1. The document discusses hip and lower limb function, focusing on common dysfunctions seen clinically such as gluteus medius inhibition and overactivity of the tensor fascia latae and iliotibial band. 2. Weak hip abductor and external rotator muscles like the gluteus medius are linked to problems like lower back pain and injuries. Exercises are demonstrated to target these muscles. 3. A single leg squat assessment shows correlations between weaknesses in the external hip rotators and increased injury risk, demonstrating the importance of addressing strength imbalances.

3. Movement is a behaviour Developmental and learned Quality over quantity Posture is a good baseline for movement Posture is not the cause of dysfunction but a SYMPTOM Such dysfunction corresponds to compromised activity of muscles Stabilisers typically become hypotonic/inhibited – ‘allowing’ faulty posture Gross movers typically become hypertonic/facilitated – ‘driving’ faulty posture Prescription Paradigms

4. Joint by joint approach Foot Stable unstable Ankle Mobile Stiff Knee Stable unstable Hip Mobile Stiff Western Foot!! Lx Spine Stable unstable Tx Spine Mobile Stiff Scapula Stable unstable GH Joint Mobile Stiff Prescription Paradigms

5. Gluteus Maximus Primary hip extensor and external rotator* Important for maintaining upright posture Stabiliser of SIJ via attachment to TLF Supports hip and knee via ITB attachment Functional role in stepping, running, climbing etc. and… DECELERATION

6. Gluteus Medius Primary abductor and controller of rotation of the hip* Functionally supports pelvis during SL stance and gait Plays rotator cuff-like role Strongest in neutral or slight adduction

7. Tensor Fascia Latae Primary functions are hip flexion, internal rotation and abduction (via ITB) Works in synergy with glute max: Tighten ITB to extend knee joint Control movements of pelvis on femur and femur on tibia when weight bearing

8. Iliotibial Band Thick, lateral aspect of fascia lata Attachment point for glute max, TFL Indirect insertion onto patella Anatomically impossible to stretch effectively

9. Piriformis & External Hip Rotators Primarily lateral rotator of the hip In hip flexion, will also abduct the hip Secondary phasic stabiliser of the SIJ Close relationship to sciatic nerve Piriformis syndrome

10. VastusMedialis & Lateralis Primary action is knee extension in inner range- 15-20deg of knee flexion Provide medial and lateral stability to patella respectively Perform anticipatory role Often dysfunctional (knee pain, pronation)

11. Hip Knee Foot Dysfunction Site of chronic injury often not the cause. Dysfunction at proximal sites often predispose more distal sites to excessive trauma. Injured site must received best practice care. Origin of dysfunction must be addressed.

12. Single Legged Squat Functional strength exercise Assessment tool

16. Predominance for TFL/ITB abduction stabilisation

18. Greater knee internal rotation

20. more dominant GlMax and TFL use the ITB sling to stabilise the pelvis

21. However, typically evidenced dysfunction of Gl Max. This results in the TFL being the primary active muscle

22. the body looks for an external rotator of the hip to act as a force-couple for the TFL

24. Overuse injuries often due to misalignment

25. Structure and location allocate blame to hip and ankle/foot.
