Regaining Upper Limb Function After Stroke: Combatting Weakness, Sensory Loss, and Pain Through Physiotherapy
Introduction
A stroke frequently results in upper limb challenges—such as weakness, loss of sensation, and pain—that severely impact daily life. Rehabilitation via physiotherapy offers targeted, evidence-based interventions that help mitigate these issues, promoting improved function and a better quality of life.
Understanding the Challenges
Weakness (Paresis): More than two-thirds of stroke survivors experience arm and hand motor impairment (paresis), which can hinder everyday tasks like reaching or grasping. The Lancet
Sensation Loss: Sensory impairments affect up to 50% of stroke survivors, both in the early (subacute) and later (chronic) stages, limiting motor control and the practical use of the affected arm. BioMed Central
Pain: Shoulder pain and subluxation frequently accompany upper limb weakness, interfering with recovery and rehabilitation.
Physiotherapy Strategies to Support Recovery
1. Repetitive, Task-Oriented Practice
High-dose, task-specific training is a cornerstone of neuroplastic recovery. Patients who receive more than 30 hours of therapy see small to large clinical improvements, particularly when the activities are functionally relevant. CSP
2. Constraint-Induced Movement Therapy (CIMT)
This approach promotes use of the affected arm by restraining the unaffected limb. CIMT—both traditional and modified—has been shown to produce sustained functional improvements and support cortical reorganization.
3. Mirror Therapy
By reflecting the movement of the unaffected limb, mirror therapy tricks the brain into activating pathways for the affected arm. Evidence supports its effectiveness in improving motor function and providing pain relief.
4. Functional Electrical Stimulation (FES)
Using electrical impulses to activate muscles, FES improves grip strength, reduces spasticity, and helps manage shoulder pain and subluxation. Benefits can persist for over two years post-intervention.
5. Sensory Re-Learning (Combined with Task Practice)
Sensory impairments themselves pose a barrier to motor recovery. The SENSUPP intervention integrates sensory re-learning with task-specific training—targeting both sensation and motor control—to enhance upper limb function. BioMed Central
6. Robotic & eHealth Technologies
Robotic Devices: A meta-analysis of 54 studies showed robotic-assisted rehab can augment conventional therapy and offer high repetition, though optimal device features and parameters vary. BioMed Central
Virtual Reality (VR) & Telerehabilitation: VR adds engagement, individualized feedback, and varied practice, showing similar or even superior benefits to traditional methods in improving function and daily activity performance.
Telerehabilitation: Promising for remote delivery and patient autonomy—but more work is needed on safety protocols and engagement strategies.
7. Self-Directed Repetition & Assistive Task Practice
Patients with sufficient motivation and ability can benefit from self-managed, practice-focused rehabilitation, supplemented by the team using techniques like mirror therapy or FES. National Clinical Guideline for Stroke

Conclusion
Upper limb recovery after stroke is multifaceted—touching on strength, sensation, and pain. The most effective physiotherapy approaches are those that are high in therapeutic intensity, task-specific, and tailored to individual needs. Techniques like CIMT, mirror therapy, FES, and sensory training promote neuroplastic adaptation and meaningful improvement. Blending traditional techniques with emerging tech like robotics or VR can enhance outcomes—especially when extended into patient-led practice.
