Fear of Falling in Muscular Dystrophy

to assess motor functionality. It is a scale consisting of 17 items that assess the performance of different functional skills, graded on a scale from 0 (unable), 1 (completed independently but with modifications), to 2 (completed without compensation. NSAA measures functional motor abilities in ambulant children with Duchenne Muscular Dystrophy (DMD). It is usually used to monitor the progression of the disease and treatment effects (Scott et al., 2012).

to assess postural abilities. During the posturographic examinations, the amount of body oscillation is determined by recording the Centre of Pressure (COP) displacements over a period (Verbecque et al., 2016). Utilizing a posturographic platform for quantitative analysis offers enhanced accuracy and a deeper understanding of the patient's functional status. TYMO® device, a portable posturography platform, is employed to measure the tilts of the body's center of mass and track the outcomes of the rehabilitation process. This tool facilitates an objective, straightforward, and quantitative evaluation of the patient's functional status. The evaluative exercises offer various tests, including weight distribution assessment in force or percentage, balance assessment, equilibrium control assessment, and step counting.

to assess walking functionality. The amount of walking will be measured one week before and one week after the rehabilitation intervention using a pedometer. To ensure maximum accuracy, participants will wear a watch all day except at night to track the number of steps.

to assess the number of falls in the previous 3 months and any related consequences. During the first assessment, patients will be asked about the presence and number of falls in the last 3 months and the consequences of these falls.

to assess the level of disability. The Barthel Index, a scale used to assess the level of disability, consists of 10 items related to common daily activities (feeding, dressing/grooming, personal hygiene, bathing/showering, bladder continence, transferring from chair to bed, using the toilet, mobility/ambulation on level ground, climbing or descending stairs), investigating the degree of patient dependence/independence. The score for each item can be 0 (=dependent), 5 (=requires assistance), or 10 (=independent), with a maximum possible score of 100. A score below 100 indicates the presence of dependence (Mahoney et al.,1965).

to assess cognitive global status. It is a screening tool for overall cognitive functioning consisting of 12 subtests exploring the following cognitive domains: memory (scores 0-5), visuospatial abilities (score 0-4), executive functions (score 0-4), attention, concentration, and working memory (score 0-6), language (score 0-6), spatial and temporal orientation (score 0-6). The total score ranges from 0 to 30, with higher scores indicating better cognitive functioning (Santangelo et al., 2015).

to assess psychomotor speed, attentional set-shifting, and visual-spatial search speed. It is composed of two parts. In Part A, which investigates selective attention, the participant must connect 25 circled numbers (distributed in a standardized random layout) in ascending order. In Part B, which investigates attentional set-shifting, the participant must alternately connect circled numbers from 1 to 13 and circled letters from A to N (e.g., 1-A-2-B-3-C). There is also a third index consisting of the difference between the scores obtained in Part A and Part B, indicating psychomotor and visual-spatial search speed. The faster and more accurate the patient is, the more their performance will be within the norm (Siciliano et al., 2019).

to assess visuospatial fluency by measuring the ability and speed to initiate a mental programming task and self-monitoring and visuospatial fluency. The result is based on the number of correct and unique drawings generated in 3 minutes (UDs) and the total number of drawings created according to a strategy (CSs) (Cattelani et al., 2011).

to assess depressive symptoms. It is a self-administered instrument that assesses the severity of depression in adult subjects. It consists of 21 items and yields a total score; a higher score indicates greater depressive symptoms (range 0-63). The scale includes different cut-offs depending on the severity of the symptoms: 0-13 mild depression, 14-19 moderate depression, 20-28 moderate depression, 29-63 severe depression (Montano, Flebus, 2006).

to assess anxiety symptoms. The questionnaire consists of 40 items to which the subject must respond in terms of perceived intensity on a Likert scale from 1 to 4 (higher scores indicating greater anxiety symptoms). The items are grouped into two scales. The first one investigates state anxiety, conceived as a particular experience of helplessness or insecurity in the face of perceived harm that can lead to worry or escape and avoidance. The second investigates trait anxiety, the tendency to perceive stressful situations as dangerous and threatening and to respond to various situations with varying intensity (Pedrabissi, Santinello, 1989).

to define personality traits. It is a sheet for observing and evaluating individual and organizational behaviors and social attitudes toward others. It can be used in any situation requiring hetero or self-assessment activities. The BFO is grounded in the theoretical framework of the psycholinguistic approach, using terms that are understandable even to non-psychologists. It consists of 40 pairs of opposite adjectives (8 for each Big Five: Extraversion-Introversion, Agreeableness-Disagreeableness, Conscientiousness-Negligence, Neuroticism-Emotional Stability, Openness-Closedness of Mind) selected from the Italian language vocabulary to be evaluated on a 7-point Likert scale (Caprara et al., 1994).

to assess patient's quality of life. It is a popular instrument for evaluating Health-Related. The SF-36 measures eight scales: physical functioning (PF), role physical (RP), bodily pain (BP), general health (GH), vitality (VT), social functioning (SF), role emotional (RE), and mental health (MH). Component analyses showed two distinct concepts measured by the SF-36: a physical dimension, represented by the Physical Component Summary (PCS), and a mental dimension, represented by the Mental Component Summary (MCS). All scales contribute in different proportions to scoring PCS and MCS measures (Apolone \& Mosconi, 1998).
