Isokinetic dynamometers, such as the Cybex and Mini-Gym, offer alternative measurements. Unfortunately the Cybex, though accurate, is very expensive and cumbersome, while the Mini-Gym though portable and cheap may lack preciseness. Elbow flexion, shoulder flexion, shoulder abduction, trunk extension,...
Isokinetic dynamometers measure joint torques about a single fixed rotational axis. Previous studies yet suggested that muscles produce both tangential and radial forces during a movement, so that the contact forces exerted to perform this movement are multidirectional. Then, isokinetic dynamometers might...
A Cybex II isokinetic dynamometer was used to measure dominant leg strength at 180掳/sec. One-way ANOVA revealed significant between group differences for absolute flexion and extension (Nm), extension/body weight (Nm/Kg), and extension/lean body weight (Nm/Kg). Scheffe post-hoc comparisons ...
and shoulder muscles Bas Habets1,2,3* , J. Bart Staal3,4, Marsha Tijssen1,4 and Robert van Cingel1,4 Abstract Objective: To determine the intrarater reliability of the Humac NORM isokinetic dynamometer for concentric and eccentric strength tests of knee and ...
To measure quadriceps and hamstring muscle strength with Isokinetic dynamometer in patients with patellofemoral pain syndrome (PFPS) and also to examine the relationship between muscle strength and functional test scores and subjective assessment. In this case-control study a total of 30 subjects (15 ...
Isokinetic muscle strength (average peak torque and average work per repetition) was measured on the same individuals using a Lido庐 isokinetic dynamometer.Results: Correlations between the strength measurement techniques were generally favorable with the lowest correlation being .72, (95 percent ...
The patient is installed on the seat of the isokinetic dynamometer. The trunk-thigh (hip) angle is set at 85°, the thigh-leg (knee) angle at 50° and the foot-leg (ankle) angle at 90°. In order to stabilise the position, the trunk, thigh and foot of the tested leg are ...
and other tennis and sport-specific movement patterns. One of the primary muscular imbalances found in the overhead athlete is in the shoulder. Extensive research usingisokinetic dynamometersto measure strength in elite tennis players has identified muscular imbalances between the shoulder internal and ...
The isokinetic dynamometer was calibrated according to the manufacturer's directions prior to the evaluation. The patients performed a warm up walk of 10 min before the evaluation. We evaluated the concentric torques of the knee at speeds of 60 degrees/s and 180 degrees/s. The evaluations were...
Two ways to objectively measure muscle strength are isokinetic dynamometers (IDs) and hand-held dynamometers (HHDs). While the psychometric properties of these devices have been investigated in different contexts using different models, joints and conditions, the resulting information is fragmented and ...
