The carpal tunnel functions as an entrance to the palm for many tendons and median nerve (1). The median nerve is one of the five branches that make up the brachial plexus. This nerve provides motor innervation to the flexor muscles of the forearm and hand as well as muscles responsible for movements of the thumb. It also provides sensory innervation to the volar aspects of the first three digits and half of the fourth digit, the palm, and the medial region of the forearm (2). Carpal tunnel syndrome (CTS) is a common painful disorder of the wrist and hand. Pain or other symptoms (numbness, tingling, and weakness) arise as the median nerve is compressed (3). The cause is not always found to be within the carpal tunnel (4). Compression …show more content…
Poor posture paired with overuse of the hands and wrist are frequently found in patients with carpal tunnel syndrome (4). Postural dysfunction is common many different occupations. Proper ergonomics aims to suit the job to each individual. Ergonomics in the work place are often not customized for each individual. This forces employees to work in sub-optimal conditions. A common posture that individuals adapt under these conditions is “postural depression.” Postural depression consists of a hunched back with a forward position of the head and shoulders. Poor postures increase the likelihood of individuals developing trigger points in these areas. Trigger points associated with symptoms of carpal tunnel syndrome are located in the coracobrachialis, biceps brachii, and subscapularis muscles. “Postural depression” also increases the likelihood adopting a “chest breathing” pattern. Chest breathing increases the susceptibility of developing trigger points in the scalene muscles. The scalene muscles plays a role in elevation of the first two ribs during upper chest breathing. This muscle has the potential to influence carpal tunnel syndrome due
