Purpose: This study aimed to investigate the effect of angular joint mobilization (AJM) on the shoulder pain, range of motion, and functional improvement in a patient with shoulder adhesive capsulitis. Methods: The patient diagnosed with right shoulder adhesive capsulitis by an orthopedic surgeon was a 60-year-old male, right hand/arm dominant, with a height of 175 cm and weight of 75 kg. The patient received 12 sessions of AJM once or twice per week for eight weeks. AJM was applied for 5 min each of flexion, abduction, external rotation, internal rotation, for a total of 20 min per session. The visual analog scale, the goniometer, and the Oxford shoulder score were used to measure pain, range of motion, and shoulder pain & disability index, respectively. Results: After all the treatments, the pain decreased from 6 to 2 points. The range of motion increased in flexion by $54.3^{\circ}$ from $125^{\circ}$ to $179.3^{\circ}$, abduction by $38^{\circ}$ from $140^{\circ}$ to $178^{\circ}$, external rotation by $54.4^{\circ}$ from $30.3^{\circ}$ to $84.7^{\circ}$, and internal rotation by $25^{\circ}$ from $45^{\circ}$ to $70^{\circ}$. The shoulder disability index decreased from 33 points to 17 points. Conclusion: This study found that AJM has a positive effect on the improvement of shoulder pain, range of motion, and function in a patient with shoulder adhesive capsulitis. Further studies on AJM are needed in the future.

Objective: Joint mobilization for arthrokinematics altered by the positional fault of chronic ankle instability (CAI) is an effective intervention for stabilization. In this study, we compared the effects of ankle dorsi flexion range of motion (DFROM) and dynamic balance ability (DBA) in CAI patients via passive joint mobilization (PJM), a method traditionally performed in previous studies, and active joint mobilization (AJM), a method that can have a greater effect on cortical excitability with spontaneous movements. Design: Single-blind two-arm randomized controlled trial Methods: A total of 30 participants were registered: 15 each to the PJM and AJM groups. Each participant received a total of 10 intervention sessions, 10 minutes per session, 5 times a week for 2 weeks. PJM used Maitland's mobilization method to apply joint mobilization with talus in the posterior direction and AJM used an angular joint motion to induce patient's voluntary motion of medial malleolus anterior gliding and lateral malleolus posterior gliding, respectively. DFROM of the ankle was measured by using tape and DBA was evaluated by using the balance system. Results: Significant improvement was observed after intervention in both the PJM and AJM groups except for the DBA-anterior and DBA-right variables of the PJM group. There were statistically significant differences between the AJM and PJM groups in the DFROM, DBA-anterior, DBA-posterior, and DBA-right variables. Conclusions: The overall improvement of DFROM and DBA was found to be more effective in joint mobilization including voluntary movement. When it is accompanied by voluntary movement, it further affects the neuromuscular system of the ankle.

The purpose of this study was to analyze the shoulder joint torque and muscle pattern performing as Tennis serve by Isokinetic motions on Isomed 2000. The subject, who was 5 males Korean national high school tennis players. By analyzing the flexion/extension of the shoulder, the peak torque of the internal/external rotation motion(at 60,180 and 300 degree/sec) at peak torque degree, the weight, peak torque, and power. combined with the timing of the electrode of the attached trapezius and posterior deltoid at the three part. From the data analysis & discussion the following conclusions were drawn. When doing a shoulder extension, the peak torque can be widely seen at 60degree per second. However the degree may be different depending on angular velocity. When doing an internal rotation at 90degree abduction, peak torque per weight was seen at 60degree per second. The degree of peak torque was at 31.6-44.2 and peak power was faster when angular velocity was increased. The aspect of muscle pattern was seen more at the internal rotation in the 90degree abduction rather than the shoulder extension. However the angular velocity was not influenced by muscle mobilization(in order of anterior deltoid, posterior deltoid and trapezius. To properly apply the above conclusion, when tennis players serve it is better the elbow be impacted by the extension. when doing isokinetic motion it is better to increase angular velocity and improve muscle power. also the anterior deltoid amongst the shoulder muscle should be improved to develop serve speed.
