Biomechanical characterisation of leg movement during the golf swing following knee surgery (2012)

Abstract:

INTRODUCTION The forces transmitted through the knee throughout the golf swing have been found to be as high as those associated with running (Colwell et al., 2005) therefore playing golf with a knee that has undergone surgery may place extra stress on the previously damaged area leading to variances in the golf swing. While it has been established whether it is safe to return to golf after knee surgery (Jackson et al., 2009), the actual effect that knee surgery has on golf movement has as not been researched adequately. The aim of the current study was to characterise knee kinematics for previously knee injured and non injured subjects during the golf swing to ascertain any residual differences in movement, despite full clinical rehabilitation of injured subjects. METHODS 10 previously injured recreational golfers (SURGICAL) (5 female, 5 male, 17.0 ± 5.5 handicap) and 5 control non-injured recreational golfers (CONTROL) (3 female, 2 male, 21.8 ± 2.3 handicap) were recruited. Previo...

Abstract:

BACKGROUND Biomechanical computers models to date have not reported in detail how the models are validated and applied. The aim of the current study was to develop a biofidelic full-body musculoskeletal computer model to characterise knee kinematics and predict in-vivo knee kinetics. The underlying kinetics following knee surgery were studied to ascertain any residual differences in movement, despite full clinical rehabilitation of injured subjects. METHODS 10 previously injured recreational golfers (SURGICAL) (5 female, 5 male) and 5 control non-injured recreational golfers (CONTROL) (3 female, 2 male) each performed 8 double-leg squats and also 8 golf swings with their own driver in an indoor biomechanics facility. The previously injured subjects had all undergone left (lead) knee surgery for either ACL reconstruction or total Knee Replacement (TKR) more than six months prior to testing. Retro-reflective markers were tracked at 400 Hz by a 6-camera 3D motion analysis system. 3D ma...

Dynamic knee joint mechanics after anterior cruciate ligament reconstruction (2015)

Breen, Sarah; Kenny, Ian C.; Harrison, Andrew J.

Abstract:

Purpose: There is a scarcity of information on the long term adaptations in lower limb biomechanics during game specific movements after an anterior cruciate ligament (ACL) reconstruction. Particularly, variables such as knee abduction moments and transverse plane knee motion have not been studied during a game specific landing and cutting task after ACL reconstruction. The purpose of this study was to compare the hip and knee mechanics between the ACL reconstructed (ACLr) group and a healthy control group. Methods: 38 athletes (18 ACLr, 18 control) participated in the study. Three dimensional hip, knee and ankle angles were calculated during a maximal drop jump land from a 0.30 m box and unanticipated cutting task at 45°. Results: During the landing phase ACLr participants had increased hip flexion (p <0.003) and transverse plane knee range of motion (p = 0.027). During the cutting phase, ACLr participant’s previously injured limb had increased internal knee abduction moment com...

Hip rotation range of motion and its impact on lower limb alignment on landing (2010)

Hip rotation range of motion and its impact on lower limb alignment on landing (2010)

Breen, Sarah; Harrison, Andrew J.; Kenny, Ian C.

Abstract:

The purpose of the present study was to compare lower limb alignment at initial ground contact between groups with normal and abnormal hip rotation range of motion. Male (n=8) and female (n=8) subjects performed an maximal drop jump diagonal side cut task ten to the left and ten to the right. Lower limb alignment was assessed through knee angle, hip angle, ankle angle, thigh rotation and shank rotation at initial foot contact. One significant difference was reported between groups for the knee angle variable on the non dominant side. This indicates that the only the knee angle variable is affected by unbalanced hip rotation range of motion and on the non-dominant side.

Joint kinematics of landing in ACL rehabilitated volunteers (2011)

Joint kinematics of landing in ACL rehabilitated volunteers (2011)

Breen, Sarah; Harrison, Andrew J.; Kenny, Ian C.

Abstract:

The purpose of the present study was to compare the variability of movement and force production in ACL rehabilitated volunteers during landing from a maximal drop jump. Male (n=6) and female (n=7) volunteers with previous ACL reconstruction and rehabilitation performed a maximal drop jump diagonal side cut task (x20 trials). Knee and hip joint kinematics in all three planes were calculated during the landing component of the task. The range of motion (ROM) of the hip and knee joint, showed differences between the legs. The previously injured leg showed smaller ROM in hip and knee abadduction and knee flexion extension. The decreased range of motion in the previously injured leg may be indicative of a less variable landing movement repertoire, which may increase injury risk.

Lower limb kinematics, kinetics and coordination during a land and cut task; the role of gender and previous ACL injury (2012)

Breen, Sarah

Abstract:

Anterior cruciate ligament (ACL) injury continues to be a constant adversary to field sports athletes. Females are widely acknowledged as being at an increased risk of ACL injury, in comparison to males. Athletes who are successful in rehabilitation after surgery and return to their sport are reported to have an increased risk of repeated ACL injury and the development of osteoarthritis. The current thesis utilised a novel, maximal drop-jump land and unanticipated cutting task to assess the lower limb biomechanics of uninjured male and females, and previously ACL injured subjects (ACLr). Discrete measures of lower limb kinematics and kinetics were firstly compared between uninjured males and females, and secondly between the previously injured (PI) leg of ACLr subjects and both the contralateral non-injured (NI) leg and an uninjured subject’s control leg. The results show that females had increased hip internal rotation, the PI leg was not significantly different to the NI leg but w...

The development of a new protocol to assess performance measure in sports (2012)

Abstract:

The purpose of this study was to develop a novel protocol to be used in assessing performance outcomes in projectile sports. This study also wanted to establish if variability within a movement pattern (throwing) is detrimental to the outcome of that skill and to assess the validity of current methods used to measure performance. Single subject analysis was undertaken as 4 Wilson Trainer tennis balls were launched using a Tennis Cube launcher at a wall 25 times each. Infra-red light gate technique (wall mounted Optojump) in which ball tracking co-ordinates were obtained were compared to traditional movement measure device (3D Motion Analysis Corporation) coordinates. Agreement between the 3D landing point X and Y coordinates and the Optojump landing points X and Y coordinates were analysed using the Bland- Altman method.
