All

Inclusion criteria

Inclusion criteria: The following criteria must be met in order to partake in this study: • Female or male patients between the ages of 18 to 44 years old to rule out the effects of degeneration on lumbar spine range of motion that results with increasing age. • Decreased hamstring flexibility as determined by a passive straight leg raise below 70°. • The following diagnostic criteria indicating sacroiliac joint dysfunction: o At least three positive provocative orthopaedic tests specific to the sacroiliac joint: FABER, gaenslen’s, sacroiliac compression. o Sacroiliac Marching Test (motion palpation) in order to determine which sacroiliac joint is dysfunctional.

Exclusion criteria

Exclusion criteria: If any of the following criteria are met, the participant cannot take part in this study: • Contraindicated for chiropractic manipulation of the sacroiliac joint. • Contraindicated for hamstring stretching. • Current or previous (up to eight weeks) hamstring strain as there will be pain and decreased range of motion on stretch. • Any hip pathology that would result in decreased hip flexion.

Design outcomes

Primary

MeasureTime frame
This study may determine if chiropractic manipulation of the sacroiliac joint, dynamic oscillatory stretching or a combination of the two, increase hamstring flexibility as well as which method is the most effective.

Secondary

MeasureTime frame
This study could determine whether sacroiliac joint dysfunction is directly linked with decreased hamstring flexibility and vice versa
