Sponsored by IRCCS Eugenio Medea · Not applicable, Interventional, and Treatment
The primary objective is to evaluate the potential effectiveness of an individualized intensive rehabilitation intervention using the "Prokin 252" stabilometric platform in the treatment of adolescent and adult patients with Friedreich's Ataxia. The secondary objective is to assess the retention of the rehabilitation treatment effects over time.
Enrolled patients will be randomized and assigned to one of two treatment groups for four weeks. Three assessments will be conducted for each patient: one before treatment (T0), one at the end of treatment (T1), and a follow-up assessment 90 days after T1 via telemedicine (T2).

In recent years, there has been increasing interest in the scientific literature on degenerative diseases such as ataxic syndromes. Friedreich's Ataxia is one of the most common forms of hereditary ataxia. It is defined as a multisystemic neurodegenerative disorder with an autosomal recessive inheritance pattern, presenting both neurological and non-neurological clinical manifestations. The disease results from a mutation in the X25 gene on chromosome 9, characterized by an excessive repetition of the GAA trinucleotide, which leads to a reduction and malfunction of frataxin. Friedreich's Ataxia typically manifests in the first or second decade of life, with a significant functional impact and progressive disability. Often, initial symptoms are characterized by severe balance and coordination impairments, which not only affect functional independence but also patients' quality of life.
Currently, therapeutic options are very limited. Omaveloxolone is the first and only drug approved in 2023 by the Food and Drug Administration and The European Medicines Agency for adults and adolescents aged ≥16 with Friedreich's Ataxia. It has been shown to improve the score on the Modified Friedreich's Ataxia Rating Scale after chronic treatment. Rehabilitation is defined by the World Health Organization as a set of interventions designed to reduce disability and optimize functioning in individuals interacting with their environment. Current literature suggests that rehabilitation plays a central role in the treatment of Friedreich's Ataxia. Impairments and limitations associated with Friedreich's Ataxia can be addressed through rehabilitative procedures that, although they do not affect disease progression, may significantly improve the patient's functionality. Several studies indicated that the use of technological aids in neurorehabilitation leads to improvements in various conditions. Technological aids offer several advantages over traditional rehabilitation by significantly contributing to motor learning and brain plasticity, both of which are key to improving motor recovery. These aids can be easily tailored to the specific needs of each patient. Technology-based rehabilitation platforms can adjust the difficulty level and type of exercises according to the patient's progress, ensuring a personalized approach. The use of technologies such as virtual reality and interactive games makes rehabilitation more engaging and enjoyable. This increases patients' motivation to actively participate in rehabilitation sessions, improving adherence to treatment. Technologies can provide real-time feedback on patient performance, enabling immediate adjustments and enhancing motor learning. This type of feedback is crucial for improving body awareness and movement precision. Additionally, technologies can integrate visual, auditory, and tactile stimuli, which can enhance learning and brain plasticity.
One technological aid used in rehabilitation is the stabilometric platform. This consists of a platform equipped with sensors that record the oscillations of the body's center of gravity while the patient stands on it. These data can be used to analyze postural stability, detect balance problems, and monitor progress in rehabilitation programs. It is often used in fields such as physiotherapy, sports, and biomechanical research. In recent years, it has also been used as a rehabilitative tool to improve balance, coordination, and proprioception, including in the neurological field. Integrating the stabilometric platform into rehabilitation programs offers a more comprehensive and targeted approach to addressing balance and postural stability issues. Several studies have compared conventional rehabilitation with combined treatments involving the stabilometric platform. Results indicate that conventional balance training can improve balance function in patients, but when combined with visual feedback balance training, the improvements are more significant. In the literature, the use of the stabilometric platform combined with traditional physiotherapy has shown considerable effectiveness in resolving balance deficits in patients with various neurological conditions, though this has not been demonstrated in . In the literature on Friedreich's Ataxia, several studies have used this tool for assessment purposes. Balance parameters obtained using the stabilometric platform have shown a significant increase over time in patients with Friedreich's Ataxia, indicating impaired postural stability and balance while standing. These measures are significantly correlated with performance scores on the Friedreich's Ataxia Rating Scale, particularly with the Friedreich's Ataxia Rating Scale subscale on Upright Stability. However, there are no specific studies regarding the application of this device as a rehabilitative tool in Friedreich's Ataxia.
According to the existing literature, the investigators propose an open-label, monocentric, randomized pilot study to compare the effectiveness of a conventional rehabilitation program combined with training on the stabilometric platform (Group A) versus conventional rehabilitation alone (Group B) in improving balance reactions specifically in patients with mild to moderate Friedreich's Ataxia. The investigators will use the Prokin 252 system on the Tecnobody stabilometric platform. Enrolled patients will be randomly assigned to one of the two treatment groups for four weeks. Three assessments will be conducted for each patient: one before treatment (T0), one at the end of treatment (T1), and a follow-up assessment 90 days after T1 via telemedicine (T2). At T0 and T1, assessments will include tests and scales that measure the patient's overall functioning, commonly used in clinical practice, such as the Modified Friedreich's Ataxia Rating Scale, Scale for Assessment and Rating of Ataxia, 6-Minute Walk Test, Timed Up and Go, Berg Balance Scale, and Functional Reach Test. Additionally, using the stabilometric platform, patients will perform static stability and limits of stability tests while standing. At T2, patients will be reassessed via telemedicine with only the Modified Friedreich's Ataxia Rating Scale administered and Scale for Assessment and Rating of Ataxia. Changes in scores obtained on scales and on stabilometric platform parameters will serve as the evaluation criteria for the potential effectiveness of the treatment, also compared to the outcomes of standard physiotherapy treatment.

Exclusion Criteria:
Balance training including both conventional rehabilitation (24 sessions) and training over a stabilometric platform (20 sessions).
Behavioral: Balance training over stabilometric platform · Behavioral: Balance training by means of conventional rehabilitation
Balance training including only conventional rehabilitation (44 sessions).
Behavioral: Balance training by means of conventional rehabilitation
The treatment using the stabilometric platform (a total of 20 sessions) generally includes an initial phase (approximately 5 minutes) of training and warm-up in "monitor" mode, during which the patient becomes familiar with the equipment. The patient then moves on to "training library" mode, which includes the following subcategories: (1) Stabilometric tracings in both static and dynamic phases (10 minutes); (2) Dexterity exercises in both static and dynamic phases (10 minutes); (3) Imbalance exercises in both static and dynamic phases (10 minutes). The goal during this phase is to increase the patient's stability limits and provoke balance reactions through load shifts in all directions. The session concludes with 10 minutes of TecnoBody Exergames, which help to automate the functions learned within a more complex activity.
Also known as: PROKIN - PK252
Conventional rehabilitation to improve balance includes an initial phase of tissue mobilization, particularly of the foot structures (approximately 5 minutes per foot), in order to prepare them for the subsequent activation phase. This is followed by a phase focused on activating the anti-gravity muscles and aligning the trunk within the chosen setting (10 minutes). The treatment continues with balance training, both static and dynamic, load transfers, and dual-task exercises using external references (15 minutes). The session concludes with functional exercises relevant to the patient's daily life context (10 minutes).

Score on the subscale 'Section E. Upright stability' of the modified Friedreich Ataxia Rating Scale.
The outcome evaluates balance performance while sitting, standing, and walking. Lower scores indicate better balance performance, higher scores indicate more severe balance impairment.
Time frame: Enrolment (T0), end of treatment at four weeks (T1), follow-up at 12 weeks after T1 (T2).
Modified Friedreich's Ataxia Rating Scale (mFARS)
Clinical assessment of severity for neurological deficits, specifically designed for patients affected by Friedreich's Ataxia. The maximum score is 93, with higher scores indicating more severe neurological deficit. mFARS includes four subscales, evaluating 'bulbar' function (cough and speech), upper limb coordination, lower limb coordination, and upright stability (sitting, standing, walking).
Time frame: Enrolment (T0), end of treatment at four weeks (T1), follow-up at 12 weeks after T1 (T2).
Scale for Assessment and Rating for Ataxia (SARA).
SARA is a semi-quantitative clinical assessment of cerebellar ataxia. It is composed by eight items: gait, stance, sitting, speech disturbance, finger chase, nose-finger test, fast alternating hand movements, heel shin slide. The final score ranges from zero (absence of ataxia) to 40 (severe ataxia).
Time frame: Enrolment (T0), end of treatment at four weeks (T1), follow-up at 12 weeks after T1 (T2)..
Six minutes walking test (6MWT).
6MWT is a clinical assessment of gait endurance, by measuring the distance covered (metres) while walking on a straight even path (30 meters) for six minutes. According to original instructions, the patient is asked to walk along the path as fast as possible, taking turns at the edges of the path. Patients are allowed to walk autonomously or with assistive devices and to rest by standing.
Time frame: Enrolment (T0), end of treatment at four weeks (T1).
Timed Up and Go test (TUG).
TUG evaluates mobility, balance, gait competence and fall risk. The test measures the time taken (seconds) to stand up from a standard armchair, walk three metres, turn and come back sitting. The patient cannot receive physical assistance during the test but is allowed to use assistive devices.
Time frame: Enrolment (T0), end of treatment at four weeks (T1).
Berg balance scale (BBS).
BBS is a clinical assessment of sitting balance, standing balance, and transfers. It's composed by 14 items, each item ranging from 0 (unable to complete the task) to 4 (able to complete the task according to time and instructions given). A higher score indicates better balance, with a score ≤43,5 predictive of fall risks.
Time frame: Enrolment (T0), end of treatment at four weeks (T1).
Functional Reach Test (FRT).
FRT evaluates dynamic balance while standing. Patient is asked to stand with one shoulder flexed at 90 degrees and the hand making a fist, and then to bend forward up to the limit of balance, right before taking a step to prevent falling. A horizontal ruler taped on the wall is used to measure the difference in position of the head of the third metacarpal bone from starting to end position. Patients are not allowed to touch the wall or rotate the trunk while bending forward.
Time frame: Enrolment (T0), end of treatment at four weeks (T1).
Stabilometric platform.
With the patient standing over a stabilometric platform, two kinematic assessments will be performed: (1) static stance, by standing for 30 seconds with eyes open and 30 seconds with eyes closed; (2) limits of stability, by bending with the body in different direction, displacing the centre of mass towards anterior, posterior, and lateral targets projected on a screen in front of the patient.
Time frame: Enrolment (T0), end of treatment at four weeks (T1).
