This study investigated the effect of a 12-week rehabilitation program on the range of motion (ROM) and muscle strength of high school baseball players with shoulder instability. We allocated 12 players with shoulder instability to the rehabilitation group and 13 players without shoulder instability to the normal exercise group. Covariate analysis (ANCOVA) was performed to assess the ROM of the internal (IR) and external (ER) rotational joints before and after participating in the 12 weeks of rehabilitation, and two-way ANOVA was performed to assess isokinetic muscle strength. The statistical significance level was set at p<.05. The IR ROM of the dominant (D) shoulder with instability and non-dominant (ND) shoulder was significantly increased before and after the rehabilitation program. The total ROM of the D shoulder with instability significantly increased after rehabilitation. IR isokinetic strength significantly improved at an angular velocity of 180°/s after rehabilitation. These results indicate that the rehabilitation program used in this study could be effective in improving ROM and muscle strength in patients with shoulder instability. However, due to the limited results, additional research on the premise of extending the rehabilitation period is necessary.

Objective : This study examines whether functional motion is present at one or more years after Bioflex System placement. BioFlex System is a flexible rod system which has been used to preserve motion at the area of implantation. There has not been a scientific study showing how much motion is preserved after implantation. Methods : A total of 12 consecutive patients underwent posterior dynamic stabilization using the BioFlex System. Six patients were treated using a L3-4-5 construct and other six patients using a L4-5-S1 construct. Follow-up ranged from 12 to 33 months and standing neutral lateral, extension, flexion and posteroanterior (PA) radiographs were obtained at 3, 6, 9, and 12 months and at more than 12 months postoperatively. Range of motion (ROM), whole lumbar lordosis, and ROMs of motion segments from L2 to S1 were determined. Results : Patients with a L3-4-5 construct demonstrated a decrease in mean ROM for whole lumbar decreased from 40.08 to 30.77. Mean ROM for L3-4 (6.12 to 2.20) and L4-5 (6.55 to 1.67) also decreased after one year. Patients with a L4-5-S1 construct demonstrated L4-5 (8.75 to 2.70) and L5-S1 (9.97 to 3.25) decrease of mean ROM at one year postoperatively. Lumbar lordosis was preservep at both L3-4-5 and L4-5-S1 constructs. Clinical results showed significant improvements in both study groups. Conclusion : The present study provides preliminary information regarding the BioFlex motion preservation system. We conclude that the BioFlex System preserves functional motion to some degree at instrumented levels. However, although total lumbar lordosis was preserved, ROMs at implantation segments were lower than preoperative values.

PURPOSE: This study investigated the influence of a specific hip joint exercise program on the characteristics of chronic low back pain (LBP), hip joint range of motion (ROM), and performance level in amateur golfers with LBP. METHODS: The study included 28 adult male amateur golfers with LBP and reduced internal rotation (IR) of the lead side hip joint. Subjects were randomly assigned to an experimental (EG) (n=14) or control group (CG) (n=14). The Numerical Rating Scale score for pain, ROM of the hip joint and trunk rotation, performance parameters for golfing were evaluated. A specific exercise program designed to improve IR of the lead side hip joint was performed by the EG, but not the CG. Post-intervention evaluation was performed and the collected data were analyzed. RESULTS: After the intervention, the severity of LBP was significantly reduced (p<.05) and the IR ROM of the lead side hip joint was significantly increased (p<.01) in the EG. Moreover, the trunk rotation range was significantly increased in the EG (p<.01). The drive distance was significantly difference between the EG and CG (p<.05). CONCLUSION: A specific hip joint exercise program can help to reduce pain level and improve performance level in amateur golfers with LBP and increased IR ROM of the lead side hip joint. A significant increase in ROM of the lead side hip joint reduce LBP and was related to driving distance in the EG.

The purpose of this study was to investigate the effect of taping therapy on activities of daily livings (ADL), hand function and range of motion in poststroke-hemiplegic patients. Sample were selected from 20 poststroke-hemiplegic patients at public health center in the period from September 5 to November 21, 2001. The research design was one group pretest-posttest design. The hemiplegia period of the participants was from one year to five years. The pretest and posttest included measuring activity of daily livings(ADL), instrumental activity of daily livings(IADL), hand function, range of motion, quality of life. In this research design, a treatment were to expose taping therapy who were received self-help management program. This self-help management program was composed of five sessions and each session had health education on stroke, diet, risk factor, ROM exercise and recreation. 20 patients were treated with kinesio taping(Nippon Sigmax Co., Ltd., Benefact(r), width 50mm). Tapes were applied to the Deltoid, Supraspinatus, Infraspinatus, Brachioradialis with paralyzed upper extremity. The taping therapy was performed once a week for 5 weeks. SPSS Win 8.0 was used for the data analysis. The results of this study were as follows: 1) The score of BADL was increased from 30.5 to 33.95 after program, and that was statistically significant(p=.019). 2) The score of IADL was increased from 11.6 to 12.75 after program, but that was statistically insignificant(p=.161). 3) The score of hand function was increased from 17 to 20.35 after program, and that was statistically significant(p=.026). 4) The shoulder's ROM(p=.000) and wrist's ROM(p= .004) were significantly increased. According to the results of this study, taping therapy is effective for improving ADL, hand function, ROM, quality of life. However, this study found no significant differences in IADL. Consequently, these findings showed that the taping therapy was effective in improvement of physical aspects(BADL, hand function, upper extremity's ROM) in poststroke-hemiplegic patients.

Background: Limitations of shoulder range of motion (ROM), particularly shoulder internal rotation (SIR), are commonly associated with musculoskeletal disorders in both the general population and athletes. The limitation can result in connective tissue lesions such as superior labrum tears and symptoms such as rotator cuff tears and shoulder impingement syndrome. Maintaining the center of rotation of the glenohumeral joint during SIR can be challenging due to the compensatory scapulothoracic movement and anterior displacement of the humeral head. Therefore, observing the path of the instantaneous center of rotation (PICR) using the olecranon as a marker during SIR may provide valuable insights into understanding the dynamics of the shoulder joint. Objects: The aim of the study was to compare the displacement of the olecranon to measure the rotation control of the humeral head during SIR in individuals with and without restricted SIR ROM. Methods: Twenty-four participants with and without restricted SIR ROM participated in this study. The displacement of olecranon was measured during the shoulder internal rotation control test (SIRCT) using a Kinovea (ver. 0.8.15, Kinovea), the 2-dimensional marker tracking analysis system. An independent t-test was used to compare the horizontal and vertical displacement of the olecranon marker between individuals with and without restricted SIR ROM. The statistical significance was set at p < 0.05. Results: Vertical displacement of the olecranon was significantly greater in the restricted SIR group than in the control group (p < 0.05). However, no significant difference was observed in the horizontal displacement of the olecranon (p > 0.05). Conclusion: The findings of this study indicated that individuals with restricted SIR ROM had significantly greater vertical displacement of the olecranon. The results suggest that the limitation of SIR ROM may lead to difficulty in rotation control of the humeral head.

PURPOSE: The purpose of this study was to compare the effects of cross-body stretching (CBS) and modified cross-body stretching (MCBS) on the range of motion (ROM) of glenohumeral joint (GHJ) in healthy subjects. METHODS: Thirty subjects were randomly assigned to 1 of 2 groups: CBS group without stabilization of scapula (n=15) and MCBS group with stabilization of scapula (n=15). We measured horizontal adduction and internal rotation ROM of GHJ in pre- and post-intervention. The data were analyzed using the analyses of covariate (ANCOVA) and least significant difference (LSD) post hoc tests (p=.05). RESULTS: In the post-intervention, the MCBS group had a significantly greater increase in horizontal adduction ROM (mean ${\pm}$ SD, $11.46^{\circ}{\pm}0.83^{\circ}$) compared to the CBS group ($7.81^{\circ}{\pm}0.83^{\circ}$) (p=.007) and a greater increase in internal rotation ROM ($62.27^{\circ}{\pm}0.74^{\circ}$) compared to the CBS group ($59.20^{\circ}{\pm}0.74^{\circ}$) (p=.004). CONCLUSION: A single session application of an MCBS provides immediate more improvements in both horizontal adduction and internal rotation ROM than CBS. These results suggest that application of MCBS with stabilization of scapula may be a more useful to gain ROM of GHJ than CBS without stabilization of scapula.

Purpose : The purpose of this study was to compare the influence of Contract-Relax Technique of PNF(Proprioceptive Neuromuscular Facilitation) and taping treatment on the ROM(Range of Motion), pain and gait speed of osteoarthrits of knee. Methods : In this study K hall for the aged were selected. Twenty-six subjects with osteoarthrits participated in the experiment. The subjects were partitioned into two groups are 13person PNF group and 13person taping group. All subjects randomly assigned to the PNF treatment group and taping treatment group. Both group received treatment for 3times a week during 4 weeks. (PNF group received treatment for twenty times at once). Algometer and VAS(Visual Analogue Scale) were used to measure pain, the ROM was meaured using goniometer and gait speed was measured using a stopwatch (30m-test). All measurements of each subject were measured at pre-treatment and post-treatment. The data were analyzed with SPSS WIN 11.5 using t-test. Results : The PNF group had a significantly increase of knee extension ROM and significantly decrease of pain after treatment 4 weeks(P<0.05). The taping group had a significantly increase of knee extension ROM and gait speed and significantly decrease of pain after treatment 4 weeks(P<0.05). Conclusion : These data suggests that PNF is beneficial to increase knee extension ROM and to decrease pain. Taping is beneficial to increase knee extension ROM and gait speed and to decrease of pain.

Background: Forward head posture (FHP) causes various posture imbalances associated with the head and neck. Myofascial release is an effective treatment method used for relaxing muscles and reducing muscle hyperactivity, but no studies have been conducted on suboccipital and neck muscles related to FHP. Objects: The purpose of this study was to investigate the immediate effect of roller massages on the cranio-cervical flexion (CCF) range of motion (ROM) and CCF strength applied to suboccipital and neck muscles in subject with forward head posture. Methods: Twenty-four FHP subjects (male: 13, female: 11) were recruited for this study. All subjects were recruited with a craniovertebral angle (CVA) of 53 degrees or less and a head tilt angle (HTA) of 20.66 degrees or higher. CCF strength was measured using Pressure biofeedback unit (PBU) in the supine posture and CCF ROM was measured using smartphone-based inclinometer. Roller massage (RM) was applied to suboccipital and neck muscles for 2 minutes and CCF ROM and strength were remeasured. Results: These results of this study showed that CCF ROM was a significant difference in CCF ROM before and after RM (p < 0.05). CCF strength also showed a significant difference before and after RM (p < 0.05). Conclusion: RM method might be recommended to increase the immediate ROM and strength of CCF in subjects with forward head posture.

Background: The purpose of this study was conducted to investigate the effects of the ankle mobilization with movement (MWM) technique on ankle dorsiflexion range of motion (ROM), balance, and gait in patients who underwent total knee replacement (TKR). Methods: Thirty patients with knee osteoarthritis were recruited and randomly divided into two groups: the experimental group (EG; n=15) and the control group (CG; n=15). For five days a week for 3 weeks, participants in the EG were treated with the ankle MWM technique and traditional total knee replacement (TKR) exercise, and those in the CG only performed traditional TKR exercises. The dorsiflexion ROM, balance, and gait of the patients were before and after exercise. Results: Balance system SD was used compare changes in dynamic balance. Patients in the EG group showed statistically significant differences after the intervention (p<.05). In addition, there was a statistically significant difference in dynamic balance between the EG and CG groups after the intervention (p<.05). STT-IBS was used to compare changes in velocity, step length, stride length, and ankle dorsiflexion ROM. Patients in the EG group showed statistically significant differences after the intervention (p<.05). In addition, there was a statistically significant difference in the velocity, step length, stride length, and ankle dorsiflexion ROM between the EC and CG groups after the intervention (p<.05). Conclusion: Our results showed that applying the ankle MWM technique with traditional TKR exercises improved ankle dorsiflexion ROM, dynamic balance, and gait in patients.
