🔬 Practice-Changing Findings
Evidence from RCTs and meta-analyses published in the
last 12 months.
|
BMC musculoskeletal disorders (2026) - Systematic Review
Key Findings
- Spurling test showed high specificity (0.84-1.00) versus sensitivity ranging from 0.38 to 0.98 across the included studies.
- Combined upper-limb neurodynamic tests showed sensitivity 0.97 versus specificity 0.51; ULNT1 showed sensitivity 0.70 versus specificity 0.71.
- The review found very low-certainty evidence and did not establish improved diagnostic accuracy for the physical-test outcomes because the evidence base was sparse.
📋 Practice Implication: Use Spurling testing chiefly as a rule-in aid and combined neurodynamic testing as a complementary rule-out signal, while keeping imaging and the overall clinical picture in the decision because certainty is very low.

British journal of sports medicine (2026) - Meta-Analysis
Key Findings
- Adults with the highest versus lowest handgrip strength had reduced odds of musculoskeletal impairment (OR 0.65, 95% CI 0.56-0.76) and disability (OR 0.57, 95% CI 0.47-0.70).
- The best versus worst five-repetition chair-stand performance was associated with reduced odds of musculoskeletal impairment (OR 0.52, 95% CI 0.37-0.74) and disability (OR 0.58, 95% CI 0.41-0.82).
- The evidence quality ranged from very low to moderate, indicating reduced confidence in the associations.
📋 Practice Implication: Consider handgrip and chair-stand testing as inexpensive functional risk-stratification measures during musculoskeletal assessment, but treat them as prognostic markers rather than standalone diagnostic tests.

The American journal of sports medicine (2026) - Systematic Review
Key Findings
- PRP did not significantly improve pain at 4 weeks (SMD 0.08; P=.526), 8-12 weeks (SMD -0.36; P=.263), or 24-26 weeks (MD -1.58; P=.328).
- Functional improvement was not significantly different from placebo at 4 weeks (SMD 0.09; P=.518), 12 weeks (SMD -0.09; P=.565), or 24-26 weeks (SMD 0.13; P=.413).
- Adverse events were not significantly increased with PRP versus placebo (RR 1.66, 95% CI 0.65-4.19; P=.287).
📋 Practice Implication: Do not routinely recommend PRP for lateral epicondylitis on the expectation of superior pain or functional benefit; discuss established conservative options and the lack of placebo-controlled efficacy instead.

BMC musculoskeletal disorders (2026) - Meta-Analysis
Key Findings
- Tr14 gel produced reduced pain AUC versus diclofenac on days 4 (mean difference -6.9; P=.05), 7 (-26.3; P=.0003), and 14 (-63.6; P<.0001).
- Percent changes from baseline in pain and function improved significantly with Tr14 gel versus diclofenac on all assessed days (all P<.05).
- For pain, the estimated number needed to treat was 12 on day 7 and 10 on day 14, with small-to-medium improvement effect sizes.
📋 Practice Implication: For grade I-II ankle sprain when a topical treatment is appropriate, Tr14 gel is a supported alternative to diclofenac within the analyzed endpoints, with the largest comparative advantage emerging after the first few days.

Scientific reports (2026) - Randomized Controlled Trial
Key Findings
- Core stability exercise produced significantly greater improvement than foot-ankle strengthening across pain, KOOS outcomes, functional tests, and distal structural measures.
- Between-group improvements exceeded minimal clinically important differences for resting pain and all KOOS subscales, and met those thresholds for the fast-paced walk and chair-stand tests.
- The stair-climb and distal structural outcomes showed improved changes beyond minimal detectable change thresholds, although the authors considered the structural changes exploratory.
📋 Practice Implication: When designing short-term knee osteoarthritis rehabilitation, prioritize proximal core stabilization alongside conventional knee exercise if the goal is broader pain and mobility improvement; interpret distal structural changes cautiously until replicated with imaging.

💡
Summary
Recent evidence emphasizes using physical examination findings as part of a probabilistic musculoskeletal assessment: Spurling testing and combined upper-limb neurodynamic tests provide complementary information for cervical radiculopathy, while handgrip and chair-stand performance offer low-burden prognostic signals. Therapeutically, PRP did not outperform placebo for lateral epicondylitis, whereas Tr14 gel showed statistically favorable pain and function outcomes after ankle sprain and core stabilization added to conventional exercise produced superior short-term knee osteoarthritis outcomes versus foot-ankle strengthening.
