Stretching for Impaired Mobility Chapter 4
Stretching: Definition and Purpose • A general term used to describe any therapeutic maneuver designed to increase mobility of soft tissues and subsequently improve ROM by elongating (lengthening) structures that have adaptively shortened and have become hypomobile over time
Definitions of Terms Related to Mobility and Stretching • Flexibility • Dynamic flexibility • Passive flexibility • Hypomobility • Hypomobility may be allowed selectively to improve function
Definitions of Terms Related to Mobility and Stretching (cont'd) • Contracture • Designation of contracture by location • Contracture versus contraction • Types of contracture • Myostatic contracture • Pseudomyostatic contracture • Arthrogenic and periarticular contractures • Fibrotic contracture and irreversible contractures
Definitions of Terms Related to Mobility and Stretching (cont'd) • Selective Stretching • Hypomobile structures to develop to improve function • Overstretching and Hypermobility • Hypermobility improves function in some circumstances
Interventions to Increase Mobility of Soft Tissues • Manual or Mechanical Stretching • Utilizes an external force • Passive Stretching • No patient assistance • Assisted Stretching • Patient assistance • Self-Stretching • Patient performs the stretch
Interventions to Increase Mobility of Soft Tissues (cont'd) • Neuromuscular Facilitation and Inhibition Techniques • Muscle Energy Techniques • Joint Mobilization/Manipulation • Soft Tissue Mobilization and Manipulation • Neural Tissue Mobilization (Neuromeningeal Mobilization)
Indications for Stretching Exercises • Adhesions, Contractures, Scar Tissue Limit ROM • Potential for Structural Deformity d/t Limited ROM • Muscle Weakness, Shortening of Muscles • Part of a Total Fitness Program • Pre and Post Vigorous Exercise
Contraindications for Stretching Exercises • Bony Block • Non-Union Fracture • Acute Inflammation or Infection • Sharp or Acute Pain With Elongation • Hematoma or Tissue Trauma • Hypermobility • Hypomobility Provides Stability or Neuro-muscular Control
