Best Leprosy Treatment in Delhi

What is Leprosy ?

Leprosy (Hansen’s disease) is a chronic infectious disease caused by Mycobacterium leprae. While treatable with multidrug therapy (MDT), its primary impact is on the skin, eyes, upper respiratory tract, and most significantly, the peripheral nerves. Nerve damage in leprosy can lead to progressive and irreversible disabilities and deformities, even after the infection is cured. This is where physiotherapy plays an absolutely critical and ongoing role.

The nerve damage in leprosy is often the main cause of disability. It commonly affects the ulnar, median, common peroneal, posterior tibial, facial, and great auricular nerves. This nerve damage leads to:

Sensory Loss: Numbness, loss of touch, pain, and temperature sensation. This is extremely dangerous as patients may injure themselves without feeling it (e.g., burns, cuts, pressure ulcers), leading to chronic wounds and infections.
- Motor Weakness/Paralysis: Weakness or paralysis of muscles supplied by the affected nerves, leading to:
- Hand Deformities: “Claw hand” (due to ulnar and median nerve damage), “drop wrist” (due to radial nerve damage).
- Foot Drop: Difficulty lifting the front part of the foot (due to common peroneal nerve damage), leading to a high-stepping gait.
- Foot Deformities: “Claw toes,” trophic ulcers (non-healing wounds) on the sole of the foot due to pressure and sensory loss.
- Eye Problems: Lagophthalmos (inability to close the eyelids completely due to facial nerve damage), leading to dry eyes, corneal damage, and blindness.
- Autonomic Dysfunction: Affecting sweating and skin moisture, leading to dry, cracked skin, which is more prone to injury and infection.
- Reactions (Lepra reactions): Acute inflammatory episodes that can cause further nerve damage and pain.

The Role of Physiotherapy in Leprosy Management

Physiotherapy is an integral part of the Disability Prevention and Medical Rehabilitation (DPMR) program for leprosy. It is a long-term commitment, often for the patient’s lifetime, to prevent, minimize, and manage disabilities.

Physiotherapy Approaches for Leprosy

Nerve Protection and Self-Care Education:
- Sensory Re-education: Teaching patients with sensory loss to protect their affected limbs from injury (e.g., using padded tools, wearing protective footwear, checking skin daily for wounds/blisters, avoiding extreme temperatures).
- Eye Care: Instructions for patients with lagophthalmos (e.g., “Think Blink” exercises, eye drops, protective eyewear, eyelid massage).
- Skin Care: Daily oiling/moisturizing of dry skin, wound care management for ulcers.
Maintaining and Improving Range of Motion (ROM):
- Passive Range of Motion (PROM): Performed by the therapist or caregiver to prevent joint stiffness and contractures, especially in paralyzed limbs (e.g., for claw hands or foot drop).
- Active Range of Motion (AROM): Encouraging patients to move their joints actively within their available range.
- Stretching: Targeted stretches for muscles prone to tightness and contracture.
- Serial Splinting: Applying splints (static or dynamic) to maintain a stretched position for contractures (e.g., for finger contractures or thumb web contractures).
Strengthening and Muscle Re-education:
- Graded Strengthening Exercises: For weak or partially paralyzed muscles, using body weight, resistance bands, or light weights.
- Biofeedback: To help patients re-learn to activate specific weak muscles.
- Electrical Stimulation (NMES/FES): To stimulate weak or paralyzed muscles, maintain muscle tone, prevent atrophy, and potentially facilitate nerve healing.
Splinting and Orthotic Management:
- Protective Splints: To prevent deformities and protect anesthetic limbs (e.g., night splints for claw hands, protective footwear for feet) .
- Functional Splints/Orthoses: To assist function (e.g., AFOs for foot drop to aid walking, dynamic hand splints to assist grasp).

Gait Training:
- For patients with foot drop or other lower limb deformities, gait training focuses on improving walking patterns, stability, and efficiency, often with the use of orthoses.
Pain Management:
- Manual therapy, massage, heat/cold, and modalities like TENS for neuropathic pain or muscle pain.

Advanced Physiotherapy Techniques for Leprosy

“Advanced” physiotherapy in the context of leprosy often refers to highly specialized and integrated approaches aimed at optimizing nerve regeneration, functional recovery, and long-term prevention of disability, especially when traditional methods are insufficient or for complex cases.

Low-Level Laser Therapy (LLLT):
- Emerging research suggests Laser can be a promising adjunctive therapy. It uses specific wavelengths of light to stimulate cellular repair, reduce inflammation, and may promote nerve regeneration, improve sensory function, and reduce pain in affected nerves. This can be particularly beneficial for neuritis (nerve inflammation) and nerve function impairment.
Advanced Neuromuscular Re-education and Motor Control:
- Beyond basic strengthening, this involves highly specific exercises designed to rewire neural pathways and improve precise control of muscles. This can include:
- Task-specific training: Practicing real-life tasks that are challenging due to nerve damage.
- Mirror therapy: For unilateral weakness/sensory loss, using a mirror to create the illusion of movement in the affected limb, which can stimulate cortical reorganization.
- Neurodynamic Mobilization:
- Gentle, specific movements that mobilize peripheral nerves along their pathways. This can help reduce nerve entrapment, improve nerve gliding, reduce pain, and potentially enhance nerve health and regeneration, especially important in a condition characterized by nerve inflammation and damage.
Advanced Wound Care and Pressure Mapping:
- While often overseen by specialized nurses, physiotherapists are integral. Advanced techniques might include using pressure mapping technology to identify high-pressure areas on the feet or hands to guide custom footwear/orthotic design and pressure relief strategies, preventing chronic ulcers.
- pecialized Footwear/Orthotics: Collaborating with orthotists to design highly customized footwear and braces that redistribute pressure, accommodate deformities, and support paralyzed muscles.
