How does the density of a heavy plaster cast affect patient comfort on an upper limb?

Answer

It can fatigue the patient and alter their center of gravity noticeably

The physical presence and mass of a traditional, heavy plaster cast, especially when applied to an upper limb such as an arm or shoulder, introduces a significant mechanical burden on the patient. This added weight is substantial compared to modern lightweight alternatives, leading directly to muscle fatigue in the affected limb during daily activities. Furthermore, the significant alteration in mass distribution can noticeably shift the patient's overall center of gravity, requiring continuous compensatory effort from the patient to maintain balance and posture. This contrasts sharply with the significantly lighter fiberglass materials, which minimize this physical fatigue and disruption to normal body mechanics during the recovery period.
