The purpose of this study was to examine changes in peak torque of the knee extensor muscles for a group of subjects. In each of three sessions, six maximal isokinetic contractions (trials) were elicited from 12 men and 4 women without isokinetic testing experience. No significant differences occurred over sessions and trials, but there was a significant interaction effect. Significant quadrati...

CONTEXT The use of isokinetic dynamometers playing an important role in different settings of sports and medicine. Therefore, a high reliability of these devices is required. OBJECTIVE The aim of this study was to examine the inter-session reliability of the dynamometer BTE PrimusRS regarding to the isolated single-joint exercises extension / flexion of the knee and elbow for isokinetic testi...

OBJECTIVE The aim of this study was to assess the performance of prediction rules meant for declaration of efforts as being maximal or not during isokinetic strength testing in a cohort that underwent anterior cruciate ligament reconstruction. DESIGN Thirty-six individuals performed four sets of six reciprocal concentric knee extension/flexion repetitions at a testing speed of 60 degrees per ...

The patient was a 25-year-old (height: 183 cm, weight: 86 kg) professional rugby league winger. He had suffered a recurrent episode of a left hamstring (biceps femoris) injury at a training drill late in the season (Day 0). This occurred suddenly while changing direction at pace. The player felt the degree of pain when injured to be very similar to his previous episode earlier in the season, wh...

OBJECTIVES To determine the test-retest reliability and minimum detectable change scores for seven common clinical measurements of muscle strength and physical function in a multiethnic sample of sarcopenic, malnourished men and women. DESIGN Each participant visited the laboratory seven times over 25 to 26 weeks. Reliability was assessed for each measurement from Familiarization 1 to Familia...

BACKGROUND Fall-related injuries associated with aging are a serious clinical and economic problem. The Flo-Dynamics Movement System (FDMS), which consists of eight movements with a water-filled device, may be a useful low-impact exercise suited for older persons. This study investigated the effects of the FDMS regimen with the Wun-Jo trainer on measures of strength, flexibility, and balance in...

BACKGROUND The purpose of this study was to report on ankle and foot functions via the holistic evaluations using clinical examination, functional scores assessment and isokinetic tests after harvesting autogenous peroneus longus tendons for anterior cruciate ligament (ACL) reconstruction focusing on the donor site morbidity with a minimum 1-year follow-up period. MATERIAL AND METHOD The stud...

Prevention of infection, as well as bone covering and healing, is paramount in the management of limb injury with associated muscle injury. Volumetric muscle loss (VML) is the traumatic or surgical loss of skeletal muscle with resultant functional impairment. No standardized evaluation protocol exists for the characterization and quantification of VML. Clinical photographs and video recordings,...
