Proprioceptive Training With or Without Strength Training on Tibialis Anterior in Chronic Stroke Patients

Proprioceptive Training With or Without Strength Training on Tibialis Anterior in Chronic Stroke Patients

This randomized controlled trial aims to investigate the effects of proprioceptive training with and without tibialis anterior strength training in individuals with chronic stroke. Chronic stroke survivors commonly experience impaired balance, gait disturbances, reduced lower-limb muscle strength, and functional limitations that affect mobility and independence. The tibialis anterior muscle plays an important role in ankle dorsiflexion, foot clearance during walking, and postural stability.

Participants with chronic stroke will be randomly assigned to one of two intervention groups. One group will receive proprioceptive training combined with tibialis anterior strength training, while the other group will receive proprioceptive training alone. Interventions will be administered over a six-week period. Outcomes related to muscle strength, balance, gait performance, and functional mobility will be assessed at baseline and during follow-up assessments.

The study seeks to evaluate rehabilitation approaches targeting lower-limb motor and sensory impairments in individuals with chronic stroke and to contribute evidence regarding interventions designed to improve functional recovery and mobility.

Stroke is a major cause of long-term disability worldwide and is frequently associated with persistent motor and sensory impairments. Individuals living with chronic stroke often experience reduced muscle strength, impaired proprioception, balance deficits, gait abnormalities, and decreased functional mobility. These impairments can limit participation in daily activities and reduce overall quality of life.

The tibialis anterior muscle is an important component of lower-limb function because it contributes to ankle dorsiflexion during gait and assists with postural control. Weakness of this muscle following stroke may contribute to foot drop, reduced walking efficiency, impaired balance, and an increased risk of falls. Rehabilitation strategies that target both sensory and motor impairments may support recovery of lower-extremity function.

Proprioception refers to the ability to perceive joint position and movement through sensory input from muscles, tendons, and joints. Following stroke, disruption of sensory pathways may impair proprioceptive function and negatively affect motor performance. Proprioceptive training is commonly used in rehabilitation programs to improve sensory awareness, postural control, coordination, and movement quality through structured balance and functional activities.

Strength training is another established rehabilitation intervention used to address muscle weakness after stroke. Targeted strengthening exercises may improve force generation, neuromuscular activation, and lower-extremity performance during functional tasks. Strengthening the tibialis anterior muscle may assist with ankle control and walking-related activities.

This study will use a randomized controlled trial design. Participants diagnosed with chronic stroke who meet the eligibility criteria will be recruited from the University of Lahore Teaching Hospital. Following informed consent and baseline assessment, participants will be randomly allocated to one of two groups:

Group A: Proprioceptive training combined with tibialis anterior strength training.

Group B: Proprioceptive training alone.

The intervention period will last six weeks. Assessments will be conducted at baseline, Week 3, and Week 6. Outcome measures will evaluate lower-limb muscle strength, balance performance, gait characteristics, and functional mobility.

The study is designed to examine rehabilitation approaches commonly used in neurological physical therapy and to provide information regarding their application in individuals with chronic stroke. The findings may help guide future rehabilitation programs aimed at improving lower-extremity function, mobility, and participation in daily activities among stroke survivors.
