How does one protect the anesthetic feet of leprosy patients? This was the question which was uppermost in the minds of people like Dr. Paul Brand, Surgeon, Mr. David Ward Physiotherapist & others who worked in Karigiri in the early sixties. What material would fulfill the requirement of protection and softness? Would rubber be suitable? The medical fraternity had little knowledge about the properties of rubber. Dr. Brand approached the Chairman of the MRF, Mr. Mammen Mappillai, whose relative Dr. Brand had operated on. The connection with MRF started there and it continues to this day.
Micro Cellular Rubber (MCR) was developed at the Karigiri Hospital in 1965, in collaboration with the R&D wing of the Madras Rubber Factory (MRF), Chennai. Mr. George John was deputed to work on with the Karigiri team. It has been used extensively, to address the needs of leprosy patients. Mr. K M Mammen Mappillai, was instrumental in providing resources and technical support freely to Karigiri to develop MCR as part of his social concern. In recognition of this contribution, the MCR facility at Karigiri was named the K M Mammen Mappillai Micro Cellular Rubber Unit in 2006.
What is MCR?
MCR is a specially processed rubber material, where bubbles of air are introduced into the rubber, creating “micro-cells” that generate a controlled amount of softness and cushioning.
SIH-R & LC is in the process of further improving quality and has excellent testing equipment to ensure an extremely high level of quality. We gratefully acknowledge the contribution made by the Rubber Research Institute of India (RRII), Kottayam towards this critically important activity.
DIABETES is increasingly becoming a very common condition in India. Prolonged diabetes, more often than we think, leads to loss of sensation in the feet. KARIGIRI MCR can therefore be utilized to add its protective effect of softening impact and redistributing pressure. It can be made in different grades of softness, based on the particular need for prevention, protection or other requirements.
Special features of Karigiri MCR
Scientifically proven degree of softness
Even re-distribution of pressure
Good abrasion resistance, cushioning effect, flexing and resilience property
Durable and low cost
KARIGIRI MCR footwear is not only useful for persons with diabetes, but also for management of various foot problems like heel pain, corns, callosities and fissures.
KARIGIRI MCR footwear helps to redistribute bodyweight, thereby significantly delaying the onset of problems. Use of KARIGIRI MCR, combined with a sound, common-sense approach to care of the feet, can be extremely rewarding.
KARIGIRI MCR is in demand all over India and in neighbouring counties.
Uses of KARIGIRI MCR in foot & hand care:
As a standard insole for footwear: attaching to it Uppers/Straps of leather or synthetic material.
As shoe inserts to correct for a variety of podiatric irregularities such as corns, callosities, prominent metatarsal heads, fallen arches, and other unusual deformations of feet due to disease, faulty shoes, or trauma.
As a lining for custom-made moulded insoles
As padding for the soft socket in prosthetic devices (artificial limbs)
As protective grips in various upper limb orthotic devices (assistive aids).
MCR Sheet 10 mm thickness, 21” x 18” size, adequate for approximately 5 pairs of insoles
MCR Sheet 3 mm thickness, 16” x 10” size, adequate for approximately 2 pairs of moulded insoles.
