Learning Objectives
Upon completion of this chapter, you will be able to:
- Understand basic functional anatomy for the lumbo-pelvic-hip complex.
- Understand the mechanisms for common lumbo-pelvic-hip complex injuries.
- Determine common risk factors that can lead to lumbo-pelvic-hip complex injuries
- Incorporate a systematic assessment and corrective exercise strategy for lumbo-pelvic-hip complex impairments.
Introduction
The lumbo-pelvic-hip complex (LPHC) is a region of the body that has a massive influence on the structures above and below it. Th e LPHC has between 29 and
35 muscles that attach to the lumbar spine or pelvis ( 1, 2 ). The LPHC is directly associated with both the lower extremities and upper extremities of the body. Because of this, the dysfunction of both the lower extremities and upper extremities can lead to dysfunction of the LPHC and vice versa.
Review of LPHC Functional Anatom
Iliofemoral joint
Sacroiliac joint
The femur and pelvis
pelvis and sacrum
Thoracolumbar and Cervicothoracic junctions of the spine
the tibia, fibula, and talus
Collectively, these structures anchor the myofascial tissues of the LPHC such as the biceps femoris, medial hamstring complex, and rectus femoris. These bones and joints are of importance in corrective exercise because
they will also have a functional impact on the arthrokinematics of the LPHC
Muscles
There are a number of muscles in the upper and lower extremities whose function may be related and have an effect on the LPHC Table 14. 1. As with all muscles, it is important to restore and maintain a normal range of motion and strength, as well as eliminate any muscle inhibition to ensure joints are operating optimally ( 3 – 5 ). See chapter two for a detailed review of the location and function of these muscles.
Key Muscles Associated with the LPHC
Gastrocnemius/soleus
Adductor complex
Hamstring complex
Hip flexors
Abdominal complex
Erector spinae
Latissimus dorsi
Tensor fascia latae/IT-band
Gluteus medius and maximus
Common LPHC Injuries and Associated
Movement Deficiencies
Local Injuries:
Low-back pain
Sacroiliac joint dysfunction
Hamstring complex, quadriceps, and groin strains
Injuries Above LPHC:
Shoulder and upper-extremity injuries
Cervical-thoracic spine
Rib cage
Injuries Below the LPHC:
Patellar tendonitis (jumper’s knee)
IT-band tendonitis (runner’s knee)
Medial, lateral, and anterior knee pain
Chondromalacia patellae
Plantar fasciitis
Achilles’ tendonitis
Posterior tibialis tendonitis (shin splints)

The gluteus maximus and latissimus dorsi along with the thoracolumbar fascia.
As a compensatory mechanism for the underactivity and inability of the gluteus maximus to maintain an upright trunk position, the latissimus dorsi may become synergistically dominant (overactive or tight) to provide stability through the trunk, core, and pelvis
the deep longitudinal subsystem
The erector spinae, sacrotuberous ligament, biceps femoris, peroneus longus,
and anterior tibialis work synergistically to form
SYSTEMATIC PROCESS TO DETERMINE LPHC IMPAIRMENTS
Because of the freedom of movement at the LPHC and its association with the
upper and lower extremities, there are a number of key elements to assess
for LPHC dysfunction.
SYSTEMATIC PROCESS TO DETERMINE LPHC IMPAIRMENTS
cont
A key static postural distortion syndrome to look for to determine potential
movement dysfunction at the LPHC is the lower crossed postural distortion
syndrome
This position of the pelvis and lumbar spine can
place excessive stress on the muscles and connective tissue associated with the LPHC during dynamic movement.
SYSTEMATIC PROCESS TO DETERMINE LPHC IMPAIRMENTS
TRANSITIONAL MOVEMENT ASSESSMENTS
There are several LPHC compensations to look for when performing an overhead squat assessment. As outlined in chapter six, these compensations include excessive forward lean, arching of the low back, rounding of the low back, and an asymmetric weight shift.
SYSTEMATIC PROCESS TO DETERMINE LPHC IMPAIRMENTS
DYNAMIC MOVEMENT ASSESSMENTS
Dynamic movement assessments can also help to determine whether LPHC
movement deficiencies exist while performing more dynamic movements such as gait (chapter six). When performing a gait assessment, observe the individual’s LPHC for excessive arching and excessive pelvic rotation as well as hip hiking. These compensations could be indicative of poor neuromuscular control of the LPHC and will need to be addressed in the corrective exercise program.
SYSTEMATIC PROCESS TO DETERMINE LPHC IMPAIRMENTS
RANGE OF MOTION ASSESSMENTS
The range of motion (ROM) assessments performed for LPHC impairments will be dependent on the compensations seen during the overhead squat assessment. The table provides a summary of key joints to be measured on potential observations on the basis of the movement compensation(s) seen in the movement assessment.
SYSTEMATIC PROCESS TO DETERMINE LPHC IMPAIRMENTS
STRENGTH ASSESSMENTS
As with the ROM assessments, the manual muscle tests that are selected will also be dependent on the compensations seen during the overhead squat assessment. The table provides a summary of key muscles to be tested on the basis of the movement compensation(s) seen in the movement assessment. See chapter eight to view the proper execution of these assessments.
