Introduction/Clinical Scenario Dizziness and imbalance are two of the most commonly-reported symptoms in the early stages of concussion. Anywhere from 23–81% of patients report dizziness in the days following injury. 1 – 3 An initial presentation of dizziness can be a predictor of prolonged

Anecdotal evidence suggests a relationship between strength imbalances and injury incidence.
To examine the relationship between bilateral strength imbalance and incidence of injury.
Participants and Design:
Thirty national- or international-standard flatwater kayakers were classified as noninjured, trunk injured, or upper-limb injured based on the number of days lost from training over the last 6 months. Bilateral strength imbalance was measured using a kayak ergometer, producing data for peak force and force impulse for each side of each stroke. Bilateral strength imbalance was then compared between the noninjured, trunk-injured, and upper-limb-injured groups by means of 2 one-way ANOVAs. No participants reported training days lost through lower-limb injury.
A significantly elevated bilateral peak-force strength imbalance was observed between the upper-limb-injured and the noninjured groups.
These data support the existence of a relationship between strength imbalance and incidence of injury.

high volume of training is more likely to produce a spinal deformity. 5 Those aforementioned movement patterns and training loads can generate postural alterations that give rise to painful actions, muscular imbalances, and the development of compensatory movement patterns, 7 which directly damage
