Eccentric

Eccentric (n) ec·cen·tric is a term used to describe a type of movement or exercise. Eccentric Definition: The word concentric is most commonly used in sports science and medicine. In these settings eccentric defines a type of exercise or movement. Translated literally eccentric means away from the centre. Whenever a muscle lengthens it generates a contractile force meaning all movements in the body occur…
Why Use Isokinetic (s)?

Isokinetic motion is unique in that the force developed by the subject is equally matched by the machine. Isokinetics has been shown to effective in many situations. Below are specific examples for selected joints: Knee: All the below authors used isokinetic strength as the gold standard measure following arthroscopy. In fact in ACL rehab: Amongst…
Lumbar Spine Flexion and Extension

Testing of the trunk is limited on the 3 largest dynamometers on the market at the moment to flexion and extension of the lumbar spine. There have been trunk machines in the past which offered rotation and side flexion but they appear to have been phased out. CSMI/Cybex offer a standing unit which attaches onto…
Ankle Plantar / Dorsi Flexion

Plantar and dorsi flexion are normally performed in either the supine (or modified supine / seated), prone or standing positions. The ankle poses problems not shared by the knee joint. As it is such a polyarticulating area with a wide variety of movements and allot of muscles spanning it, the ankle throws up many procedural issues,…
Ankle Inversion / Eversion

Inversion and Eversion are normally performed in the supine or modified supine (seated) positions. The ankle poses problems not shared by the knee joint. As it is such a polyarticulating area with a wide variety of movements and allot of muscles spanning it, the ankle throws up many procedural issues, like positioning and alignment, and issues…
Hip Flexion / Extension

Testing hip flexion and extension is becoming more popular. Largely because of the increase in hip arthroscopies. More research is available although it is often contradictory. Femoroacetabular Impingement (FAI): Casartelli et al.(2012) described decreased isokinetic (and isometric strength tested on a isokinetics machine) muscle strength of the hip flexors in patients with femoral acetabular impingement syndrome (FAI),…
Hip Abduction / Adduction

Another test rising in popularity due to FAI and falls. Femoroacetabular Impingement (FAI): Hip muscle function has been said to be altered in patients with FAI. Casartelli et al. (2012) described decreased isometric muscle strength (tested using an isokinetics machine) of the adductors and abductors compared with controls. However, Diamond et al. (2015) only found…
Hip Internal / External Rotation

In recent years the use of hip testing both isokinetic and isometric testing has been on the increase. The main areas the research has seemed to focus on are: Femoroacetabular Impingement (FAI)Brunner et al. 2016Diamond, Wrigley, Hinman 2015Casartelli et al1. 2014Casartelli et al2. 2012 Hip muscle function has been said to be altered in patients…
Forearm Pronation / Supination

There are currently no standard examination positions for pronation and supination. During these movements the shoulder is difficult to fully stabilize without using 90 degrees of shoulder abduction and even then the subject can move the shoulder somewhat the elbow is usually flexed to 90 degrees during these tests (as described by Gallager et al…
Wrist Pronation / Supination

There are currently no standard examination positions for pronation and supination. During these movements the shoulder is difficult to fully stabilize without using 90 degrees of shoulder abduction and even then the subject can move the shoulder somewhat the elbow is usually flexed to 90 degrees during these tests (as described by Gallager et al…
