Knoop, M, Fernandez-Fernandez, J, and Ferrauti, A. Evaluation of a specific reaction and action speed test for the soccer goalkeeper. J Strength Cond Res 27(8): 2141‐2148, 2013— The aim of this study was to develop and evaluate a new test for the soccer goalkeeper that involved perceptual and movement response components (i.e., sprint running, jumping, diving, and direction changing). The evaluation consisted of measurements in different age (U19 [18.0 6 0.9 years], n = 21; U14 [14.1 6 0.3 years], n = 13) and performance (i.e., first goalkeepers and substitutes) groups of goalkeepers, including measures of test-retest reliability. Validity was assessed comparing the 2 groups of goalkeepers with different expertise levels (i.e., competitive level and age group). The test-retest correlations of the reaction and action speed (RAS) test performance were significant in all single (intraclass correlation coefficient [ICC] = 0.68‐0.95; p , 0.01) and complex measurements (ICC = 0.91; p , 0.01). The RAS single test performance was higher in older (U19) compared with in younger (U14) players (p , 0.001), and they also showed better results in the RAS complex tests (p = 0.000), being significantly different between the first goalkeepers and their substitutes (p = 0.001). Moreover, for all age groups (i.e., U14, U19), defensive actions to the bottom corners were faster than those to the top corners, with large ES (i.e., . 1). The major findings of the study were that the RAS test provided a reliable and valid method of assessing specific defensive agility in a group of youth soccer goalkeepers. Performance responses during the RAS test allow coaches to discriminate between age-matched goalkeepers, identify weaknesses (e.g., nonpreferred side dive performance), and to design specific training tasks.

Evaluation of a specific reaction and action speed test for the soccer goalkeeper.

The English literature reports a mere handful of cases involving simultaneous dislocation of two joints in the same finger. To our knowledge, all cases reported to date have been in skeletally mature individuals. We report a case of simultaneous proximal interphalangeal (PIP) and distal interphalangeal (DIP) joints dislocations in one finger in a 14-year-old rugby player, managed by closed reduction and early mobilization, with excellent outcome.

Simultaneous double interphalangeal joints dislocation in a finger in a teenager.

Background
Simultaneous dislocation of the proximal and distal interphalangeal joints of the same finger is a rare event. In literature simultaneous double interphalangeal dislocation in the same finger has been reported only one case in a skeletally immature patient which was a fourteen year old male. Our case was twelve years old which is the youngest case in the literature that has been reported.

We present a case with irreducible simultaneous dislocation of both the distal interphalangeal (DIP) and proximal interphalangeal (PIP) joints in the little finger. A combination of the delay from injury to closed reduction and the entrapped flexor digitorum profundus (FDP) tendon at the PIP joint prevented closed reduction from being performed. To our knowledge, this is the first report of such a condition.

Irreducible simultaneous dislocation of both interphalangeal joints in the little finger: a case report.

Background Long-term damage in the hip, knee and ankle joints of football players has been thoroughly discussed in the literature. Compared with outfield players, however, goalkeepers sustain injuries to the upper extremities five times more often. There is a lack of studies on long-term functional damage to the wrist and finger joints of football goalkeepers. Hypothesis Repetitive micro-traumas and injuries lead to degenerative diseases in goalkeepers after 20 years of playing recreational soccer. Methods The personal histories, injury histories and clinical examination findings of the wrist and finger joints of 27 goalkeepers were compared with the findings obtained in a control group of outfield players. Results Goalkeepers were significantly more restricted in finger movement (p  Conclusion Medical history and clinical findings indicate deficits in the hands of soccer goalkeepers and a high prevalence of joint and ligament injuries sustained to the fingers over the course of their sports activity. This necessitates specific strategies in the future to prevent injuries and long-term posttraumatic deficits.

Functional Deficits in the Wrist and Finger Joints of Goalkeepers After 20 Years of Playing Recreational Football.

A 30-year-old amateur goalkeeper sustained simultaneous dislocation of the proximal and distal interphalangeal joints of the ring finger and of the proximal interphalangeal joint of the middle finger following a hyperextension injury. This was reduced under a local anaesthetic. Neighbour finger strapping and early mobilisation achieved an excellent functional outcome when reviewed at eight weeks after the initial injury.
