Sciatic Nerve Causing Plantar Fascitis?

In the Journal of Orthopaedic Research – September 2006, Coppieters MW, Alshami AM, Babri AS, et al measured the strain and excursion of the sciatic, tibial and plantar nerves with a modified straight leg raise (SLR) test. By bending the ankle into dorsiflexion first before raising the leg, nerve movement at the ankle, particularly the tibial nerve was greatly increased. Clinically, the diagnosis of ‘plantar fascitis’ can be caused by multiple sources, one being sensitization of the tibial nerve which is a branch of the sciatic nerve. Thanks to Dr. Coppieters, as well as other neurodynamic specialists like Michael Shacklock MAppSc, DipPhysio, we now know that movement of nerves occurs greatest where joints move first, a concept called ‘neurodynamic sequencing’….

Hamstring Injuries

In, Hoskins W, Pollard H. Hamstring injury management – Part 1: Issues in diagnosis. Manual Therapy 2005;10:96-107, the authors provide a research review of the possible factors in hamstring injury. Muscle strength and balance: Various studies have found different ratios in quadriceps and hamstring strength ratios, which could be dependent on the specific sport. Warm up: There is a lack of literature existing to identify best warm-up procedures Fatigue: The authors showed that fatigue is a factor as the incidence of hamstring injuries occurred greatest at the end of a games or matches (Woods 2004). Flexibility: There is conflicting evidence on the relationship of hamstring flexibility and injury. Body Mechanics: The authors found that poor lumbo-pelvic mechanics can indirectly cause…
