The Impact of Vitamin D Deficiency on Functional Recovery in Musculoskeletal Rehabilitation: A Cross-Sectional Study in a Tertiary Hospital in Riyadh

Country Saudi Arabia
Abstract Background: Vitamin D has an important function in musculoskeletal health as it affects the muscle, bone, and recovery processes. In Saudi Arabia, insufficient vitamin D levels are a public health concern even with high sun exposure, which might hinder rehabilitation of patients with musculoskeletal disorders.

Objective: To determine the relationship between serum vitamin D concentration and functional recovery of patients undergoing rehabilitation for musculoskeletal disorders at a tertiary hospital in Riyadh.

Methods: One hundred twenty adult patients with musculoskeletal disorders undergoing physical therapy were enrolled in a cross sectional study conducted from January to June, 2022. Participants were divided based on serum 25(OH)D levels as deficient (<20 ng/mL), insufficient (20–30 ng/mL), or sufficient (>30 ng/mL). Functional outcomes were measured with Timed Up and Go Test (TUG), handgrip strength, Visual Analog Scale (VAS) for pain assessment, and the Functional Independence Measure (FIM). Analysis of variance (ANOVA) and Pearson correlation tests were used in analyzing the data.

Results: Patients with adequate vitamin D levels demonstrated optimal performance across all outcomes: achieving faster TUG times (mean 12.3 sec), higher grip strength (22.1 kg), reduced pain on the VAS (mean 3.9), and greater functional independence valued at FIM 105.7. Correlation analysis also revealed significant associations of vitamin D levels with TUG (r = -0.62), grip strength (r = +0.58), pain (r = -0.55), and FIM (r = +0.65) for all p < 0.01.

Conclusion: The sufficiency of vitamin D is strongly associated with improved outcome measures in functional rehabilitation of musculoskeletal disorders. The active management and routine assessment of vitamin D levels should be part of rehabilitation programs in these clinical scenarios.
