractory complications. However, the current efforts are only partially able to resolve PA in PD. Despite differences in methodologies, the few rehabilitative studies support the benefits of trunk rehabilitation in PD with PA. Priorities for future research include well-design rehabilitation studies on a large population. The early detection and early rehabilitation of PA might avoid fixed irreversible deformities and reduce the complications that can accompany them. It ultimately might improve the quality of life, reduce the risk of fall-related injuries and hospitalisation rate. A single-blind single-blind Randomised Controlled Trial (RCT) will evaluate the effects of trunk rehabilitation on PA severity, function and disability in outpatients with Parkinson Disease and postural abnormalities.
Detailed description
This RCT with two parallel group will be conducted according to the tenets of the Declaration of Helsinki, the guidelines for Good Clinical Practice, and the Consolidated Standards of Reporting Trials (CONSORT). The target population will be patients with Parkinson Disease who attend to the Neurorehabilitation Unit (AOUI Verona) and the Unità Operativa Complessa (UOC) Neurology ward (AOUI Verona) where they will be assessed for eligibility. Who satisfied inclusion and exclusion criteria were randomly allocated in one of two groups, the experimental group and control group. Each patient will undergo rehabilitation. Before the start of the study authors designed the experimental and the control group protocols. Two physiotherapists, one for each group, carried out the rehabilitation procedures. Patients of both groups received 10 individual sessions (60 min/session, 2 sessions/week, five consecutive weeks). Treatments will be performed in the rehabilitative gym of the G.B. Rossi University Hospital Neurological Rehabilitation Unit. For the statistical analysis, an intention to treat analysis will be used. Descriptive statistics included means, standard deviation and graphs. The Shapiro-Wilk test will be used to test data distribution. Parametric or non-parametric tests will be used for inferential statistics, accordingly. The T-Test for unpaired data (or the Mann-Whitney test) will be used for testing between-group differences at T0 and T1. For this purpose, the changes of the score (Δ) between T0-T1 will be computed. The T-Test for paired data (or Wilcoxon signed rank tests) will be used to compare within-group changes over time. The level of significance was set p\<0.05. Software statistics SPSS 20.0 (IBM Statistical Package for Social Science (SPSS) Statistics for Windows, Version 20.0, Armonk, NY, USA).
Interventions
PROCEDUREExperimental group
Active self-correction exercises (20 minutes) to achieve the best possible trunk alignment the patient can achieve in the three-dimensional planes using visual, proprioceptive and EMG feedbacks. Passive and active trunk stabilization exercises (20 minutes) to improve trunk biomechanical constraint Functional tasks (20 minutes) defined as functional exercises to train the automatic response to maintain the best alignment through the broadest possible range of challenging activities (Romano2015).
PROCEDUREControl group
Training consisted of passive and active trunk mobilization (10 minutes) followed by muscle stretching, and strengthening exercises, and gait training (50 minutes)(Bartolo et. al., 2010).

Masking description
Outcome assessor will be blinded. Patients will be specifically asked not to discuss their treatment during assessments. Examiner will be requested to inform the research coordinator if he will discover to which group a patient belonged, and they will periodically be questioned by the coordinator about this.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Changes in the degrees of trunk deviation in the sagittal and coronal plane. | Pre-treatment, after 5 weeks, at 1 month-follow-up and 4-month follow-up | Changes in the degree of trunk deviation in the sagittal and coronal plane will be assessed using a wall goniometer in standing position. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Changes in the Percentage Difference of Sway (PDS) | Pre-treatment, after 5 weeks, at 1 month-follow-up and 4-month follow-up | The PDS computed for sway velocity in the eyes open (eo) and eyes closed (ec) conditions. A ratio close to zero or negative indicates that the magnitude of body sway is similar or smaller in the ec than in the eo condition . On the contrary, positive values reflect a larger sway in the ec than in the eo condition. |
| Changes in the Unified Parkinson's Disease Rating Scale (UPDRS) | Pre-treatment, after 5 weeks, at 1 month-follow-up and 4-month follow-up | It is a comprehensive assessment designed to monitor the burden and the extent of Parkinson Disease across the longitudinal disease course and provides a clinical end-point in clinical trials. It consists of four sections with a total summed score. Each item have 5 response options (0=normal; 4=severe symptoms/signs). The higher= greater impact of PD symptoms. The Unified Parkinson's Disease Rating Scale - part III (UPDRS III) subscale will be used to measure changes in the motor disability (score range, 0-33; the higher=worse symptoms). |
| Changes in the Parkinson's Disease Questionnaire (PDQ-8) | Pre-treatment, after 5 weeks, at 1 month-follow-up and 4-month follow-up | The PDQ-8 contains eight of the original 39 items of the PDQ-39; one item selected from each of the 8 scales (mobility, activities of daily living, emotional well-being, stigma, social support, cognitions, communications and bodily discomfort). It provides a reliable measure of overall health status and is ideal for studies in which a shorter questionnaire is preferred. Each question is scored from 0-4 points and the scores are summed. the summed scores are then divided by total possible score and given as a percentage score out of 100 (Score range, 32-100; the higher worse health status) |
| Changes in Gait speed (cm/sec) | Pre-treatment, after 5 weeks, at 1 month-follow-up and 4-month follow-up | Changes in gait speed will be assessed using the Gait Rite System. It is a computerized walkway providing temporal spatial gait analysis. |
| Changes in the Mini Balance Evaluation System test (Mini BESTest) | Pre-treatment, after 5 weeks, at 1 month-follow-up and 4-month follow-up | It is a clinical balance assessment tool to target and identify 4 different balance control systems (anticipatory postural adjustments, reactive postural control, sensory orientation, dynamic gait) so that specific rehabilitation approaches can be designed. It is a 14-item test scored on a 3-level ordinal scale (0-2). Total score range 0-32; the higher= better performance. |
| Changes in the Numeric Pain Rating Scale (NPRS) | Pre-treatment, after 5 weeks, at 1 month-follow-up and 4-month follow-up | A numeric rating scale to measure the amount of pain that a patient feels ranges across a continuum from none (0) to an extreme amount of pain (10). Total score range 0-10; the higher= worse performance. |
| The number of falls | Pre-treatment, after 5 weeks, at 1 month-follow-up and 4-month follow-up | Number of falls occured in the previous month. |
