22,27 The preservation of BMD in lumber spine is more than that in long bones.20 It may be due to the maintain of the loads on the spine while sitting in a wheelchair. There is only one study, which specifically mentioned that walking with orthosis brought a lot of physiological benefits for the subjects without presenting any evidence.8    Unfortunately many Inhibitors,research,lifescience,medical textbooks in this field refer to that paper without considering the results of other research studies.57-59 The other important parameters regarding the influence of standing and walking on BMD is the duration of using an orthosis. It was shown that walking and standing with an orthosis must be life-long, and must

be repeated several times a week to have any effects on bone osteoporosis (at least five session a week and one hour every cession). The use of mechanical orthoses and the neurological status (muscles stress), to remain ambulatory are two important parameters which influence BMD. However the findings of various research

Inhibitors,research,lifescience,medical studies have shown that the effect of the latter is more important (table 1 and ​and22).28 Table 2 The findings of various studies regarding the effects of standing and walking on skin integrity It seems that the Inhibitors,research,lifescience,medical type of injury, wether or not complete, influences the BMD. The patients with incomplete lesion have more BMD than those with a complete one.24,25 Therefore, every effort should be made to prevent turning an incomplete SCI into a complete one (table 3). Last but not least important point regarding the effects of using orthosis on the BMD of SCI patients is that some of the research studies, which their outcome differs Inhibitors,research,lifescience,medical from SCI, have been carried out on patients with spina bifida and myelomeningocele patients.8,31 Table 3 The findings of various studies regarding the effects of standing and walking on check details improving bowel and bladder function and urinary tract infection The results of various studies regarding the effects of using orthosis on spasticity are shown Inhibitors,research,lifescience,medical in table 4. As the table shows, the majority of researches cited are survey-based.

The investigators had sent questionnaires to individuals with SCI. Unfortunately, most of the subjects did not return the questionnaires. According to the findings of different investigations undertaken on SCI subjects, there was a favourable response to the use of orthosis on spasticity.26,33 There are a number of ways, which can be used until to measure spasticity clinically and biomechanically such as using Ashworth scale, counting beats of clonus, Tardieu scale, muscle stretch reflexes, and functional tests.60 Table 4 The findings of various studies regarding the effects of standing and walking on improving joint range of motion and decreasing muscle spasticity It seems that standing and walking with an orthosis extends the hip and knee joints, and stretches the surrounding muscles. So, applying body weight through leg reduces muscle spasm more efficiency than stretching the muscles only in a supine position.
