Brief Summary

The aim of this study is to assess both immediate and long-term effects of visually-guided gait training on balance, mobility, and risk of falling in patients with multiple sclerosis.

Detailed Description

Balance and mobility impairments are the most common deficits in people with multiple sclerosis (MS), arising early in the disease course and gradually progressing over time, leading to loss of independence and quality of life. Moreover, static, and dynamic balance deficits in MS patients have been demonstrated to play a major role in patients' perception of walking ability during daily life and in predicting future falls. Given the strong impact of balance impairments on MS patients' disability.

Also, it was reported that the ability to coordinate visual information with movement is normally important to interact with the environment. Indeed, visually guided walking requires the brain to maintain an accurate relationship (or visuomotor mapping) between the perceived stepping location and the motor command necessary to direct the foot to that position on the ground with minimal error. Besides, previous research reported that people with MS, with neuronal transmission impairment or lesions on somatosensory ways, are more dependent on visual compensation for maintain balance. As lesions on somatosensory ways alter postural stability as this fundamental feedback is impaired, making a postural compensation and the visual feedback often more necessary to maintain balance.

To overcome these highly disabling issues, different rehabilitative approaches have been proposed so far in the literature. However, rehabilitation interventions in individuals with MS are limited to aerobic, resistance, and combined aerobic and resistance exercises and instrumental adapted exercise modalities including body-weight-supported treadmill walking or robotic technology. Few studies have addressed the effects of external sensory stimulations (visual, auditory) during gait training on motor performance in patients with multiple sclerosis.

So, visually-guided gait training could be beneficial for improvement of balance and mobility measures and decrease risk of falling for people with MS.

• Blinding Strategy: NONE

Study Groups

Visually-guided gait training + Conventional gait training

This group will consist of twenty patients, who will receive visually-guided gait training and conventional gait training for 8 weeks.

Group Type: EXPERIMENTAL

Visually-guided gait training

Intervention Type: OTHER

The program runs for eight weeks, with two 60-minute sessions per week, integrating gaze strategy, task-specific mobility, and dual-task cognitive training. Participants first learn systematic visual scanning using saccades and gridline searches. In task-specific training, they perform precision walking-stepping accurately on targets-and obstacle avoidance, navigating a 6 m path with variable pole positions to enhance visual-motor coordination. Finally, dual-task training adds cognitive challenges, such as word generation or backward counting, to improve attention, adaptability, and functional mobility.

Conventional gait training

Intervention Type: OTHER

It will be received for eight weeks, twice per week, each session lasting 30 minutes, consisting of standing and walking activities maintaining a stable base of support; static postural control exercises, weight shifting and perturbations exercises, weight-bearing exercises through lower limbs; and adequate weight transfer and forward progression with trunk, limb, and pelvic kinematics consistent with safe walking, walking forward and backward, side-stepping, standing and walking on varied surfaces.

Conventional gait training

This group will consist of twenty patients, who will receive conventional gait training only for 8 weeks.

Group Type: ACTIVE_COMPARATOR

Conventional gait training

Intervention Type: OTHER

It will be received for eight weeks, twice per week, each session lasting 30 minutes, consisting of standing and walking activities maintaining a stable base of support; static postural control exercises, weight shifting and perturbations exercises, weight-bearing exercises through lower limbs; and adequate weight transfer and forward progression with trunk, limb, and pelvic kinematics consistent with safe walking, walking forward and backward, side-stepping, standing and walking on varied surfaces.
