Department of Rehabilitation Services. this tool will Arm care programs need to be well thought out with consideration for strength and mobility, but also the level of complexity associated with the program. 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.

After the surgery, the hand and forearm are immobilised in a splint that is placed over the bandages with the wrist and fingers in a slightly bent position, in order to protect the repair.[14]. This allows it to flex the digits individually at their proximal interphalangeal joints. The function of flexor digitorum superficialis can be observed by flexing a single digit against moderate resistance. This results in improvements in DIP joint flexion and differential glide. You can increase the resistance on each Powerweb by increasing the number of grids within your grip.
