Clinical Trial Summary

The goal of this clinical trial is to investigate the short-term effect of a structured, combined postural control and gaze stabilisation protocol (VIS-REHAB protocol) in a group of vestibular-impaired children of different age categories (3-17 years). The main questions it aims to answer are: - What is the short-term effect of the VIS-REHAB protocol? - What are the most important factors that may influence the effect of and outcome after application of the VIS-REHAB protocol? The participant will undergo both an active rehabilitation program (VIS-REHAB protocol) and a period during which physical therapy is discontinued (CTRL protocol).: - VIS-REHAB protocol: Postural control (static and dynamic postural stability exercises), gaze stability exercises (oculomotor function and VOR-exercises) & general gross motor training with focus on gaze stability and postural control. Researchers will compare the VIS-REHAB protocol with receiving no therapy (CTRL protocol) to evaluate potential enhancements in postural stability, gaze stability, motor performance and quality of life.

Intervention

Behavioral:
• VIS-REHAB protocol
The VIS-REHAB protocol entails two essential components: postural stability (PS) and gaze stability (GS). Within the postural stability component of the VIS-REHAB protocol, there are static and dynamic balance exercises, along with general gross motor activities targeting core stability, agility, and bilateral coordination. The gaze stability part includes exercises enhancing oculomotor function such as smooth pursuit and saccadic movements, as well as VOR-exercises. Additionally, a general gross motor training program emphasises gaze stability by including exercises that improve eye-foot and eye-hand coordination. Furthermore, each session includes counselling and the provision of background information on the exercises.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Static postural stability and sensory integration as assessed by the Bipedal Leg Standing Test	Children will be asked to stand with bare feet on foam as still as possible for 30 seconds, first with eyes open and then with eyes closed. The test will be conducted on a force platform, a Wii Balance Board (Nintendo Co., Ltd.), using the Colorado University BrainBLoX software. Anteroposterior and mediolateral sway (mm) of the body will be recorded by a custom-made code in MATLAB (The MathWorks, Inc. Natick, Massachusetts, United States).	Baseline and repeated before and after completing each 9-week protocol. There is a 1-week rest period between consecutive protocols.
Primary	Gaze stability as assessed by the Dynamic Visual Acuity (DVA) test	The setup of the test is similar to that of the Static Visual Acuity (SVA) test, the only difference being that the patient's head will be passively moved by the examiner in the horizontal plane at a 2Hz-frequency over an amplitude of 15° from centre. The difference between the SVA and the DVA score will be included as output measure.	Baseline and repeated before and after completing each 9-week protocol. There is a 1-week rest period between consecutive protocols.
Secondary	Functional mobility and dynamic postural control during walking as assessed by the Timed Up and Go Test (TUG)	The TUG test assesses functional mobility and dynamic postural stability during walking. Subjects, sitting 3m away from a wall, will be asked on the 'go' command to get up from the chair, walk towards the wall and touch it, come back to the chair and have a seat. Before the test, the procedure will be explained and demonstrated. Three trials will be conducted and the best time (recorded with stopwatch) will be used for analysis.	At the start of each 9-week protocol and at the very end of the complete trajectory (9-week protocol + 1-week rest period)
Secondary	Dynamic postural stability during walking as assessed by treadmill walking	Subjects will be asked to walk on an adaptive walking treadmill (Xiaomi WalkingPad C1®; Xiaomi Beijing, China; 144.9 cm x 52.8 cm x 11.7 cm). In order to normalize the walking pattern first, each child will start with a familiarisation period with a maximum duration of five minutes. Then, the participant will be asked to walk at a self-selected pace for 5 minutes. Using the Xiaomi Walkingpad software and two cameras (D3300, Nikon, Tokyo, Japan - operating at 50 frames/second, and D500, Canon USA, Inc., Melville, New York, USA - operating at 30 frames/second), information on a variety of spatiotemporal parameters will be collected: stride and step length (cm), step width (cm), step and stride time (s), and walking velocity (cm/s).	At the start of each 9-week protocol and at the very end of the complete trajectory (9-week protocol + 1-week rest period)
Secondary	Superior and inferior vestibular nerve and the functioning of the six semicircular canals, using the vestibulo-ocular reflex (VOR) assessed by the video Head Impulse Test (vHIT)	The children will be instructed to sit on a chair and fixate an attractive visual target (i.e. movie on a tablet) at 1.50 m distance. Meanwhile the examiner will perform unpredictable head movements (10° - 20° amplitude) in, respectively, the horizontal, LARP (to stimulate the left anterior and right posterior canal), and RALP plane (to stimulate the right anterior and left posterior canal). Prior to interpretation of the results, the data will be thoroughly cleaned according to the following criteria: (1) head velocity between 120°/s (vertical) or 150°/s (horizontal) and 250°/s (upper limit for vertical and horizontal), and (2) head bounce below 25 % of the peak head velocity. The measured gain (of the VOR) (%), the symmetry between the left and right side (%), and the presence of covert/overt saccades (n, and % of the performed HITs) will be taken as outcome measures of this test.	At the start of each 9-week protocol and at the very end of the complete trajectory (9-week protocol + 1-week rest period)
Secondary	Movement assessment battery for children, 2nd edition (MABC-2)	The purpose of the MABC-2 is the identification and description of impairments in motor performance of children 3-17 years of age. Children have to complete a series of fine and gross motor tasks grouped in three categories: manual dexterity, aiming and catching, and balance. These eight different and age appropriate tasks will yield a total score of the MABC-2, subscale scores and item scores to determine the level of motor competence of the participant.	At the start of each 9-week protocol and at the very end of the complete trajectory (9-week protocol + 1-week rest period)
Secondary	Quality of life as assessed by the Paediatric Quality of Life Inventory (PedsQL) 4.0	. It is a 23-item inventory, applicable for (parents of) children from 2 to 18 year. It consists of four subdomains: (i) physical functioning (eight items), (ii) emotional functioning (five items), (iii) social functioning (five items), and (iv) school functioning (five items). Items are scored through a 5-point rating scale.	At the start of each 9-week protocol and at the very end of the complete trajectory (9-week protocol + 1-week rest period)
Secondary	Static postural stability as assessed by the Single Leg Standing Test (SLS)	Subjects will be instructed to stand on one leg as long as possible. After explanation and demonstration of the procedure, children will be granted one attempt (for 10 seconds) to get familiar with the exercise. SLS will be carried out both with eyes open and with eyes closed and 3 trials will be conducted. Duration (s) will be the included response parameter for the SLS.	Baseline and repeated before and after completing each 9-week protocol. There is a 1-week rest period between consecutive protocols.
Secondary	Dynamic postural stability as assessed by the Paediatric Functional Reach Test	The Paediatric Functional Reach test is a measure for dynamic postural stability in both forward and lateral directions. After explanation and demonstration of the test, children will be instructed to reach as far forward and sideward as possible with their dominant hand and without moving the feet. Three trials will be conducted in each condition. The furthest reaching point subtracted by the reaching distance in neutral, symmetrical posture will be included for analysis (cm).	Baseline and repeated before and after completing each 9-week protocol. There is a 1-week rest period between consecutive protocols.
