Patellofemoral chondropathy (PFC) is one of the most important causes of patellofemoral pain syndrome. PFC may occur as a result of anatomic reasons such as patellar malalignment and/or increased patellofemoral joint stresses. Most research on this subject has involved sports injuries and anatomic variations. The literature is scarce on PFC related to the dance. ⋯ Dance styles that include frequent deep flexions and strolling on a flexed knee joint may be risk factors for chondral lesions in the contact area of the femur in male dancers.

Case ReportsModified Graded Motor Imagery for Musicians' Focal Dystonia: A Case Series.
This study aimed to assess the effectiveness of the "modified graded motor imagery" (mGMI) protocol as a rehabilitative treatment of musician's focal dystonia (MFD). ⋯ The findings from this pilot study suggest that home-based mGMI treatment is a feasible and promising rehabilitative approach for patients with mild to moderate MFD.

Kinematic Analysis of the Coupling Between Calcaneal Eversion and Ankle Dorsiflexion in a Contemporary Dancer's Demi-Plié.
Dancing requires a high range of motion in the foot as well as a good shock-absorbing system formed by the foot and ankle joints. Although there is a broad consensus in dance that excessive calcaneal eversion can cause injury and should be avoided, calcaneal eversion is discussed controversially in the dance literature. An increased research focus on the biomechanics of dance, particularly research pertaining to the foot and ankle joints, might help to resolve this controversy. ⋯ Average calcaneal eversion is a poor indicator of the role calcaneal eversion plays in the demi-plié of contemporary dancers. Rather, the temporal coupling between calcaneal eversion and ankle dorsiflexion needs to be considered.

Implementation of Calf Endurance Training in a Touring Group of Professional Circus Performers: A Feasibility Study.
Demanding performance schedules in modern professional circus can result in less time for injury rehabilitation and strength and conditioning for injury prevention. Lower limb injuries are a common injury presentation in Cirque du Soleil touring show performers. ⋯ A single-leg calf raise exercise program can be feasibly introduced into a touring, performing professional circus show without increasing injury numbers or self-reported soreness. Furthermore, gains in calf raise endurance can be obtained during a 9-week intervention period.

Lower Limb Takeoff Mechanics During a Leap in Dancers With and Without Flexor Hallucis Longus Tendinopathy.
Altered ground reaction force (GRF) and joint torsional stiffness are associated with various lower extremity injuries, but these have yet to be examined in dancers with flexor hallucis longus (FHL) tendinopathy. Additionally, a simple, field-friendly kinematic correlate to ground contact kinetics would be useful for clinical application. The purpose of this study was to compare lower extremity biomechanics during takeoff of a dance leap (saut de chat) in dancers with and without FHL tendinopathy, and to examine lower limb posture at initial contact as a clinical correlate of injury-related kinetic factors. ⋯ Dancers with FHL tendinopathy demonstrated altered lower extremity kinetics during takeoff of a leap compared to uninjured dancers, which may contribute to, or be a compensation response to, injury.
