Shoulder proprioception in patients with subacromial impingement syndrome.

BACKGROUND: Recently, proprioception deficits of the rotator cuff and the deltoid muscles have been suggested to play a pivotal role in the subacromial impingement syndrome (SIS). To date, there are no study has been found where the kinesthesia and joint position senses have been evaluated together in SIS. OBJECTIVE: To investigate the shoulder proprioception in patients with SIS. METHODS: Sixty-one patients with SIS and 30 healthy controls, aging between 25 and 65 years, were included in the study. Main outcome measure was proprioception, assessed with an isokinetic dynamometer. Kinesthesia, active and passive joint repositioning senses were tested at 0° and 10° external rotation. All tests were repeated 4 times and the mean of angular errors were obtained. RESULTS: The mean age was 49.14 ± 10.27 and 48.80 ± 11.09 years in patient group and in control group respectively. No significant difference was found between two groups in terms of age, gender and dominance. When involved and uninvolved shoulders of the patient group were compared, kinesthesia, active and passive joint position senses were significantly impaired in involved shoulders at all angles (P < 0.05). When involved shoulders of the patient group were compared to the control group, kinesthesia, active and passive joint position senses were significantly impaired in involved shoulders in patient group at all angles (P < 0.05) except active position sense at 0°. When uninvolved shoulders of the patient group were compared to the control group, kinesthesia at 10° was significantly impaired (P < 0.05). CONCLUSION: This study showed that shoulder proprioception was impaired in patients with SIS. This proprioceptive impairment was found not only in involved shoulders but also in uninvolved shoulders in patients with SIS.

Efficacy of paraffin bath therapy in hand osteoarthritis: a single-blinded randomized controlled trial.

OBJECTIVE: To evaluate the efficacy of paraffin bath therapy on pain, function, and muscle strength in patients with hand osteoarthritis. DESIGN: Prospective single-blinded randomized controlled trial. SETTING: Department of physical medicine and rehabilitation in a university hospital. PARTICIPANTS: Patients with bilateral hand osteoarthritis (N=56). INTERVENTIONS: Patients were randomized into 2 groups with a random number table by using block randomization with 4 patients in a block. Group 1 (n=29) had paraffin bath therapy (5 times per week, for 3-week duration) for both hands. Group 2 (n=27) was the control group. All patients were informed about joint-protection techniques, and paracetamol intake was recorded. MAIN OUTCOME MEASURES: The primary outcome measures were pain (at last 48h) at rest and during activities of daily living (ADL), assessed with a visual analog scale (0-10cm) at 12 weeks. The secondary outcome measures were the Australian Canadian Osteoarthritis Hand Index (AUSCAN) and the Dreiser Functional Index (DFI), used for subjective functional evaluation, loss of range of motion (ROM), grip and pinch strength, painful and tender joint counts, and paracetamol intake. A researcher blind to group allocation recorded the measures for both hands at baseline, 3 weeks, and 12 weeks at the hospital setting. RESULTS: At baseline, there were no significant differences between groups in any of the parameters (P>.05). After treatment, the paraffin group exhibited significant improvement in pain at rest and during ADL, ROM of the right hand, and pain and stiffness dimensions of the AUSCAN (P<.05). There was no significant improvement in functional dimension of the AUSCAN and the DFI (P>.05). The control group showed a significant deterioration in right hand grip and bilateral lateral pinch and right chuck pinch strength (P<.05), but there was no significant change in the other outcome measures. When the 2 groups were compared, pain at rest, both at 3 and 12 weeks, and the number of painful and tender joints at 12 weeks significantly decreased in the paraffin group (P<.05). Bilateral hand-grip strength and the left lateral and chuck pinch strength of the paraffin group were significantly higher than the control group at 12 weeks (P<.05). CONCLUSIONS: Paraffin bath therapy seemed to be effective both in reducing pain and tenderness and maintaining muscle strength in hand osteoarthritis. It may be regarded as a beneficial short-term therapy option, which is effective for a 12-week period.

Comparison of the efficacy of transcutaneous electrical nerve stimulation, interferential currents, and shortwave diathermy in knee osteoarthritis: a double-blind, randomized, controlled, multicenter study.

OBJECTIVE: To compare the effectiveness of transcutaneous electrical nerve stimulation (TENS), interferential currents (IFCs), and shortwave diathermy (SWD) against each other and sham intervention with exercise training and education as a multimodal package. DESIGN: A double-blind, randomized, controlled, multicenter trial. SETTING: Departments of physical medicine and rehabilitation in 4 centers. PARTICIPANTS: Patients (N=203) with knee osteoarthritis (OA). INTERVENTIONS: The patients were randomized by the principal center into the following 6 treatment groups: TENS sham, TENS, IFCs sham, IFCs, SWD sham, and SWD. All interventions were applied 5 times a week for 3 weeks. In addition, exercises and an education program were given. The exercises were carried out as part of a home-based training program after 3 weeks' supervised group exercise. MAIN OUTCOME MEASURES: Primary outcome was a visual analog scale (0-100mm) to assess knee pain. Other outcome measures were time to walk a distance of 15m, range of motion, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Nottingham Health Profile, and paracetamol intake (in grams). RESULTS: We found a significant decrease in all assessment parameters (P<.05), without a significant difference among the groups except WOMAC stiffness score and range of motion. However, the intake of paracetamol was significantly lower in each treatment group when compared with the sham groups at 3 months (P<.05). Also, the patients in the IFCs group used a lower amount of paracetamol at 6 months (P<.05) in comparison with the IFCs sham group. CONCLUSIONS: Although all groups showed significant improvements, we can suggest that the use of physical therapy agents in knee OA provided additional benefits in improving pain because paracetamol intake was significantly higher in the patients who were treated with 3 sham interventions in addition to exercise and education.

Interobserver reliability of the Turkish version of the expanded and revised gross motor function classification system.

PURPOSE: Cerebral palsy (CP) is the most common disability in childhood. The gross motor function classification system (GMFCS) has become an important tool to assess motor function in CP patient. In 2007, the expanded and revised (E&R) version of GMFCS which includes age band for youth 12-18 years of age was developed. The aim of this study was to evaluate reliability of Turkish version of expanded and revised GMCS. METHODS: We assessed interobserver reliability between two physical medicine and rehabilitation specialists in 136 children with CP and test-retest reliability within a subgroup of 48 patients. Percent agreement, intraclass correlation coefficient (ICC) and µ statistics were used to evaluate reliability. RESULT: The ICC between two physicians was 0.97 and the total agreement was 89%. This result indicates excellent agreement. The overall weighted µ was 0.86. High test-retest reliability was found (ICC: 0.94 95% confidence interval) and the total agreement was 75% for test-retest reliability. CONCLUSION: The Turkish version of the E&R GMFCS is shown to be reliable and valid for assessment of Turkish CP children.

Regional migratory osteoporosis: case report of a patient with neuropathic pain.

Regional migratory osteoporosis (RMO) is an idiopathic disorder characterized by severe periarticular pain, transient and migratory arthralgia, and osteoporosis. Osteoporosis in this disease may appear in the form of local regional osteoporosis and bone marrow edema or generalized osteoporosis. It occurs most commonly in middle-aged men and late second or third trimester pregnant women. The laboratory findings of the disease are usually normal and do not demonstrate apparent anomalies. The presence of bone marrow edema on MRI is its characteristic finding. RMO can only be separated from transient osteoporosis of hip and avascular necrosis with migration to other joints. Clinically, RMO progresses in three stages: increasing pain and disability, radiological findings (osteopenia), maximalization of symptoms, and finally, the regression of the disease and radiological changes. In this case report, we present a 29-year-old woman whose symptoms had first appeared at the second trimester of pregnancy and migrated both to the other joints in the proximo-distal direction and to the adjacent bones within the same joint. She also had symptoms such as hyperalgesia, hyperesthesia and hypertrichosis along with neuropathic pain, which she described as a burning, biting, and prickling type of pain at the right leg. The neuropathic pain of the patient was resistant to medical treatment. We believe that this case was worth reporting because of the obstinate clinical course of the patient's disease and her severe neuropathic pain that was resistant to treatment.

Clinical and functional outcomes and proprioception after a modified accelerated rehabilitation program following anterior cruciate ligament reconstruction with patellar tendon autograft.

OBJECTIVES: The aim of this study was to evaluate the clinical and functional outcomes and proprioceptive function in patients who received a modified accelerated rehabilitation program after anterior cruciate ligament (ACL) reconstruction with a patellar tendon (PT) graft. METHODS: The study included 38 patients (33 men, 5 women; mean age 27.6 ± 6.4 years; range 18 to 45 years) who underwent ACL reconstruction with a PT graft and participated in a modified accelerated rehabilitation program. Only six patients were athletes. Isokinetic strengths of concentric knee extension and flexion were measured with the Cybex isokinetic dynamometer, and static balance was tested with the Sport-KAT device. For proprioceptive assessment, active repositioning was measured at knee flexions of 40°, 20°, and 5° with an isokinetic dynamometer. Activity levels and subjective functional results were evaluated with the Tegner activity scale and Lysholm knee score, respectively. For objective functional testing, single leg hop, triple leg hop, and one-legged crossover hop tests were used. Knee stability was assessed with the Lachman test and anterior drawer test and knee range of motion was measured. The mean follow-up period was 16.2 ± 9.8 months. RESULTS: There was no graft failure during the follow-up. Twenty patients (52.6%) had hypoesthesia at the donor site and 15 patients (39.5%) had anterior knee pain. Before surgery, all the patients had positive results in the Lachman and anterior drawer tests. After surgery, the Lachman test was negative in 32 patients (84.2%), while six patients (15.8%) had grade 1 laxity. The mean Lysholm knee score showed a significant increase postoperatively (p<0.001). The mean preoperative and postoperative Tegner activity scores were not significantly different (p>0.05). There were no significant differences in the range of motion between operated and uninjured extremities (p>0.05). The two extremities were similar in proprioception and balance (p>0.05). Isokinetic quadriceps muscle strength was significantly decreased in the operated extremity only in extension at 60°/sec angular velocity (p<0.05). Other muscle strength measurements were similar in both extremities. The ratios of flexion/extension muscle strength were significantly greater in the involved extremity at all angular velocities (p<0.05). The mean performance scores of three functional tests were more than 85% of the uninvolved extremity. All the patients returned to preinjury daily activities or sports activities in 6 to 12 months postoperatively. CONCLUSION: We had satisfactory clinical, proprioceptive, and functional results in achieving dynamic and static stability of the knee with the modified accelerated rehabilitation program after ACL reconstruction with a PT graft.

Efficacy of EMG-biofeedback in knee osteoarthritis.

This study was designed to investigate the additive effect of EMG-biofeedback in rehabilitation of knee osteoarthritis. Forty patients, aged 45-70, with the diagnosis of knee osteoarthritis according to American College of Rheumatology (ACR) criteria were taken into the study. The patients were randomly assigned in two groups. One group (n = 20) received strengthening exercise program with EMG-biofeedback while the other group (n = 20) had the same exercise program without biofeedback for 3 weeks. The clinical outcome was assessed on the basis of pain with visual analog scale (VAS), function with Western Ontario McMaster Osteoarthritis Index (WOMAC) and quality of life with Nottingham Health Profile (NHP). Quadriceps strength was measured with Cybex isokinetic dynamometer, isokinetically at the angular velocities of 60 and 180 degrees /s and isometric strength at 65 degrees of knee flexion. Pain, WOMAC scores and muscle strength improved in both groups but there was no statistically significant differences between two groups (p > 0.05). In both groups physical mobility, pain scores of NHP improved significantly (p < 0.001) while in EMG-biofeedback group energy and sleep scores also improved after treatment (p < 0.05). As reported in the literature, in our study, strengthening exercises improved pain, function, muscle strength and quality of life in patients with knee osteoarthritis. But it seems that there is no significant additive effect of EMG-biofeedback to regular strengthening exercise program in these patients.

The efficacy of conservative treatment in patients with full-thickness rotator cuff tears.

Rotator cuff tears are a common cause of shoulder pain and disability. Although many studies have reported about the surgical results of full-thickness tears of the rotator cuff, there are few studies about the efficacy of conservative treatment. The aim of this study was to investigate the efficacy of conservative treatment in patients with full-thickness rotator cuff tears by using objective and subjective measurements. Twenty patients with full-thickness rotator cuff tears were included in the study. Outcome measures were range of motion, pain and function according to the shoulder index of the American Shoulder and Elbow Surgeons (ASES), Constant score, Short-Form 36 Health Survey (SF-36), isokinetic shoulder strength, and patient response. Patients were assessed at baseline and after 6 months. In addition, patients were contacted by telephone at 1 year and at 3 years for functional assessment according to ASES, and patient response. The treatment protocol included activity modification, oral nonsteroidal antiinflammatory medications, physical modalities, and a specific exercise program. Statistically significant improvements were obtained in range of motion, pain and function scores according to ASES, Constant score, SF-36 scores, and isokinetic strength (P < 0.05). At the 6-month evaluation, 11 patients (55%) reported that they were "much better", and 9 patients (45%) "better". Conservative treatment of full-thickness rotator cuff tears yields satisfactory results both subjectively and objectively.

[Physical therapy and rehabilitation in chondral lesions]. / Kondral lezyonlarda fizik tedavi ve rehabilitasyon.

Although most patients with articular cartilage defects are asymptomatic, some may have symptoms such as pain, effusion, muscle weakness, and limited range of motion. The goals of rehabilitation in chondral lesions are to relieve clinical symptoms, obtain painless full range of motion and muscle strength, and improve function. The key point in the rehabilitation program is to improve sensorimotor function and decrease pain and disability without increasing cartilage degeneration. Basic principles in the postoperative rehabilitation period are the same as those in conservative treatment. However, the rehabilitation program should be modified depending on the surgical procedure. Each phase of the rehabilitation program should be designed considering the type of surgical procedure, estimated healing time, restoration of joint mobility and muscle strength, and the extent of pain and effusion. Exposing the healing cartilage to shear stress under compression may have adverse effects on the healing process. For this reason, the early stage of rehabilitation (0-6 weeks) is comprised of passive, active-assistive and non-weight bearing range of motion exercises. Postoperative weight-bearing depends on the size, nature, and location of the lesion and the surgical procedure. Restriction in weight bearing is recommended in all treatment procedures except for cartilage debridement. For a successful outcome, open communication should exist between the rehabilitation team and the surgeon and the rehabilitation program should be individualized.

The reliability and validity of the Turkish version of the Western Ontario Rotator Cuff Index.

To adapt the Western Ontario Rotator Cuff (WORC) index for use in Turkey and to investigate its reliability and validity; the Turkish version of the WORC was developed according to the guidelines in the literature. Seventy-two patients with rotator cuff disease were administered the questionnaire and were also evaluated by using the University of California Los Angeles (UCLA) shoulder rating scale, Constant score, and Short Form (SF)-36 to test validity. The WORC questionnaire was repeated in 35 patients after a mean interval of 2.9 days (range 2-7 days) to evaluate test-retest reliability. Cronbach's alpha was calculated as 0.92 for the total questionnaire. The intraclass correlation coefficients were very high and ranged between 0.96 and 0.98 for each section. There was a significant negative correlation between the Turkish version of WORC and UCLA (r = -0.598, P < 0.01), Constant score (r = -0.630, P < 0.01), and all subscales of SF-36 (P < 0.01). The Turkish version of the WORC index is a reliable and valid instrument for use in clinical trials in patients with rotator cuff disorders.

Hypermobility syndrome increases the risk for low bone mass.

Few studies on the benign joint hypermobility syndrome suggest a tendency toward osteopenia, but there are conflicting results. We assessed bone mineral density in pre-menopausal women with hypermobility. Twenty-five consecutive Caucasian women diagnosed with benign hypermobility syndrome by Beighton score and 23 age- and sex-matched controls were included in the study. Age, menarch age, number of pregnancies, duration of lactation, physical activity and calcium intake were questioned according to European Vertebral Osteoporosis Study Group (EVOS) form. All subjects were pre-menopausal and none of them were on treatment with any drugs effecting bone metabolism or had any other systemic disease. No statistically significant difference was found for body mass index, menarch age, number of pregnancies, duration of lactation, calcium intake, calcium score and physical activity score between the two groups. Total femoral and trochanteric bone mineral density and t and z scores were significantly lower in hypermobile patients compared to the control group. Ward's triangle and femoral neck z scores were also found to be significantly low in hypermobile patients (p<0.05). Significant negative correlations were found between the Beighton scores and trochanteric BMD, t and z scores (r=-0.29, r=-0.30, and r=-0.32) in hypermobility patients. Low bone mass was more frequently found among subjects with hypermobility (p=0.03). Hypermobility was found to increase the risk for low bone mass by 1.8 times (95% confidence interval 1.01-3.38). Our study suggests that pre-menopausal women with joint hypermobility have lower bone mineral density when compared to the controls and hypermobility increases the risk for low bone mass.
