ISOKINETIC STRENGTH AFTER TEARS OF THE SUPRASPINATUS TENDON
The Journal of Bone and Joint Surgery. British volume, 1997We measured the isokinetic strength of abduction, adduction, internal rotation, and external rotation in ten patients with full-thickness tears of the supraspinatus and ten with partial-thickness tears. The measurements were repeated after intra-articular or intrabursal injection of local anaesthetic.

Shoulder Strength With Rotator Cuff Tears
Clinical Orthopaedics and Related Research, 1993Twenty-five patients with rotator cuff tears had bilateral isokinetic shoulder strength evaluations after a pain-relieving subacromial lidocaine injection. Shoulder strength testing was repeated at six months and again at 12 months after rotator cuff surgery. Strength was recorded as a ratio of peak torques comparing the operative with the nonoperative

Effect of Oxygen on the Tear Strength of Elastomers
Rubber Chemistry and Technology, 1990Abstract Many measurements have been made of the strength of simple vulcanizates of common elastomers, both under steady and intermittently applied loads. In both cases, the strength is governed by dissipative processes, particularly those arising from internal molecular motions and from stress-induced crystallization.

Strength Training in the Rehabilitation of Cruciate Ligament Tears
Sports Medicine, 1990Pure strength training will result in good functional results in most patients with anterior or posterior cruciate ligament injuries. In a randomised study it was shown that functional training without specific strength training will result in at least comparable results to isokinetic training. In order to increase compliance and to improve the results

Tear strength of oriented crystalline polymers
Journal of Materials Science, 1986Three crystalline polymers; high- and low-density polyethylene andtrans-polyisoprene; were prepared as sheets with varying degrees of molecular orientation. Measurements of the energyG c required to propagate a tear along and across the direction of orientation are described.

Tear strength of ductile polyolefin films
Polymer Engineering & Science, 2002AbstractA reinforced trouser tear test was developed to evaluate the tear resistance of thin ductile films. Tests with blown film of linear low‐density polyethylene blended with up to 30 wt% of a high melt strength polypropylene (hmsPP) demonstrated that the test differentiated among films based on composition and thickness.

The Tearing Strength of Chemically Modified Pericardium
1989Destructive uniaxial load tests were performed on chemically modified bovine pericardium. Five specimens were selected from the same sites in different pericardial sacs by using a template. To investigate the tearing strength of this material, an artificial tear, in the form of a 2mm notch, was introduced into the test specimens.

The Measurement of Tearing Strength of Textile Fabrics
Textile Research Journal, 1956Current versions of two methods commonly used for the determination of tearing strength require clarification regarding treatment of the data obtained and revision to accommodate newer types of inertialess testing machines. Experimental information, providing the necessary background data, has been obtained.

Pull-Tear Strength Capabilities in Adults
Proceedings of the Human Factors Society Annual Meeting, 1987Forty-four adults between the ages of 22 and 40 years were tested for maximal volitional pulls with the fingers, similar to some pull-tear forces employed for opening packages with tear strips. Twelve different pull conditions were tested-3 types of pull X 2 directions of pull X 2 hands.
