Do Knee Injuries have Long-Term Consequences for Isometric and Dynamic Muscle Strength?

European Journal of Applied Physiology
August 2001 Volume 85, Number 3

Holder-Powell HM; Di Matteo G; Rutherford OM Applied Biomedical Research Group, GKT School of Biomedical Sciences, Kings College, London, Guy’s Campus, London SE1 1UL, UK

Study Outcomes & Clinical Relevance:

Despite the popularity of “functional rehabilitation” that emphasizes compound movements, this study, like several others, documents weak links in the kinetic chain long after function has supposedly been regained. Complex movements may involve a number of motor compensations that create an illusion of normalcy, but the best way to detect persistent underlying anomalies is through isolated joint testing. The knee medical machine manufactured by MedX is capable of identifying such disparities through multiangular isometric testing and treating deficiencies with dynamic variable resistance.

Differences in Back Extensor Strength Between Smokers and Nonsmokers with and without Low Back Pain

Journal of Orthopedic Sports Physical Therapy
May 2004, Volume 34, Number 5

Al-Obaidi SM, Anthony J, Al-Shuwai N, Dean E Department of Physical Therapy, Faculty of Allied Health Sciences and Nursing, Kuwait University, Kuwait

Study Outcomes & Clinical Relevance:

Individuals who smoked were weaker than those who did not smoke, but no difference in strength was noted between smokers with and without LBP.

Although smoking appears to be an important cofactor In the etiology of LBP, the degree to which smoking is a primary, secondary, or a component of a combined etiology warrants further study.

Strength Testing of the Isolated Cervical Spine: A Five-Year Follow-Up

Abstract Presentation Columbia, Missouri
October 24, 1996

Thomas E. Dreisinger, PhD, Laura L. Vie, MAEd, Thomas Highland, MD

Study Outcomes & Clinical Relevance:

The five year follow-up showed that patients had lost cervical extension strength from the initial training. Even after five years, however, peak torque had remained significantly greater than the initial strength test.
