FIRING PATTERNS B. J. Piccolo, LMT

FIRING PATTERN: PRONE HIP EXTENSION 1) 2) 3) 4) Gluteus Maximus Hamstrings Opposite Erectors Same-side erectors & hamstrings PROBLEMS: weak glut max, overactive synergist(hamstrings), overactive erector spinae(stabilizer), strong psoas SYMPTOMS: LBP, gluteal pain, recurring hamstring strain Janda proposed that the ideal order of muscle firing being: 1) Gluteus Maximus 2) Hamstrings 3) Contralateral erector spinae 4) Ipsilateral erector spine http: //videoduel. ru/watch? v=kl 4 i. DSy. IV m. J Irene’s Proposal: 1) Gluteus Maximus 2) Hamstrings 3) Ipsilateral erector spine 4) Contralateral erector spinae

FIRING PATTERN: SIDE LYING HIP ABDUCTION 1) Gluteus Medius 2) Tensor Fasciae Latae 3) QL PROBLEMS: weak glut med, overactive adductors, overactive synergist (TFL), overactive stabilizer(QL) SYMPTOMS: LBP, sacroiliac pain, gluteal pain, lateral knee pain, anterior knee pain

FIRING PATTERN: KNEE FLEXION 1) Hamstrings 2) Gastrocnemius SYMPTOMS: Pain behind knee, Achilles' tendonitis

FIRING PATTERN: KNEE EXTENSION 1) Vastus Medialis 2) Vastus Intermedius & Vastus Lateralis 3) Rectus Femoris SYMPTOMS: Knee pain under patella, patellar tendonitis

FIRING PATTERN: TRUNK FLEXION (SIT-UP) 1) Transverse Abdominus 2) Obliques 3) Rectus Abdominus PROBLEM: Weak abs, overactive antagonist erectors, overactive synergist(psoas/ rectus abdominus) SYMPTOMS: LBP, Gluteal pain, hamstring shortness

FIRING PATTERN: SHOULDER ABDUCTION 1) Supraspinatus 2) Deltoid 3) Infraspinatus 4) Mid/Low Trapezius 5) Contra lateral QL PROBLEM: weak agonist (Levator Scapula), overactive upper trap, overactive ipsilateral QL (stabilizer) SYMPTOMS: shoulder pain, headache at base of skull, upper chest breathing, LBP
