External oblique; Because of this, she recommended practicing vertical pull exercises to get used to the motion and gravity involved. Median nerve (C7, C8, T1) [1] Artery. Another mechanism of injury is a rupture rather than a laceration, for example the FDP tendon has ruptured from its insertion at the distal phalanx - usually this is caused by a closed mechanism of injury. Flexor Function. Variation of the absence of one tendon for the little finger of flexor digitorum superficialis. This expanded program incorporated throwing motion-specific exercises and movement patterns performed in a discrete series, utilizing principles of coactivation, high-level neuromuscular control, dynamic stabilization, muscular facilitation, strength, endurance, and coordination, which all serve to restore muscle balance and symmetry in the overhead throwing athlete.7 The evolution of these arm care programs has been an asset to the baseball community, offering the opportunity for pre-season and off-season strengthening for injury prevention and sports performance. Hand Therapy. But since most people do this exercise slumped in a chair rather than while walking (as with the static holds), it doesnt have as much functional carryover to everyday activities.

During the pitching motion, the infraspinatus peaks muscle activation during the late cocking phase (74%), while the teres minor muscle activity peaks during the deceleration stage (84%).2 This exercise has been shown to activate the infraspinatus between 50-88% MVC, while teres minor activation will reach a lower level of 39% MVC.5,12,18,19 The NISMAT Arm Care program encourages this exercise to start with a scapular retraction during the row. During the pitching motion the infraspinatus reaches its peak MVC during late cocking (74%), supraspinatus reaches its peak MVC during early cocking (60%), teres minor reaches its peak MVC during deceleration (84%) and posterior deltoid reaches peak during acceleration (68%).2,8,19 Historically, the side-lying external rotation exercise has been shown to activate these muscles: infraspinatus 42-62% MVC, supraspinatus 51% MVC, teres minor 67% MVC and posterior deltoid 52% MVC.12,18 The NISMAT Arm Care program, based on Krause et al.21 recommends using a side plank position to elevate the muscle activity in posterior deltoid and infraspinatus. our 'Cookies The pronator teres reaches 88% MVC and flexor digitorum superficialis reaches 80% MVC during the acceleration stage of pitching.2 Fukunaga et al.25 showed the pronation using elastic resistance activated pronator teres 73% MVC and the flexor digitorum superficialis 64% MVC.

For a flexor injury, the patient needs to keep the fingers cupped with the wrist in neutral if the splint is off. the type of splint design that patient will need, Zone I - distal to the flexor digitorum superficialis (FDS), Zone II - from the FDS insertion to distal portion of the A1 pulley, Zone III - from the A1 pulley to the transverse carpal ligament, Zone I - distal to the interphalangeal joint (IP) in the thumb, Zone II - between the metacarpophalangeal (MCP) and interphalangeal (IP) joints, Zone III - proximal to the metacarpophalangeal (MCP) volar/palmar flexion crease, Loss of active flexion strength or motion of the involved digit(s), Pain when attempting to flex the involved digit, Flexor Digitorum Profundus (FDP) tendon - the patient is unable to flex the distal interphalangeal joint (DIP) in isolation, Flexor Digitorum Superficialis (FDS) tendon - isolate the involved/affected finger and ask the patient to flex the proximal interphalangeal joint (PIP), Flexor Pollicis Longus tendon - flexing the interphalangeal joint (IP) joint of the thumb in isolation, lasts from day one to day seven post-operatively, in this stage, fibroblasts produce type III collagen and macrophages help initiate healing and remodelling, this runs from day 8 to about three weeks post-operatively, tissue modelling via large amounts of disorganised collagen happens during this stage, angiogenesis also happens during this stage, occurs up until about 18 months post-operatively, in this stage, tensile forces lead to tissue remodelling, and type III collagen is replaced with type I collagen, this happens in a more linear fashion, and this creates cross-linking to build strength in the tendon. Flexor Tendon In 1983, Dr. Frank Jobe pioneered the original EMG study on the deltoids, subscapularis and what they referred to as the SIT muscles (supraspinatus, infraspinatus, and teres minor) during the pitching motion.1 This work continued to advance through the 1980s and early 1990s with Jobe et al.1 and DiGiovine et al.2 giving clinicians a better understanding of the muscle activity and performance demands of the entire upper extremity during the pitching motion.
