Immersive Virtual Environments and Wearable Haptic Devices in Rehabilitation of Children With Neuromotor Impairments

The investigators proposed a controlled, single-blind, unicentric, crossover, randomized, clinical trial to test the effects of immersive virtual environments and wearable haptic devices in the rehabilitation of children with neuromotor impairments. In addition, the proposed approach was compared with respect to conventional therapy.

A sample of 8 participants was randomly divided into 2 groups and they attended one of the two therapeutic approach for 4 weeks before crossing over and inverting the therapy. Between the two interventions, there was a wash out period of 4 weeks.

The investigators assessed motor abilities of the children with validated clinical scales and motion analysis before/after each phase of the study (T0: baseline, T1: after 4 weeks, T2: after 8 weeks, T3: after 16 weeks, and T4: up to 24 weeks).

About this study

A Randomized Controlled Crossover Trial was designed to examine the usability and effectiveness of serious games and wearable haptic interfaces in rehabilitation of children with neuromotor impairments. The ethics board of Tuscany Region and the Italian Ministry of Health approved this study. All parents freely accepted the participation of their children in the study and provided written informed consent.

The investigators recruited eight patients, both male and female, 3 children with Cerebral Palsy (CP) and 5 children with Developmental Dyspraxia (DD) (mean age = 10,30±2,88 years), who were currently receiving conventional therapy at Unit of Developmental Neurorehabilitation, Maternal and Child Department, Pisa University Hospital, and eight Typically Developing children (TD, mean age = 9,60±2,61 years). All the patients were right-handed and they did not have previous experiences with Virtual Reality (VR) and/or haptic devices, while TD children have previously experienced with commercial video games.

Following recruitment, screening and consent and baseline assessments, participants are randomized to an order of VR-assisted rehabilitation (ISG-Group, Immediate Serious Games, or DSG-Group, Delayed Serious Games). Participants were setup in their first condition and were assessed at the end of the 4 week intervention. Participants were then set up in their second period for 4 weeks, again with assessment occurring at the end of the intervention. Among the two interventions, a wash out period of 4 weeks was inserted and children followed only cognitive therapy with no physical sessions.

The study protocol consisted of a total of 16 sessions with both VR-assisted and conventional rehabilitation (2 sessions per week for 4 weeks for 2 periods) and involved a familiarization and a training phase. The investigators adopted different established clinical scales for children with CP and DD in order to assess patients' abilities during the assessments. The investigators also selected metrics obtained from end-point (hand) kinematic data, including movement speed and accuracy, in order to have quantitative measurements of patients' motor abilities.

Treatment and study plan

Serious Game

Device

Serious Game (SG) refers to the use of immersive virtual environments and wearable haptic devices during the treatment. Two SG were specifically developed to allow a playful training of different, targeted Upper Limb (UL) movement based on typical rehabilitation exercises (reach-to-grasp, linear path tracking, hand orientation). The child interacts directly with a virtual environment through haptic feedback provided to his/her fingertips. In particular, "moneybox game" focused on pincer grasp and reaching tasks with pronation/supination od the hand while "marble labyrinth game" focused on pointing and tracking movements requiring both eye-hand and upper limb inter-joint coordination.

Conventional Therapy

Other

Conventional therapy (CONV) refers to the neurocognitive rehabilitation approach, with the purpose of improving pointing, tracking, reaching and grasping, and pronation/supination of the forearm. The therapeutic sessions were performed with the exception of the visual channel to ensure that the child focused his/her attention on tactile/kinesthetic information to complete the task. In particular, five different tasks have been proposed during the sessions: 1) recognize trajectories; 2) arm proprioception; 3) object manipulation; 4) recognize surfaces; 5) forearm orientation.

Primary outcomes

  1. Change From Baseline in Time Scores on Nine Hole Peg Test (9-HPT) for both Dominant and Non-Dominant Hands at 4, 8, 16 and 24 weeks

    Time frame: Baseline (T0), 4 weeks (T1), 8 weeks (T2), 16 weeks (T3), 24 weeks (T4)

    Nine Hole Peg Test (9-HPT) is a brief, standardized, quantitative test of upper extremity function. Both the dominant and non-dominant hands are tested twice. The child is seated at a table with a small, shallow container holding nine pegs and a wood or plastic block containing nine empty holes. On a start command when a stopwatch is started, the child picks up the nine pegs one at a time as quickly as possible, puts them in the nine holes, and, once they are in the holes, removes them again as quickly as possible one at a time, replacing them into the shallow container. The total time to complete the task is recorded.

  2. Change From Baseline in Kinematic Metrics on Linear Path Tracking (LPT) and Reach-to-Grasp (RtG) Tasks for Dominant Hand at 4, 8, 16 and 24 weeks

    Time frame: Baseline (T0), 4 weeks (T1), 8 weeks (T2), 16 weeks (T3), 24 weeks (T4)

    The evaluation task consisted of two reach-to-grasp tasks requiring forearm pronation or supination and three linear path tracking (forward and sideways). For the RtG task, the child was asked to flip a card protruding from an horizontal support. For the LPT, the child was seated in front of a desk with the hand positioned, at rest, close to the body on the sagittal plane. Then a target was put on the desk (always at the same distance from the starting position) and the child was asked to reach the target by moving the hand along a straight path. All tasks were performed with the preferred arm at self selected speed. The investigators then extracted kinematic metrics (movement speed, accuracy and smoothness) from end-point (hand) kinematic data.

Secondary outcomes

    Time frame: Up to 16 weeks

    The investigators referred to the following System Organ Class (SOC): Eye disorders, General disorders and administration site conditions, Nervous system disorders, Psychiatric disorders.
