ICC values of 0. Thirty-two older adults Limit Results 25 50 Although there have already been single studies on this topic for the IsoMed concerning maximum strength measurements, there has been no study regarding the assessment of strength-endurance so far. Isokinetics and Exercise Science.

However, 22000 to a systematic practice-based improvement found for eccentric measurements, we suggest to do a familiarisation session prior the actual testing sessions in practice.


In order for an isokinetic device to be clinically useful, the reliability of specific applications must be established. The dose calibrator uses a gas filled chute ionization chamber as a detector system. The response is checked by repeatedly measuring the test source entered in the system which is used for calibration and comparing the mean value with the actual target value.

However, to date, only a few studies have concentrated on multi-joint MJ leg strength measurements. Abstract This study investigated the effect of a week recreational skiing intervention on lower limb muscle strength and cardiorespiratory fitness in participants with unilateral total knee arthroplasty TKA.

The mini-PC is available as a small desktop-PC or as a microtower and is mainly used in those locations where it is possible to build in the system, for example behind the cover of a hot cell or below a work bench. Nuclide and activity of the test source, however, are freely selectable. The deviation and the maximum spread between the individual measured values are displayed.


However, even years after TKA, quadriceps muscle strength is still impaired leading to a consistent side-to-side asymmetry in subjects with unilateral TKA Maffiuletti et al. There is evidence that these increases might reduce the side-to-side asymmetry in strength, at least in more complex isokinetic movements.

Although, the skiing intervention affected the CSA of RF in both legs quadriceps muscle strength increased exclusively in the involved leg suggesting that most adaptations enabling strength gains were neural. This study is the first to investigate reproducibility for MJ leg strength measurements using the IsoMed system, which recently was introduced into the market. Thirty four physically active male subjects mean age: The standard measuring chamber type is calibrated for all radionuclides used in nuclear medicine and radio pharmacy.

Abstract Systematic assessment of muscle strength of the lower extremities throughout the annual training cycle in athletes is crucial from a performance perspective for the optimization of the training process, as well as a health perspective with regard to injury prevention.

Locomotion Laboratory

Abstract The purpose of this study was to determine relative as well as absolute reproducibility for the IsoMed dynamometer in measuring Peak Torque PT during concentric and eccentric maximum knee extension at two angular velocities. If this process is carried out manually, there is a relatively high radiation exposure risk of the lab staff. A high BFD was evident in the eccentric mode in both groups highlighting isomef need for 20000 strengthening.

The program is designed for the administration of both preparations and ready-to-use radiopharmaceuticals. The software documents the production process of the radioactive medications in compliance with GMP, including all necessary additives, records the production and documents the application in the patient.


The influencing factors for containers e.

Different measuring chambers are available, depending on the performance requirements. An essential factor for radiation exposure which may occur, for example, in the hot laboratory of a PET-CT system, is the process of drawing up the PET activity from the delivered supply container e.

Isomed introduction

Thirty five physically active male subjects mean age: Dose Calibrator Product description Versions Types of measuring chambers. In addition to the above mentioned complete systems, we also offer a basic module consisting of measuring chamber and ISOMED program. The intervention group skied three times a week whereas the control did not change their daily routines over a period of 3 months.

However, the results of individual evaluation show that the BFD was more frequent in the NT in most measurements. Above all, the long-term quality and user-friendliness of the predecessor models served as a basis for the current model. Further nuclides can be added. Reproducibility for isometric and isokinetic maximum knee flexion and extension measurements using the IsoMed dynamometer.

Detection of systematic errors was performed using paired sample t-tests, relative and absolute reliability were examined using intraclass correlation coefficient ICC 2. Other PC systems possible on request e. Top a Test source A test source to is needed to determine the response for the quality control to be carried out regularly DIN Home – Forschung – Publikationen.

We recommend using a long-lived Cs test source with approx.
