Neurological Physiotherapy Treatment Protocol for Thalamic Bleed Stroke Survivor

Overview of Conditions

A thalamic bleed refers to a hemorrhage within the thalamus, a vital brain structure responsible for relaying sensory and motor signals between the cortex and spinal cord. Damage to the thalamus can result in a range of sensorimotor deficits, influencing pain perception, movement coordination, and sensory integration. Thalamic hemorrhages often lead to motor deficits, sensory disturbances, and cognitive impairments.

Clinical Manifestations

• Sensory Loss: Contralateral deficits in proprioception, fine touch, pain, and temperature sensation, often accompanied by thalamic pain syndrome (Dejerine-Roussy syndrome), characterized by spontaneous burning pain.
• Motor Deficits: Hemiparesis, especially in the upper limbs, with some degree of weakness in the lower limbs.
• Coordination Issues: Ataxia, dysmetria, and dystonia due to thalamic involvement in motor coordination.
• Cognitive Changes: Difficulties in attention, memory, and executive function, though less common.
• Pain Syndromes: Persistent, burning pain due to thalamic damage, requiring specialized management.
• Visual and Speech Deficits: Rare, but may occur depending on the extent of damage to adjacent brain areas.

Symptomatology and Probable Deficits

• Sensory Dysfunction: Loss of sensation, including proprioception, tactile sense, and nociception (pain and temperature).
• Motor Dysfunction: Hemiparesis, most pronounced in the upper limbs, along with possible ataxia and dysmetria.
• Coordination Problems: Ataxia, tremors, and difficulty performing fine motor tasks.
• Pain: Persistent burning or aching pain from thalamic pain syndrome.
• Cognitive and Emotional Deficits: Decreased attention, processing speed, and memory.
• Gait and Postural Instability: Weakness and sensory deficits affecting mobility and balance.

Assessment and Evaluation

1. Functional Task Impairment Assessment:
   • Fugl-Meyer Assessment (FMA): Assesses motor function and coordination, especially in the upper limbs.
   • Modified Ashworth Scale (MAS): Evaluates spasticity in affected limbs.
   • Berg Balance Scale (BBS): Assesses balance and fall risk.
   • Sensory Integration and Proprioception Tests: For evaluating sensory loss in the affected limbs.
   • Thalamic Pain Assessment: To gauge the presence and severity of thalamic pain.
   • Montreal Cognitive Assessment (MoCA): Assesses cognitive deficits, including attention, memory, and executive function.
   • Functional Independence Measure (FIM): Measures independence in daily activities.
2. Key Functional Impairments:
   • Sensory Dysfunction: Loss of sensation in the affected limbs, particularly for proprioception and pain perception.
   • Motor Dysfunction: Hemiparesis with motor coordination issues like ataxia.
   • Pain: Severe, persistent pain from thalamic pain syndrome.
   • Coordination Deficits: Ataxia and difficulty with fine motor tasks.
   • Cognitive Deficits: Reduced attention, memory, and executive function.
   • Gait and Postural Instability: Weakness and sensory deficits affecting mobility.

Goal Setting

• Short-term Goals (2-4 weeks):
  • Reduce spasticity and improve motor control, especially in the upper limbs.
  • Address thalamic pain with sensory re-education and pain management techniques.
  • Improve functional movement patterns (e.g., self-feeding, dressing).
  • Promote cognitive recovery, particularly in attention and memory.
• Long-term Goals (6-12 weeks):
  • Achieve functional independence in basic ADLs (e.g., bathing, dressing).
  • Improve gait and balance using targeted rehabilitation techniques.
  • Alleviate thalamic pain with multimodal pain management.
  • Restore upper limb coordination and fine motor control.
  • Enhance cognitive function using tailored rehabilitation strategies.

Recommended Interventions

1. Motor Relearning Program (MRP):
   • Description: Focuses on task-specific training to improve motor control through repetitive functional movements.
   • Protocol:
     • Start with simple tasks (e.g., grasping, reaching).
     • Progress to more complex functional tasks (e.g., self-feeding, writing).
   • Evidence: Task-specific training is effective for improving motor function post-stroke (Ada et al., 2021).
2. Constraint-Induced Movement Therapy (CIMT):
   • Description: Involves constraining the unaffected limb to encourage use of the affected limb.
   • Protocol:
     • Constrain the unaffected limb and engage in repetitive functional tasks with the affected limb.
     • Start with simple tasks, progressing to more complex ones.
   • Evidence: CIMT enhances motor control, especially in the upper limb (Taub et al., 2021).
3. Thalamic Pain Management:
   • Description: Specialized interventions to manage persistent thalamic pain.
   • Protocol:
     • Use TENS for pain modulation.
     • Incorporate sensory re-education to expose the brain to varied textures and temperatures.
   • Evidence: TENS and sensory re-education help reduce pain and promote sensory recovery (Housman et al., 2021).
4. Gait and Balance Training:
   • Description: Address postural instability and gait deficits.
   • Protocol:
     • Begin with supported walking exercises, progressing to unsupported walking.
     • Incorporate balance exercises and obstacle navigation.
   • Evidence: Task-specific gait training improves mobility and reduces falls (Hornby et al., 2020).
5. EMG Biofeedback Therapy:
   • Description: Utilizes muscle activity feedback to promote motor control and muscle activation.
   • Protocol:
     • Use surface EMG electrodes on affected muscles to monitor and encourage voluntary activation.
   • Evidence: EMG biofeedback improves motor function post-stroke (Lindberg et al., 2021).
6. Electrical Muscle Stimulation (EMS):
   • Description: Uses electrical impulses to stimulate muscle contraction, preventing atrophy.
   • Protocol:
     • Apply EMS to affected muscles (e.g., lower limbs, hands).
     • Combine EMS with functional tasks to improve neuromuscular function.
   • Evidence: EMS promotes muscle strength and functional recovery (Housman et al., 2021).
7. Proprioceptive Neuromuscular Facilitation (PNF):
   • Description: Uses diagonal patterns of movement to improve motor control and coordination.
   • Protocol:
     • Implement PNF patterns to facilitate movement in both upper and lower limbs.
     • Utilize contract-relax and hold-relax techniques to improve range of motion and strength.
   • Evidence: PNF improves motor function and coordination post-stroke (Lobasso et al., 2021).
8. Neurodevelopmental Treatment (NDT):
   • Description: Involves handling techniques to reduce abnormal muscle tone and improve movement patterns.
   • Protocol:
     • Use positioning and handling techniques to normalize muscle tone.
     • Guide the patient through functional movements.
   • Evidence: NDT improves posture and mobility in stroke rehabilitation (Bourbonnais et al., 2021).

Reassessment and Criteria for Progression

• Reassess motor control, functional mobility, and pain every 2-4 weeks.
• Progress based on motor recovery, pain reduction, and independence in ADLs.
• Adjust treatment plans based on ongoing assessments, especially if thalamic pain remains problematic.
