The frequency of golf injuries.

Although golf has not been recognized as a sport associated with injuries, epidemiologic studies document that back and elbow injuries are most common in male amateur golfers. Lower back and wrist injuries occur in the male golf professional while female professional golfers are more likely to suffer injuries to the wrist and lower back, respectively. The elbow, followed by the lower back, is the most likely area of injury associated with female amateur golfers. These injuries are related to overuse, poor conditioning, and improper swing mechanics. It is the hope of this author that more studies regarding the mechanics, prevention, and treatment of these injuries will be stimulated by this journal and others.

Prevention and treatment of elbow injuries in golf.

Golf interest is on the increase, resulting in a corresponding increase in golf-related tendon injuries. Injuries are best avoided by a good strength and flexibility program, proper warm-up exercises, and good stroke mechanics. Treatment is directed toward restoring the integrity of the muscle/tendon unit at the elbow and preventing recurrences.

Golf for the senior player.

In no other sport does the senior player enjoy as much opportunity to participate and compete at various skill levels as in golf. No other sport encourages as much mixed competition. Because of their spending power, equipment and travel packages are often geared to the senior player. Advancing medical technology and specialized instruction effectively combat the physical effects of aging. These and other factors will ensure the continued popularity of the game of golf.

[Traumatic thrombosis of the distal ulnar artery (hypothenar hammer syndrome) in a golf player with an accessory muscle loop around Guyon's canal. Case report].

Arteriography of a 34-year-old golf player with M. Raynaud symptoms of his left hand revealed filling defects in the digital arteries II to IV fingers associated with corkscrew-like configuration of the ulnar artery in Guyon's space. The preoperative workup including 50 clinical laboratory tests searching for connective tissue diseases, vasculitis, and haematological disorders was without pathological findings; more central embolic sources were excluded angio- and cardiologically. MRI-scan demonstrated an anomalous muscle at the level of the hamate hook located underneath the M. palmaris brevis forming a sling around the ulnar artery. Surgery showed the ulnar artery distal to the anomalous muscle dilated with fibrotic thickening and intraluminal thrombosis. The involved A. ulnaris segment was resected and an interpositional vein graft performed. Histopathologic sections showed fibrosis of the arterial wall with intraluminal thrombosis and elastica fragmentation indicating traumatic genesis (hypothenar-hammer syndrome). We suspect intensive golf playing with the grip style and repetitive movements leading to pressure injury of the hypothenar area and the underlying ulnar artery. Contraction of the anomalous muscle belly may have additionally compressed the artery slowing down the arterial flow and accelerating the thrombosis.

Investigation of the candidate genes ACTHR and golf for bipolar illness by the transmission/disequilibrium test.

Several versions of the transmission/disequilibrium test (TDT) were applied to the two candidate genes ACTHR and Golf for bipolar illness. Analyses were carried out separately for paternal and maternal transmission. Evidence for linkage and association was found for ACTHR for paternal transmission in support of a parent-of-origin effect. Possible evidence for segregation distortion was found for one of the two markers for Golf for maternal transmission.

[Echogenic intracardiac structures (golf ball phenomenon) as predictors of chromosome anomalies].

UNLABELLED: Small echogenic areas in the fetal heart are known as the golf ball phenomenon. These structures are considered by some to be a marker for chromosomal anomalies. AIM: To prospectively study the relationship of echogenic intracardiac structures and chromosomal aberrations. METHODS: Over a 15 month period (6/96-9/97) 4500 unselected fetuses between 16-31 weeks were screened for malformations; in each case echogenic intracardiac structures were sought. RESULTS: In 77 cases (1.17%) single or multiple echogenic punctate intracardiac structures could be diagnosed. In 60 fetuses (78%) chromosome analysis was performed. Two (3.3%) had chromosomal abnormalities--trisomy 21 and 45.XO/46.XX. CONCLUSION: The golf ball phenomenon appears to be a normal variation in the development of the papillary muscle. This sign is usually easily to identify and if present, should lead to a more detailed screening for anomalies. In the case of other sonographic abnormalities, with advanced maternal age or with a positive triple test, a chromosomal analysis should be performed.

Sorption and mobility of dithiopyr in golf course greens rooting medium.

Sorption and mobility of dithiopyr in golf course greens rooting medium (RM) were studied. The sorption increased from 20 to 27 degrees C at 24 h after treatment (HAT) and reached equilibrium in 48 HAT at 20 degrees C. The sorption isotherms had Freundlich values (KF) of 1122, 27.44 to 35.16, and 0.053 to 0.168 for peat moss, the RM, and quartz sand, respectively, and solid to aqueous phase partition coefficients (Kd) of 470 to 1706 L/kg, 14.61 to 84.4 L/kg, and 0.07 to 0.29 L/kg for peat moss, RM, and quartz sand, respectively. Generally, higher dithiopyr concentration in the aqueous solution and the reduced pH of the solution corresponded to the higher Kd values. The average values for dispersion (D, cm2/min), retardation coefficient (R), beta, and omega parameters for solute transport in the RM lysimeter; obtained from CXTFIT curve fitting of Br- breakthrough curves; were 0.95, 1.01, 1, and 93.89, respectively. After elutriation by 18 L of aqueous KNO3 (10 mM), greater than 90% of the added dithiopyr remained in the top 10 cm of the RM lysimeter and no detectable dithiopyr was present at depths beyond 35 cm. The lysimeter effluent contained dithiopyr at concentrations less than 3.5 microg/L. The R value obtained from CXFIT curve fitting is 38.5. Results from both sorption and mobility experiments indicated that dithiopyr is quite immobile in golf course greens RM and has minimal potential for movement into surface water drainage or ground water.

Total hip arthroplasty using the Wroblewski golf ball cup inserted through the posterior approach. A high rate of dislocation.

The Wroblewski golf ball acetabular cup was introduced by surgeons using the trochanteric osteotomy approach for revision total hip replacement (THR) in order to reduce the rate of dislocation. We have routinely used the Ogee long posterior wall (Ogee LPW) and the Wroblewski angle bore cups in THR. Although the new Wroblewski golf ball cup performed well there was a significant early rate of dislocation of 20%. Our rate of dislocation over a period of ten years using the Ogee LPW and Wroblewski angle bore cups had been 0.52%. We present our findings and an investigation as to why the new cup has such a high rate of dislocation when used with the posterior approach. We show that a relatively small change in the design of the acetabular component resulted in significant adverse clinical results.

[Trendy sport: golf].

Golf is currently the most frequently played sport in the world and it will continue to grow in importance. Nevertheless, there is a striking deficit in our knowledge of the physical and psychological profile of golfers. In the foreground are not the acute but the chronic sport specific injuries, predominantly of the lumbar spine, the upper extremities (golfer's elbow and golfer's shoulder), and less commonly of the lower limbs (minor injuries to the ligaments). In addition to therapy, prophylaxis should also be used in order to better recognise and influence the sport specific burdens.

The analysis of golf swing as a kinematic chain using dual Euler angle algorithm.

The manner in which anatomical rotation from an individual segment contributes to the position and velocity of the endpoint can be informative in the arena of many athletic events whose goals are to attain the maximal velocity of the most distal segment. This study presents a new method of velocity analysis using dual Euler angles and its application in studying rotational contribution from upper extremity segments to club head speed during a golf swing. Dual Euler angle describes 3D movement as a series of ordered screw motions about each orthogonal axis in a streamlined matrix form-the dual transformation matrix- and allows the translation and rotation component to be described in the same moving frame. Applying this method in biomechanics is a novel idea and the authors have previously applied the methodology to clinical studies on its use in displacement analysis. The focus of this paper is velocity analysis and applications in sports biomechanics. In this study, electrogoniometers (Biometrics, UK) with a frequency of 1000 Hz were attached to a subject during the execution of the swing to obtain the joint angles throughout the motion. The velocity of the club head was then analyzed using the dual velocity which specifies the velocity distribution of a rigid body in screw motion at any point in time as the dual vector. The contributions of each segment to the club-head velocity were also compared. In order to evaluate this method, the calculated position and velocity of the club head were compared to the values obtained from video image analysis. The results indicated that there is good agreement between calculated values and video data, suggesting the suitability of using the Dual Euler method in analyzing a kinematic chain motion.

Stress fracture of the sternum in a golf player.

A case report is presented of a stress fracture of the sternum in a golf player occurring some weeks after modifying training habits. An ultrasound screening test was used successfully and the diagnosis confirmed with a positive technetium bone scan. The patient had explorative surgery elsewhere. This case is compared to another case described in 1987 by Keating in a wrestler.

The efficacy of video feedback for learning the golf swing.

This study was designed to examine the efficacy of video instruction relative to that of verbal and self-guided instruction. Before training, 30 golfers were assigned at random to one of three groups: video, verbal or self-guided instruction. Video instruction was defined as a practice session in which the teacher was aided by the use of video. Verbal instruction was defined as practising with the teacher providing verbal feedback. Self-guided practice was defined as practising without the aid of a teacher. The participants had a pre-test, four 90 min practice sessions, an immediate post-test and a 2 week delayed post-test. During the pre-test and post-tests, all participants were required to strike 15 golf balls, with a 7-iron, from an artificial turf mat for distance and accuracy. The results showed that all groups were equal on the pre-test. On the first post-test, the two instruction groups performed worse than the self-guided group. However, on the second post-test, the two instruction groups performed better than the self-guided group, with the video group performing best. We interpret these results to mean that video analysis is an effective means of practice, but that the positive effects may take some time to develop.

Analytical design of iron golf club heads.

This paper describes an analytical method for the design of iron golf club heads. The method divides the club head into the basic shape and the back-weighting. The basic shape, which consists of the club face profile, hosel and club face-hosel blend section, is configured directly from geometric specifications. An adaptive random search optimization algorithm is employed to design the back-weighting to obtain desired mass properties for the club head. The designer has control of the general configuration of the back-weighting through the method of geometric influencing. Several dynamically equivalent iron club heads are presented that were designed using this method.

Hip and shoulder rotations during the golf swing of sub-10 handicap players.

The motion of the shoulders, arms and club during the golf swing has often been explained using the 'double pendulum' model. Despite subsequent explanations for the actions of the distal segments of the body, the coordination of more proximal segments during the swing is less well understood. To ascertain the pattern of centre of mass motion and hip and shoulder rotations that result in a high clubhead speed at impact, the swing used in driving from the tee of eight low-handicap golfers was videotaped and analysed using three-dimensional techniques. The shoulders rotated in excess of 90 degrees during the backswing and, in 75% of the golfers, continued rotating away from the flag as the hips began turning back towards it. This sequential pattern of hip and shoulder rotation indicated that they conformed to the 'summation of speed' principle, which is hypothesized to result in a greater torque being applied to the club before impact. The speed of the drive was also benefited by the centre of mass shifting exclusively in the intended direction of ball flight during impact.

Applying bandwidth feedback scheduling to a golf shot.

Bandwidth knowledge of results (KR) involves the presentation of precise error KR only on those trials in which a preset criterion of accuracy is not met. When the criterion is met, only a general statement referring to this success is given. It has been shown that bandwidth KR increases movement consistency relative to 100% relative frequency KR (Lee & Carnahan, 1990). While this and other KR schedules have been successful in promoting motor learning, there has been no attempt to generalize this finding to a motor task requiring whole-body coordination. This study examined whether, by using information feedback suited to a complex task (Kernodle & Carlton, 1992), the findings relating to bandwidth feedback would transfer to such a task. Participants practiced a golf chipping task with either KR or error correcting transitional information, under 0, 5, or 10% bandwidth conditions. Participants in the 10% bandwidth condition who had received transitional information performed more consistently in retention than all other participants. This result provides support for the generalization of bandwidth feedback principles to complex tasks.

The learning advantages of an external focus of attention in golf.

This study examined whether the learning advantages of an external focus of attention relative to an internal focus, as demonstrated by Wulf, Höss, and Prinz (1998), would also be found for a sport skill under field-like conditions. Participants (9 women, 13 men; age range: 21-29 years) without experience in golf were required to practice pitch shots. The practice phase consisted of 80 practice trials. One group was instructed to focus on the arm swing (internal focus), whereas another group was instructed to focus on the club swing (external focus). One day after practice, a retention test of 30 trials without instructions was performed. The external-focus condition was more effective for performance during both practice and retention.

Attention and performance in miniature golf across the life span.

Highly skilled adolescent (15-19 years), young (25-35 years), middle-aged (50-57 years), and older (58-73 years) miniature golf players were examined in training and competitive conditions. Number of shots, heart rate, ratings of anxiety, and concentration time were registered. IN addition, two attentional subscales from the Test of Attentional and Interpersonal Style (TAIS) inventory (Nideffer, 1976) were administered. Results indicated (a) parallel increases of heart rate and rated anxiety in competition for all age groups, (b) improvement of motor performance in competition for adolescent and young-adult players, and deterioration of motor performance in competition for middle-aged and older players, and (c) increased concentration time for the two younger samples, and decreased concentration time for the two older samples in competition. As well, the TAIS data indicated greater self-perceived external and internal distractability in the two older, compared to the two younger samples. This age-related vulnerability to distractions was shown to partly mediate age differences in competitive motor performance. The overall pattern of outcome is discussed relative to the view that the adult aging process is associated with a deficit in the ability to handle situations of high arousal due to age-related deficits in a variety of basic cognitive capacities.

Golf club shaft impalement: case report of a zone III neck injury.

Impalement occurs when a portion of the body is penetrated by a rigid object. These injuries incorporate aspects of both blunt and penetrating type injuries in that the object or the body at time of impact is traveling at relatively low velocity and the energy is dissipated over a short distance. Impalement injuries have been described for most body cavities. Evaluation of these injuries can be uniquely challenging. We present a case of impalement of the neck from an object previously unreported in the literature, a golf club shaft.
