Abstract
Abstract A method and device for the prevention of and the treatment for epicondylalgia externa, popularly known as Tennis Elbow, is disclosed. The method involves the absorption and dissipation of the vibrational shocks caused by the off-center hitting of a tennis ball during pronation and supination of the wrist. The device employs a vibration absorbing pad covering either the extensor or flexor muscles of the forearm. The pad is tightly located against the said muscles by means of an elastic tube from the wrist area to the elbow. An elastic strap, located outside the aforementioned tube around the largest diameter of the forearm and fastened by Velcro or like fasteners, is an additional member for maintaining the pad in close contact with the arm surface. The aforementioned pad, shaped to conform with the extensor or flexor muscle in the forearm, is filled with a viscous fluid or semi-fluid which will flow enough to maintain a close contact with the muscle from wrist to elbow. The viscous fluid absorbs the surface vibrations caused by the off-center striking of a ball with a racquet. These vibrations are normally conducted along the extensor or flexor muscles of the forearm and are a direct cause of the inflammation of the elbow itself.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
136 words
A device for treating epicondylalgia externa, which comprises: pad means containing vibration-absorbing high viscosity permanently-fluid material dimensioned to extend over an area of the forearm of a wearer of the device which is at least half of the area of the extensor or flexor muscles in the forearm projected to the forearm surface, said high viscosity permanently-fluid material being a high viscosity liquid which is selected from the group consisting of liquid silicones and liquid uncured thermal setting glues, and a forearm-encircling tubular member contoured to fit over a forearm and having said pad means mounted to an internal surface theroef, whereby said pad means may be maintained in contact with the forearm, said tubular member comprising a conical sleeve constructed of a fabric which is stretchable only in the circumferential direction of said tubular member.
Claim 2
Independent Claim
136 words
A device for treating epicondylalgia externa, which comprises: pad means containing vibration-absorbing high viscosity permanently-fluid material dimensioned to extend over an area of the forearm of a wearer of the device which is at least half of the area of the extensor or flexor muscles in the forearm projected to the forearm surface, said high viscosity permanently-fluid material being a high viscosity liquid which is selected from the group consisting of liquid silicones and liquid uncured thermal setting glues, and a forearm-encircling tubular member contoured to fit over a forearm and having said pad means mounted to an internal surface theroef, whereby said pad means may be maintained in contact with the forearm, said tubular member comprising a conical sleeve constructed of a fabric which is stretchable only in the circumferential direction of said tubular member.
Claim 3
Independent Claim
125 words
A device for treating epicondylalgia externa, which comprises: pad means containing vibration-absorbing high viscosity permanently-fluid material dimensioned to extend over an area of the forearm of a wearer of the device which is at least half of the area of the extensor or flexor muscles in the forearm projected to the forearm surface, said high viscosity permanently-fluid material being a material having a viscosity resembling that of putty, and a forearm-encircling tubular member contoured to fit over a forearm and having said pad means mounted to an internal surface thereof, whereby said pad means may be maintained in contact with the forearm, said tubular member comprising a conical sleeve constructed of a fabric which is stretchable only in the circumferential direction of said tubular member.
Claim 4
Independent Claim
125 words
A device for treating epicondylalgia externa, which comprises: pad means containing vibration-absorbing high viscosity permanently-fluid material dimensioned to extend over an area of the forearm of a wearer of the device which is at least half of the area of the extensor or flexor muscles in the forearm projected to the forearm surface, said high viscosity permanently-fluid material being a material having a viscosity resembling that of putty, and a forearm-encircling tubular member contoured to fit over a forearm and having said pad means mounted to an internal surface thereof, whereby said pad means may be maintained in contact with the forearm, said tubular member comprising a conical sleeve constructed of a fabric which is stretchable only in the circumferential direction of said tubular member.
Claim 5
Independent Claim
135 words
A device for controlling epicondylalgia externa in a person to minimize the incidence thereof or to relieve the symptoms thereof, which comprises: pad means containing vibration absorbing high viscosity permanently-fluid material, said high viscosity permanently-fluid material being a high viscosity liquid which is selected from the group consisting of liquid silicones and liquid uncured thermal setting glues, said pad means being dimensioned to extend over an area of the forearm of a wearer of the device which is at least half the area of extensor or flexor muscles in the forearm projected to the forearm surface, and means for holding and maintaining said pad means in contact with said forearm, thereby to dampen and absorb surface vibration in said extensor and flexor muscles and minimize traumatization and consequent inflammation of the epicondyle of the forearm.
