Collagen fiber alignment. A: By 16 weeks, collagen alignment was increased at the site of injury (insertion), as depicted by a decreased circular standard deviation, for tendons treated with HF PEMF (3 hr). B: HF PEMF (3 hr) also demonstrated improved collagen alignment in the tendon midsubstance at 8 weeks. HF PEMF (1 hr) and Physio-Stim (6 hr) also improved collagen alignment in this region at 16 weeks. No adverse effects were seen. Data represented as mean+SD. * denotes p<0.05. # denotes p<0.0083 which corrects for multiple comparisons.
