1 Rachel Kloentrup ATTR 540 Research Methods in Human Performance

2 ◦ 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

3 ◦ To determine the effectiveness of SASTM in the treatment of lower body tendinopathy.

4  SASTM combined with an eccentric exercise program will be effective in the treatment of lower body tendinopathy.

5  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

6  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

7  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)

8 ◦ 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

9 ◦ 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

10 ◦ 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

11  VISA-A and VISA-P questionnaires  Value of 0 to 100 (VISA-A and VISA-P)VISA-AVISA-P  Friedman  Wilcoxon Signed Ranks test

12 Treatment Four – Base Line Treatment Six – Base Line Treatment Four – Treatment Three Treatment Five – Treatment Three Treatment Six – Treatment Three Z Asymp. Sig. (2- tailed)

13  Results ◦ Accept hypothesis:  SASTM combined with an eccentric exercise program will be effective in the treatment of lower body tendinopathy.
