Association between core strength and dynamic balance of throwing hand in professional healthy cricket fast bowlers: A cross sectional study.

Background: The core musculature gets activated by feed forward fashion during the movement of upper extremity, as in kinetic chain of throwing, shoulder muscle contributes larger dynamic balance and also in reversed manner. Aim of the current study was to associate the strength of core and the dynamic balance of throwing hand in cricket fast bowlers.

Methods: 72 subjects were initially screened for eligibility, and ultimately, 55 male participants from various cricket coaching academies, aged 19.

Inter-rater reliability of the dynamic neuromuscular stabilization diaphragm tests among individuals with non-specific low back pain and neck pain.

Background: The Dynamic Neuromuscular Stabilization (DNS) diaphragm test and intra-abdominal pressure regulation test (IAPRT) are qualitative clinical tests that assess postural stability provided by the diaphragm.

Objective: Evaluate the inter-rater reliability of the diaphragm test and IAPRT between an experienced and novice DNS clinician among individuals with non-specific low back pain (LBP) and neck pain.

Methods: Forty-five participants with non-specific LBP and/or neck pain were assessed by an experienced and novice DNS physiotherapist in the diaphragm test and IAPRT, and scored on a visual analog scale (VAS) according to five different criteria.
