Sickle cell disease (SCD) is the most frequent life-threatening genetic hemoglobinopathy in the world and occurs due to the synthesis of abnormal hemoglobin S (HbS).Cells with sickle cell hemoglobin are stiff and sticky. When they lose their oxygen, they form into the shape of a sickle or crescent. This can cause pain and tissue damage. Significant decrease in exercise capacity was seen in sickle cell anemic children. In the absence of a guidelines that can guide the prescription of exercise in SCD children. This study is a step for determine the forms of prescription of pain on the balance and muscle strength to build up in future studies a safety of physical exercises for children with sickle cell anemia and improve their functional abilities.
Sickle cell anemia is a serious life-limiting and potentially life-threatening condition that causes disruption in the lifestyle of the affected child. Pain is a common and severe symptom of sickle cell disease (SCD) and is the major reason that patients seek health care services. Some researchers supported the fact that an important impairment in balance control and muscle strength in children with sickle cell disease due to pressure pain tolerance problems and other factors. Significant decrease in exercise capacity was seen in sickle cell anemic children. The altered muscle function and balance observed in SCD children may collectively be the result of pressure pain tolerance impairment. As your physical fitness improves, your body becomes more efficient at getting oxygen into the bloodstream and transporting it to the working muscles. Along this observational correlational study design; Eighty children from both sexes will be participated in this study. Forty normal healthy children will be selected from primary governmental schools at Alexandria governorate and forty children with sickle cell anemia will be selected from Alexandria University Students Hospitals For evaluation of muscle strength hand held dynamometer (Lafayette) is one of the best methods to detect the muscle strength. It is an ergonomic hand-held device for objectively quantifying muscle strength

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

All forty normal healthy children will undergo measurement of pressure pain tolerance via digital pressure algometry, balance assessment using HUMAC balance system, and evaluation lower limb strength using Lafayette Hand Held Dynamometer.

Pressure pain tolerance will be measured using pressure algometer for all participants in both groups. Pressure pain tolerance will be measured in a relaxed sitting position to evaluate on quadriceps muscle. Initially, a teddy bear will be used for demonstration.
HUMAC balance system will be calibrated, then will conduct 1. center of pressure: will instructed child to stand on platform, and maintain own body stability, and focus on the red dot in the center of screen that will move in response to body sway. after a rest, second trial will be done. 2. Eye open/ closed firm surface tests: First for Eye open firm surface test; the child will be asked to look at a target on the wall that was set at his/ her eye level, and to stare at this target for 30 seconds while standing on firm surface. After 5 seconds rest. Eye closed firm surface test; child will be asked to close his/ her eyes for 30 seconds, and conducting the same procedures for balance testing. The researcher will documented the values resented on the screen .
Lower limb muscular ' Isometric quadriceps strength' will be measured for all participants in both groups. each participating child will be instructed to sit to assess the strength of knee extension, which minimize positional changes, and enhance feasibility of this clinical test. then The researcher will apply resistance to child's quadriceps to gain maximal voluntary isometric contraction with pressing the activated Lafayette hand held dynamometer padded stirrup against quadriceps belly, then recorded and documented measured value.
Also known as: Isometric quadriceps strength'
Pressure pain tolerance
Pressure pain tolerance measured via digital pressure algometer. It determines the pressure amount could be tolerated over quadriceps. This will represented chronic pain among Sickle cell anemia children in order to aid in diagnosis of hyperalgesia thus provide insight into their management strategies. Digital pressure algometer determines enables the rater to quantify the mechanical sensitivity to pain and the recovery of underlying problems or soreness levels in a semi-objective manner.
Time frame: Baseline of the study.
Balance assessment
Balance assessed via HUMAC balance system to define musculoskeletal involvement in sickle cell anemia children. HUMAC balance system is an electronic balance board connected with laptop running HUMAC balance system software.
Time frame: Baseline of the study.
Lower limb muscle strength
Lower limb muscle (Quadriceps) strength evaluated via Lafayette hand held dynamometer to evaluate voluntary isometric contraction. Hand held dynamometer has a good to excellent reliability and validity mainly for proximal musculatures.
Time frame: Baseline of the study.
