Investigating the relationship between pain level and grip and wrist muscles strength in individuals with lateral epicondylitis: is pain a barrier to strength assessment?

PURPOSE: This study was carried out to examine the relationship between rest, activity, and nighttime pain and grip and isokinetic muscle strength of the wrist muscles in individuals with lateral epicondylitis. METHODS: Fifty-six sedentary individuals aged between 18 and 65 years diagnosed with unilateral lateral epicondylitis volunteered to participate in the study. The level of rest, activity, and nighttime pain was evaluated with visual analog scale (VAS). The grip strengths of both arms were evaluated by averaging a maximum of three grip strength measurements using a hand dynamometer. The strength of both wrist flexor and extensor muscles were evaluated with isokinetic dynamometer at angular velocities of 60 and 180°/s with five and 15 concentric repetitions respectively. RESULTS: There was no significant relationship found between the affected side's grip strength and isokinetic muscle strength with rest, activity and nighttime pain (all P > 0.05). However, there was a difference observed between the affected and unaffected side in grip strength and isokinetic strength measurements of all wrist muscles (all P < 0.05); the unaffected side values were found to be higher. CONCLUSION: The result of this study found no correlation between the stated level of pain and the true muscle strength in the affected hand. In line with these findings, we think that assessments involving strength can be made in other musculoskeletal problems where pain is present. However, the findings may not reflect the true muscle strength which will tend to be underrated.

Adaptation of the International Fitness Scale and Self-Perceived Health-Related Physical Fitness Questionnaire into Turkish.

This study aims to investigate the Turkish validity and reliability of the International Fitness Scale (IFIS) and the Self-Perceived Health-Related Physical Fitness Questionnaire for Children (SPHQ-C) aged 10-17. The measurement tools were translated into Turkish by two independent researchers and back-translated. Then, the content validity was established with a group of 13 individuals (Sample 1) who presented to the sports medicine clinic. The pilot application phase was initiated. A sample of 372 individuals (Sample 2) studying in the provincial center was selected for piloting the measurement tools with the ALPHA-FIT Test Battery. The test-retest application of the measurement tools with a 15-day interval was carried out with 207 individuals (Sample 3) not included in Sample 2. The authors calculated that the content validity ratio values for the items in the IFIS ranged from 0.85 to 1.00, with a content validity index of 0.94 for the scale. In the SPHQ-C, these values were found to be between 0.92 and 1.00, with a content validity index of 0.99. According to the Z-score difference analysis for both measurement tools, the construct validity of all items was achieved (p < 0.05). In the Bland-Altman plot test conducted for the IFIS-TR, the mean difference was calculated as 0.11, the standard deviation of the differences was 1.57, and the p-value was determined as 0.31. For the SPHQ-C-TR, the mean difference was -0.15, the standard deviation of the differences was 1.95, and the p-value was determined as 0.26. The Kappa coefficients for the items of the IFIS-TR ranged from 0.45 to 0.52, while for the SPHQ-C-TR, the Kappa coefficients ranged from 0.47 to 0.75. Confirmatory factor analysis conducted on Sample 2 confirmed model fit indices with covariance among some items of the measurement tools (IFIS-TR: e1-e3; SPHQ-C-TR: e1-e2, e1-e3, e2-e3, e3-e4, e6-e7, e8-e9). The IFIS and SPHQ-C measurement tools have been adapted into Turkish, and their validity and reliability have been established.

Modified prolotherapy by 5% dextrose: Two years experiences of a traditional and complementary medicine practice center in Turkey.

BACKGROUND: Prolotherapy (PrT) is an increasingly popular regenerative injection treatment for the management of musculoskeletal injuries. The diagnostic injection is a method for selecting suitable patients to apply PrT using subcutaneous 5% dextrose solution. OBJECTIVE: The study aims to assess the PrT usage and modifications in the treatment of chronic low back pain and lumbar disc herniation and to define diagnostic injection procedure for PrT. METHOD: Two thousand three hundred and eighty-two patients with low back pain or lumbar disc herniation were evaluated at the Traditional and Complementary Medicine Practice Center in Ankara, Turkey. Six hundred fifty-four patients were included in the study. Diagnostic injections were performed on all patients who were thought to be eligible candidates for PrT indications. A 4-or-6 week interval was allowed between treatment sessions. RESULTS: Xix hundred and fifty-four patient treatments were completed. The Visual Analogue Scale (VAS) scores decreased to 5.1 ± 1.4 while 7.2 ± 1.1 before the diagnostic injection (p< 000.1). The VAS scores decreased from 7.2 ± 1.1 before the treatment to 0.9 ± 0.9 after 52 weeks of the treatment (p< 000.1). Thirty-four patients' treatments resulted in poor clinical results (5.2%), and 620 of the patients' pain improved (94.8%). CONCLUSION: PrT can be regarded as a safe way of providing a meaningful improvement in pain and musculoskeletal function compared to the initial status. Diagnostic injection is an easy way to eliminate patients and may become a favorite treatment modality. 5% dextrose is a more simple and painless solution for PrT and also has a high success.

Validity and reliability study of the Turkish version of the 'A Sport Fitness Index'.

BACKGROUND: The aim of this study was to adapt the 'Sport Fitness Index' into Turkish and to ensure its validity and reliability. METHODS: After obtaining the necessary permissions, the Sports Fitness Index was independently translated from its English original to Turkish by four different physicians specialising in sports medicine. The content validity of index v.1 was calculated using the Davis technique in sample 1 of 20 people regularly participating in sports. In sample 2 consisting of 104 athletes who had a sports-related ligament/muscle injury or applied to the sports medicine clinic for general medical examination; the validity and reliability of index v.2 were examined. ROC analysis was applied to determine the cut-off point value of the score obtained from the Turkish version of the index. RESULTS: The calculated I-CVI (lowest: 0.80, highest: 0.95) and S-CVI/Ave values (0.87) showed that the index provided content validity. Item 1 and item 10 were removed from the Turkish version of the index, as it caused a decrease in the Cronbach's alpha coefficient of the index v.2. Thus, the Cronbach's alpha coefficient of the index was calculated as 0.925. In the Turkish version of index v.2, the single-factor structure (explained variance rate 66.22%; eigenvalue 5.29) was preserved. The index provided confirmatory factor analysis model fit indices. The index provided a high level of negative correlation (r Ëƒ -.60; P = .0001) with the total score of the Physical Activity Inadequacy Scale Short Form-10 and the sub-scores of all summary components (r Ëƒ -.60; P = .0001). According to the ROC curve, the best cut-off point was 70 points with 96.6% sensitivity and 75% specificity in the Turkish version of the index. CONCLUSION: The Sports Fitness Index-TR provided its Turkish validity and reliability with its 8-item and single-factor structure. The cut-off point is accepted as 70 points.

Treatment of Osteoarthritis Secondary to Developmental Dysplasia of the Hip with Prolotherapy Injection versus a Supervised Progressive Exercise Control.

BACKGROUND Osteoarthritis secondary to developmental dysplasia of the hip (DDH) is one of the major causes of hip pain and disability. The aim of the study was to compare the effectiveness of prolotherapy (PrT) injections versus exercise protocol for the treatment of DDH. MATERIAL AND METHODS There were 46 hips of 41 patients who had osteoarthritis secondary to DDH included in this study. Patients were divided into 2 groups: treated with PrT (PrT group; n=20) and exercise (control group; n=21). Clinical outcomes were evaluated with visual analog scale for pain (VAS) and Harris hip score (HHS) at baseline, 3 weeks, 3 months, 6 months, and a minimum of 1-year follow-up. In PrT group clinical results were also compared in Crowe type I-IV hips. RESULTS Between group analysis revealed no significant between group differences at baseline. Dextrose injection recipients out performed exercise controls for VAS pain change score at 6 months (-4.6±2.6 versus -2.8±2.5; P=0.016), and 12 months (-4.5±2.4 versus -2.9±2.5; P=0.017) and for HHS at 6 months (24.2±14.0 versus 14.8±12.4; P=0.007) and 12 months (24.3±13.4 versus 16.5±11.3; P=0.018). CONCLUSIONS To our best knowledge, this study is the first regarding the effects of an injection method in the treatment of osteoarthritis secondary to DDH. According to our study, PrT is superior to exercises. PrT could provide significant improvement for clinical outcomes in DDH and might delay surgery.

The Efficacy of Extracorporeal Shock Wave Therapy for Chronic Coccydynia.

OBJECTIVE: Coccydynia is a disorder that decreases quality of life with significant functional failure. Extra-corporeal shock wave therapy (ESWT) is used to treat several painful musculoskeletal disorders. SUBJECTS AND METHODS: The medical records of 34 patients (29 females, 5 males) who had been treated with ESWT between 2017 and 2018 for chronic coccydynia were evaluated. Visual analog scale (VAS) scores were noted at the initial consultation, at each session, and during the initial and follow-up (at 6 months) examinations after the treatment. The 36-item short form (SF-36) quality of life scale survey was conducted at the beginning and end of the treatment. MRI was performed before the start of the procedure and 1 month after the end of the treatment. RESULTS: The mean VAS score was 9.6 (9-10) before the treatment and 3.4 (0-2) after the treatment (p < 0.05). The VAS score decreased to ≤3 in 79.4% of patients. Bone marrow edema regressed in 6% of patients. Significant improvement was observed in all of the SF-36 parameters, except for two. CONCLUSION: In our patient group, ESWT provided effective pain control. In order to evaluate the efficacy of ESWT more accurately and sensitively, prospective randomized studies with longer follow-up periods, in which ESWT is compared with different energy doses and different treatment methods, are needed.

Dextrose injections for failed back surgery syndrome: a consecutive case series.

PURPOSE: Patients with chronic low back pain, who do not respond to conservative treatment methods, generally undergo surgical revision operations, and sometimes an undesirable condition called failed back surgery syndrome (FBSS) may be inevitable. Hereby, dextrose is one of the regenerative methods that has gained popularity in the treatment of many musculoskeletal problems, and we aimed to present and evaluate the outcomes of 5% dextrose for the treatment of FBSS. METHODS: It has been designed as a consecutive case series. A total of 79 patients with FBSS, who had minimum 6 months of symptoms and did not respond to 3 months of conservative methods between May 2014 and March 2016, participated in the study. Prolotherapy injections were applied in posterior and lateral approaches. Visual Analog Scale (VAS) and Oswestry Disability Index (ODI) were used for the pre- and post-treatment evaluations. Patient satisfaction was assessed with using a 5-point Likert scale by phone contacting. RESULTS: There was statistically significant difference between repeated VAS and ODI measurements. CONCLUSIONS: These results may be the first step giving a lead to an undiscovered field. This treatment method should be kept in mind for FBSS patients before giving a decision of revision surgery.

Pelvic Incidence as a Prognostic Factor in Coccydynia.

AIM: To evaluate the pelvic incidence (PI) of coccydynia patients treated by different methods and to determine whether it is a risk factor or a prognostic factor. MATERIAL AND METHODS: Patients who were treated for coccydynia were evaluated retrospectively, and 110 patients were enrolled. Spinopelvic parameters were measured by using Surgimap software, and the position of the coccyx was evaluated according to the Postacchini classification. The results were compared to spinopelvic parameters of healthy population. RESULTS: The mean PI of the coccydynia patients did not differ from the healthy population, and there were no differences between treatment subgroups. The Postacchini classification showed that patients with type-3 and type-4 configurations had higher PI. When treatment groups were evaluated according to Postacchini classification, 80% of the surgery group had type-3 and type-4 configurations (50%, 30% respectively). CONCLUSION: This is the first study to evaluate the PI of coccydynia patients. Patients with higher PI were prone to having type-3 of type-4 coccyx configurations and undergoing surgical treatment.

The effectiveness of prolotherapy on failed rotator cuff repair surgery.

OBJECTIVES: The aim of the present study was to investigate the effectiveness of prolotherapy injections in the treatment of failed rotator cuff repair surgery. PATIENTS AND METHODS: Between May 2014 and March 2016, a total of 15 patients (5 males, 10 females; mean age 49.4±10.7 years; range, 33 to 71 years) with failed rotator cuff repair surgery who had at least six months of complaints and were refractory to at least of three months of conservative methods were included. Ultrasound-guided prolotherapy injections were performed under aseptic conditions, and the patients were instructed to carry out a home-based exercise program. Clinical assessment of shoulder function was performed using a visual analog scale (VAS) for pain, Shoulder Pain and Disability Index (SPADI), Western Ontario Rotator Cuff (WORC) Index, patient satisfaction and shoulder range of motion. All patients were examined at baseline, at Week 3, 6, and 12 and at the final follow-up visit. RESULTS: The intra-group comparison showed that the patients achieved significant improvements at all time points, compared to baseline as measured by VAS, SPADI, WORC index, and shoulder range of motion (p<0.001). Twelve patients (80%) reported excellent or good outcomes. CONCLUSION: Our study results show that prolotherapy is effective in the treatment of patients with failed rotator cuff repair surgery with significant improvements in the shoulder functions and pain relief.
