The Hardy Effect.

View original source ↗Export metadata ↓

Abstract

PURPOSE: The late James C. Hardy completed an extensive investigation of respiratory muscle activity during speech production. The data set that resulted was probably the most comprehensive and instructive that has ever existed. One aspect of the data puzzled Hardy and caused him to question the validity of his findings and withhold his observations from publication. METHOD: This research note chronicles Hardy's thinking at the time (based on personal communications) and points out how the aspect of the data that puzzled him turned out to be a seminal discovery of a fundamental mechanism of speech breathing. CONCLUSION: It is proposed that, in his honor, this discovery be referred to as the Hardy Effect.

Pushing and pulling: personal mechanics influence spine loads.

This study assessed several mechanical issues related to low back loading during pushing and/or pulling tasks. Nine male participants performed two-handed pushing and pulling tasks at two handle heights with three loads, using a cable pulley system. Four of these men were professional firefighters trained in performing pushing and pulling tasks while the other five were graduate students who lacked manual work experience. The more experienced firefighters produced less spinal compression and shearing forces when compared to the less experienced students under the same conditions. The firefighters were able to create less muscle activation as compared to the students, which indicated a more efficient technique. The main contributing factors to the forces produced on the low back were the quantity of the load being pushed or pulled, handle height, experience level and the technique of the participant. Thus, attempts to set load limits for pushing and pulling tasks are difficult, since technique has such a large influence on back loading. In order to create safer working environments, education on proper pushing and pulling techniques is very important--more important than the physical variables in many cases.

Plating treatment for tibial plateau fractures: a biomechanical comparison of buttress and tension band positions.

INTRODUCTION: The load tolerance of conventional plate treatment for bicondylar tibial plateau fractures with the buttress and the tension band positions was compared from biomechanical viewpoints. MATERIALS AND METHODS: Fourteen left synthetic tibiae divided into two groups were tested. T-plates in the buttress group were placed on the medial tibial subcondyle and T-plates in the tension band group were placed on the lateral tibial subcondyle. All specimens were evaluated with a Material Testing System (MTS) machine. A linear variance displacement transducer gauge was placed on the medial tibial subcondyle. The anatomic axis of the synthetic femur and the tibia was maintained at 6 degrees varus in the frontal plane. The MTS actuator was set to increase displacement at 3 mm/min. All specimens were evaluated to failure. The relative motion and the ultimate failure load (UFL) between both groups were compared. RESULTS: The buttress group had significantly less displacement than the tension band group following the incrementally increased loading (p < 0.001). At failure, the buttress group also had a higher UFL (p < 0.001) and less displacement (p = 0.009) than the tension band group. CONCLUSION: All medial tibial condylar fragments achieved improved stabilization from the medial aspect of the proximal tibia by conventional plates. When conventional plates cannot be placed medially due to skin ailments, lateral placement of conventional plates may have the insufficient stability. Protected weight bearing should be followed strictly.

Mechanical concepts for disc regeneration.

Different strategies exist to treat intervertebral disc degeneration. Biological attempts to regenerate the disc are promising. However, degeneration of the disc is always accompanied by alterations of disc height, intradiscal pressure, load distribution, and motion patterns, respectively. Since those preconditions are independent factors for disc degeneration, it is unlikely that regeneration may occur without firstly restoring the physiological status of the affected spinal segment. In vitro and in vivo animal studies demonstrate that disc distraction normalizes intradiscal height and pressure. Furthermore, histological and radiological examinations provided some evidence for regenerative processes in the disc. Only dynamic stabilization systems currently offer the potential of a mechanical approach to intervertebral disc regeneration. Dynamic stabilization systems either using pedicle screws or with an interspinous device, demonstrate restabilization of spinal segments and reduction of intradiscal pressure. Clinical reports of patients with degenerative disc disease who underwent dynamic stabilization are promising. However, there is no evidence that those implants will lead to disc regeneration. Future treatment concepts should combine intradiscal cell based therapy together with dynamic restoration of the affected spinal segment.
