The Management of Valgus Extension Overload Syndrome Experienced with Hitting in a High School Baseball Player: A Case Report.

Background: Valgus extension overload syndrome (VEOS) of the elbow is a condition associated with overhead athletes. However, the non-surgical management of these individuals is not well documented.

Purpose: To discuss the unique presentation, management, and outcomes of an adolescent baseball player with a chronic history of VEOS experienced during hitting.

The influence of hip flexion mobility and lumbar spine extensor strength on lumbar spine flexion during a squat lift.

Study Design: Cross-sectional; Controlled laboratory study.

Objective: To examine the associations among available hip flexion motion, lumbar extensor strength and peak lumbar flexion during a squat lift task.

Summary Of Background Data: Lumbar spine flexion during lifting can result in increased strain on spinal structures.

The influence of hip extensor and lumbar spine extensor strength on lumbar spine loading during a squat lift.

Weakness of the hip extensors and lumbar spine extensors has been proposed to contribute to greater demands on the lumbar spine during lifting. The purpose of the current study was to examine the associations among strength of the hip and lumbar spine extensors, lumbar spine extensor moments and lumbar paraspinal muscle activation during a squat lift task. Twenty-seven healthy females participated.
