EFFECT OF PNF STRETCHING VERSUS SELF STRAP STRETCHING ON ANKLE DORSIFLEXION RANGE OF MOTION AMONG COLLEGIATE ATHLETES WITH CALF MUSCLE TIGHTNESS.

BACKGROUND: Calf muscle tightness is a very common occurring condition in athlete. Stretching is form of physical exercise in which a specific muscle or tendon (muscle group) is deliberately flexed or stretched in order to improve the muscle's elasticity and achieve comfortable muscle tone. Flexibility helps with injury prevention, reduction of soreness following a workout, and a general sense of well-being. There are different stretching technique and protocol for improvement in calf extensibility and flexibility. The purpose of this study was to investigate the effectiveness of two techniques PNF and SELF STRAP STRETCHING for improving calf flexibility among collegiate athletes. MATERIALS AND METHOD: The selected 30 college athletes were randomly allocated to 2 groups equally. Group1 (n= 15) were given PNF and Group2 (n=15) were given self-strap stretching technique. Calf flexibility for each group was measured using goniometer and knee to wall test.Treatment was given for four days a week for 4 weeks. RESULT: The collected values were analyzed using paired 't' test and independent 't' test. The result showed an increase in the values of goniometric measurement and knee to wall test of the PNF technique (group A) compared to baseline value of self-strap stretching (group B) 16.4 and 10.88 at the end of 4 weeks. CONCLUSION: This study concluded that PNF technique is found to bemore effective in improving the calf muscle among collegiate athletes.

Comparative study of different operative approachs for the treatment of upper thyroid gland / 中国实用外科杂志

OBJECTIVE: To explore the feasibility of different operative approaches for the treatment of upper thyroid gland. METHODS: The clinical data of 87 patients underwent lobectomy in Department of Oncological Surgery, the First Affiliated Hospital of Bengbu Medical College from January 2016 to December 2018 were analyzed retrospectively.Preoperative ultrasound was used to evaluate the location of the tumor in the upper thyroid gland or thyroid gland hypertrophy.According to the operative approach,87 cases were divided into two groups including 42 cases of the cricothyroid approach and 45 cases of viacervical strap muscles approach. The intraoperative exposure of superior laryngeal nerve and postoperative complications of superior laryngeal nerve function and parathyroid gland were compared. RESULTS: Compared with the superior laryngeal nerve finding rate(83.3%)in the cricothyroid approach,the superior laryngeal nerve finding rate was higher(95.6%)(P0.05). CONCLUSION: The viacervical strap muscles approach compares the cricothyroid approach to the laryngeal nerve with a high rate of finding and a short searching time. Applying viacervical strap muscles approach in the case of an upper thyroid tumor and glandular hypertrophy helps to expose the upper pole and protect the external nerve branch of the larynx.

Crash helmet – the harbinger of death: a case report.

In one of the rarest form of freak accident, a young woman surrendered to her death in a manner that belie the reality only to be played back in a slow motion sequence. History is replete of instances in which death struck individuals in otherwise innocent forms. In this case – elaborated below – a helmet tucked under the crook of an elbow became the undoing causing the woman to topple backward in a slow-motion, the head striking the hard surface of the road and precipitating her death later in a hospital.

Effectiveness of hallux valgus strap: A prospective, randomized single-blinded controlled trial.

Objective: To study the effect of night-time hallux valgus strap usage on decreasing the progression of hallux valgus angle. Methods: Patients, who were older than eighteen years old with moderate to severe degree of hallux valgus, were randomized into 2 groups: the study group (prescribed to use night-time hallux valgus strap for 8 hours per night for 12 months), and the control group. Patients in both groups were advised to have proper foot care with proper shoes. Results: There were 25 patients in the study group and 22 patients in the control group. No statistical difference was found in demographic data between both groups. The hallux valgus angle, which was obtained through radiographic measurement, was decreased in both groups. However, there were no statistically significant differences in the decrease of hallux valgus angle between the two groups (p>0.05). Conclusion: Prescribing to use night-time hallux valgus strap for 12 months cannot decrease the progression of the hallux valgus angle more than the control group.

Objective To explore the efficacy of a new elastic suspension strap orthosis, designed by the authors, in improving the motor function and walking ability of stroke patients. Methods Thirty-nine stroke pa-tients less than 1 month after stroke were recruited and divided randomly into a treatment group and a control group. The patients in the treatment group accepted walking training with the assistance of an elastic suspension strap orthosis, 5 times a week for 8 weeks, while the control group accepted the same training without the assistance of the elastic suspension strap orthosis. Results The treatment group improved significantly more than the control group with regard to its average Fugl-Meyer score, the functional ambulation categories of its members, and their walking speeds. Conclusions The elastic suspension strap orthosis could help correct abnormal gait patterns, improve walking speed, and enhance the recovery of walking ability in stroke patients.

Three Newly Designed Arm Slings for the Stroke Patient with Shoulder Subluxation: A case report

We reported three types of newly designed arm slings (the "V" strap pouch arm sling, the Modified hemisling, the Tripod arm sling). The three slings and the conventional hemisling were all tested by a single stroke patient for the correction of shoulder subluxation. Sling effectiveness was evaluated by simple shoulder AP X-rays, quantitative electromyography (root mean square; RMS), strap tension, and preference of the patient. Of the four types, the "V" strap pouch arm sling reduced the vertical displacement the most. RMS values of the supraspinatus muscle tended decrease and strap tension was also lower after using the "V" strap pouch arm sling compared with others. The patient also preferred the "V" strap pouch arm sling to the other slings. We suggested that "V" strap pouch arm sling was the most effective among four types of arm slings (including conventional hemisling) for the correction of shoulder subluxation, and patient's preference.

Effect of a newly developed abdominal webbing strap for pain relief after exploratory laparotomy in gynaecological patients.

The effect of a newly developed abdominal webbing strap for pain relief after exploratory laparotomy in gynaecological patients was studied using a quasi-experimental method. The subjects consisted of 60 patients in gynaecological wards and were randomly allocated into 2 groups as a control group and an experimental group. The experimental group was given the webbing strap when they gained consciousness after operation until 72 hours later while the control group was not. A visual analogue scale was used to evaluate the pain level experienced by the patient. The percentage changes in pain level while resting, coughing and walking were evaluated in both groups at 24, 48, and 72 hours after operation. The data were then analysed using the Student t-test. The results of the study showed no statistical difference in the decrease of pain level for either group while they were resting (P > 0.05) at every time of evaluation. On the contrary, at every time of evaluation, the pain level of the experimental group showed a greater decrease than the control group when coughing or walking which was statistically significant (P < 0.001). The quantity of analgesic usage was also not statistically different for either group (P > 0.05). As a result of this, we suggest our new developed webbing strap should be used routinely in gynaecological patients after exploratory laparotomy.

The Effect on Voice by Strap Muscle Cutting in Thyroidectomy / 대한내분비외과학회지

PURPOSE: Voice change after thyroidectomy has generally been the result of damage to the recurrent or superior laryngeal nerve. But many patients complain voice alteration without laryngeal nerve injury after thyroidectomy. The purpose of this study is to investigate whether strap muscle division results in any subjective or objective functional sequelae in voice, through long-term follow-up prospectively. METHODS: Twenty-two female patients who had undergone thyroid surgery between July 1998 and December 1999, were studied. The patients who were planned for neck dissection, who had benign laryngeal disease or vocal cord paresis, and whose vocal cord paresis were developed after thyroid surgery, were excluded from this study. Twelve patients had undergone thyroidectomy via retraction of strap muscle and ten patients had undergone thyroidectomy via cutting of strap muscle. For evaluation of voice, questionnaires for changes of voice, acoustics (fundamental frequency, jitter, shimmer, signal to noise ratio, noise to harmonic ratio, voice range), and aerodynamic (maximal phonation time) analyses were done. RESULTS: The subjective voice symptoms after thyroidectomy were disturbances of high pitch, singing, loud voice, and easy fatigue at phonation. There were no significant differences in voice parameters on acoustic and aerodynamic analyses between the strap muscle retraction group and the cutting group through long-term follow-up. CONCLUSION: We conclude that strap muscle division does not result in any subjective or objective functional problems in voice. We suggest that surgical division and reconstruction of these muscles should be employed routinely when operating on large, toxic or neoplastic glands.

Voice Comparison between Strap Muscle Retraction and Cutting Technique in Thyroidectomy / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: A voice analysis was carried out before and after thyroid surgeries without laryngeal nerve injury, between strap muscle retraction and cutting group in thyroid surgery. The study was done by means of questionaires, acoustics and aerodynamic analysis. MATERIALS AND METHODS: A total of fourty-two patients of whom thirty-eight are females and four are males were analyzed; hemithyroidectomy (19 cases) and total thyroidectomy (23 cases). Twenty-seven patients had undergone thyroidectomy via retraction of strap muscle and 15 patients had undergone thyroidectomy via cutting of strap muscle. For evaluation of voice, questionaires for changes of voice, acoustics (fundamental frequency, jitter, shimmer, noise to harmonic ratio, voice intensity, vocal range), and aerodynamic (maximal phonation time, mean flow rate and subglottal pressure) analyses were done. RESULTS: The subjective voice symptoms after thyroidectomy were disturbances of high pitch, loud voice and singing voice, and easy fatigue at phonation. These voice symptoms were related to the extent of surgery. Vocal range was the only diminished parameter in acoustic and aerodynamic analyses after thyroidectomy. There were significant differences in jitter on acoustic and aerodynamic analyses between the strap muscle retraction group and the cutting group. CONCLUSION:Voice alteration after thyroidectomy without laryngeal nerve injury may be associated with the disturbance of the extralaryngeal skeleton- laryngotracheal fixation with impairment of vertical movement or by temporal malfunction of the strap muscles. These voice problems were related to the extent of surgery and cutting of strap muscles.
