2.Reliability of Measuring Leg Segments and Joint Angles Using Smartphones during Aquatic Exercise
Healthcare Informatics Research 2022;28(1):95-101
Objectives:
Aquatic therapy is a significant intervention method for both patients and healthy individuals. However, in clinical practice, quantitative measurements are rarely applied in aquatic therapy due to the disadvantages of submerging expensive instruments in water. In this study, we used readily available smartphones and armbands to measure leg segments and joint angles during aquatic gait and evaluated the reliability of these measurements.
Methods:
Waterproof smartphones were strapped to the trunk, thighs, and shanks of 19 healthy young adults using armbands. The angles of the trunk, thigh, and shank segments were measured during aquatic gait. The measurements were repeated 1 day later. The data were analyzed to obtain the angles of the hip and knee joints.
Results:
Measurement repeatability, calculated using the intraclass correlation coefficient (ICC), was the highest for the shank segment range of motion (ROM) (first 46.79° ± 5.50°, second 50.12° ± 9.98°, ICC = 0.78). There was high agreement in trunk segment ROM (first 6.36° ± 1.42°, second 4.29° ± 1.83°, ICC = 0.73), thigh segment ROM (first 33.49° ± 5.18°, second 37.31° ± 8.70°, ICC = 0.62), and knee joint ROM (first 52.43° ± 11.26°, second 62.19° ± 16.65°, ICC = 0.68) and fair agreement in hip joint ROM (first 34.60°±4.71°, second 37.80° ± 7.84°, ICC = 0.59).
Conclusions
Smartphones can be used to reliably measure leg segments and joint angles during aquatic gait, providing a simpler method for obtaining these measurements and enabling the wider use of aquatic motion analysis in clinical practice and research.

OBJECTS: The purpose of this study is to estimate the values of foot pressure of the stance phase during a gait cycle in hemiplegic gait. METHOD: Thirty patients who had a stroke and forty healthy adults were evaluated by the EMED-SF system to analyze the stance phase of hemiplegic gait. The stance phase was evaluated by 6 points according to the foot pressure and center of pressure proposed by Lee et al.2) RESULTS: 1) In hemiplegics, the stance time of involved limb decreased compared with that of the uninvolved limb and increased that of control groups (p<0.05). 2) In hemiplegics, the midstance time increased but the loading response and terminal stance decreased compared with the uninvolved limb and controls (p<0.05). 3) In hemiplegics, the midstance time decreased and the loading response and terminal phase increased according to the increased Brunnstrom stage (p<0.05). CONCLUSION: The results showed that an analysis of stance phase by the measurement of plantar pressure was a valuable parameter in the gait analysis of hemiplegic patients.

OBJECTIVES: To learn which inhibition of nitric oxide synthase with L-nitro arginine methylester(L-NAME) induces a preeclampsia-like syndrome in pregnant rabbits and high dose of L-arginine reverse the adverse changes induced by nitric oxide synthesis inhibition in pregnant rabbits. MTERIAL AND METHOD: Twenty Newzealand rabbits with 22-days of gestation were injected subcutaneously with 400mg of L-NAME for 7days and 100mg/kg L-arginine was also given intravenously 10 of 20 L-NAME injected pregnant rabbits. They are compared with the control group in which same volume of saline was subcutaneously injected to 5 rabbits with same condition. They were anesthesized by ketamine 50 mg/kg and roupum 2 mg/kg intramuscularly. Cutdown of femoral artery was performed and 22 gauge angioneedle was inserted. On manometer,three way catheter was connected, zeroed with saline, and blood pressure was read. Blood samples were taken from the vein of ear and checked for count of blood cells and bood chemistry (BUN/Cr, GOT/GPT, LDH, Uric acid). Urine protein was measured with nelaton catheterized urine. We injected drugs for 7 days begining on 22 days after mating and performed cesarian section to deliver fetus. To observe their effects on organs, lung, liver, placenta and kidney were taken and fixed with formalin. The sliced kidney tissue in thickness of 1 mm, was fixed with glutaraldehyde for electron microscopy and stored at 4degree C. Special staining was done for closed observation of pattern changes. For statistical analysis, mean+/-SEM was used. The control and experimental groups were compared by unpaired t-test and the differences were significant if probability level is less than 0.05(<0.05). RESULT: Mean blood pressure(MAP) in the experimental group I was significantly high compared to the control group(P<0.05). There was no significant differences in MAP between experimental group II and control group. Urine Protein, BUN, Cr, GOT/GPT, LDH, platelet count in the experimental group I was significantly high(p<0.05) compared to the control group. There was no significant difference between experimental group II and control group. In light microscopic examination, lung, liver, kidney, placenta showed specific finding in experimental group I. Misconstructive of glomerulus in the experimental kidney was well preserved under EM examination. Interstitium of kidney was widened by increase of mesangial matrix. Mild effacement of foot process and cytoplasm of proximal tubule containing electron dense myelin figure like structure were observed. CONCLUSION: Long term injection of L-arginine analogue produced preeclampsia like syndrome and pathologic changes of organ system in pregnant rabbits. Concurrent high dose of L-arginine reversed such chages.

OBJECTIVE: The purpose of this study is to evaluate the effects of a self-stretching exercise on the pressure threshold of myofascial trigger point. METHOD: We examined the changes of pressure threshold in 66 patients with myofascial trigger points before and after a self-stretching exercise of shoulder girdle and also tested the visual analogue scale (VAS) of the subjective pain intensity. The self-stretching exercise of shoulder girdle includes a stretching exercise of four muscles in shoulder girdle simultaneously, including upper trapezius, levator scapulae, infraspinatus, rhomboideus major and minor, which is followed by 1) a sitting position, relaxed, 2) lateral bending of neck to contralateral side, 3) forward and downward stretching of ipsilateral arm with protrusion of scapula and internal rotation of arm maximally to the contralateral foot. Each stretching motion is maintained for 30 seconds. RESULTS: The results of the patients experiencing unilateral or bilateral myofascial neck and shoulder pain showed that the pressure threshold of trigger point increased in response to the self-stretching exercise as assessed by a pressure algometer. Also visual analogue scale (VAS) decreased in response to the self-stretching exercise. CONCLUSION: We conclude that the self-stretching exercise of shoulder girdle is an effective method for the simultaneous stretching of upper trapezius, levator scapulae, infraspinatus, rhomboideus major and minor.

We report a rare case of adenoid basal carcinoma in uterine cervix. The patient was a 43-year-old Korean female. She received neoadjuvant chemotherapy with Quick Cis-VP16 (cisplatin and VP16 with 7-10 days interval), three times and radical hysterectomy with pelvic lymph nodes dissection under the diagnosis of cervical cancer stage IIa. After the neoadjuvant chemotherapy, the mass size was 3 x 2.5 Cm and which was protruded in exocervical region. Microscopically, scattered small nests of uniformed small cells with dark nuclei and scant cytoplasm were observed. Peripheral palisading as well as the formation of gland-like or acinar structures were noted. There were also foci of squamous differentiation in same portion of the small nests. The epithelial surface in other portions showed squamous cell carcinoma, large cell non-keratinizing cell type. Distribution between adenoid basal carcinoma of the cervix and other disease, such as adenoid cystic carcinoma and squamous cell carcinoma with basaloid features, is important for clinical management because the clinical behavior of adenoid basal carcinoma is less malignant than adenoid cystic carcinoma.

Nevus sebaceous (NS) is a congenital hamartomatous disorder of the skin and its adnexa, usually involving the scalp or the face. It characteristically evolves and changes morphology with time. Various benign and malignant neoplasms can develop in association with NS. Most common benign or malignant tumors developed within the NS are syringocystadenoma papilliferum and trichoblastoma or basal cell epithelioma. We now report a case of NS associated with sebaceous adenoma, basal cell epithelioma, and eccrine poroma in a 63 year old male.
