|Title:||The immediate effect of lumbar spine manipulation, thoracic spine manipulation, combination lumbar and thoracic spine manipulation and sham laser on bowling speed in action cricket fast bowlers||Authors:||Sood, Kanwal Deep||Keywords:||Chiropractic;Spinal adjustment;Cricket players;Cricket--Bowling||Issue Date:||2008||Abstract:||To compare trunk flexion and lateral flexion range of motion (ROM) pre-post intervention. To compare the bowling speed of Action Cricket fast bowlers pre-post intervention. To determine the correlation between change in bowling speed immediately post-intervention to change in trunk flexion and lateral flexion ROM immediately post-intervention. To determine the association between change in bowling speed immediately post-intervention and the subjects’ perception of change in bowling speed. Methods: Forty asymptomatic Action Cricket fast bowlers were divided into four groups of ten each. Group 1 received lumbar spine manipulation, Group 2 received thoracic spine manipulation, Group 3 received combined thoracic and lumbar spine manipulation and Group 4 received the sham laser intervention (placebo). Pre- and post-intervention trunk flexion and lateral flexion ROM and bowling speed were measured using a digital inclinometer and a SpeedTracTM Speed Sport Radar. The subjects’ perception of a change in bowling speed post-intervention was also recorded. SPSS version 15.0 was used to analyse the data. Two-tailed tests were used in all cases. Results: Trunk flexion and lateral flexion increased significantly (p < 0.05) post-spinal manipulation. There was a significant increase in bowling speed post-thoracic (p = 0.042) and post-combined manipulation (p < 0.000). A significant yet weak positive correlation (p = 0.003; r = 0.451) was seen in change in bowling speed and change in thoracic flexion and lateral flexion. There was no significant difference in the percentage subjective change by intervention group (p = 0.217). Conclusions: Spinal manipulation is a valid intervention for short-term increase in bowling speed.||Description:||Dissertation submitted in partial compliance with the requirements for the Master's Degree in Technology: Chiropractic, Durban University of Technology, 2008.||URI:||http://hdl.handle.net/10321/434|
