Abstract

Introduction: Children with diagnosis of leukemia are at risk for developingneuromuscular and musculoskeletal complications such as decreasedmuscle strength, impaired gross and fine motor performance, decreasedenergy expenditure, osteonecrosis, and osteoporosis. These secondarycomplications due to the medical interventions may lead to activitylimitations and participation restrictions in daily life experiences.However, few Authors suggest that if children participate in an individualizedphysical therapy exercise program, these limitations may be preventedor at least reduced. We evaluated the level of physical fitness onchildren with diagnosis of leukemia (C-LK) during the post-chemotherapyperiod.Subjects and methods: Nine (8,3±2,7 yrs) C-LK of both sex participatedto the study with the consents of their parents. We also recruited agroup of thirty-two healthy children of both sex with similar age(8,12±1,56 yrs) as control group (GC). In order to assess the fitness levelof the experimental sample we used few fitness tests already validatedby scientific papers. Standing broad jump, 4 x 10 m shuttle run test,sit up test and handgrip strength test were administered three times in aperiod of two weeks during the period of May 2012. Exclusion criteriafor C-LK were at least six months of therapy stopped and for CG no regularlyphysical activity participation. The scores coming from the bestperformances were used for statistical purpose.Results: Preliminary results shown no differences in standing broadjump performances. C-LK reported a mean value of 112,55±32,80 cm,while CG reported 124,18±22,19 cm, p = 0.11. An interesting findingsis coming from 4 x 10 m shuttle run test. The C-LK group performed thetest in a mean value of 16.27±0.83 seconds, while the control performedthe same test in 14.02±0.25 seconds, p = 0.001. No differences betweengroups were found when comparing sit-up performances (0.25) andhandgrip performances (0.08 left arm and 0.15 right arm), respectively.Conclusions: The level of physical fitness of C-LK group seems to bein line with control group results. These preliminary data are confirmingthe eligibility of C-LK to start with specific exercise programs in orderto reduce cardiovascular and muscular complications and improvequality of life. The only concern is about the agility test (4 x 10 SRT)who shown a very high significant differences, 2 seconds in 40 mtsprint. To date, the sample size is not adequate to make conclusions.More data coming from C-LK groups are necessary to better understandthis topic.
