7 children 15 to 30 mo. old participated in a study of 3–dimensional kinematics of overarm throwing. Children of different ages were considered to be at different developmental stages of motor development. Video recordings were digitised and 3-dimensional coordinates established using the DLT algorithm. Qualitative analysis indicated that the children executed either a ‘static’ or ‘dynamic’ throwing action. Either could further be classified as ‘arm dominated’ or ‘sequentially linked.’ Maximum elbow extension was no more than 163° for any child; release velocity was higher for older subjects; and the angle of ball release was large in ‘arm-dominated throws’ ( M = 49°) and comparatively smaller in ‘sequentially linked’ throws ( M = 15°).

Brachial Plexus Surgery

Abstract BACKGROUND AND IMPORTANCE: Restoration of elbow extension has not been considered of much importance regarding functional outcomes in brachial plexus surgery; however, the flexion of the elbow joint is only fully effective if the motion can be stabilized, what can be achieved solely if the triceps brachii is coactivated. To present a novel nerve transfer of a healthy motor fascicle from the ulnar nerve to the nerve of the long head of the triceps to restore the elbow extension function in brachial plexus injuries involving the upper and middle trunks. CLINICAL PRESENTATION: Case 1 is a 32-year-old man sustaining a right brachial extended upper plexus injury in a motorcycle accident 5 months before admission. The computed tomography myelogram demonstrated avulsion of the C5 and C6 roots. Case 2 is a 24-year-old man who sustained a C5-C7 injury to the left brachial plexus in a traffic accident 4 months before admission. Computed tomography myelogram demonstrated signs of C6 and C7 root avulsion. The technique included an incision at the medial border of the biceps, in the proximal third of the involved arm, followed by identification of the ulnar nerve, the radial nerve, and the branch to the long head of the triceps. The proximal stump of a motor fascicle from the ulnar nerve was sutured directly to the distal stump of the nerve of the long head of the triceps. Techniques to restore elbow flexion and shoulder abduction were applied in both cases. Triceps strength Medical Research Council M4 grade was obtained in both cases. CONCLUSION: The attempted nerve transfer was effective for restoration of elbow extension in primary brachial plexus surgery; however, it should be selected only for cases in which other reliable donor nerves were used to restore elbow flexion.

The purpose of this study was to assess the effects of consuming electrokinetically modified water (EMW) on attenuating muscle damage and improving functional recovery following a single bout of isokinetic resistance exercise. Subjects were randomly assigned to an EMW ( n = 20) or a placebo control ( n = 20) group. Subjects consumed EMW or placebo water daily for 23 days. On day 19 subjects completed an exercise protocol for the biceps brachii to induce muscle damage. The protocol consisted of three sets of 20 repetitions using concentric and eccentric contractions of the elbow flexors. Blood draw and clinical measurements were performed preexercise as well as 24, 48, and 96 h postexercise. Clinical measures included maximal isometric strength, muscle soreness, pain with elbow extension, relaxed elbow angle (RANG), and self-report arm disability. Plasma samples were analyzed to determine concentrations of creatine kinase (CK) and high-sensitivity C-reactive protein (hsCRP). Pain with elbow extension and self-report arm disability were significantly higher in the placebo group compared with the EMW group at 48 h ( P < 0.01) and 96 h ( P < 0.01) after exercise, while RANG was significantly higher in the EMW group compared with placebo at 48 h ( P < 0.01) and 96 h ( P < 0.01) after exercise. Similarly, plasma concentrations for hsCRP and CK were significantly lower in the EMW group compared with placebo at 48 h ( P < 0.05) and 96 h ( P < 0.01) after exercise. Oral consumption of EMW significantly reduced exercise-induced muscle damage and inflammation and improved functional recovery.

This study compared the kinematic parameters of swing mechanics under toss batting (TB), motor imagery (MI), video projection (VP), and virtual reality (VR) conditions during baseball batting. Nine college baseball players performed three swings to hit a tossed ball under TB conditions or a virtual ball under MI, VP, and VR conditions. The results revealed that upper trunk backward rotation was smaller in the loading phase under the VP and VR conditions than under the TB and MI conditions and lower under VR than under the VP condition ( p < 0.05) except at the load event. Pelvic backward rotation was smaller under the VR condition than under the TB, MI, and VP conditions ( p < 0.05). In the swing phase, TB demonstrated higher peak velocity at the head of the bat, lead elbow extension, and pelvis and upper trunk rotation than did MI, VP, and VR, whereas VP also demonstrated higher peak velocity in pelvic forward rotation than did VR ( p < 0.05). In summary, VR demonstrates a more realistic response in the loading phase and reduced pelvic backward rotation but lower movement velocities. Coaches should pay attention to movement differences between swing conditions when arranging a swing training plan.
