ObjectivesTo determine whether age, body mass index (BMI), hand length and forearm circumference were predictive of hand grip strength in healthy Saudi Arabian adult males.MethodsThis cross-sectional descriptive study recruited healthy adult male volunteers. Their anthropometric characteristics including age, BMI, hand length and forearm circumference were measured using routine techniques. Hand grip strength was assessed using a Jamar® Hydraulic Hand Dynamometer. The data were analysed using Pearson correlation coefficient (r) as well as by a stepwise multiple linear regression analysis.ResultsThe study included 116 healthy males who satisfied the inclusion criteria. A Pearson correlation coefficient matrix demonstrated that all the four measures, age, BMI, hand length and forearm circumference, were significantly correlated with hand grip strength. Age had an inverse correlation with hand grip strength. The anthropometric measures of hand length, age and forearm circumference accounted for 44.2% (R2 0.442) of the variation of the hand grip strength.ConclusionHand length, age and forearm circumference significantly impacted on hand grip strength in Saudi Arabian healthy adult males.
Background
Neck proprioception is critical in maintaining neuromuscular control in and around cervical joints. Kinesio™ tape may assist in rehabilitating joint position sense. The current study compares Kinesio™ tape’s effects versus a placebo on proprioception in college athletes experiencing mechanical neck pain.
Methods
This study randomized sixty-six athletes with mechanical neck pain into a Kinesio™ tape group (n = 33, mean age = 22.73 years) or placebo group (n = 33, mean age = 23.15 years). The Kinesio™ tape group received standard Kinesio™ taping applications with appropriate tension, while the placebo group received taping applications without tension. Outcome measures: The study assessed cervical joint position errors with a cervical range-of-motion (CROM) device, pain intensity with a visual analog scale (VAS), and neck functional disability with a neck disability index (NDI). It tested joint position errors through cervical flexion, extension, rotation left, and rotation right. All the outcome measures were recorded at the baseline and twice more following 3 and 7 days of tape applications.
Results
Multivariate analysis of variance test demonstrated a significant reduction in joint position errors in flexion, extension and right rotation following 3 days and 7 days of tape application among the Kinesio™ tape group. There was a significant main effect of time (P < 0.05) for joint position errors in left rotation and VAS after 3 days (p > 0.05), NDI after 3 and 7 days (p > 0.05).
Conclusions
The Kinesio™ tape application after 3 and 7 days effectively decreased joint position errors and neck pain intensity in mechanical neck pain participants compared to placebo, while there was no difference between both groups in the NDI.

BACKGROUND: Proprioception, one’s sense of movement and position, is a common term used in back rehabilitation. Kinesthetic rehabilitation may be useful in managing lower back pain; however, reliable measures are required to quantify lumbar proprioception sense. OBJECTIVE: To investigate intrarater and interrater reliability of neutral lumbar positioning (NLP) and target lumbar positioning (TLP) tests and compare the position sense errors in subjects with non-specific low back pain and healthy controls. METHODS: Intrarater (between-day) and interrater (within-day) reliability of NLP and TLP tests were assessed in 30 subjects with low back pain and 30 healthy subjects using a digital inclinometer. NLP is evaluated when the subject is repositioned to neutral from flexion, while TLP is evaluated in lumbar flexion, by bending laterally left and right. RESULTS: Intrarater reliability for NLP tests had ICC values of 0.85 and 0.89 and TLP tests had 0.78 and 0.92. Likewise, interrater reliability for NLP had ICC values of 0.75 and 0.85, and for the TLP test, the interrater reliability had 0.78 and 0.93. Subjects with back pain had significantly larger neutral and target lumbar proprioceptive errors compared to healthy controls (p< 0.001). CONCLUSIONS: Intrarater and interrater reliability showed good agreement for both NLP and TLP tests of lumbar proprioception. Subjects with nonspecific low back pain have impaired lumbar proprioceptive sense.
Background
Knee osteoarthritis (KOA) is a painful degenerative joint disease that may limit activities of daily living. This study aimed to determine the relationship between quadriceps endurance and knee joint position sense (JPS) in KOA individuals and compare the quadriceps endurance and knee JPS with and without KOA.
Methods
This comparative cross-sectional study was conducted in medical rehabilitation clinics, King Khalid University, Saudi Arabia. This study recruited 50 individuals diagnosed with unilateral KOA (mean age = 67.10 ± 4.36 years) and 50 asymptomatic individuals (mean age = 66.50 ± 3.63 years). Quadriceps isometric endurance capacity (sec) was measured using a fatigue resistance test, and knee JPS (degrees) were assessed using a digital inclinometer and evaluated in sitting and standing positions.
Results
Quadriceps isometric endurance showed a significant moderate negative correlation with knee JPS in 20° of flexion (r = -0.48, p < 0.001); 40° of flexion: r = -0.62, p < 0.001; 60° of flexion: r = -0.58, p < 0.001) in sitting and 20° of flexion (r = -0.25, p = 0.084) in standing position in KOA individuals. When compared to the asymptomatic, the quadriceps endurance was lower (p < 0.001), and knee joint position errors were larger (p < 0.001) in KOA individuals.
Conclusion
Results of this study showed that quadriceps endurance capacity is negatively associated with knee JPS. KOA individuals demonstrated lower quadriceps endurance and larger JPS compared to asymptomatic.
Evidence suggests that the application of Kinesio Tape (KT) on patients with chronic nonspecific low back pain (CNLBP) is inconclusive. Dynamic tape (DT) is a relatively new treatment technique, which is increasingly being used as an adjunctive method to treat musculoskeletal problems. To our knowledge, no study has investigated the application of DT in individuals with CNLBP. To compare the immediate and short-term effects of DT versus KT and no tape among patients with CNLBP on pain, endurance, disability, mobility, and kinesiophobia. Forty-five patients with CNLBP were randomly assigned to 1 of 3 groups. Outcomes were measured at baseline, immediately, and on the third day post-application of tapes. The primary outcomes of pain, endurance, and disability were measured through the visual analog scale (VAS), Biering-Sorensen test, and Oswestry disability index (ODI), respectively. Secondary outcome measures of mobility and kinesiophobia were measured using the modified-modified Schober test and the Tampa Scale of Kinesiophobia, respectively. No significant immediate and short-term differences were found between DT and KT in pain, disability, mobility, and kinesiophobia. Improved back extensor endurance was observed for the DT group than KT (p = 0.023) and control group (p = 0.006). The application of DT may result in improvements only in back extensor endurance among individuals with CNLBP. This finding suggests that DT controls the processes that lead to back muscle fatigue.
Constraint-induced movement therapy (CIMT) is one of the most popular treatments for enhancing upper and lower extremity motor activities and participation in patients following a stroke. However, the effect of CIMT on balance is unclear and needs further clarification. The aim of this research was to estimate the effect of CIMT on balance and functional mobility in patients after stroke. After reviewing 161 studies from search engines including Google Scholar, EBSCO, PubMed, PEDro, Science Direct, Scopus, and Web of Science, we included eight randomized controlled trials (RCT) in this study. The methodological quality of the included RCTs was verified using PEDro scoring. This systematic review showed positive effects of CIMT on balance in three studies and similar effects in five studies when compared to the control interventions such as neuro developmental treatment, modified forced-use therapy and conventional physical therapy. Furthermore, a meta-analysis indicated a statistically significant effect size by a standardized mean difference of 0.51 (P = 0.01), showing that the groups who received CIMT had improved more than the control groups. However, the meta-analysis results for functional mobility were statistically insignificant, with an effect size of −4.18 (P = 0.16), indicating that the functional mobility improvements in the investigated groups were not greater than the control group. This study’s findings demonstrated the superior effects of CIMT on balance; however, the effect size analysis of functional mobility was statistically insignificant. These findings indicate that CIMT interventions can improve balance-related motor function better than neuro developmental treatment, modified forced-use therapy and conventional physical therapy in patients after a stroke.
