Effects of physiotherapy and home-based training in parkinsonian syndromes: protocol for a randomised controlled trial (MobilityAPP).

INTRODUCTION: Gait and mobility impairment are pivotal signs of parkinsonism, and they are particularly severe in atypical parkinsonian disorders including multiple system atrophy (MSA) and progressive supranuclear palsy (PSP). A pilot study demonstrated a significant improvement of gait in patients with MSA of parkinsonian type (MSA-P) after physiotherapy and matching home-based exercise, as reflected by sensor-based gait parameters. In this study, we aim to investigate whether a gait-focused physiotherapy (GPT) and matching home-based exercise lead to a greater improvement of gait performance compared with a standard physiotherapy/home-based exercise programme (standard physiotherapy, SPT). METHODS AND ANALYSIS: This protocol was deployed to evaluate the effects of a GPT versus an active control undergoing SPT and matching home-based exercise with regard to laboratory gait parameters, physical activity measures and clinical scales in patients with Parkinson's disease (PD), MSA-P and PSP. The primary outcomes of the trial are sensor-based laboratory gait parameters, while the secondary outcome measures comprise real-world derived parameters, clinical rating scales and patient questionnaires. We aim to enrol 48 patients per disease group into this double-blind, randomised-controlled trial. The study starts with a 1 week wearable sensor-based monitoring of physical activity. After randomisation, patients undergo a 2 week daily inpatient physiotherapy, followed by 5 week matching unsupervised home-based training. A 1 week physical activity monitoring is repeated during the last week of intervention. ETHICS AND DISSEMINATION: This study, registered as 'Mobility in Atypical Parkinsonism: a Trial of Physiotherapy (Mobility_APP)' at clinicaltrials.gov (NCT04608604), received ethics approval by local committees of the involved centres. The patient's recruitment takes place at the Movement Disorders Units of Innsbruck (Austria), Erlangen (Germany), Lausanne (Switzerland), Luxembourg (Luxembourg) and Bolzano (Italy). The data resulting from this project will be submitted to peer-reviewed journals, presented at international congresses and made publicly available at the end of the trial. TRIAL REGISTRATION NUMBER: NCT04608604.

Training high level balance and stepping responses in atypical progressive supranuclear palsy: a case report.

BACKGROUND: Progressive supranuclear palsy (PSP) is a neurodegenerative condition, typically presenting with, but not limited to, impairments of postural instability, gait, and gaze stability. PURPOSE: This case report describes the multifactorial assessment and rehabilitation of a patient with atypical PSP who has significant gaze deficits, asymmetrical stepping responses, trunk rigidity, and reduced posterior excursion on limits of stability. CASE DESCRIPTION: Evaluation utilized computerized gait and balance assessments, foot clearance analysis, a squat test, and a timed stepping test. The intervention included boxing, stepping tasks, and treadmill training each with eye movement challenges. A total of 15 hours of physical therapy was provided; 1 hour, 2 times a week. OUTCOMES: Post-intervention improvements were noted subjectively, on eye-body coordination, and objectively, on limits of stability, foot clearance, and task performance (squats, timed stepping). Follow-up demonstrated some decline from posttest results; however, patient-reported adherence to the program was less than recommended. CONCLUSION: A multifactorial rehabilitation program can improve balance, eye-body coordination, and strength in a high functioning patient with atypical PSP. Longitudinal randomized controlled studies are suggested to further investigate this interventional approach in high functioning individuals diagnosed with atypical PSP.

The Role of Rehabilitation in Patients With Progressive Supranuclear Palsy: A Narrative Review.

Progressive supranuclear palsy (PSP) is a progressive neurodegenerative disorder caused by the deposition of abnormal proteins in neurons of the basal ganglia that limit motor ability, resulting in disability and reduced quality of life. So far, no pharmacologic therapy has been developed, and the treatment remains symptomatic. The aim of the present study is to perform a systematic investigation of the literature, and to determine the types and effects of rehabilitative interventions used for PSP. A search of all studies was conducted in MEDLINE/PubMed, the Cochrane Central Register of Controlled Trials, CINAHL, and EMBASE. Twelve studies were identified, including 6 case reports, 3 case series, one case-control study, one quasi-randomized trial (i.e. not truly random) with crossover design, and one randomized controlled trial, with 88 patients investigated overall. Rehabilitative interventions varied in type, number, frequency, and duration of sessions. The most commonly used clinical measures were the Progressive Supranuclear Palsy Rating Scale (PSPRS) and Unified Parkinson's Disease Rating Scale (UPDRS). Physical exercises were the main rehabilitative strategy but were associated with other interventions and rehabilitative devices, in particular treadmill and robot-assisted gait training. All studies showed an improvement in balance and gait impairment with a reduction of falls after rehabilitation treatment. Because of poor methodological quality and the variety of rehabilitative approaches including different and variable strategies, there was insufficient evidence of the effectiveness of any specific rehabilitation intervention in PSP. Despite this finding, rehabilitation might improve balance and gait, thereby reducing falls in PSP patients. LEVEL OF EVIDENCE: IV.

Rehabilitation in progressive supranuclear palsy: Effectiveness of two multidisciplinary treatments.

BACKGROUND: to date, there are no medical or surgical treatments for progressive supranuclear palsy (PSP). It is possible to speculate that patients with PSP could benefit from rehabilitative treatments designed for Parkinson's disease, including the use of robot-assisted walking training. OBJECTIVE: to evaluate whether the use of the robotic device Lokomat® is superior in PSP patients to the use of treadmill with visual cues and auditory feedbacks (treadmill-plus) in the context of an aerobic, multidisciplinary, intensive, motor-cognitive and goal-based rehabilitation treatment (MIRT) conceived for Parkinsonian patients. METHODS: we enrolled twenty-four PSP patients. Twelve subjects underwent a 4-week MIRT exploiting the use of the treadmill-plus (MIRT group). Twelve subjects underwent the same treatment, but replacing the treadmill-plus with Lokomat® (MIRT-Lokomat group). Subjects were evaluated with clinical and functional scales at admission and discharge. The primary outcomes were the total PSP Rating Scale (PSPRS) score and its "limb" and "gait" sub-scores. Secondary outcomes were Berg Balance Scale (BBS), Six Minutes Walking test (6MWT) and the number of falls. RESULTS: total PSPRS, PSPRS-gait sub-score, BBS, 6MWT and number of falls improved significantly in both groups (p ≤ 0.003 all, except 6MWT, p = 0.032 and p = 0.018 in MIRT-Lokomat and MIRT group respectively). The PSPRS-limb sub-score improved significantly only in the MIRT group (p = 0.002). A significant difference between groups was observed only for total PSPRS, indicating a slightly better improvement for patients in the MIRT group (p = 0.047). No differences between groups were revealed for the other outcomes, indicating that the effect of rehabilitation was similar in both groups. CONCLUSIONS: Lokomat® training, in comparison with treadmill-plus training, does not provide further benefits in PSP patients undergoing MIRT. Our findings suggest the usefulness of an aerobic, multidisciplinary, intensive, motor-cognitive and goal-based approach for the rehabilitation of patients suffering from such a complex disease as PSP. TRIAL REGISTRATION: This trial was registered on ClinicalTrials.gov, NCT02109393.

Combined rehabilitation program for postural instability in progressive supranuclear palsy.

BACKGROUND: Progressive supranuclear palsy (PSP) is an atypical parkinsonism clinically characterized by prominent axial extrapyramidal motor symptoms with frequent falls. The clinical response to L-dopa is poor and there is strong need for alternative treatment strategies. METHODS: We tested the efficacy of a rehabilitative program combining a dynamic antigravity postural system (SPAD) and a vibration sound system (ViSS) on postural instability of 10 patients affected by PSP. The patients underwent SPAD and VISS treatments with a 3 sessions/week schedule for 2 months. Patients were clinically examined at baseline, every week during the 2-months treatment, and at 1 month after the end of treatment for the following parameters: baropodometry static, baropodometry dynamic and stabilometry. PSP rating scale and PD36 quality of life scale were also administered. RESULTS: The combined rehabilitative program produced improvement of all the parameters explored (p = 0.01-0.05) at the end of treatment as compared to baseline. Baropodometric dynamics improvement lasted until the end of follow-up. CONCLUSION: Our results suggest that a specific rehabilitation program could improve postural instability in PSP patients. A more continuous treatment protocol would allow stabilizations of results.

Clinical and single-photon emission computed tomography study of pure akinesia with freezing of gait.

The clinical syndrome of pure akinesia (PA) is considered the third phenotype of progressive supranuclear palsy (PSP), and is characterized by freezing of gait and prominent speech disturbance without rigidity or tremor. It is frequently considered one of the dopamine resistant motor syndromes, and its pathophysiology remains unclear. We report a patient followed in the Department of Neurology of Razi Hospital, Tunisia, with PA with gait freezing (PAGF) with a frontal hypoperfusion on single photon emission CT and non-responsive dopa therapy. We discuss the clinical features of PAGF and efficiency of treatment options.

[Somatoform disorder or neurological syndrome? Complex mental and movement disorder and autonomic dysfunction in a 65-year-old patient - Case 1/2011]. / Somatoforme Störung oder neurologisches Syndrom? Komplexe psychische, vegetative und motorische Störungen bei einer 65-jährigen Patientin - Fall 1/2011.

HISTORY AND ADMISSION FINDINGS: A 65-year-old female patient presented with increasing vertigo, tendency to fall, dry cough and, in addition, numerous psychic and somatic symptoms since 6 years. Former diagnostic attempts did not yield clarifying results. In part, the patient had not followed up on former recommendations for further diagnostic procedures. With a suspected somatization disorder the patient was admitted to the Department of Psychosomatic Medicine. INVESTIGATIONS: The neurological examination at admission revealed vertical oculomotor palsy and tendency to fall backwards indicating an affection of the brain stem. A magnetic resonance imaging of the head showed atrophy of the mesencephalon. DIAGNOSIS AND TREATMENT: In light of these findings the patient was diagnosed Steele-Richardson-Olszewksi syndrome. The therapy which comprises training measures and medication with a cholinesterase inhibitor aims to retain neuropsychological and motional abilities. Besides, psychotherapy is offered alongside to help the patient to cope with the disease. CONCLUSIONS: Treating patients with somatic and psychological symptoms calls for careful anamnestic exploration and clinical examination. Psychological alterations following neurological affection of the brain can imitate somatization disorder.

Improvement of balance after audio-biofeedback. A 6-week intervention study in patients with progressive supranuclear palsy.

Progressive supranuclear palsy (PSP) is a neurodegenerative disease with no sufficient treatment options to date. The most devastating symptom is the loss of balance with consecutive falls. Based on the observation that postural control improved in patients with vestibular dysfunction after audio-biofeedback training, we tested the effects of this training in PSP patients. Eight PSP patients were included into an uncontrolled 6-week intervention trial. The focus of the training was the improvement of posture and dynamic balance by using audio-biofeedback. The device was well accepted. No adverse events occurred. A significant improvement in the Berg Balance Scale was observed (T2 vs. T1, p=0.016), which remained significant at the 4-week follow-up (T3 vs. T1, p=0.008). Significant improvement of the Parkinson's disease questionnaire was demonstrated. No significant changes were found in the Timed Up-and-Go Test, the Five Chair Rise Test, and in specific clinical scales. To our knowledge, the present study is the first to demonstrate that audio-biofeedback training with PSP patients is associated with improvements of balance and psychosocial aspects.

Balance and eye movement training to improve gait in people with progressive supranuclear palsy: quasi-randomized clinical trial.

BACKGROUND AND PURPOSE: Although vertical gaze palsy and gait instability are cardinal features of progressive supranuclear palsy (PSP), little research has been done to address oculomotor and gait rehabilitation for PSP. The purpose of this study was to compare the benefits of a program of balance training complemented with eye movement and visual awareness training versus balance training alone to rehabilitate gait in people with PSP. PARTICIPANTS: Nineteen people moderately affected by the disease were assigned to either a treatment group (balance plus eye movement exercises, n=10) or a comparison group (balance exercises only, n=9) in a quasi-random fashion. METHODS: The baseline characteristics assessed were diagnosis (possible versus probable), sex, age, time of symptom onset, dementia, and severity of symptoms. Within-group, between-group, and effect size analyses were performed on kinematic gait parameters (stance time, swing time, and step length) and clinical tests (8-ft [2.4-m] walk test and Timed "Up & Go" Test). RESULTS: The within-group analysis revealed significant improvements in stance time and walking speed for the treatment group, whereas the comparison group showed improvements in step length only. Moderate to large effects of the intervention were observed for the treatment group, and small effects were observed for the comparison group. The between-group analysis did not reveal significant changes for either group. DISCUSSION AND CONCLUSION: These preliminary findings support the use of eye movement exercises as a complementary therapy for balance training in the rehabilitation of gait in people with PSP and moderate impairments. Additional studies powered at a higher level are needed to confirm these results.

Bilateral internuclear ophthalmoplegia in progressive supranuclear palsy with an overriding oculocephalic maneuver.

We present a patient with progressive supranuclear palsy (PSP) who had a bilateral internuclear ophthalmoplegia (INO) that could be fully overcome by the oculocephalic maneuver. In addition to being an unusual finding in the clinical setting of PSP, this phenomenon has interesting implications for the functional control of conjugate horizontal gaze.

Supported treadmill training for gait and balance in a patient with progressive supranuclear palsy.

BACKGROUND AND PURPOSE: Impaired balance, gait disturbances, and frequent falls are common problems in people with progressive supranuclear palsy (PSP). This case report describes the use of a modified body weight support treadmill training program to reduce falls and improve the balance and gait of a patient with PSP. CASE DESCRIPTION: The patient was a 62-year-old man diagnosed with PSP. His major problems were impaired balance and frequent, abrupt falls. METHODS: Physical therapy included walk training, balance perturbation, and step training using body weight support with a treadmill. Training sessions lasted 11/2 hours and occurred 3 days a week for 8 weeks. Fall incidence, balance, and gait were assessed before, during, and after the program. OUTCOMES: The patient reported fewer falls during and after training. Balance and gait improved after training. DISCUSSION: This case report is the first to report fall reduction, improved gait, and improved balance following physical therapy for a person with PSP.

Progressive supranuclear palsy: clinical presentation and rehabilitation of two patients.

Progressive supranuclear palsy (PSP), is an infrequent movement disorder characterized by supranuclear ophthalmoplegia, pseudobulbar palsy, and axial dystonia with frequent and unpredictable falls, usually backward. Median survival from time of diagnosis is two years. When diagnosis is reached, the patients are usually disabled and unable to ambulate independently. No specific rehabilitation protocol has been described for PSP. This article examines our rehabilitation experience with two PSP patients and our management of their frequent and unpredictable falls. The rehabilitation program consisted of a thorough physical evaluation; cognitive and speech evaluation and training; exercises to improve strength and coordination; and static and dynamic balance training. In order to improve safety during ambulation, we provided the patients with a heavy shopping cart or wheelchair that they could grab when in danger of losing their balance. The patients were able to achieve independence in ambulation.
