[Relationship between proprioception and rotator muscles strength with shoulder pain of wheelchair basketball athletes]

Background and Objective: Proprioception an important role in shoulder joint function. Exercise and throat of the upper extremity are complex and skinny movements that apply a great deal of stress on the shoulder joint. This study was done to evaluate the relationship between proprioception and rotator muscles strength in dominant and non-dominant side with shoulder pain of wheelchair basketball athletes

Methods: In this descriptive-analytic study, 50 wheelchair basketball athletes were selected in non-random sampling way from wheelchair basketball gyms from Alborz and Tehran in Iran. WUSPI, MMT system and repositioning error test with felexometere were used for assessment of shoulder pain, rotator muscles strength and proprioception respectively

Results: There was a significant difference between dominant and non-dominant side rotators strength and proprioception [P<0.05]. There was a significant relationship between internal rotators strength and proprioception in dominate side with shoulder pain [P<0.05]. There was not a significant relationship between external rotators strength and proprioception in non-dominate side with shoulder pain

Conclusion: Repeated pattern of movements in the wheelchair basketball athletes at the long time causes muscle imbalance in strength shoulder joint. It is known as a risk factor in shoulder injuries

Efficacy of the reflexology and Yumeiho therapy massages on lower limb pain and balance in women with diabetic neuropathy

Background and Objective: Diabetic neuropathy is one of the most prevalent complications of diabetic micro-vascular that causing sensory loss of the legs, pain and disorder in proprioception after destroying of the lower limbs nervous system afferents consequently leads in balance disorder. This study was done to determine the effectiveness of reflexology and Yumeiho massages on lower limb pain and keep balance in females with diabetic neuropathy

Methods: In this semi-experimental study, thirty-four patients with diabetic neuropathyin lower limb non-randomly divided into reflexology, Yumeiho and control groups. Pain and balance were measured using the visual analogue scale, Sharpened Romberg and berg test respectively that were completed at baseline and after 6 weeks. Six weeks of Yumeiho and reflexology massaging were applied over 3 days in week for 30 minutes on the experimental groups

Results: Pain and balance of patients singnificantly improved in reflexology and Yumeiho groups in compared to controls [P<0.05], There was no significant difference between reflexology and Yumeiho groups

Conclusion: Reflexology and Yumeiho massages have a same impact on the pain rate and balance of lower limb in women with diabetic neuropathy

Comparison of core stabilization, theraband resistance and combined training on functional endurance and postural control in male patients with multiple sclerosis

Background and Objective: Multiple sclerosis [MS] is one of the most common diseases in the central nervous system, caused by damage to myelin sheath. This study was done to compare the effect of eight weeks of core stabilization, theraband resistance and combined training on functional endurance and postural control in male patients with MS

Methods: In this quasi-experimental study, 40 male patients with MS were non- randomly divided into three experimental and one control groups [each group, n = 10, age range 25 to 35 years, BMI between 20 and 25, and physical disability scale of 1 to 5.4]. Core stabilization, theraband resistance and combined training, balance berg test and 6-minute walk test were performed in order to exercise protocols

Results: Capacity movement and postural control were significantly improved in experimental groups in comparison with control group [P<0.05]. The most variability was related to the combination of training program

Conclusion: Eight weeks of core stabilization, theraband resistance and combined training improves functional endurance and postural control in men with MS

Electromy ographic responses of vastus muscles to dynamic postural perturbations in athletes with patellofemoral pain syndrome

Background and Aim: Patellofemoral pain syndrome [PFPS] is among the most common musculoskeletal disorders in the athletes and active individuals

Observation of muscular responses to unexpected perturbations is one of the most common methods to evaluate the neural strategies. The aim of this study was to evaluate the EMG response of vastus muscles to dynamic postural perturbations in the athletes with PFPS

Material and Method: This study included 10 male athletes with PFPS and 10 healthy male athletes. NPRS scale was used to assess pain. EMG activity of VMO and VL muscles measured during dynamic postural perturbation. The EMG signals were collected using a 16-channel BTS-FREEEMG 300 system, manufactured in Italy. Independent-1 test was used for data analysis

Results: RMS values for VMO and VL muscles in PFPS group, were higher than the corresponding values of the control group by 33.59% and 33.35% respectively, in the forward postural perturbation. There was a significant difference in VL muscle RMS values between the two groups [P=0.04]

RMS values for VMO and VL muscles in PFPS group were higher than those of the control group by 38% and 49.52% respectively, in the backward postural perturbation and there was a significant difference in VL muscle RMS values between the two groups [P=0.04]

Conclusion: The results showed that valtus muscles were more active in response to dynamic postural perturbation in the athletes with PFPS in comparison to the healthy athletes

Patellofemoral pain syndrome and in general joint disorders can lead to dysfunction in the whole sensory-motor system

Therefore, instead of focusing on local symptoms we should examine the whole body in sensory-motor system dysfunction

[Comparing the radiographic grading scales, knee pain, signs, movement dysfunctions and the quality of life related to osteoarthritis in ex-elite track and field athletes and non-athletes]

The purpose of this study was to compare the radiographic grading scales osteoarthritis, knee pain, signs and movement dysfunctions related to osteoarthritis in daily, sport and recreational activities and also the quality of life between ex-elite track and field athletes and the non-athletes. Thirty ex-elite male track and field athletes were purposefully selected and divided into two equal groups [n=15]. The clinical and radiological methods [Kellgren-Lawrence] and a global and domestic questionnaire of the knee injury and osteoarthritis outcome score [KOOS] were used to diagnose the disease. Results showed a significant lower mean for movement dysfunctions in sport and recreational activities between athletes and non-athletes [P=0.02]. Despite a 30% difference in the mean radiographic grading for osteoarthritis in athletes compared to the non-athletes, the difference was not statistically significant [P=0.90]. Moreover, the lower mean values for knee pain, signs, movement dysfunctions in daily activities and the quality of life in athletes were 10% [P=0.27], 10% [P=0.09], 12% [P=0.13] and 4% [P=0.90], respectively compared to non-athletes, however, the difference was not statistically significant. Participating in track and field competitions at the professional level may improve the movement function of ex-elite athletes
