Posterior opposing muscles (infraspinatus and teres minor)
Limiting factors for GH lateral rotation
Anterior part of fibrous capsule and all three bands of the glenohumeral ligament.
Anterior opposing muscles (subscapularis)
Limiting factors for elbow flexion
Apposition of anterior muscles of the arm and forearm Fibrous capsule (posterior part) Opposing muscles (triceps etc)
Limiting factors for elbow extension
Fibrous capsule (anterior part) Opposing muscles (biceps, brachialis etc) Radial and ulnar collateral ligaments (anterior parts)
Limiting factors for supination
Quadrate ligament (some fibres)
Passive resistance in pronator teres
Limiting factors for pronation
Passive resistance of the opposing muscles (supinator)
Quadrate ligament (some fibres)
Limiting factors for wrist flexion
Dorsal radiocarpal ligament Tension in the extensor tendons
Limiting factors for wrist extension
Palmar radiocarpal ligament Palmar ulnocarpal ligament Tension in the flexor tendons
Limiting factors for radial deviation
Ulnar collateral carpal ligament
Impact of scaphoid tubercle on the radial styloid
Limiting factors for ulnar deviation

Limiting factors for thumb flexion
Joint surface alignment Tension in surrounding soft tissues particularly the Post. Oblique lig.
Limiting factors for thumb extension
Joint surface alignment Tension in surrounding soft tissues particularly the Ant. Oblique lig.
Limiting factors for thumb abduction
Tension in thumb web
Limiting factors for thumb adduction
Apposition of the medial surface of the thumb with the hand
Limiting factors for thumb opposition
Joint surface alignment
Tension in surrounding soft tissues & contact of thumb pad with the palmar surface of the hand
Limiting factors for MCP flexion
Tension in the
extensor tendons Collateral ligaments are taut
Limiting factors for MCP extension
Tension in the flexor tendons
Extent of articular surface
Limiting factors for MCP abduction
Tension in finger and thumb webs
Limiting factors for MCP adduction

Limiting factors for Cervical Flexion
Anterior part of the disc is compressed whilst the posterior part is stretched
Tension also occurs in:
- Posterior longitudinal ligament
- Posterior capsule of the facet joints
- Ligamentum flavum,
- Interspinous ligament
- Ligamentum nuchae
- Opposing muscles.
Limiting factors for Cervical extension
Posterior part of disc compressed whilst anterior part stretched
Tension also occurs in:
- Anterior longitudinal ligament
- Approximation of spinous processes
- Tension in opposing muscles.
Limiting factors for Cervical rotation
Torsional deformity of the disc occurs
Plus tension develops in the ligaments of both sides and both facet joint capsules
Plus tension in the Alar ligaments of the Atlanto-axial joints.
Limiting factors for Cervical lateral flexion
(L) Lateral Flexion:
(L) side of the disc is compressed whilst the (R) side of disc is stretched
Tension in the facet joint capsule on the (R) side
Tension in the ligaments on the (R) side
Tension in the opposing muscles on the (R) side.
