Torticollis, also known as wry neck, is a dystonic condition defined by an abnormal, asymmetrical head or neck position, which may be due to a variety of causes. 

The most common case has no obvious cause, and the pain and difficulty with turning the head usually goes away after a few days, even without treatment

​They are innervated by the fourth, fifth, and sixth cervical spinal nerves (C4-C6).
The anterior and middle scalene muscles lifts first rib and bends the neck to the same side;
the posterior scalene lifts the second rib and tilts the neck to the same side.

Tennis elbow, also known as lateral epicondylitis, is a condition in which the lateral part of the elbow becomes painful and tender. The pain may also extend into the back of the forearm and grip strength may be weak. The onset of symptoms is generally gradual. ​If left untreated lateral epicondylitis can lead to chronic pain that degrades the quality of daily living.

There is a functional relationship between the structure of the arch of the foot and the biomechanics of the lower leg. The arch provides an elastic, springy connection between the forefoot and the hind foot. This association safeguards so that a majority of the forces incurred during weight bearing of the foot can be dissipated before the force reaches the long bones of the leg and thigh.

The term ‘frozen shoulder’ is often loosely used and wrongly attributed to other shoulder limitations such as a rotator cuff tear or osteoarthritis. Clients with frozen shoulder typically experience shoulder stiffness, severe pain that usually worsens at night, and near-complete loss of passive and active external rotation of the shoulder.[1]

​The condition known as piriformis syndrome refers to sciatica symptoms not originating from spinal roots and/or spinal disc compression, but involving the overlying piriformis muscle.
​
Causes may include trauma to the gluteal muscle, spasms of the piriformis muscle, anatomical variation, or an overuse injury. 

Bursa’s helps to cushion bones, tendons, and muscles that are close to joints.  A bursa is a small fluid-filled sac, lined by a synovial membrane with an inner capillary layer of viscous synovial fluid.  Bursitis, as the name suggests, is an inflammation of this sac.  Bursitis is known to be a very painful condition.
The most common parts of the body affected by bursitis include the shoulders, elbow, and hips. However, bursitis can also be found in some other parts of the body such as knee, heel, thumb, and the ischial tuberosity 

Sciatica is a medical condition characterised by pain going down the leg from the lower back.[1] This pain may go down the back, outside, or front of the leg.[3] Onset is often sudden following activities like heavy lifting, though gradual onset may also occur.[5] Typically, symptoms are only on one side of the body.[3] Certain causes, however, may result in pain on both sides.[3] Lower back pain is sometimes but not always present.[3] Weakness or numbness may occur in various parts of the affected leg and foot.[3]
