Jonsie, box rest is not the best for temdons. Limited freedom of movement greatly encourages adhesions forming in the tendon and increases scaring. Movement allows the tendon to still stretch naturally and improves blood flow greatly to the injury site.
Stick the horse in a large yard 24/7. The horse will still be rather sensible as it will stiil hurt if he is too energetic.
Also excessive strapping just traps the heat in and cooks the tendon, hindering the healing process and inflammation reduction. Icing and hosing is so very imperitive in the first few weeks.
