Shoulder Rotation

In recent years the most popular isokinetic test in the shoulder has been internal/ externalrotation (with modified seated in the scapular plane being the most popular). The main reason this test has become so popular is the open chain nature of shoulder motions. Most movements around the shoulder in everyday life, and in fact sport,…
Shoulder Flexion / Extension

There are currently no standard examination positions for flexion and extension of the shoulder. During the movements of the gleno-humeral joint there are always relative movements within the scapulo-thoracic junction. These are usually described as fitting a set of established normal patterns. These must be considered when testing the shoulder. When testing or exercising the shoulder…
Shoulder Abduction / Adduction

These movements can be performed in either the standing or seated positions. There are currently no standard examination positions for abduction and adduction of the shoulder. During the movements of the gleno-humeral joint there are always relative movements within the scapulo-thoracic junction. These are usually described as fitting a set of established normal patterns. These must be considered…
Shoulder Diagonals

There are two main diagonal patterns available on isokinetic machines. They mimic the proprioceptive neuromuscular patterns (PNF). The two movements are: PNF 1: Extension / abduction / external rotation to flexion / adduction / internal rotation PNF 2: Flexion / abduction / external rotation to extension / adduction / internal rotation These movements can be performed in either…
Shoulder Horizontal Abduction / Adduction

These movements can be performed in either the lying or seated positions. There are currently no standard examination positions for horizontal abduction and adduction of the shoulder. During the movements of the gleno-humeral joint there are always relative movements within the scapulo-thoracic junction. These are usually described as fitting a set of established normalpatterns. These must be considered when…
Internal / External Rotation

Internal and external rotation of the knee is a popular test especially in ski-ing populations. The popliteus and hamstrings muscles play a significant role in rotating the knee (internally and externally) to aid unlocking and locking the knee. It should be noted that this position stretches the ligaments at t the rear of the knee…
Knee Flexion / Extension

Until the late 1970s 75% of all isokinetic use and research was based on a single joint system – the knee. With more recent progress in rehabilitation and knee surgery this trend no longer exists. The basic design of isokinetic dynamometers (except for special purpose units) has not changed since the original instrumentation became available…
This is how it all started…

In May 2000 isokinetics.net launched the first isokinetic web pages not made to sell you something. I had already worked with patients on the largest manufacturers machines (Cybex, Biodex and Kin-Com) but found their web sites contained little information on actually using isokinetics machines. Cybex and Biodex did run training courses, and had manuals to…
