Question

Kemar is a swimmer who has begun complaining of pain and feelings mimicking shoulder dislocations when practising his freestyle stroke in training. He complains of discomfort with overhead tasks that worsens as he maintains the position. His coach has recommended that he see the team physician, however he is convinced that his problem is solely due to new patterns in his movement.  

1. In three steps, define a freestyle stroke specific to the movement occurring at the shoulder joint and in the shoulder complex. Include in your answer the muscles working to afford those motions.

2. What are the specific movements from the freestyle stroke phases that would be some likely causes for Kemar experiencing frequent dislocations during training season? Make specific reference to the anatomy in your answer.
3. If Kemar’s shoulder dislocation continues to go unchecked, what would be some likely effects on his movement occurring at the shoulder joint and in the shoulder complex? Make specific reference to the anatomy in your answer.
4. Kemar eventually visits the team’s physician and has been diagnosed with shoulder dislocation. If you were Kemar’s coach, what specific adjustments would you make to his training plan in collaboration with the team physician that would facilitate or assist in the rehabilitation of his shoulder injury? Please explain why you made the adjustments making specific reference to the anatomy in your answer.

Answer 1

In freestyle stroe swimming whne your hand enter the water in line with the shoulder glides forward the water. shoulder rotates downward during down sweep continuous downward and backward pressure in the hand and forearm make the shoulder rorate forward. the shoulder should be back during freestyle stroke and when the arm move formards for 90degree forward in a flexed position. mucle inlvoed in freestyle stroke shoulder movement inlcude large muscles groups like trapezipus, Quadricpes, harmstring,biceps, triceps, deltoid, rotator cuff and various core muscles.
a, Glenohumeral subluxation is a partial or incomplete dislocation that occurs from changes in the integrity of the joint. Humeral head slips out of the glenoid cavity that weakens the rotator cuff. Arm movement with poor flexibility and rotate of the shoulder causes dislocation. joint capsule stretches cause subluxation.
b, It causes shoulder instability, loss of movement, shoulder injury, nerve damage if it is untreated. shoulder joint with arm bone connection of humorous and glenoid dislocation cause completely pull the bone out of the socket that causes instability result with recurring subluxation.injury to circumflex axillary nerve cause weakness of deltoid muscles and restrict movement in the shoulder.
c, Physical therapy, and athlete training service assist patients for the rehabilitation of shoulder injury. gentle traction of the arm and sling for several weeks immobilize the shoulder. physical therapy increases the shoulder flexibility and restores the range of motion, it strengths the shoulder muscles and prevents future shoulder dislocation. rehabilitation exercise strengthens the muscles, the trace can be used to prevent a recurrence.
