“…Considering the high physical activity level of our sample (pre-injury Tegner 7.4 ± 1.6) and the fact that nearly 50% of patients failed in one or more tests 6 months after surgery, BIA must be considered a very challenging return-to-sports test. Thus, our results confirm an earlier report to demonstrate that BIA is more conservative compared to commonly performed strength and hop tests [21]. The test associated with the greatest failure rate was the single-leg countermovement jump performed with the injured leg, at which 60 out of 245 subjects (24.5%) achieved "poor" or even "very poor" results.…”

Functional tests are used to facilitate return-to-sports decisions after anterior cruciate ligament reconstruction (ACLR). This study presents comprehensive physical fitness test data acquired in highly active patients within the first year after ACLR, for comparison between different grafts, age groups, and sexes. The outcomes from a specific seven-item test battery and isokinetic strength test data were extracted from a patient database. Results were compared to normative data from age-and sex-matched controls and between subgroups of patients. A total of 245 patients (94 women, 23.8 ± 8.4 years, pre-injury Tegner 7.4 ± 1.6) were tested 185 ± 44 days after surgery. In 116 patients (47.3%), one or more test results were classified as "poor" or "very poor" after comparison with normative data, with failures being most frequent during single-leg squat jump and plyometric strength tests. Test failures were more prevalent in adults than in adolescents <19 years (61.4%-62.2% vs. 24.5%, p < 0.001) and in men (61.6% vs. 24.5%, p < 0.001), but no differences were found between grafts. Isokinetic knee extensor strength was lower by 24.1% on the injured side. Six months after ACLR, nearly 50% of highly active patients presented with strength and functional fitness deficits. These deficits are particularly prevalent in older patients and men.

“…In addition, a comparison of the BiA test to standard hop tests and isokinetic knee dynamometry in patients after ACL reconstruction showed that the BiA test battery is more physically challenging than the standard hop and isokinetic strength test. There was a significantly greater RTS fail rate compared with standard testing batteries [30]. In order to achieve as distinct data as possible, this test battery seems to be a suitable measurement for evaluating knee function in athletes with a high risk of ACL injury.…”

Functional Knee Performance Differences in Handball are Depending on Playing Class

Handball is one of the most traumatic sports. The knee is the most commonly injured joint. To prevent knee injuries, optimal functional knee stability is of great importance. Nevertheless, there is still no consensus about objective criteria for knee function. Depending on playing class, injury rates seem to differ. The purpose of this study was to evaluate knee function in handball depending on playing class and to establish reference data for functional knee stability. 261 handball players (25.1±5.8 years) performed a functional test including two- and one-legged stability assessments, jump tests, speed and agility analysis. Except for balance, differences between playing classes were detected in all tests with superior performance of high-class players (Germany’s 1st (“Oberliga”) and 2nd (“Verbandsliga”) non-elite playing class). High-class players achieved significant better results in jumping height (p≤0.011–0.029), relative power per body weight in the two-legged counter movement jump (p≤0.023) and speed and agility tests (p≤0.001). This study illustrates the relevance of playing class specific screening. Sports and playing class-specific databases will help to identify individual deficits and strengths in order to prevent injury and increase performance. Moreover, objective criteria for return to sports can be established.

“…The present study explored the utility of smart technology (ViMove) and MatScan pressure sensing mat in assessing coronal plane alignment differences in the assessment of ACL reconstruction patients for return to sport assessment. Accelerometers have been utilised in assessment for return to sport post ACL reconstruction as demonstrated by Gokeler et al , where accelerometers were used to assess jump height and power output asymmetries with hop tests 18 19. We found differences in performance between groups and individuals.…”

“…Smart technology has the potential to change the way the clinician interacts with the patient through wearable inertial sensor technologies and influence postoperative recovery 17. It has recently been shown to be beneficial as part of a rehab assessment for ACL patients 18 19. ViMove (DorsaVi, East Melbourne, Australia) is one such device which incorporates the coordinates from an accelerometer and gyroscope into a user-friendly interface displaying lower limb alignment during functional activities.…”

IntroductionAnterior cruciate ligament reconstruction (ACLR) is associated with poor return to sport and high graft re-rupture rates. This study explored the use of a wearable inertial sensor (ViMove) that incorporates an accelerometer and gyroscope, and MatScan pressure sensing mat (TekScan, South Boston, Massachusetts, USA) to provide objective return-to-sport measures.MethodsThree cohorts’ ACLR patients, non-athletic controls and elite athletes (Australian seven’s rugby Olympic Gold medallist). Patients performed biometric and functional tests (thigh circumference and triple hop) and the ViMove knee module (consisting of single and double leg squats, hops and box drops) for lower limb alignment assessment, concurrently with force plate.ResultsElite athletes had less varus/valgus (VV) movement during ViMove exercises compared with the ACLR cohort, who in turn had less VV malalignment than controls. When analysing side-to-side differences, single leg squats and box drop were asymmetrical in the ACL group, with greater malalignment in the reconstructed leg (p<0.05). Subgroup analysis failed to differentiate who passed or failed current return to sport assessment. TekScan pressure plate detected differences in double leg landing and flight time while hopping not detected with ViMove, suggesting ACL patients compensate by offloading the reconstructed leg to improve coronal alignment during double leg activity.ConclusionThe inertial sensor detected differences in motion for patients following ACLR, which are known to be associated with graft rupture and were not detected with functional return to sport testing. Coupling the device with data from a pressure plate provides a powerful assessment tool detecting alignment differences known to be associate with graft failure only previously detected in formal gait analysis.
