“…Tsiganos et al [34] investigated knee joint positioning sense using an isokinetic dynamometer at 30°, 45° and 70° knee flexion. They reported that the mean error value at 30° knee flexion was statistically greater than the mean error value at 70° knee flexion [34].The starting position to reproduce the leg extension target angles was at 90° knee flexion. Hence, the participants might have moved their knees to reproduce 30° knee flexion more than for 45° and 60°.…”

PurposeThe study investigated the effects of FIFA 11+ and HarmoKnee, both being popular warm-up programs, on proprioception, and on the static and dynamic balance of professional male soccer players.MethodsUnder 21 year-old soccer players (n = 36) were divided randomly into 11+, HarmoKnee and control groups. The programs were performed for 2 months (24 sessions). Proprioception was measured bilaterally at 30°, 45° and 60° knee flexion using the Biodex Isokinetic Dynamometer. Static and dynamic balances were evaluated using the stork stand test and Star Excursion Balance Test (SEBT), respectively.ResultsThe proprioception error of dominant leg significantly decreased from pre- to post-test by 2.8% and 1.7% in the 11+ group at 45° and 60° knee flexion, compared to 3% and 2.1% in the HarmoKnee group. The largest joint positioning error was in the non-dominant leg at 30° knee flexion (mean error value = 5.047), (p<0.05). The static balance with the eyes opened increased in the 11+ by 10.9% and in the HarmoKnee by 6.1% (p<0.05). The static balance with eyes closed significantly increased in the 11+ by 12.4% and in the HarmoKnee by 17.6%. The results indicated that static balance was significantly higher in eyes opened compared to eyes closed (p = 0.000). Significant improvements in SEBT in the 11+ (12.4%) and HarmoKnee (17.6%) groups were also found.ConclusionBoth the 11+ and HarmoKnee programs were proven to be useful warm-up protocols in improving proprioception at 45° and 60° knee flexion as well as static and dynamic balance in professional male soccer players. Data from this research may be helpful in encouraging coaches or trainers to implement the two warm-up programs in their soccer teams.

“…During the experiments, subjects were blindfolded and wore headphones to rule out visual and audible clues [32], [33]. The mean joint positioning error of the three measurement degrees of error from the target position were recorded for analysis [34]. The lower mean error value indicated the better knee proprioception.…”

“…Finally, proprioception was tested at 3 separate angles. The joint position sense was tested at 45, 60 and 70 degrees (5,(11)(12)(13) of knee flexion. The patient was seated on the Biodex, similar to the one used before, and then the knee, at random order, was moved to 45 degrees from 90 degree flexion and kept in the same position for 5 seconds.…”

The anterior cruciate ligament (ACL) deficient knee has been subjected to various research and many conclusions have been drawn to the loss of function in relation to it. ACL reconstruction is also very commonly done as this ligament damage is the most common injury in sports. Muscle strength and proprioception have been postulated to be affected alongside this injury. We conducted a cross sectional study in 19 patients who have ruptured their ACL. We measured their muscle strength, thigh muscle bulk and proprioception in comparison to their contralateral normal knee. The Biodex Isokinetic machine was used to measure the muscle strength and proprioception. The thigh circumference was measured manually using a measuring tape. There was significant reduction of muscle strength and thigh circumference in the ACL deficient limb as compared to the normal side, p <0.05. The affected knee also showed reduction in proprioceptive ability at 70 degree angle (z score-2.17, p <0.05), but there was no significant reduction at the other angles. These findings are important as the data show that there is reduction in muscle strength and proprioceptive ability in an ACL deficient knee; hence, rehabilitation addressing these two areas should be emphasized pre-surgery.
