Rachel Kloentrup ATTR 540 Research Methods in Human Performance
◦ Chronic injury Achilles and patellar tendonitis ◦ Conservative treatment methods Eccentric exercise program Most effective in treatment of achilles (Mafi, N., Lorentzon, R., Alfredson, H. Superior, 2001) and patellar tendinopathy (Jonsson, P., Alfredson, H., 2005) Deep tissue massage Sound Assisted Soft Tissue Mobilization (SASTM) ◦ Lack of conclusive research
◦ To determine the effectiveness of SASTM in the treatment of lower body tendinopathy.
SASTM combined with an eccentric exercise program will be effective in the treatment of lower body tendinopathy.
Procedures ◦ Approval from the Manchester University IRB Subject Selection ◦ 9 student athletes ◦ Manchester University ◦ Achilles or patellar tendinopathy ◦ Informed consent ◦ Demographics Age, gender, sport, tendinopathy ◦ Informational eccentric exercise session ◦ VISA questionnaire
Delimitations ◦ Achilles tendinopathy Excluded if they have a history of ankle injury within the past 6 months ◦ Patellar tendinopathy Excluded if they have a history of knee injuries within the past 6 months ◦ Out of season athletes Limitations ◦ Small sample size
Instrumentation ◦ Eccentric Exercise Program Education session Achilles tendinopathy Calf raises using a stair (Achilles eccentric exercises)Achilles eccentric exercises Patellar tendinopathy 25° decline board (Patellar eccentric exercises)Patellar eccentric exercises Decline causes the calf muscles to relax in order to increase the stress on the knee extensor muscles (quadriceps)
◦ Measurement Techniques Victorian Institute of Sport Assessment-Achilles tendinopathy (VISA-A) (Robinson, J.M., Cook, J.L., Purdam C., et. al., 2001) VISA-A VISA-A Victorian Institute of Sport Assessment-patellar tendinopathy (VISA-P) (Zwerver, J., Kramer, T., Akker-Scheek, I., 2009) VISA-P VISA-P
◦ Sound Assisted Soft Tissue Mobilization Assist the clinician’s hands Polymer coated tools transmit sound waves through the tissue Controlled microtrauma to soft tissue in order to promote the healing process Clinician must be specially trained
◦ Eccentric exercise program performed daily ◦ VISA questionnaire prior to treatment ◦ SASTM 2 treatments per week (2 days rest between) for 3 weeks 5 minute SASTM treatment time
VISA-A and VISA-P questionnaires Value of 0 to 100 (VISA-A and VISA-P)VISA-AVISA-P Friedman Wilcoxon Signed Ranks test
Treatment Four – Base Line Treatment Six – Base Line Treatment Four – Treatment Three Treatment Five – Treatment Three Treatment Six – Treatment Three Z-2.016-2.077-2.081-2.386-2.549 Asymp. Sig. (2- tailed) 0.0440.0380.0370.0170.011
Results ◦ Accept hypothesis: SASTM combined with an eccentric exercise program will be effective in the treatment of lower body tendinopathy.
