Background: Healthcare workers are the most common category of population exposed to work
related musculoskeletal disorders causing prolonged postural abnormalities and pain which
negatively affects productivity and quality of life.
Purpose: To compare and assess the correlation between thoracic kyphosis angle and shoulder
ROMs, proprioception and function among healthcare workers in two different age groups (30-
39) years old and (40-49) years old.
Material and methods: Study design is cross-sectional, observational and comparative study.
Forty-five participants of both gender with thoracic kyphosis detected by screening
measurements at the start. Their ages ranged from 30-49 years old and their thoracic kyphotic
angle (TKA) ranged according to age into 2 groups; group (A) 16 participants their ages from
(30-39) years old and include participants with TKA was more than 29.04 degree in male and
28.42 degree in female while group (B) their ages from (40-49) years old and include
participants with TKA was more than 29.75 degree in male and 32.66 degree in female.
A bubble inclinometer was used to measure both thoracic kyphotic angle, shoulder ROMs and
joint position sense (JPS) of dominant arm among healthcare workers. Shoulder Pain and
Disability Index (SPADI) was used to assess shoulder function. Unpaired t test compared TKA
and shoulder ROMs, proprioception and function between groups. Also, Pearson correlation
coefficient correlation was made to obtain the relation between the TKA, shoulder ROMs,
proprioception (JPS), pain intensity and function activities.
Results: No significant difference in shoulder adduction, external and internal rotation ROM
between groups at (p > 0.05). A significant difference in TKA, shoulder flexion, abduction JPE,
shoulder pain and disability were detected between groups at (p<0.05). A significant difference
in shoulder flexion, extension and abduction ROM was detected between groups at (p<0.05). A
moderate negative correlation between TKA and shoulder flexion, abduction, external rotation
ROM was detected. There was no correlation between TKA and shoulder extension, adduction
and internal rotation ROM (p > 0.05). There was a moderate positive correlation between TKA
and flexion, abduction JPE, pain and function activities.
Conclusion: it was concluded that kyphosis angle was correlated with many of shoulder
movements, proprioception and function. Therefore, dorsal spine assessment could be considered
during evaluation of shoulder joint and vice versa. So better control of the symptoms and better
plan of treatment for preventing the potential disabling condition.

تم اختيار 45 مشاركا من كلا الجنسين مصابين بالحداب الصدري عن طريق قياسات الفحص في البداية. تراوحت أعمارهم بين 30-49 سنة وتراوحت زاوية الحداب الصدري (TKA) وفقا للعمر إلى مجموعتين. المجموعة (أ) 16 مشاركا تتراوح أعمارهم بين (30-39) سنة وتشمل المشاركين مع TKA كان أكثر من 29.04 درجة في الذكور و 28.42 درجة في الإناث بينما المجموعة (ب) أعمارهم من (40-49) سنة وتشمل المشاركون مع TKA أكثر من 29.75 درجة في الذكور و 32.66 درجة في الإناث.تم استخدام مقياس ميل الفقاعة لقياس كل من زاوية الحداب الصدري و المدى الحركى للكتف وإحساس موضع المفصل (JPS) للذراع المهيمنة بين العاملين في مجال الرعاية الصحية. تم استخدام مؤشر آلام الكتف والإعاقة (SPADI) لتقييم وظيفة الكتف. قارن اختبار t غير المزاوج زاوية الحدداب الصدرى(TKA) و المدى الحركى للكتف ، واستقبال الحس العميق والوظيفة بين المجموعات. أيضا ، تم إجراء ارتباط معامل ارتباط بيرسون للحصول على العلاقة بين TKA ، ROM الكتف ، استقبال الحس العميق (JPS) ، شدة الألم والانشطة الوظيفية للكتف
