It is especially essential for relaxation and contraction of muscles. Calcium is a trigger for the contraction of muscle. It aids in action potential formation, initiated at the motor end plate (Denegar et…

Another vital electrolyte in musculoskeletal function is Potassium. Its role is concerned with the neutralization of metabolic acids that deplete bone. Potassium salts taken into the body via fruits and vegetables yield Potassium bicarbonate via metabolism. Were these not to be taken in adequate amounts, they would lead to mineral compounds that alkalize bone being recruited from the bone, thus resulting in bone resorption, a possible cause for the patients need for a hip replacement. The resorption of bone to provide alkalization fluids leads to bone weakening (Denegar et al, 2004).
a) Osteocytes: These are star shaped cells of the bone that are surrounded by the bone matrix. They are mature forms of other bone cells called osteoblasts. They possess long branches from their main body that extend and connect to other adjacent osteocytes. They perform a crucial role in the maintenance of body fluids of Calcium ion levels. They carry this function out by regulating the resorption and formation of bone, thus controlling the amount of calcium in the body, since Calcium ions are essential components in the formation of bone. The bone is the human body’s major Calcium reservoir. Thus, these cells end up controlling Calcium levels. The patient could have a problem with osteoclast regeneration, thus leading to continued bone depletion (Dvořák, 2009).
b) Osteoblast Cells: These are primarily bone cells that form bone. They only possess one nucleus and are formed from other cells known as osteoprogenitor cells. They function via the production of osteoid, better known as the bone matrix. After secretion, the matrix is then, together with Phosphate and Calcium, mineralized to form bone (Dvořák, 2009). When these cells mature and stop producing bone, they become flat and line the bone surface. Here, they regulate the entry and departure of Calcium and

Work-related Musculoskeletal Disorders in Physiotherapists as a Risk Factor for Depression. The change in technology, strategy and other work related factors has led to the change in the functioning and subsequent demands of employees (Burnett, 2007). As work demands rises, there comes the rise in the risk factors employees expose themselves.
The main objective of ergonomics is to minimize injuries and stress linked to repetitive body movements, bad posture or muscle overuse. The assessment phase of ergonomics is often followed by the design phase, which seeks to develop tasks, controls, work areas, lighting and tools so as to fit the requirements of employees’ limitations and abilities.
Children suffering from scoliosis, juvenile rheumatoid arthritis and other musculoskeletal and orthopedic disorders need special care and certain changes to be incorporated at school to make it easier for them. Children suffering from scoliosis may be very conscious of their appearance and posture which might lead to the children having low self esteem or other psychological problems.
Enhanced view of the working points/surfaces is ensured by this design to allow for full concentration on the on the work by its operators since they can easily see the tip. The design is also equipped with a spotting lamp that further improves the
A 40 year old Asian-American male presents to the clinic with complaints of acutely worsening low back pain with numbness; as well as a tingling effect down his right leg to his toes as a result of lifting
The last four factors are closely interrelated in causing pain in the mid lumbar area. Lumbar disc complications such as degenerated discs can cause pain in the disc space. The pain eventually spreads to other lower parts such as buttocks,
