To promote social and motor skills development among autistic children, an intervention consisting of Taekwondo and elements of music therapy was designed and implemented in Hong Kong. The objective of the current study is to investigate the effectiveness of this training, based on parents' observations of their children who had completed the key stage of the training.

Secondary Anterior Cruciate Ligament Injury Prevention Training in Athletes: What Is the Missing Link?

After reconstruction, the return to full competition rate of athletes is low, while the re-injury rate remains high despite the completion of a rehabilitation programme. Primary ACL prevention programmes are well developed, yet few research papers focus on secondary ACL injury prevention. The aim of current review is to determine if current ACL secondary prevention training has a positive influence on the re-injury rate, the clinical or functional outcomes, or the risk of re-injury in athletes.

Knee wobbling during the single-leg-squat-and-hold test reflects dynamic knee instability in patients with anterior cruciate ligament injury.

We propose using the single-leg squat-and-hold (SLSH) task with kinematic analysis to objectively measure dynamic knee stability after anterior cruciate ligament (ACL) injury. There are three objectives of this study: to compare the knee kinematics of ACL-deficient patients and healthy controls by capturing knee wobbling during the SLSH task, to detect kinematic changes after ACL reconstruction, and to correlate the kinematic variables with self-reported knee function. Twenty-five ACL-deficient participants and 18 healthy matched participants were recruited.

What have we learnt from quantitative case reports of acute lateral ankle sprains injuries and episodes of 'giving-way' of the ankle joint, and what shall we further investigate?

Lateral ankle sprains are a commonly incurred injury in sports. They have a high recurrence rate and can lead to the development of persistent injury associated symptoms. We performed a quantitative synthesis of published case reports documenting the kinematics of acute lateral ankle sprains and episodes of 'giving-way' of the ankle joint to provide a comprehensive description of the mechanisms.

An inverted ankle joint orientation at foot strike could incite ankle inversion sprain: Comparison between injury and non-injured cutting motions of a tennis player.

Delayed ankle muscle reaction time in female amateur footballers after the first 15 min of a simulated prolonged football protocol.

Purpose: Ankle sprain injury rate is reported to be higher towards the end of a football match. Muscle fatigue may contribute to the delayed muscle reaction and subsequent injury. This study investigated the ankle muscle reaction time during a simulated, prolonged football protocol.

Psychological processes of ACL-patients' post-surgery rehabilitation: A prospective test of an integrated theoretical model.

Objectives: The aim of this prospective study was to examine the utility of an integrated model comprising constructs from self-determination theory (SDT) and the theory of planned behavior (TPB) in predicting adherence to a post-surgery rehabilitation program in patients receiving anterior cruciate ligament (ACL) reconstruction. Constructs of the integrated model measured at baseline were expected to predict patients' rehabilitation adherence two months later.

Method: Patients (N = 121, M age = 27.

The biomechanical difference between running with traditional and 3D printed orthoses.

Running-related injuries have been associated with excessive foot pronation and high vertical loading rates. Traditional plaster-molded (TPM) foot orthoses are commonly prescribed to minimize these atypical biomechanical patterns. Recently, 3D printed (3DP) orthoses have become popular, yet the functional difference between these two types of orthoses remains unknown.

Kinematic analysis of a televised medial ankle sprain.

Ankle sprains are one of the most prevalent athletic injuries. Prior work has investigated lateral ankle sprains, but research on generally more severe medial sprains is lacking. This case report performs a kinematic analysis using novel motion analysis methods on a non-contact medial ankle sprain.

Social psychological aspects of ACL injury prevention and rehabilitation: An integrated model for behavioral adherence.

Managing rehabilitation for ACL injury is dependent on uptake of, and compliance with, medical and safety recommendations. In this paper, we propose a multi-theory model that integrates self-determination theory and the theory of planned behavior to identify the motivational determinants ACL injury prevention and management behaviors and the processes involved.
