Non-pharmacological interventional pilot study on the effect of prismatic glasses for the improvement of Pisa syndrome in Parkinson's disease.
The study involves 40 patients, of whom 20 receive active treatment and 20 slow placebo. At the end of the study, all patients receive corrective lenses in compassionate use if the study yields positive results.
In previous cases of patients with Parkinson's disease and Pisa Syndrome, the investigators found a slight improvement in the dystonia of the trunk after the application of prismatic lenses.
The current study provides the involvement of 40 patients with Parkinson's disease, of which twenty treated with permanent prismatic optical correction, and twenty treated with neutral optical correction or with the only optical correction of the refractive basic defects (placebo).
The protocol provides the collection of these data:
- Personal data (date of birth, sex, marital status, profession)
- General history (weight, height, non-neurological and neurological concomitant pathologies, medical conditions that may be associated or predisposing patients to PS, non-antiparkinsonian therapy in progress)
- Specific history for PD (year from the first diagnosis of PD, year of appearance of the first motor symptoms of PD, type and distribution of motor symptoms at the onset)
- Pharmacological history of PD (year of initiation of the first treatment for PD, which drugs (s), antiparkinsonian therapy in progress)
- Neurological Evaluation in ON: UPDRS I, II, III and IV (III: also items-20-26 right and left side), Hoehn-Yahr stage;
- Specific history for PS;
- Detection of some information about the patients' perception of having the torso tilted sideways, direction of inclination, how long it is present, how long it is manifested, conditions in which this inclination is present (standing, sitting, etc.) )
Clinical and kinematic evaluation of PS:
- The amount of dystonia measured in degrees with the patient positioned against the wall against a dedicated protractor. This measurement is photographed.
- Static and dynamic kinematic evaluation (gait analysis) according to the following protocol: 30 seconds stationary in orthostatic position, shoulders to the cameras, about 5 steps forward, stationary in orthostatic position while fixing visual stimulation points placed on the wall, 30 second stationary in an orthostatic position after having covered a section of the corridor in front of the kinematic evaluation room.
complete orthoptic evaluation and prescription of personalized prismatic lenses, randomizing the patient on active or slow-moving placebo lenses with respect to the other experimenters and the patient.
Flowchart of visits:
Screening: the neurologist selects the patient according to the eligibility criteria indicated above and verifies the patient's willingness to participate.
Randomization: the patient undergoes clinical and kinematics evaluation of the PS, orthoptic examination and randomization on active lenses and placebo.
T0: randomization and prescription of lenses T1: check after 1 month from the use of lenses
Patients are recruited at the Parkinson's Center of the IRCCS Neuromed.
