Physical Activity Levels and Adiposity in Ambulant Children and Adolescents With Cerebral Palsy Compared With Their Typically Developing Peers.

Purpose: This study assessed physical activity (PA) and body composition of ambulatory children and adolescents with cerebral palsy (CP) and their typically developing peers.

Methods: Participants included youth with CP (ages 8-18 y and Gross Motor Function Classification System [GMFCS] levels I-III) and their typically developing peers. Outcomes included PA (actigraphy) and fat/lean mass index (FMI/LMI; dual-energy X-ray absorptiometry).

Concussions and Injuries in Sledge Hockey: Grassroots to Elite Participation.

Objective: To examine injury (including concussion) rates, location, type, mechanisms, and risk factors in sledge hockey players.

Design: Cross-sectional survey.

Setting: Sledge hockey players, worldwide, across all levels of play.

Evaluating the Effect of Policy Prohibiting Body Checking on Physical Contacts in U15 and U18 Youth Ice Hockey Leagues.

Objective: To compare physical contacts (PCs) and head contacts (HCs) in nonelite U15 (ages 13-14) and U18 (ages 15-17) ice hockey players in body checking (BC) and non-BC leagues.

Design: Cohort video analysis study.

Setting: Ice hockey arenas in Calgary, Canada.

More Than Just Adolescence: Differences in Fatigue Between Youth With Cerebral Palsy and Typically Developing Peers.

Objective: To quantify differences in fatigue and disordered sleep between adolescents with cerebral palsy (CP) and their typically developing peers. A secondary aim was to investigate the association between fatigue and disordered sleep in adolescents with CP.

Methods: A convenience sample of 36 youth with CP aged 10-18 years was matched for age and sex with 36 typically developing peers.

Associations of inter-segmental coordination and treadmill walking economy in youth with cerebral palsy.

This study investigated associations of thigh-shank coordination deficit severity and metabolic demands of walking in youth with cerebral palsy (CP) and their typically developing (TD) peers. Youth (ages 8-18 years) with hemiplegic and diplegic CP [Gross Motor Classification System (GMFCS) I-III] and their age (within 12 months) and sex-matched peers performed a modified six-minute-walk-test on a treadmill. Kinematics (Motion Analysis, USA, 240 Hz) and mass-specific gross metabolic rate (GMR; COSMED, Italy) were analyzed for minute two of treadmill walking.
