instability. 30 So far, no researcher has compared the effect of muscle fatigue on the shoulders of subjects with GJH and nonhypermobile individuals. Acromiohumeral distance (AHD) is the linear measurement of the subacromial space outlet and is measured by ultrasonography. 31 – 33 Ultrasonography

Compromise to the acromiohumeral distance (AHD) has been reported in subjects with subacromial impingement syndrome when compared with healthy subjects. In clinical practice, patients are taped with the intention of altering scapular position and influencing the AHD. However, research to determine the effects of taping on AHD is exiguous.
To evaluate the effect of ridged taping techniques to increase posterior scapular tilt and upward scapular rotation on the AHD.
1-group pretest/posttest repeated-measures design.
Human performance laboratory.
20 asymptomatic participants (10 male and 10 female) age 27 y (SD 8.0 y).
Ridged tapping of the scapula into posterior tilt and upward scapular rotation.
Main Outcome Measure:
Ultrasound measurement of the AHD.
AHD increased significantly after rigid tape application to the scapula (P < .003) in healthy shoulders in 60° of passive arm abduction.
Taping techniques applied to the scapula had an immediate effect of increasing the AHD in healthy shoulders in 60° of passive arm abduction. Results suggest that taping for increasing posterior scapular tilt and increasing scapular upward rotation can influence the AHD and is a useful adjunct to rehabilitation in patients with subacromial impingement syndrome.

The supraspinatus muscle has an important role in the stabilization of the glenohumeral joint. Identifying abnormalities concerning its size and the subacromial space in the presence of pain may be relevant to provide more specific treatments focused on the etiology of pain.
To determinate whether painful shoulder causes changes in the supraspinatus cross-sectional area (CSA) and the acromio-humeral distance (AHD) between overhead athletes.
University campus and local sports clubs’ Physical Therapist room.
81 male overhead athletes were divided into 2 groups according to the presence of shoulder pain and clinical symptoms.
Main Outcome Measures:
Ultrasonography measurements of the supraspinatus CSA and the AHD in 2 groups of overhead athletes with and without pain.
In the pain group, the CSA was significantly smaller compared with the no pain group. No differences between groups were found in the AHD measurement.
Shoulder pain in overhead athletes was associated with a reduction in their supraspinatus muscle CSA, but not in the AHD. These findings suggest that muscle atrophy exists in the presence of pain. However, in active overhead athletes, the AHD is not clearly reduced in overhead athletes with shoulder pain. Further studies are needed to understand this condition.

shuttlecock speed was measured for each of the 20 smashes. Then, the mean speed was calculated by averaging the 20 speed values. Precision The evaluation of precision was assessed by using a video camera (AHD-H12 VAZ2S; Aiptek, Taiwan) for postprocessing analysis. The camera was located 5 m behind the
