“…We identified hip joint centres by fitting a sphere to the motion of thigh markers, while knee joint flexion-extension axes were identified using the mean helical axis method described by Besier and colleagues. 14,16 Raw 3D coordinate data were filtered using a zero-lag fourth-order low-pass Butterworth filter with a cut-off frequency of 8 Hz as determined through residual analysis. 17 We used the filtered marker trajectories to compute 3D segment and joint angles using the Euler angle method in conjunction with BodyBuilder software, version 3.6 (Vicon, OxfordMetrics).…”

Purpose: To determine the kinematic parameters that characterize good and poor single-leg squat (SLS) performance. Methods: A total of 22 healthy young adults free from musculoskeletal impairment were recruited for testing. For each SLS, both two-dimensional video and three-dimensional motion analysis data were collected. Pelvis, hip, and knee angles were calculated using a reliable and validated lower-limb (LL) biomechanical model. Two-dimensional video clips of SLSs were blindly assessed in random order by eight musculoskeletal physiotherapists using a 10-point ordinal scale. To facilitate between-group comparisons, SLS performances were stratified by tertiles corresponding to poor, intermediate, and good SLS performance. Results: Mean ratings of SLS performance assessed by physiotherapists were 8.3 (SD 0.5), 6.8 (SD 0.7), and 4.0 (SD 0.8) for good, intermediate, and poor squats, respectively. Three-dimensional analysis revealed that people whose SLS performance was assessed as poor exhibited increased hip adduction, reduced knee flexion, and increased medio-lateral displacement of the knee joint centre compared to those whose SLS performance was assessed as good (p a 0.05). Conclusions: Overall, poor SLS performance is characterized by inadequate knee flexion and excessive frontal plane motion of the knee and hip. Future investigations of SLS performance should consider standardizing knee flexion angle to illuminate other influential kinematic parameters.Key Words: kinematics; knee joint; leg injuries; musculoskeletal physiological phonomena.

“…ISA theory has been extensively used in biomechanical analysis, particularly to determine the location and orientation of anatomical joints. This technique has been used in knee [18][19][20][21], shoulder [22][23][24] and elbow [25] joint kinematics and cervical joint whiplash diagnostics [26]. Therefore, literature has shown that ISA theory is an effective methodology to identify joint position and study segment rotation.…”

A number of recent studies have measured the extent and timing of segment rotation during the golf swing. A promising technique, instantaneous screw axis (ISA) theory, could provide a better expression of segment rotation. In Part 1 of this two-part study, the objectives are to identify the ISA of the pelvis, shoulders and left arm during the downswing, compute segment angular velocity relative to that segment's ISA and verify that ISA theory is a valid tool to analyse segment rotation during the golf swing. Results indicate that for all subjects, at least 71% of marker velocity is a result of rotation about their respective ISA, when averaging results over the duration of the downswing, confirming that motion is primarily rotational. Furthermore, ISA position and orientation of each segment approaches, on average, the expected gross axis of rotation, confirming that motion about the ISA is representative of joint motion.

“…tibiofibular and talocalcaneal, is very limited [8,11,25,47]. Nevertheless, the latter joint shows patterns of rotations similar to that of the tibiotalar here analysed [28], more hinge-like than those at the knee [11,13,39,57], but less than those at the elbow [49,50]. The extent to which the present use of the Burmester theory applies also to other human joints can follow in future studies.…”

“…All these methods have been used extensively to describe motion of the human lower limb joints [2-4, 19, 23, 25, 28, 32, 37, 54]. Despite the established multiaxial nature of the human joints, still a representative single axis of rotation is sought in the design of joint prostheses [18,22,27,49], and in prosthetics and orthotics [35,42,55].…”

In prosthetics and orthotics design, it is sometimes necessary to approximate the multiaxial motion of several human joints to a simple rotation about a single fixed axis. A new technique for the calculation of this axis is proposed, originally based on Burmester's theory. This was compared with traditional approaches based on the mean and finite helical axes. The three techniques were assessed by relevant optimal axis estimation in in vitro measurements of tibiotalar joint motion. A standard jig and radiostereometry were used in two anatomical specimens to obtain accurate measurements of joint flexion. The performance of each technique was determined by comparing the motion based on the resulting axis with the experimental data. Random noise with magnitude typically similar to that of the skin motion was also added to the measured motion. All three techniques performed well in identifying a single rotation axis for tibiotalar joint motion. Burmester's theory provides an additional method for human joint motion analysis, which is particularly robust when experimental data are considerably error affected.
