Background: The cachexia-anorexia syndrome impacts on patients' physical independence and quality of life. New treatments are required and need to be evaluated using acceptable and reliable outcome measures, e.g. the assessment of muscle function. The aims of this study were to:
Methods: The test consisted of 25 repetitions of isokinetic knee flexion and extension at maximal effort while seated on a Cybex NORM dynamometer. Strength and endurance for the quadriceps and hamstrings were assessed as peak torque and total work and an endurance ratio respectively.
Thirteen patients and 26 volunteers completed the test on three separate visits. Acceptability was assessed by questionnaire, reliability by intraclass correlation coefficients (ICC) and tests of difference compared outcomes between and within groups.
Results: All subjects found the test acceptable. Peak torque and work done were reliable measures (ICC >0.80), but the endurance ratio was not. Muscle function did not differ significantly between the patient and a matched volunteer group or in either group when repeated after one month.
Conclusion: For patients with non-small cell lung cancer or mesothelioma, the Cybex NORM dynamometer provides an acceptable and reliable method of assessing muscle strength and work done. Muscle function appears to be relatively well preserved in this group and it appears feasible to explore interventions which aim to maintain or even improve this.

The main aimof this study was to examine the absolute and relative reliability of some commonly used strength imbalance indices such as concentric hamstring-toconcentric quadriceps ratio, eccentric hamstring-to-concentric quadriceps ratio and bilateral concentric and eccentric strength ratios. An additional aim was to examine the reliability of the peak torque and work of the knee extensor and flexor muscles measured using the Cybex NORM dynamometer. Eighteen physically active healthy subjects (mean ± standard deviation, age 23 ± 3 years, height 176 ± 5 cm, body mass 74 ± 8 kg) were tested three times with 96 h between sessions. Peak torque, average work, unilateral and bilateral ratios were determined at 60, 120, 180 and )60 s)1. Low (0Æ34) to moderate (0Æ87) relative reliability (intraclass correlation coefficient, ICC) was found for strength imbalance ratios with eccentric hamstringto-concentric quadriceps ratio showing the greater ICC (>0Æ80). High ICC values (0Æ90–0Æ98) were found for peak torque and average work. Absolute reliability (standard error of measurement) ranged from 3Æ2% to 8Æ7% for strength imbalance ratios and from 4Æ3% to 7Æ7% for peak torque and average work measurements. This study established the reliability of the most common strength imbalance ratios and of absolute isokinetic muscle strength assessed using the Cybex NORM.

Σκοπός:
Η σπουδαιότητα του CYBEX NORM 770, στην λειτουργική αποκατάσταση της δύσκαμπτης άρθρωσης του γόνατος
Υλικό – Μέθοδος
22 ασθενείς με μετεγχειρητική δυσκαμψία γόνατος εκ των οποίων 15 άνδρες και 7 γυναίκες ηλικίας: από 12 ετών έως 60 ετών. Μέσος όρος ηλικίας: 31 έτη. Το εύρος της κίνησής τους κυμαινόταν από 0 – 0 – 10 έως 0 – 0 – 65 μοίρες και όλοι είχαν χειρουργηθεί. Όλοι δε προσήλθαν και υποβλήθηκαν στη διαδικασία κινητοποίησης με το Cybex Norm cpm 770, μετεγχειρητικά 2 12 μήνες αργότερα και μάλιστα όταν το πρόγραμμα κινητοποίησης το οποίο είχαν ακολουθήσει μέχρι τότε είχε αποτύχει.
